Nowadays, + this assumption has been flagged as historic bad practice by IETF, and hosts + should have been updated to not make it anymore. + + Then AI_ADDRCONFIG became mostly cosmetic: it avoids phony "Protocol family + not supported" or "Host unreachable" errors while trying to connect to a dual- + stack mode from a host with no support for source address selection. + + Nowadays, on up-to-date systems, this flag is completely useless. Then again, + I understood only the very latest MacOS release is "up-to-date" with this + definition. + +commit 662ad589c5d6f03757ae57a926d3800bfb528b30 +Author: James Jones +Date: Wed May 11 23:22:22 2011 -0700 + + Insert, not append explicit xcbgen dir python path + + If a the path to the xcb python generate libs is + explicitly specified to c_client.py, insert it in + the python path list just after the local dir entry, + rather than appending it to the existing paths. + This keeps a global/distro install of xcb from + overriding a local build of the xcb proto files. + + Signed-off-by: James Jones + Signed-off-by: Jamey Sharp + +commit 294c9f455c3534d836b010dacd2e7aa62a7dde9d +Author: David Coles +Date: Fri Apr 8 17:47:05 2011 -0700 + + Add support for building with Python 3 + + Python 3 introduces some language changes that cause issues when running + c_client.py.

This file is offered as-is, +without warranty of any kind. + +Basic Installation +================== + + Briefly, the shell commands `./configure; make; make install' should +configure, build, and install this package. The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. Some packages provide this +`INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + + The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type `make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the `make install' phase executed with root + privileges. + + 5. Optionally, type `make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior `make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type `make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide `make + distcheck', which can by used by developers to test that all other + targets like `make install' and `make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. This +is known as a "VPATH" build. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple `-arch' options to the +compiler but only a single `-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the `lipo' tool if you have problems. + +Installation Names +================== + + By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the +default for these options is expressed in terms of `${prefix}', so that +specifying just `--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to `configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +`make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, `make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +`${prefix}'. Any directories that were specified during `configure', +but not in terms of `${prefix}', must each be overridden at install +time for the entire installation to be relocated. The approach of +makefile variable overrides for each directory variable is required by +the GNU Coding Standards, and ideally causes no recompilation. +However, some platforms have known limitations with the semantics of +shared libraries that end up requiring recompilation when using this +method, particularly noticeable in packages that use GNU Libtool. + + The second method involves providing the `DESTDIR' variable. For +example, `make install DESTDIR=/alternate/directory' will prepend +`/alternate/directory' before all installation names. The approach of +`DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of `${prefix}' +at `configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of `make' will be. For these packages, running `./configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with `make V=1'; while running `./configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with `make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + HP-UX `make' updates targets which have the same time stamps as +their prerequisites, which makes it generally unusable when shipped +generated files such as `configure' are involved. Use GNU `make' +instead. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its `' header file. The option `-nodtk' can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put `/usr/ucb' early in your `PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in `/usr/bin'. So, if you need `/usr/ucb' +in your `PATH', put it _after_ `/usr/bin'. + + On Haiku, software installed for all users goes in `/boot/common', +not `/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of all of the options to `configure', and exit. + +`--help=short' +`--help=recursive' + Print a summary of the options unique to this package's + `configure', and exit. The `short' variant lists options used + only in the top level, while the `recursive' variant lists options + also present in any nested packages. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--prefix=DIR' + Use DIR as the installation prefix. *note Installation Names:: + for more details, including other options available for fine-tuning + the installation locations. + +`--no-create' +`-n' + Run the configure checks, but stop before creating any output + files. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..57c3a7b --- /dev/null +++ b/Makefile.am @@ -0,0 +1,114 @@ +ACLOCAL_AMFLAGS=-I m4 + +SUBDIRS=src tests doc man + +pkgconfigdir = $(libdir)/pkgconfig + +pkgconfig_DATA = xcb.pc + +if BUILD_COMPOSITE +pkgconfig_DATA += xcb-composite.pc +endif +if BUILD_DAMAGE +pkgconfig_DATA += xcb-damage.pc +endif +if BUILD_DPMS +pkgconfig_DATA += xcb-dpms.pc +endif +if BUILD_DRI2 +pkgconfig_DATA += xcb-dri2.pc +endif +if BUILD_DRI3 +pkgconfig_DATA += xcb-dri3.pc +endif +if BUILD_GLX +pkgconfig_DATA += xcb-glx.pc +endif +if BUILD_PRESENT +pkgconfig_DATA += xcb-present.pc +endif +if BUILD_RANDR +pkgconfig_DATA += xcb-randr.pc +endif +if BUILD_RECORD +pkgconfig_DATA += xcb-record.pc +endif +if BUILD_RENDER +pkgconfig_DATA += xcb-render.pc +endif +if BUILD_RESOURCE +pkgconfig_DATA += xcb-res.pc +endif +if BUILD_SCREENSAVER +pkgconfig_DATA += xcb-screensaver.pc +endif +if BUILD_SHAPE +pkgconfig_DATA += xcb-shape.pc +endif +if BUILD_SHM +pkgconfig_DATA += xcb-shm.pc +endif +if BUILD_SYNC +pkgconfig_DATA += xcb-sync.pc +endif +if BUILD_XEVIE +pkgconfig_DATA += xcb-xevie.pc +endif +if BUILD_XFREE86_DRI +pkgconfig_DATA += xcb-xf86dri.pc +endif +if BUILD_XFIXES +pkgconfig_DATA += xcb-xfixes.pc +endif +if BUILD_XINERAMA +pkgconfig_DATA += xcb-xinerama.pc +endif +if BUILD_XINPUT +pkgconfig_DATA += xcb-xinput.pc +endif +if BUILD_XKB +pkgconfig_DATA += xcb-xkb.pc +endif +if BUILD_XPRINT +pkgconfig_DATA += xcb-xprint.pc +endif +if BUILD_SELINUX +pkgconfig_DATA += xcb-xselinux.pc +endif +if BUILD_XTEST +pkgconfig_DATA += xcb-xtest.pc +endif +if BUILD_XV +pkgconfig_DATA += xcb-xv.pc +endif +if BUILD_XVMC +pkgconfig_DATA += xcb-xvmc.pc +endif +if BUILD_GE +pkgconfig_DATA += xcb-ge.pc +endif + + +AM_TESTS_ENVIRONMENT = \ + AM_SRCDIR=${srcdir} + +TESTS=check-pc-requires + +EXTRA_DIST = \ +tools/README \ +tools/api_conv.pl \ +tools/constants \ +autogen.sh \ +$(TESTS) + +MAINTAINERCLEANFILES = ChangeLog INSTALL + +.PHONY: ChangeLog INSTALL + +INSTALL: + $(INSTALL_CMD) + +ChangeLog: + $(CHANGELOG_CMD) + +dist-hook: ChangeLog INSTALL diff --git a/Makefile.in b/Makefile.in new file mode 100644 index 0000000..09c715f --- /dev/null +++ b/Makefile.in @@ -0,0 +1,1395 @@ +# Makefile.in generated by automake 1.16.1 from Makefile.am. +# @configure_input@ + +# Copyright (C) 1994-2018 Free Software Foundation, Inc. + +# This Makefile.in is free software;

(2007-11-04) +======================== + +This release requires xcb-proto 1.1, due to the addition of the +extension-multiword attribute to the XML schema. + +This release contains several important bug fixes, summarized below. It +also contains a patch much like Novell's libxcb-sloppy-lock.diff. +Rationale from the commit message follows. The patch and this rationale +were authored by Jamey Sharp , with agreement from +Josh Triplett . + + I strongly opposed proposals like this one for a long time. + Originally I had a very good reason: libX11, when compiled to use + XCB, would crash soon after a locking correctness violation, so it + was better to have an informative assert failure than a mystifying + crash soon after. + + It took some time for me to realize that I'd changed the libX11 + implementation (for unrelated reasons) so that it could survive most + invalid locking situations, as long as it wasn't actually being used + from multiple threads concurrently. + + The other thing that has changed is that most of the code with + incorrect locking has now been fixed. The value of the assert is + accordingly lower. + + However, remaining broken callers do need to be fixed. That's why + libXCB will still noisily print a stacktrace (if possible) on each + assertion failure, even when assert isn't actually invoked to + abort() the program; and that's why aborting is still default. This + environment variable is provided only for use as a temporary + workaround for broken applications. + +Enhancements: +* Print a backtrace, if possible, on locking assertion failures. +* Skip abort() on locking assertions if LIBXCB_ALLOW_SLOPPY_LOCK is set. +* xcb_poll_for_event: Return already-read events before reading again. +* Output a configuration summary at the end of ./configure. + +Bug fixes: +* Don't hold the xlib-xcb lock while sleeping: that allows deadlock. +* Allow unix: style display names again. +* Bug #9119: test xcb_popcount +* Fix unit tests for FreeBSD +* NetBSD doesn't have AI_ADDRCONFIG: use it only if it's available. +* Require libXau >= 0.99.2; earlier versions have a broken .pc file +* Use substitition variables in xcb-xinerama.pc.in +* Update autogen.sh to one that does objdir != srcdir +* Add tools/* and autogen.sh to EXTRA_DIST. +* Doxygen can now be fully disabled if desired. + +Documentation improvements: +* Many fixes and updates to the tutorial. +* Iterators, requests, and replies get partial Doxygen documentation. + + +Release 1.0 (2006-11-23) +======================== + +The "Thanksgiving" release: We feel thankful to have it released. Five years +have passed since XCB's initial commit on September 3rd, 2001: + + +* Support IPv6. XCB now supports displays with IPv6 addresses, with or without + enclosing square brackets, or with hosts which resolve to IPv6 addresses, by + using getaddrinfo instead of gethostbyname, and by including support for + authentication for such connections. This allows such displays as "::1:1.1". + +* XCB now uses the libpthread-stubs, to properly support optional use of + pthreads even on platforms which do not have all the necessary pthread stubs + in libc or otherwise available by default. + +* Switch from the old AM_PATH_CHECK macro to pkg-config. check 0.9.4 is now + required to build XCB's unit tests. The version that we were requiring was + not actually new enough to let our unit tests compile, and the AM_PATH_CHECK + macro is now considered deprecated. We know that versions of check using + pkg-config are new enough to work, and the check dependency was optional + anyway, so we've dropped support for older versions. + +* Provide a xcb_prefetch_maximum_request_length counterpart to + xcb_get_maximum_request_length. + +* Fix Bug #5958: zero out padding bytes in requests. + +* Change xcb_connect to pass the display number to _xcb_get_auth_info, which + passes it to get_authptr. This allows get_authptr to stop hacking the + display number out of the sockaddrs of various address families, such as + port - X_TCP_PORT, or the number after the last X in the UNIX socket path. + +* Remove --with-opt and --with-debug options from configure.ac; configure + supports the use of custom CFLAGS, so please use that instead. + +* Reove support for the tag in protocol descriptions, since they + no longer use it, and since new protocol descriptions should not need it + either. + +* xcb-proto has no libraries or headers, so don't use XCBPROTO_CFLAGS or + XCBPROTO_LIBS. + +* XCB builds which use xdmcp now include it in Requires.private, to support + static linking. + +* Replace "long" with uint32_t when used for a 32-bit quantity + +* Various enhancements to the generation of documentation with Doxygen: + * Check for doxygen in configure.ac + * Fix some Doxygen warnings. + * Install documentation. + * Handle out-of-tree builds, with srcdir != builddir. xcb.doxygen now gets + generated from xcb.doxygen.in, so that it can use top_builddir and + top_srcdir to find source and to output documentation. + * Fill in PROJECT_NUMBER from @VERSION@, now that we have it readily + available via autoconf. + + +Release 1.0 RC3 (2006-11-02) +============================ + +Note: Version 0.9.4 of the test suite tool "check" provides a broken +version of the AM_PATH_CHECK macro, which causes autoconf to fail due to +insufficient quoting on the macro names it prints in its deprecation +message. We have written a patch to fix this problem, available at: + +Version 0.9.4-2 of the Debian package for check includes this patch. +Users of other distributions who want to re-autotool libxcb will need to +apply this patch, use an older version of check, or wait for a fixed +upstream version. This bug does not affect users who use the distributed +tarballs and do not re-autotool. + +* Add library support for xcb-xinerama, using new protocol description + from xcb-proto. +* In the generated protocol code, define and use constants for opcode + numbers rather than hard-coding them. +* In the API conversion script, match only XCB-namespaced XID generators + when converting to xcb_generate_id. +* Quit treating xproto specially in Makefile.am: handle it like all the + extensions. +* Generate Doxygen documentation comments in the protocol stubs, and + provide a Doxygen config file for building HTML documentation for XCB. +* Add note to xcbxlib.h that nothing except Xlib/XCB should use it. +* Extend test suite to test xcb_parse_display with NULL argument and + display in $DISPLAY. + + +Release 1.0 RC2 (2006-10-07) +============================ + +API changes +----------- + +In our announcement of XCB 1.0 RC1, we proposed two API changes for +community feedback: + + We would greatly appreciate API review in this final release + candidate period. We've had some limited feedback that our attempts + to impose static type safety on XIDs in C pose more a hindrance than + a help, so we would appreciate discussion over whether this + constitutes a "serious issue with the API". Some question also + remains of whether xcb_poll_for_event should have the out-parameter + 'error', now that XCB has a more uniform mechanism for reporting + connection errors. Speak now on these points or leave us alone. ;-) + +Since we've received feedback agreeing with our proposed changes, and no +objections or requests to keep the existing API, we made both changes +and bumped the soname to libxcb.so.1.0.0 in preparation for the release +of XCB 1.0. + +* Remove XID wrapper structures and replace them with uint32_t typedefs. + XID union types like xcb_drawable_t and xcb_fontable_t also become + uint32_t typedefs. The API conversion script now replaces xcb_*_new + with calls directly to xcb_generate_id. This change makes + xcb_generate_id part of the client API rather than the extension API, + so move xcb_generate_id from xcbext.h to xcb.h. + +* Remove the 'int *error' out-parameter for xcb_poll_for_event. + xcb_poll_for_event now shuts down the xcb_connection_t on fatal + errors; use xcb_connection_has_error to check. + +The Xlib-specific API in libxcb-xlib also changed: + +* Stop exposing the XCB IO lock for Xlib's benefit, by removing + xcb_get_io_lock from the Xlib-specific XCB API; instead, libxcb-xlib + now provides xcb_xlib_lock and xcb_xlib_unlock. + +Code generation changes +----------------------- + +* The code generator no longer implicitly imports xproto for extensions. + xcb-proto 1.0 RC2 includes the corresponding change to explicitly + import xproto in extensions that need it + +* The generated protocol headers now declare "struct foo", "union foo" + or "enum foo", not just the typedef "foo" of an unnamed + struct/union/enum type. + +Bug Fixes +--------- + +* Make Plan 7 'checked' requests work correctly. + +Documentation improvements +-------------------------- + +* Document xcb_generate_id. + +* Tutorial enhancements. + + +Release 1.0 RC1 (2006-09-25) +============================ + +The Great XCB Renaming +---------------------- + +Rename API to follow a new naming convention: + +* XCB_CONSTANTS_UPPERCASE_WITH_UNDERSCORES +* xcb_functions_lowercase_with_underscores +* xcb_types_lowercase_with_underscores_and_suffix_t +* expand all abbreviations like "req", "rep", and "iter" + +Word boundaries for the names in the protocol descriptions fall: + +* Wherever the protocol descriptions already have an underscore +* Between a lowercase letter and a subsequent uppercase letter +* Before the last uppercase letter in a string of uppercase letters + followed by a lowercase letter (such as in LSBFirst between LSB and + First) +* Before and after a string of digits (with exceptions for sized types + like xcb_char2b_t and xcb_glx_float32_t to match the stdint.h + convention) + +Also fix up some particular naming issues: + +* Rename shape_op and shape_kind to drop the "shape_" prefix, since + otherwise these types end up as xcb_shape_shape_{op,kind}_t. +* Remove leading underscores from enums in the GLX protocol description, + previously needed to ensure a word separator, but now redundant. + +This renaming breaks code written for the previous API naming +convention. The scripts in XCB's tools directory will convert code +written for the old API to use the new API; they work well enough that +we used them to convert the non-program-generated code in XCB, and when +run on the old program-generated code, they almost exactly reproduce the +new program-generated code (modulo whitespace and bugs in the old code +generator). + +Authors: Vincent Torri, Thomas Hunger, Josh Triplett + +In addition to the API renaming, the library SONAMEs have changed to +libxcb.so and libxcb-extname.so. The library major version remains at 0, +to become version 1 before 1.0 is released; the SONAME lowercasing means +that this will not conflict with XCB 0.9 libraries. + +The header files have moved from /usr/include/X11/XCB/ to +/usr/include/xcb/. The XML-XCB protocol descriptions have moved to +/usr/share/xcb, with extension descriptions no longer relegated to an +extensions/ subdirectory. The API conversion script api_conv.pl will fix +references to the header files, and packages using pkg-config will +automatically use the new library names. + +Error handling Plan 7 +--------------------- + +All request functions now come in an "unchecked" and "checked" variant. +The checked variant allows callers to handle errors inline where they +obtain the reply, or by calling xcb_request_check for requests with no +reply. The unchecked variant uses the event queue for errors. Requests +with replies default to checked, because the caller must already make a +function call to retrieve the reply and can see the error at that time; +the unchecked variant uses the suffix _unchecked. Requests without +replies default to unchecked, because the caller will not necessarily +expect to handle a response, and the checked variant uses the suffix +_checked. + +Connection error handling +------------------------- + +Fatal connection errors now put the xcb_connection_t object into an +error state, at which point all further operations on that connection +will fail. Callers can use the new xcb_connection_has_error function to +check for this state in a connection. Functions that return a +connection, such as the xcb_connect function, may instead return an +xcb_connection_t already in an error state. + +In the future we expect to add additional API for getting more +information about the error condition that caused the connection to get +into an error state. + +Smaller API changes +------------------- + +All functions that have been marked 'deprecated' up to now have been +removed for this release. After XCB 1.0 is released, functions marked +'deprecated' will be preserved until the end of time to maintain +compatibility. + +XCB no longer provides a sync function. Most callers of this function +should use xcb_flush instead, which usually provides the intended +functionality and does not require a round-trip to the server. If you +really need this functionality, either use xcb_get_input_focus like sync +used to do, or use the xcb_aux_sync function from the xcb-aux library in +xcb-util. However, note that we do not consider the libraries in +xcb-util remotely stable yet. + +XCB no longer provides xcb_[extension_name]_init functions for each +extension. These functions previously caused XCB to issue and process a +QueryExtension request. Callers should now directly call +xcb_get_extension_data on the xcb_[extension_name]_id, or use +xcb_prefetch_extension_data if they do not need to force a round-trip +immediately. + +The compatibility functions in xcbxlib.h, provided solely for use by +Xlib/XCB, now exist in a separate library libxcb-xlib. We don't want to +have to change the libxcb soname if we later change or remove the Xlib +compatibility functions, and nothing except Xlib/XCB should ever use +them. (Applications which use Xlib/XCB do not need this library either; +Xlib/XCB only uses it internally.) + +The descriptions of several extensions have been updated to match the +latest versions implemented in the X.org X server. + +GIT Repository split +-------------------- + +Previously, several XCB-related projects all existed under the umbrella +of a single monolithic GIT repository with per-project subdirectories. +We have split this repository into individual per-project repositories. + +Josh Triplett and Jamey Sharp wrote a tool called git-split to +accomplish this repository split. git-split reconstructs the history of +a sub-project previously stored in a subdirectory of a larger +repository. It constructs new commit objects based on the existing tree +objects for the subtree in each commit, and discards commits which do +not affect the history of the sub-project, as well as merges made +unnecessary due to these discarded commits. + +We would like to acknowledge the work of the gobby team in creating a +collaborative editor which greatly aided the development of git-split +(as well as these release notes). + +Build and implementation fixes +------------------------------ + +XCB no longer needs proto/x11 from X.org; the XCB header xproto.h +provides the definitions from X.h, named according to XCB conventions. + +XCB should now build with non-GNU implementations of Make. + +XCB properly handles 32-bit wrap of sequence numbers, and thus now +supports issuing more than 2**32 requests in one connection. + +Fixed bugs #7001, #7261. diff --git a/README b/README new file mode 100644 index 0000000..167c8ac --- /dev/null +++ b/README @@ -0,0 +1,36 @@ +About libxcb +============ + +libxcb provides an interface to the X Window System protocol, which +replaces the current Xlib interface.

  1. Introduction +

    + This tutorial is based on the + Xlib Tutorial + written by Guy Keren. The + author allowed me to take some parts of his text, mainly the text which + deals with the X Windows generality. +

    +

    + This tutorial is intended for people who want to start to program + with the XCB + library. keep in mind that XCB, like the + Xlib + library, isn't what most programmers wanting to write X + applications are looking for. They should use a much higher + level GUI toolkit like Motif, + LessTiff, + GTK, + QT, + EWL, + ETK, or use + Cairo. + However, + we need to start somewhere. More than this, knowing how things + work down below is never a bad idea. +

    +

    + After reading this tutorial, one should be able to write very + simple graphical programs, but not programs with decent user + interfaces. For such programs, one of the previously mentioned + libraries should be used. +

    +

    + But what is XCB? Xlib has been + the standard C binding for the X + Window System protocol for many years now. It is an + excellent piece of work, but there are applications for which it + is not ideal, for example: +

    +
      +
    • Small platforms: Xlib is a large piece of code, and + it's difficult to make it smaller +
    • Latency hiding: Xlib requests requiring a reply are + effectively synchronous: they block until the reply appears, + whether the result is needed immediately or not. +
    • Direct access to the protocol: Xlib does quite a + bit of caching, layering, and similar optimizations. While this + is normally a feature, it makes it difficult to simply emit + specified X protocol requests and process specific + responses. +
    • Threaded applications: While Xlib does attempt to + support multithreading, the API makes this difficult and + error-prone. +
    • New extensions: The Xlib infrastructure provides + limited support for the new creation of X extension client side + code. +
    +

    + For these reasons, among others, XCB, an X C binding, has been + designed to solve the above problems and thus provide a base for +

    +
      +
    • Toolkit implementation. +
    • Direct protocol-level programming. +
    • Lightweight emulation of commonly used portions of the + Xlib API. +
    +
    +
  2. The client and server model of the X window system +

    + The X Window System was developed with one major goal: + flexibility. The idea was that the way things look is one thing, + but the way things work is another matter. Thus, the lower + levels provide the tools required to draw windows, handle user + input, allow drawing graphics using colors (or black and white + screens), etc. To this point, a decision was made to separate + the system into two parts. A client that decides what to do, and + a server that actually draws on the screen and reads user input + in order to send it to the client for processing. +

    +

    + This model is the complete opposite of what is used to when + dealing with clients and servers. In our case, the user sits + near the machine controlled by the server, while the client + might be running on a remote machine. The server controls the + screens, mouse and keyboard. A client may connect to the server, + request that it draws a window (or several windows), and ask the + server to send it any input the user sends to these + windows. Thus, several clients may connect to a single X server + (one might be running mail software, one running a WWW + browser, etc). When input is sent by the user to some window, + the server sends a message to the client controlling this window + for processing. The client decides what to do with this input, + and sends the server requests for drawing in the window. +

    +

    + The whole session is carried out using the X message + protocol. This protocol was originally carried over the TCP/IP + protocol suite, allowing the client to run on any machine + connected to the same network that the server is. Later on, the + X servers were extended to allow clients running on the local + machine with more optimized access to the server (note that an X + protocol message may be several hundreds of KB in size), such as + using shared memory, or using Unix domain sockets (a method for + creating a logical channel on a Unix system between two processes). +

    +
  3. GUI programming: the asynchronous model +

    + Unlike conventional computer programs, that carry some serial + nature, a GUI program usually uses an asynchronous programming + model, also known as "event-driven programming". This means that + that program mostly sits idle, waiting for events sent by the X + server, and then acts upon these events. An event may say "The + user pressed the 1st button mouse in spot (x,y)", or "The window + you control needs to be redrawn". In order for the program to be + responsive to the user input, as well as to refresh requests, it + needs to handle each event in a rather short period of time + (e.g. less that 200 milliseconds, as a rule of thumb). +

    +

    + This also implies that the program may not perform operations + that might take a long time while handling an event (such as + opening a network connection to some remote server, or + connecting to a database server, or even performing a long file + copy operation). Instead, it needs to perform all these + operations in an asynchronous manner. This may be done by using + various asynchronous models to perform the longish operations, + or by performing them in a different process or thread. +

    +

    + So the way a GUI program looks is something like that: +

    +
      +
    1. Perform initialization routines. +
    2. Connect to the X server. +
    3. Perform X-related initialization. +
    4. While not finished: +
        +
      1. Receive the next event from the X server. +
      2. Handle the event, possibly sending various drawing + requests to the X server. +
      3. If the event was a quit message, exit the loop. +
      +
    5. Close down the connection to the X server. +
    6. Perform cleanup operations. +
    +
    +
  4. Basic XCB notions +

    + XCB has been created to eliminate the need for + programs to actually implement the X protocol layer. This + library gives a program a very low-level access to any X + server. Since the protocol is standardized, a client using any + implementation of XCB may talk with any X server (the same + occurs for Xlib, of course). We now give a brief description of + the basic XCB notions. They will be detailed later. +

    +
      +
    1. The X Connection +

      + The major notion of using XCB is the X Connection. This is a + structure representing the connection we have open with a + given X server. It hides a queue of messages coming from the + server, and a queue of pending requests that our client + intends to send to the server. In XCB, this structure is named + 'xcb_connection_t'. It is analogous to the Xlib Display. + When we open a connection to an X server, the + library returns a pointer to such a structure. Later, we + supply this pointer to any XCB function that should send + messages to the X server or receive messages from this server. +

      +
    2. Requests and + replies: the Xlib killers +

      + To ask for information from the X server, we have to make a request + and ask for a reply. With Xlib, these two tasks are + automatically done: Xlib locks the system, sends a request, + waits for a reply from the X server and unlocks. This is + annoying, especially if one makes a lot of requests to the X + server. Indeed, Xlib has to wait for the end of a reply + before asking for the next request (because of the locks that + Xlib sends). For example, here is a time-line of N=4 + requests/replies with Xlib, with a round-trip latency + T_round_trip that is 5 times long as the time required + to write or read a request/reply (T_write/T_read): +

      + 
      +  W-----RW-----RW-----RW-----R
+
      +
        +
      • W: Writing request +
      • -: Stalled, waiting for data +
      • R: Reading reply +
      +

      + The total time is N * (T_write + T_round_trip + T_read). +

      +

      + With XCB, we can suppress most of the round-trips as the + requests and the replies are not locked. We usually send a + request, then XCB returns to us a cookie, which is an + identifier. Then, later, we ask for a reply using this + cookie and XCB returns a + pointer to that reply. Hence, with XCB, we can send a lot of + requests, and later in the program, ask for all the replies + when we need them. Here is the time-line for 4 + requests/replies when we use this property of XCB: +

      + 
      +  WWWW--RRRR
+
      +

      + The total time is N * T_write + max (0, T_round_trip - (N-1) * + T_write) + N * T_read. Which can be considerably faster than + all those Xlib round-trips. +

      +

      + Here is a program that computes the time to create 500 atoms + with Xlib and XCB. It shows the Xlib way, the bad XCB way + (which is similar to Xlib) and the good XCB way. On my + computer, XCB is 25 times faster than Xlib. +

      +
    3. The Graphic Context +

      + When we perform various drawing operations (graphics, text, + etc), we may specify various options for controlling how the + data will be drawn (what foreground and background colors to + use, how line edges will be connected, what font to use when + drawing some text, etc). In order to avoid the need to supply + hundreds of parameters to each drawing function, a graphical + context structure is used. We set the various drawing options + in this structure, and then we pass a pointer to this + structure to any drawing routines. This is rather handy, as we + often need to perform several drawing requests with the same + options. Thus, we would initialize a graphical context, set + the desired options, and pass this structure to all drawing + functions. +

      +

      + Note that graphic contexts have no client-side structure in + XCB, they're just XIDs. Xlib has a client-side structure + because it caches the GC contents so it can avoid making + redundant requests, but of course XCB doesn't do that. +

      +
    4. Events +

      + A structure is used to pass events received from the X + server. XCB supports exactly the events specified in the + protocol (33 events). This structure contains the type + of event received (including a bit for whether it came + from the server or another client), as well as the data associated with the + event (e.g. position on the screen where the event was + generated, mouse button associated with the event, region of + the screen associated with a "redraw" event, etc). The way to + read the event's data depends on the event type. +

      +
    +
    +
  5. Using XCB-based programs +
    +
      +
    1. Installation of XCB +

      + TODO: These instructions are out of date. + Just reference the main XCB page + so we don't have to maintain these instructions in more than + one place. +

      +

      + To build XCB from source, you need to have installed at + least: +

      + +

      + You have to checkout in the git repository the following modules: +

      +
        +
      • Xau from xlibs +
      • xcb-proto +
      • xcb +
      +

      + Note that xcb-proto exists only to install header + files, so typing 'make' or 'make all' will produce the message + "Nothing to be done for 'all'". That's normal. +

      +
    2. Compiling XCB-based programs +

      + Compiling XCB-based programs requires linking them with the XCB + library. This is easily done thanks to pkgconfig: +

      + 
      +gcc -Wall prog.c -o prog `pkg-config --cflags --libs xcb`
+
      +
    +
  6. Opening and closing the connection to an X server +

    + An X program first needs to open the connection to the X + server. There is a function that opens a connection. It requires + the display name, or NULL. In the latter case, the display name + will be the one in the environment variable DISPLAY. +

    + 
    +xcb_connection_t *xcb_connect (const char *displayname,
+                               int        *screenp);
+
    +

    + The second parameter returns the screen number used for the + connection. The returned structure describes an XCB connection + and is opaque. Here is how the connection can be opened: +

    + 
    +#include <xcb/xcb.h>
+
+int
+main ()
+{
+  xcb_connection_t *c;
+
+  /* Open the connection to the X server. Use the DISPLAY environment variable as the default display name */
+  c = xcb_connect (NULL, NULL);
+
+  return 0;
+}
+
    +

    + To close a connection, it suffices to use: +

    + 
    +void xcb_disconnect (xcb_connection_t *c);
+
    +
    +
    + Comparison Xlib/XCB +
    +
    +
      +
    • XOpenDisplay () +
    +
    +
    +
      +
    • xcb_connect () +
    +
    +
    +
      +
    • XCloseDisplay () +
    +
    +
    +
      +
    • xcb_disconnect () +
    +
    +
    +
    +
  7. Checking basic information about a connection +

    + Once we have opened a connection to an X server, we should check some + basic information about it: what screens it has, what is the + size (width and height) of the screen, how many colors it + supports (black and white ? grey scale ?, 256 colors ? more ?), + and so on. We get such information from the xcb_screen_t + structure: +

    + 
    +typedef struct {
+    xcb_window_t   root;
+    xcb_colormap_t default_colormap;
+    uint32_t       white_pixel;
+    uint32_t       black_pixel;
+    uint32_t       current_input_masks;
+    uint16_t       width_in_pixels;
+    uint16_t       height_in_pixels;
+    uint16_t       width_in_millimeters;
+    uint16_t       height_in_millimeters;
+    uint16_t       min_installed_maps;
+    uint16_t       max_installed_maps;
+    xcb_visualid_t root_visual;
+    uint8_t        backing_stores;
+    uint8_t        save_unders;
+    uint8_t        root_depth;
+    uint8_t        allowed_depths_len;
+} xcb_screen_t;
+
    +

    + We could retrieve the first screen of the connection by using the + following function: +

    + 
    +xcb_screen_iterator_t xcb_setup_roots_iterator (xcb_setup_t *R);
+
    +

    + Here is a small program that shows how to use this function: +

    + 
    +#include <stdio.h>
+
+#include <xcb/xcb.h>
+
+int
+main ()
+{
+  xcb_connection_t     *c;
+  xcb_screen_t         *screen;
+  int                   screen_nbr;
+  xcb_screen_iterator_t iter;
+
+  /* Open the connection to the X server. Use the DISPLAY environment variable */
+  c = xcb_connect (NULL, &screen_nbr);
+
+  /* Get the screen #screen_nbr */
+  iter = xcb_setup_roots_iterator (xcb_get_setup (c));
+  for (; iter.rem; --screen_nbr, xcb_screen_next (&iter))
+    if (screen_nbr == 0) {
+      screen = iter.data;
+      break;
+    }
+
+  printf ("\n");
+  printf ("Informations of screen %ld:\n", screen->root);
+  printf ("  width.........: %d\n", screen->width_in_pixels);
+  printf ("  height........: %d\n", screen->height_in_pixels);
+  printf ("  white pixel...: %ld\n", screen->white_pixel);
+  printf ("  black pixel...: %ld\n", screen->black_pixel);
+  printf ("\n");
+
+  return 0;
+}
+
    +
  8. Creating a basic window - the "hello world" program +

    + After we got some basic information about our screen, we can + create our first window. In the X Window System, a window is + characterized by an Id. So, in XCB, a window is of type: +

    + 
    +typedef uint32_t xcb_window_t;
+
    +

    + We first ask for a new Id for our window, with this function: +

    + 
    +xcb_window_t xcb_generate_id(xcb_connection_t *c);
+
    +

    + Then, XCB supplies the following function to create new windows: +

    + 
    +xcb_void_cookie_t xcb_create_window (xcb_connection_t *c,             /* Pointer to the xcb_connection_t structure */
+                                     uint8_t           depth,         /* Depth of the screen */
+                                     xcb_window_t      wid,           /* Id of the window */
+                                     xcb_window_t      parent,        /* Id of an existing window that should be the parent of the new window */
+                                     int16_t           x,             /* X position of the top-left corner of the window (in pixels) */
+                                     int16_t           y,             /* Y position of the top-left corner of the window (in pixels) */
+                                     uint16_t          width,         /* Width of the window (in pixels) */
+                                     uint16_t          height,        /* Height of the window (in pixels) */
+                                     uint16_t          border_width,  /* Width of the window's border (in pixels) */
+                                     uint16_t          _class,
+                                     xcb_visualid_t    visual,
+                                     uint32_t          value_mask,
+                                     const uint32_t   *value_list);
+
    +

    + The fact that we created the window does not mean that it will + be drawn on screen. By default, newly created windows are not + mapped on the screen (they are invisible). In order to make our + window visible, we use the function xcb_map_window(), whose + prototype is +

    + 
    +xcb_void_cookie_t xcb_map_window (xcb_connection_t *c,
+                                  xcb_window_t      window);
+
    +

    + Finally, here is a small program to create a window of size + 150x150 pixels, positioned at the top-left corner of the screen: +

    + 
    +#include <unistd.h>      /* pause() */
+
+#include <xcb/xcb.h>
+
+int
+main ()
+{
+  xcb_connection_t *c;
+  xcb_screen_t     *screen;
+  xcb_window_t      win;
+
+  /* Open the connection to the X server */
+  c = xcb_connect (NULL, NULL);
+
+  /* Get the first screen */
+  screen = xcb_setup_roots_iterator (xcb_get_setup (c)).data;
+
+  /* Ask for our window's Id */
+  win = xcb_generate_id(c);
+
+  /* Create the window */
+  xcb_create_window (c,                             /* Connection          */
+                     XCB_COPY_FROM_PARENT,          /* depth (same as root)*/
+                     win,                           /* window Id           */
+                     screen->root,                  /* parent window       */
+                     0, 0,                          /* x, y                */
+                     150, 150,                      /* width, height       */
+                     10,                            /* border_width        */
+                     XCB_WINDOW_CLASS_INPUT_OUTPUT, /* class               */
+                     screen->root_visual,           /* visual              */
+                     0, NULL);                      /* masks, not used yet */
+
+  /* Map the window on the screen */
+  xcb_map_window (c, win);
+
+  /* Make sure commands are sent before we pause, so window is shown */
+  xcb_flush (c);
+
+  pause ();    /* hold client until Ctrl-C */
+
+  return 0;
+}
+
    +

    + In this code, you see one more function - xcb_flush(), not explained + yet. It is used to flush all the pending requests. More + precisely, there are 2 functions that do such things. The first + one is xcb_flush(): +

    + 
    +int xcb_flush (xcb_connection_t *c);
+
    +

    + This function flushes all pending requests to the X server (much + like the fflush() function is used to + flush standard output). The second function is + xcb_aux_sync(): +

    + 
    +int xcb_aux_sync (xcb_connection_t *c);
+
    +

    + This functions also flushes all pending requests to the X + server, and then waits until the X server finishing processing + these requests. In a normal program, this will not be necessary + (we'll see why when we get to write a normal X program), but for + now, we put it there. +

    +

    + The window that is created by the above code has a non defined + background. This one can be set to a specific color, + thanks to the two last parameters of + xcb_create_window(), which are not + described yet. See the subsections + Configuring a window or + Registering for event types using event masks + for examples on how to use these parameters. In addition, as no + events are handled, you have to make a Ctrl-C to interrupt the + program. +

    +

    + TODO: one should tell what these functions return and + about the generic error +

  9. Drawing in a window +

    + Drawing in a window can be done using various graphical + functions (drawing pixels, lines, rectangles, etc). In order to + draw in a window, we first need to define various general + drawing parameters (what line width to use, which color to draw + with, etc). This is done using a graphical context. +

    +
      +
    1. Allocating a Graphics Context +

      + As we said, a graphical context defines several attributes to + be used with the various drawing functions. For this, we + define a graphical context. We can use more than one graphical + context with a single window, in order to draw in multiple + styles (different colors, different line widths, etc). In XCB, + a Graphics Context is, as a window, characterized by an Id: +

      + 
      +typedef uint32_t xcb_gcontext_t;
+
      +

      + We first ask the X server to attribute an Id to our graphic + context with this function: +

      + 
      +xcb_gcontext_t xcb_generate_id (xcb_connection_t *c);
+
      +

      + Then, we set the attributes of the graphic context with this function: +

      + 
      +xcb_void_cookie_t xcb_create_gc (xcb_connection_t *c,
+                                 xcb_gcontext_t    cid,
+                                 xcb_drawable_t    drawable,
+                                 uint32_t          value_mask,
+                                 const uint32_t   *value_list);
+
      +

      + We give now an example on how to allocate a graphic context + that specifies that each drawing function that uses it will + draw in foreground with a black color. +

      + 
      +#include <xcb/xcb.h>
+
+int
+main ()
+{
+  xcb_connection_t *c;
+  xcb_screen_t     *screen;
+  xcb_drawable_t    win;
+  xcb_gcontext_t    black;
+  uint32_t          mask;
+  uint32_t          value[1];
+
+  /* Open the connection to the X server and get the first screen */
+  c = xcb_connect (NULL, NULL);
+  screen = xcb_setup_roots_iterator (xcb_get_setup (c)).data;
+
+  /* Create a black graphic context for drawing in the foreground */
+  win = screen->root;
+  black = xcb_generate_id (c);
+  mask = XCB_GC_FOREGROUND;
+  value[0] = screen->black_pixel;
+  xcb_create_gc (c, black, win, mask, value);
+
+  return 0;
+}
+
      +

      + Note should be taken regarding the role of "value_mask" and + "value_list" in the prototype of xcb_create_gc(). Since a + graphic context has many attributes, and since we often just + want to define a few of them, we need to be able to tell the + xcb_create_gc() which attributes we + want to set. This is what the "value_mask" parameter is + for. We then use the "value_list" parameter to specify actual + values for the attribute we defined in "value_mask". Thus, for + each constant used in "value_list", we will use the matching + constant in "value_mask". In this case, we define a graphic + context with one attribute: when drawing (a point, a line, + etc), the foreground color will be black. The rest of the + attributes of this graphic context will be set to their + default values. +

      +

      + See the next Subsection for more details. +

      +
      +
      +
      +
    2. Changing the attributes of a Graphics Context +

      + Once we have allocated a Graphic Context, we may need to + change its attributes (for example, changing the foreground + color we use to draw a line, or changing the attributes of the + font we use to display strings. See Subsections Drawing with a + color and + Assigning a Font to a Graphic Context). + This is done by using this function: +

      + 
      +xcb_void_cookie_t xcb_change_gc (xcb_connection_t *c,           /* The XCB Connection */
+                                 xcb_gcontext_t    gc,          /* The Graphic Context */
+                                 uint32_t          value_mask,  /* Components of the Graphic Context that have to be set */
+                                 const uint32_t   *value_list); /* Value as specified by value_mask */
+
      +

      + The value_mask parameter could take + any combination of these masks from the xcb_gc_t enumeration: +

      + It is possible to set several attributes at the same + time (for example setting the attributes of a font and the + color which will be used to display a string), by OR'ing these + values in value_mask. Then + value_list has to be an array which + lists the value for the respective attributes. These values + must be in the same order as masks listed above. See Subsection + Drawing with a color to have an example. +

    3. Drawing primitives: point, line, box, circle,... +

      + After we have created a Graphic Context, we can draw on a + window using this Graphic Context, with a set of XCB + functions, collectively called "drawing primitives". Let see + how they are used. +

      +

      + To draw a point, or several points, we use +

      + 
      +xcb_void_cookie_t xcb_poly_point (xcb_connection_t  *c,               /* The connection to the X server */
+                                  uint8_t            coordinate_mode, /* Coordinate mode, usually set to XCB_COORD_MODE_ORIGIN */
+                                  xcb_drawable_t     drawable,        /* The drawable on which we want to draw the point(s) */
+                                  xcb_gcontext_t     gc,              /* The Graphic Context we use to draw the point(s) */
+                                  uint32_t           points_len,      /* The number of points */
+                                  const xcb_point_t *points);         /* An array of points */
+
      +

      + The coordinate_mode parameter + specifies the coordinate mode. Available values are +

      +
        +
      • XCB_COORD_MODE_ORIGIN +
      • XCB_COORD_MODE_PREVIOUS +
      +

      + If XCB_COORD_MODE_PREVIOUS is used, then all points but the first one + are relative to the immediately previous point. +

      +

      + The xcb_point_t type is just a + structure with two fields (the coordinates of the point): +

      + 
      +typedef struct {
+    int16_t x;
+    int16_t y;
+} xcb_point_t;
+
      +

      + You could see an example in xpoints.c. TODO Set the link. +

      +

      + To draw a line, or a polygonal line, we use +

      + 
      +xcb_void_cookie_t xcb_poly_line (xcb_connection_t  *c,               /* The connection to the X server */
+                                 uint8_t            coordinate_mode, /* Coordinate mode, usually set to XCB_COORD_MODE_ORIGIN */
+                                 xcb_drawable_t     drawable,        /* The drawable on which we want to draw the line(s) */
+                                 xcb_gcontext_t     gc,              /* The Graphic Context we use to draw the line(s) */
+                                 uint32_t           points_len,      /* The number of points in the polygonal line */
+                                 const xcb_point_t *points);         /* An array of points */
+
      +

      + This function will draw the line between the first and the + second points, then the line between the second and the third + points, and so on. +

      +

      + To draw a segment, or several segments, we use +

      + 
      +xcb_void_cookie_t xcb_poly_segment (xcb_connection_t    *c,              /* The connection to the X server */
+                                    xcb_drawable_t       drawable,       /* The drawable on which we want to draw the segment(s) */
+                                    xcb_gcontext_t       gc,             /* The Graphic Context we use to draw the segment(s) */
+                                    uint32_t             segments_len,   /* The number of segments */
+                                    const xcb_segment_t *segments);      /* An array of segments */
+
      +

      + The xcb_segment_t type is just a + structure with four fields (the coordinates of the two points + that define the segment): +

      + 
      +typedef struct {
+    int16_t x1;
+    int16_t y1;
+    int16_t x2;
+    int16_t y2;
+} xcb_segment_t;
+
      +

      + To draw a rectangle, or several rectangles, we use +

      + 
      +xcb_void_cookie_t xcb_poly_rectangle (xcb_connection_t      *c,              /* The connection to the X server */
+                                      xcb_drawable_t         drawable,       /* The drawable on which we want to draw the rectangle(s) */
+                                      xcb_gcontext_t         gc,             /* The Graphic Context we use to draw the rectangle(s) */
+                                      uint32_t               rectangles_len, /* The number of rectangles */
+                                      const xcb_rectangle_t *rectangles);    /* An array of rectangles */
+
      +

      + The xcb_rectangle_t type is just a + structure with four fields (the coordinates of the top-left + corner of the rectangle, and its width and height): +

      + 
      +typedef struct {
+    int16_t  x;
+    int16_t  y;
+    uint16_t width;
+    uint16_t height;
+} xcb_rectangle_t;
+
      + + +

      + To draw an elliptical arc, or several elliptical arcs, we use +

      + 
      +xcb_void_cookie_t xcb_poly_arc (xcb_connection_t *c,          /* The connection to the X server */
+                                xcb_drawable_t    drawable,   /* The drawable on which we want to draw the arc(s) */
+                                xcb_gcontext_t    gc,         /* The Graphic Context we use to draw the arc(s) */
+                                uint32_t          arcs_len,   /* The number of arcs */
+                                const xcb_arc_t  *arcs);      /* An array of arcs */
+
      +

      + The xcb_arc_t type is a structure with + six fields: +

      + 
      +typedef struct {
+    int16_t  x;       /* Top left x coordinate of the rectangle surrounding the ellipse */
+    int16_t  y;       /* Top left y coordinate of the rectangle surrounding the ellipse */
+    uint16_t width;   /* Width of the rectangle surrounding the ellipse */
+    uint16_t height;  /* Height of the rectangle surrounding the ellipse */
+    int16_t  angle1;  /* Angle at which the arc begins */
+    int16_t  angle2;  /* Angle at which the arc ends */
+} xcb_arc_t;
+
      +
      +

      + Note: the angles are expressed in units of 1/64 of a degree, + so to have an angle of 90 degrees, starting at 0, + angle1 = 0 and + angle2 = 90 << 6. Positive angles + indicate counterclockwise motion, while negative angles + indicate clockwise motion. +

      +
      + + +

      + The corresponding function which fill inside the geometrical + object are listed below, without further explanation, as they + are used as the above functions. +

      +

      + To Fill a polygon defined by the points given as arguments , + we use +

      + 
      +xcb_void_cookie_t xcb_fill_poly (xcb_connection_t  *c,
+                                 xcb_drawable_t     drawable,
+                                 xcb_gcontext_t     gc,
+                                 uint8_t            shape,
+                                 uint8_t            coordinate_mode,
+                                 uint32_t           points_len,
+                                 const xcb_point_t *points);
+
      +

      + The shape parameter specifies a + shape that helps the server to improve performance. Available + values are +

      +
        +
      • XCB_POLY_SHAPE_COMPLEX +
      • XCB_POLY_SHAPE_NONCONVEX +
      • XCB_POLY_SHAPE_CONVEX +
      +

      + To fill one or several rectangles, we use +

      + 
      +xcb_void_cookie_t xcb_poly_fill_rectangle (xcb_connection_t      *c,
+                                           xcb_drawable_t         drawable,
+                                           xcb_gcontext_t         gc,
+                                           uint32_t               rectangles_len,
+                                           const xcb_rectangle_t *rectangles);
+
      +

      + To fill one or several arcs, we use +

      + 
      +xcb_void_cookie_t xcb_poly_fill_arc (xcb_connection_t *c,
+                                     xcb_drawable_t    drawable,
+                                     xcb_gcontext_t    gc,
+                                     uint32_t          arcs_len,
+                                     const xcb_arc_t  *arcs);
+
      +
      + +

      + To illustrate these functions, here is an example that draws + four points, a polygonal line, two segments, two rectangles + and two arcs. Remark that we use events for the first time, as + an introduction to the next section. +

  10. X Events +

    + In an X program, everything is driven by events. Event painting + on the screen is sometimes done as a response to an event (an + Expose event). If part of a program's + window that was hidden, gets exposed (e.g. the window was raised + above other widows), the X server will send an "expose" event to + let the program know it should repaint that part of the + window. User input (key presses, mouse movement, etc) is also + received as a set of events. +

    +
      +
    1. Registering for event types using event masks +

      + During the creation of a window, you should give it what kind + of events it wishes to receive. Thus, you may register for + various mouse (also called pointer) events, keyboard events, + expose events, and so on. This is done for optimizing the + server-to-client connection (i.e. why send a program (that + might even be running at the other side of the globe) an event + it is not interested in ?) +

      +

      + In XCB, you use the "value_mask" and "value_list" data in the + xcb_create_window() function to + register for events. Here is how we register for + Expose event when creating a window: +

      + 
      +  mask = XCB_CW_EVENT_MASK;
+  valwin[0] = XCB_EVENT_MASK_EXPOSURE;
+  win = xcb_generate_id (c);
+  xcb_create_window (c, depth, win, root->root,
+                     0, 0, 150, 150, 10,
+                     XCB_WINDOW_CLASS_INPUT_OUTPUT, root->root_visual,
+                     mask, valwin);
+
      +

      + XCB_EVENT_MASK_EXPOSURE is a constant defined + in the xcb_event_mask_t enumeration in the "xproto.h" header file. If we wanted to register for several + event types, we can logically "or" them, as follows: +

      + 
      +  mask = XCB_CW_EVENT_MASK;
+  valwin[0] = XCB_EVENT_MASK_EXPOSURE | XCB_EVENT_MASK_BUTTON_PRESS;
+  win = xcb_generate_id (c);
+  xcb_create_window (c, depth, win, root->root,
+                     0, 0, 150, 150, 10,
+                     XCB_WINDOW_CLASS_INPUT_OUTPUT, root->root_visual,
+                     mask, valwin);
+
      +

      + This registers for Expose events as + well as for mouse button presses inside the created + window. You should note that a mask may represent several + event sub-types. +

      +

      + The values that a mask could take are given + by the xcb_cw_t enumeration: +

      + 
      +typedef enum {
+    XCB_CW_BACK_PIXMAP       = 1L<<0,
+    XCB_CW_BACK_PIXEL        = 1L<<1,
+    XCB_CW_BORDER_PIXMAP     = 1L<<2,
+    XCB_CW_BORDER_PIXEL      = 1L<<3,
+    XCB_CW_BIT_GRAVITY       = 1L<<4,
+    XCB_CW_WIN_GRAVITY       = 1L<<5,
+    XCB_CW_BACKING_STORE     = 1L<<6,
+    XCB_CW_BACKING_PLANES    = 1L<<7,
+    XCB_CW_BACKING_PIXEL     = 1L<<8,
+    XCB_CW_OVERRIDE_REDIRECT = 1L<<9,
+    XCB_CW_SAVE_UNDER        = 1L<<10,
+    XCB_CW_EVENT_MASK        = 1L<<11,
+    XCB_CW_DONT_PROPAGATE    = 1L<<12,
+    XCB_CW_COLORMAP          = 1L<<13,
+    XCB_CW_CURSOR            = 1L<<14
+} xcb_cw_t;
+
      +
      +

      Note: we must be careful when setting the values of the valwin + parameter, as they have to follow the order the + xcb_cw_t enumeration. Here is an + example: +

      +
      + 
      +  mask = XCB_CW_EVENT_MASK | XCB_CW_BACK_PIXMAP;
+  valwin[0] = XCB_NONE;                                              /* for XCB_CW_BACK_PIXMAP (whose value is 1)     */
+  valwin[1] = XCB_EVENT_MASK_EXPOSURE | XCB_EVENT_MASK_BUTTON_PRESS; /* for XCB_CW_EVENT_MASK, whose value (2048)     */
+                                                                     /* is greater than the one of XCB_CW_BACK_PIXMAP */
+
      +

      + If the window has already been created, we can use the + xcb_change_window_attributes() function to set + the events that the window will receive. The subsection + Configuring a window shows its + prototype. As an example, here is a piece of code that + configures the window to receive the + Expose and + ButtonPress events: +

      + 
      +const static uint32_t values[] = { XCB_EVENT_MASK_EXPOSURE | XCB_EVENT_MASK_BUTTON_PRESS };
+
+/* The connection c and the window win are supposed to be defined */
+
+xcb_change_window_attributes (c, win, XCB_CW_EVENT_MASK, values);
+
      +
      +

      + Note: A common bug programmers have is adding code to handle new + event types in their program, while forgetting to add the + masks for these events in the creation of the window. Such a + programmer would then sit there for hours debugging their + program, wondering "Why doesn't my program notice that I + released the button?", only to find that they registered for + button press events but not for button release events. +

      +
      +
    2. Receiving events: writing the events loop +

      + After we have registered for the event types we are interested + in, we need to enter a loop of receiving events and handling + them. There are two ways to receive events: a blocking way and + a non-blocking way: +

      +
        +
      • + xcb_wait_for_event (xcb_connection_t *c) + is the blocking way. It waits (so blocks...) until an event is + queued in the X server. Then it retrieves it into a newly + allocated structure (it dequeues it from the queue) and returns + it. This structure has to be freed. The function returns + NULL if an error occurs. + +
        +
      • + xcb_poll_for_event (xcb_connection_t *c, int + *error) is the non-blocking way. It looks at the event + queue and returns (and dequeues too) an existing event into + a newly allocated structure. This structure has to be + freed. It returns NULL if there is + no event. If an error occurs, the parameter error will be filled with the error + status. +
      +

      + There are various ways to write such a loop. We present two + ways to write such a loop, with the two functions above. The + first one uses xcb_wait_for_event_t, which + is similar to an event Xlib loop using only XNextEvent: +

      + 
      +  xcb_generic_event_t *e;
+
+  while ((e = xcb_wait_for_event (c))) {
+    switch (e->response_type & ~0x80) {
+    case XCB_EXPOSE: {
+      /* Handle the Expose event type */
+      xcb_expose_event_t *ev = (xcb_expose_event_t *)e;
+
+      /* ... */
+
+      break;
+    }
+    case XCB_BUTTON_PRESS: {
+      /* Handle the ButtonPress event type */
+      xcb_button_press_event_t *ev = (xcb_button_press_event_t *)e;
+
+      /* ... */
+
+      break;
+    }
+    default: {
+      /* Unknown event type, ignore it */
+      break;
+    }
+    }
+    /* Free the Generic Event */
+    free (e);
+  }
+
      +

      + You will certainly want to use xcb_poll_for_event(xcb_connection_t *c, int + *error) if, in Xlib, you use XPending or + XCheckMaskEvent: +

      + 
      +  while (XPending (display)) {
+    XEvent ev;
+
+    XNextEvent(d, &ev);
+
+    /* Manage your event */
+  }
+
      +

      + Such a loop in XCB looks like: +

      + 
      +  xcb_generic_event_t *ev;
+
+  while ((ev = xcb_poll_for_event (conn, 0))) {
+    /* Manage your event */
+  }
+
      +

      + The events are managed in the same way as with xcb_wait_for_event_t. + Obviously, we will need to give the user some way of + terminating the program. This is usually done by handling a + special "quit" event, as we will soon see. +

      +
      +

      +
      +
      +
    3. Expose events +

      + The Expose event is one of the most + basic (and most used) events an application may receive. It + will be sent to us in one of several cases: +

      +
        +
      • A window that covered part of our window has moved + away, exposing part (or all) of our window. +
      • Our window was raised above other windows. +
      • Our window mapped for the first time. +
      • Our window was de-iconified. +
      +

      + You should note the implicit assumption hidden here: the + contents of our window is lost when it is being obscured + (covered) by either windows. One may wonder why the X server + does not save this contents. The answer is: to save + memory. After all, the number of windows on a display at a + given time may be very large, and storing the contents of all + of them might require a lot of memory. Actually, there is a + way to tell the X server to store the contents of a window in + special cases, as we will see later. +

      +

      + When we get an Expose event, we + should take the event's data from the members of the following + structure: +

      + 
      +typedef struct {
+    uint8_t      response_type; /* The type of the event, here it is XCB_EXPOSE */
+    uint8_t      pad0;
+    uint16_t     sequence;
+    xcb_window_t window;        /* The Id of the window that receives the event (in case */
+                                /* our application registered for events on several windows */
+    uint16_t     x;             /* The x coordinate of the top-left part of the window that needs to be redrawn */
+    uint16_t     y;             /* The y coordinate of the top-left part of the window that needs to be redrawn */
+    uint16_t     width;         /* The width of the part of the window that needs to be redrawn */
+    uint16_t     height;        /* The height of the part of the window that needs to be redrawn */
+    uint16_t     count;
+} xcb_expose_event_t;
+
      +
    4. Getting user input +

      + User input traditionally comes from two sources: the mouse + and the keyboard. Various event types exist to notify us of + user input (a key being presses on the keyboard, a key being + released on the keyboard, the mouse moving over our window, + the mouse entering (or leaving) our window, and so on. +

      +
        +
      1. Mouse button press and release events +

        + The first event type we will deal with is a mouse + button-press (or button-release) event in our window. In + order to register to such an event type, we should add one + (or more) of the following masks when we create our window: +

        +
          +
        • XCB_EVENT_MASK_BUTTON_PRESS: notify us + of any button that was pressed in one of our windows. +
        • XCB_EVENT_MASK_BUTTON_RELEASE: notify us + of any button that was released in one of our windows. +
        +

        + The structure to be checked for in our events loop is the + same for these two events, and is the following: +

        + 
        +typedef struct {
+    uint8_t         response_type; /* The type of the event, here it is xcb_button_press_event_t or xcb_button_release_event_t */
+    xcb_button_t    detail;
+    uint16_t        sequence;
+    xcb_timestamp_t time;          /* Time, in milliseconds the event took place in */
+    xcb_window_t    root;
+    xcb_window_t    event;
+    xcb_window_t    child;
+    int16_t         root_x;
+    int16_t         root_y;
+    int16_t         event_x;       /* The x coordinate where the mouse has been pressed in the window */
+    int16_t         event_y;       /* The y coordinate where the mouse has been pressed in the window */
+    uint16_t        state;         /* A mask of the buttons (or keys) during the event */
+    uint8_t         same_screen;
+} xcb_button_press_event_t;
+
+typedef xcb_button_press_event_t xcb_button_release_event_t;
+
        +

        + The time field may be used to calculate "double-click" + situations by an application (e.g. if the mouse button was + clicked two times in a duration shorter than a given amount + of time, assume this was a double click). +

        +

        + The state field is a mask of the buttons held down during + the event. It is a bitwise OR of any of the following (from the xcb_button_mask_t and + xcb_mod_mask_t enumerations): +

        +
          +
        • XCB_BUTTON_MASK_1 +
        • XCB_BUTTON_MASK_2 +
        • XCB_BUTTON_MASK_3 +
        • XCB_BUTTON_MASK_4 +
        • XCB_BUTTON_MASK_5 +
        • XCB_MOD_MASK_SHIFT +
        • XCB_MOD_MASK_LOCK +
        • XCB_MOD_MASK_CONTROL +
        • XCB_MOD_MASK_1 +
        • XCB_MOD_MASK_2 +
        • XCB_MOD_MASK_3 +
        • XCB_MOD_MASK_4 +
        • XCB_MOD_MASK_5 +
        +

        + Their names are self explanatory, where the first 5 refer to + the mouse buttons that are being pressed, while the rest + refer to various "special keys" that are being pressed (Mod1 + is usually the 'Alt' key or the 'Meta' key). +

        +

        + TODO: Problem: it seems that the state does not + change when clicking with various buttons. +

        +
      2. Mouse movement events +

        + Similar to mouse button press and release events, we also + can be notified of various mouse movement events. These can + be split into two families. One is of mouse pointer + movement while no buttons are pressed, and the second is a + mouse pointer motion while one (or more) of the buttons are + pressed (this is sometimes called "a mouse drag operation", + or just "dragging"). The following event masks may be added + during the creation of our window: +

        +
          +
        • XCB_EVENT_MASK_POINTER_MOTION: events of + the pointer moving in one of the windows controlled by our + application, while no mouse button is held pressed. +
        • XCB_EVENT_MASK_BUTTON_MOTION: Events of + the pointer moving while one or more of the mouse buttons + is held pressed. +
        • XCB_EVENT_MASK_BUTTON_1_MOTION: same as + XCB_EVENT_MASK_BUTTON_MOTION, but only when + the 1st mouse button is held pressed. +
        • XCB_EVENT_MASK_BUTTON_2_MOTION, + XCB_EVENT_MASK_BUTTON_3_MOTION, + XCB_EVENT_MASK_BUTTON_4_MOTION, + XCB_EVENT_MASK_BUTTON_5_MOTION: same as + XCB_EVENT_MASK_BUTTON_1_MOTION, but + respectively for 2nd, 3rd, 4th and 5th mouse button. +
        +

        + The structure to be checked for in our events loop is the + same for these events, and is the following: +

        + 
        +typedef struct {
+    uint8_t         response_type; /* The type of the event */
+    uint8_t         detail;
+    uint16_t        sequence;
+    xcb_timestamp_t time;          /* Time, in milliseconds the event took place in */
+    xcb_window_t    root;
+    xcb_window_t    event;
+    xcb_window_t    child;
+    int16_t         root_x;
+    int16_t         root_y;
+    int16_t         event_x;       /* The x coordinate of the mouse when the  event was generated */
+    int16_t         event_y;       /* The y coordinate of the mouse when the  event was generated */
+    uint16_t        state;         /* A mask of the buttons (or keys) during the event */
+    uint8_t         same_screen;
+} xcb_motion_notify_event_t;
+
        +
      3. Mouse pointer enter and leave events +

        + Another type of event that applications might be interested + in, is a mouse pointer entering a window the program + controls, or leaving such a window. Some programs use these + events to show the user that the application is now in + focus. In order to register for such an event type, we + should add one (or more) of the following masks when we + create our window: +

        +
          +
        • xcb_event_enter_window_t: notify us + when the mouse pointer enters any of our controlled + windows. +
        • xcb_event_leave_window_t: notify us + when the mouse pointer leaves any of our controlled + windows. +
        +

        + The structure to be checked for in our events loop is the + same for these two events, and is the following: +

        + 
        +typedef struct {
+    uint8_t         response_type; /* The type of the event */
+    uint8_t         detail;
+    uint16_t        sequence;
+    xcb_timestamp_t time;          /* Time, in milliseconds the event took place in */
+    xcb_window_t    root;
+    xcb_window_t    event;
+    xcb_window_t    child;
+    int16_t         root_x;
+    int16_t         root_y;
+    int16_t         event_x;       /* The x coordinate of the mouse when the  event was generated */
+    int16_t         event_y;       /* The y coordinate of the mouse when the  event was generated */
+    uint16_t        state;         /* A mask of the buttons (or keys) during the event */
+    uint8_t         mode;          /* The number of mouse button that was clicked */
+    uint8_t         same_screen_focus;
+} xcb_enter_notify_event_t;
+
+typedef xcb_enter_notify_event_t xcb_leave_notify_event_t;
+
        +
      4. The keyboard focus +

        + There may be many windows on a screen, but only a single + keyboard attached to them. How does the X server then know + which window should be sent a given keyboard input ? This is + done using the keyboard focus. Only a single window on the + screen may have the keyboard focus at a given time. There + is a XCB function that allows a program to set the keyboard + focus to a given window. The user can usually set the + keyboard focus using the window manager (often by clicking + on the title bar of the desired window). Once our window + has the keyboard focus, every key press or key release will + cause an event to be sent to our program (if it registered + for these event types...). +

        +
      5. Keyboard press and release events +

        + If a window controlled by our program currently holds the + keyboard focus, it can receive key press and key release + events. So, we should add one (or more) of the following + masks when we create our window: +

        +
          +
        • XCB_EVENT_MASK_KEY_PRESS: notify us when + a key was pressed while any of our controlled windows had + the keyboard focus. +
        • XCB_EVENT_MASK_KEY_RELEASE: notify us + when a key was released while any of our controlled + windows had the keyboard focus. +
        +

        + The structure to be checked for in our events loop is the + same for these two events, and is the following: +

        + 
        +typedef struct {
+    uint8_t         response_type; /* The type of the event */
+    xcb_keycode_t   detail;
+    uint16_t        sequence;
+    xcb_timestamp_t time;          /* Time, in milliseconds the event took place in */
+    xcb_window_t    root;
+    xcb_window_t    event;
+    xcb_window_t    child;
+    int16_t         root_x;
+    int16_t         root_y;
+    int16_t         event_x;
+    int16_t         event_y;
+    uint16_t        state;
+    uint8_t         same_screen;
+} xcb_key_press_event_t;
+
+typedef xcb_key_press_event_t xcb_key_release_event_t;
+
        +

        + The detail field refers to the + physical key on the keyboard. +

        +

        + TODO: Talk about getting the ASCII code from the key code. +

        +
      +
    5. X events: a complete example +

      + As an example for handling events, we show a program that + creates a window, enters an events loop and checks for all the + events described above, and writes on the terminal the relevant + characteristics of the event. With this code, it should be + easy to add drawing operations, like those which have been + described above. +

      +

  11. Handling text and fonts +

    + Besides drawing graphics on a window, we often want to draw + text. Text strings have two major properties: the characters to + be drawn and the font with which they are drawn. In order to + draw text, we need to first request the X server to load a + font. We then assign a font to a Graphic Context, and finally, we + draw the text in a window, using the Graphic Context. +

    +
      +
    1. The Font structure +

      + In order to support flexible fonts, a font type is + defined. You know what ? It's an Id: +

      + 
      +typedef uint32_t xcb_font_t;
+
      +

      + It is used to contain information about a font, and is passed + to several functions that handle fonts selection and text drawing. + We ask the X server to attribute an Id to our font with the + function: +

      + 
      +xcb_font_t xcb_generate_id (xcb_connection_t *c);
+
      +
      +
    2. Opening a Font +

      + To open a font, we use the following function: +

      + 
      +xcb_void_cookie_t xcb_open_font (xcb_connection_t *c,
+                                 xcb_font_t        fid,
+                                 uint16_t          name_len,
+                                 const char       *name);
+
      +

      + The fid parameter is the font Id + defined by xcb_generate_id() (see + above). The name parameter is the + name of the font you want to open. Use the command + xlsfonts in a terminal to know which + are the fonts available on your computer. The parameter + name_len is the length of the name + of the font (given by strlen()). +

      +
    3. Assigning a Font to a Graphic Context +

      + Once a font is opened, you have to create a Graphic Context + that will contain the informations about the color of the + foreground and the background used when you draw a text in a + Drawable. Here is an example of a Graphic Context that will + allow us to draw an opened font with a black foreground and a + white background: +

      + 
      +  /*
+   * c is the connection
+   * screen is the screen where the window is displayed
+   * window is the window in which we will draw the text
+   * font is the opened font
+   */
+
+  uint32_t             value_list[3];
+  xcb_gcontext_t       gc;
+  uint32_t             mask;
+
+  gc = xcb_generate_id (c);
+  mask = XCB_GC_FOREGROUND | XCB_GC_BACKGROUND | XCB_GC_FONT;
+  value_list[0] = screen->black_pixel;
+  value_list[1] = screen->white_pixel;
+  value_list[2] = font;
+  xcb_create_gc (c, gc, window, mask, value_list);
+
+  /* The font is not needed anymore, so we close it */
+  xcb_close_font (c, font);
+
      +
    4. Drawing text in a drawable +

      + To draw a text in a drawable, we use the following function: +

      + 
      +xcb_void_cookie_t xcb_image_text_8 (xcb_connection_t *c,
+                                    uint8_t           string_len,
+                                    xcb_drawable_t    drawable,
+                                    xcb_gcontext_t    gc,
+                                    int16_t           x,
+                                    int16_t           y,
+                                    const char       *string);
+
      +

      + The string parameter is the text to + draw. The location of the drawing is given by the parameters + x and y. + The base line of the text is exactly the parameter + y. +

      +
    5. Complete example +

      + This example draw a text at 10 pixels (for the base line) of + the bottom of a window. Pressing the Esc key exits the program. +

  12. Interacting with the window manager +

    + After we have seen how to create windows and draw on them, we + take one step back, and look at how our windows are interacting + with their environment (the full screen and the other + windows). First of all, our application needs to interact with + the window manager. The window manager is responsible to + decorating drawn windows (i.e. adding a frame, an iconify + button, a system menu, a title bar, etc), as well as handling + icons shown when windows are being iconified. It also handles + ordering of windows on the screen, and other administrative + tasks. We need to give it various hints as to how we want it to + treat our application's windows. +

    +
      +
    1. Window properties +

      + Many of the parameters communicated to the window manager are + passed using data called "properties". These properties are + attached by the X server to different windows, and are stored + in a format that makes it possible to read them from different + machines that may use different architectures (remember that + an X client program may run on a remote machine). +

      +

      + The property and its type (a string, an integer, etc) are + Id. Their type are xcb_atom_t: +

      + 
      +typedef uint32_t xcb_atom_t;
+
      +

      + To change the property of a window, we use the following + function: +

      + 
      +xcb_void_cookie_t xcb_change_property (xcb_connection_t *c,       /* Connection to the X server */
+                                       uint8_t          mode,     /* Property mode */
+                                       xcb_window_t     window,   /* Window */
+                                       xcb_atom_t       property, /* Property to change */
+                                       xcb_atom_t       type,     /* Type of the property */
+                                       uint8_t          format,   /* Format of the property (8, 16, 32) */
+                                       uint32_t         data_len, /* Length of the data parameter */
+                                       const void      *data);    /* Data */
+
      +

      + The mode parameter could be one of + the following values (defined in enumeration xcb_prop_mode_t in + the xproto.h header file): +

      +
        +
      • XCB_PROP_MODE_REPLACE +
      • XCB_PROP_MODE_PREPEND +
      • XCB_PROP_MODE_APPEND +
      +
      +
    2. Setting the window name and icon name +

      + The first thing we want to do would be to set the name for our + window. This is done using the + xcb_change_property() function. This + name may be used by the window manager as the title of the + window (in the title bar), in a task list, etc. The property + atom to use to set the name of a window is + WM_NAME (and + WM_ICON_NAME for the iconified + window) and its type is STRING. Here + is an example of utilization: +

      + 
      +#include <string.h>
+
+#include <xcb/xcb.h>
+#include <xcb/xcb_atom.h>
+
+int
+main ()
+{
+  xcb_connection_t *c;
+  xcb_screen_t     *screen;
+  xcb_window_t      win;
+  char             *title = "Hello World !";
+  char             *title_icon = "Hello World ! (iconified)";
+
+
+
+  /* Open the connection to the X server */
+  c = xcb_connect (NULL, NULL);
+
+  /* Get the first screen */
+  screen = xcb_setup_roots_iterator (xcb_get_setup (c)).data;
+
+  /* Ask for our window's Id */
+  win = xcb_generate_id (c);
+
+  /* Create the window */
+  xcb_create_window (c,                             /* Connection          */
+                     0,                             /* depth               */
+                     win,                           /* window Id           */
+                     screen->root,                  /* parent window       */
+                     0, 0,                          /* x, y                */
+                     250, 150,                      /* width, height       */
+                     10,                            /* border_width        */
+                     XCB_WINDOW_CLASS_INPUT_OUTPUT, /* class               */
+                     screen->root_visual,           /* visual              */
+                     0, NULL);                      /* masks, not used     */
+
+  /* Set the title of the window */
+  xcb_change_property (c, XCB_PROP_MODE_REPLACE, win,
+                       WM_NAME, STRING, 8,
+                       strlen (title), title);
+
+  /* Set the title of the window icon */
+  xcb_change_property (c, XCB_PROP_MODE_REPLACE, win,
+                       WM_ICON_NAME, STRING, 8,
+                       strlen(title_icon), title_icon);
+
+  /* Map the window on the screen */
+  xcb_map_window (c, win);
+
+  xcb_flush (c);
+
+  while (1) {}
+
+  return 0;
+}
+
      +
      +

      Note: the use of the atoms needs our program to be compiled + and linked against xcb_atom, so that we have to use +

      +
      + 
      +gcc prog.c -o prog `pkg-config --cflags --libs xcb_atom`
+
      +
      +

      + for the program to compile fine. +

      +
      +
    +
  13. Simple window operations +

    + One more thing we can do to our window is manipulate them on the + screen (resize them, move them, raise or lower them, iconify + them, and so on). Some window operations functions are supplied + by XCB for this purpose. +

    +
      +
    1. Mapping and un-mapping a window +

      + The first pair of operations we can apply on a window is + mapping it, or un-mapping it. Mapping a window causes the + window to appear on the screen, as we have seen in our simple + window program example. Un-mapping it causes it to be removed + from the screen (although the window as a logical entity still + exists). This gives the effect of making a window hidden + (unmapped) and shown again (mapped). For example, if we have a + dialog box window in our program, instead of creating it every + time the user asks to open it, we can create the window once, + in an un-mapped mode, and when the user asks to open it, we + simply map the window on the screen. When the user clicked the + 'OK' or 'Cancel' button, we simply un-map the window. This is + much faster than creating and destroying the window, however, + the cost is wasted resources, both on the client side, and on + the X server side. +

      +

      + To map a window, you use the following function: +

      + 
      +xcb_void_cookie_t xcb_map_window (xcb_connection_t *c,
+                                  xcb_window_t      window);
+
      +

      + To have a simple example, see the example + above. The mapping operation will cause an + Expose event to be sent to our + application, unless the window is completely covered by other + windows. +

      +

      + Un-mapping a window is also simple. You use the function +

      + 
      +xcb_void_cookie_t xcb_unmap_window (xcb_connection_t *c,
+                                    xcb_window_t      window);
+
      +

      + The utilization of this function is the same as + xcb_map_window(). +

      +
    2. Configuring a window +

      + As we have seen when we have created our first window, in the + X Events subsection, we can set some attributes for the window + (that is, the position, the size, the events the window will + receive, etc). If we want to modify them, but the window is + already created, we can change them by using the following + function: +

      + 
      +xcb_void_cookie_t xcb_configure_window (xcb_connection_t *c,            /* The connection to the X server*/
+                                        xcb_window_t      window,       /* The window to configure */
+                                        uint16_t          value_mask,   /* The mask */
+                                        const uint32_t   *value_list);  /* The values to set */
+
      +

      + We set the value_mask to one or + several mask values that are in the xcb_config_window_t enumeration in the xproto.h header: +

      +
        +
      • XCB_CONFIG_WINDOW_X: new x coordinate of the window's top left corner +
      • XCB_CONFIG_WINDOW_Y: new y coordinate of the window's top left corner +
      • XCB_CONFIG_WINDOW_WIDTH: new width of the window +
      • XCB_CONFIG_WINDOW_HEIGHT: new height of the window +
      • XCB_CONFIG_WINDOW_BORDER_WIDTH: new width of the border of the window +
      • XCB_CONFIG_WINDOW_SIBLING +
      • XCB_CONFIG_WINDOW_STACK_MODE: the new stacking order +
      +

      + We then give to value_mask the new + value. We now describe how to use + xcb_configure_window_t in some useful + situations. +

      +
    3. Moving a window around the screen +

      + An operation we might want to do with windows is to move them + to a different location. This can be done like this: +

      + 
      +const static uint32_t values[] = { 10, 20 };
+
+/* The connection c and the window win are supposed to be defined */
+
+/* Move the window to coordinates x = 10 and y = 20 */
+xcb_configure_window (c, win, XCB_CONFIG_WINDOW_X | XCB_CONFIG_WINDOW_Y, values);
+
      +

      + Note that when the window is moved, it might get partially + exposed or partially hidden by other windows, and thus we + might get Expose events due to this + operation. +

      +
    4. Resizing a window +

      + Yet another operation we can do is to change the size of a + window. This is done using the following code: +

      + 
      +const static uint32_t values[] = { 200, 300 };
+
+/* The connection c and the window win are supposed to be defined */
+
+/* Resize the window to width = 10 and height = 20 */
+xcb_configure_window (c, win, XCB_CONFIG_WINDOW_WIDTH | XCB_CONFIG_WINDOW_HEIGHT, values);
+
      +

      + We can also combine the move and resize operations using one + single call to xcb_configure_window_t: +

      + 
      +const static uint32_t values[] = { 10, 20, 200, 300 };
+
+/* The connection c and the window win are supposed to be defined */
+
+/* Move the window to coordinates x = 10 and y = 20 */
+/* and resize the window to width = 10 and height = 20 */
+xcb_configure_window (c, win, XCB_CONFIG_WINDOW_X | XCB_CONFIG_WINDOW_Y | XCB_CONFIG_WINDOW_WIDTH | XCB_CONFIG_WINDOW_HEIGHT, values);
+
      +
    5. Changing windows stacking order: raise and lower +

      + Until now, we changed properties of a single window. We'll see + that there are properties that relate to the window and other + windows. One of them is the stacking order. That is, the order + in which the windows are layered on top of each other. The + front-most window is said to be on the top of the stack, while + the back-most window is at the bottom of the stack. Here is + how to manipulate our windows stack order: +

      + 
      +const static uint32_t values[] = { XCB_STACK_MODE_ABOVE };
+
+/* The connection c and the window win are supposed to be defined */
+
+/* Move the window on the top of the stack */
+xcb_configure_window (c, win, XCB_CONFIG_WINDOW_STACK_MODE, values);
+
      + 
      +const static uint32_t values[] = { XCB_STACK_MODE_BELOW };
+
+/* The connection c and the window win are supposed to be defined */
+
+/* Move the window on the bottom of the stack */
+xcb_configure_window (c, win, XCB_CONFIG_WINDOW_STACK_MODE, values);
+
      +
    6. Getting information about a window +

      + Just like we can set various attributes of our windows, we can + also ask the X server supply the current values of these + attributes. For example, we can check where a window is + located on the screen, what is its current size, whether it is + mapped or not, etc. The structure that contains some of this + information is +

      + 
      +typedef struct {
+    uint8_t      response_type;
+    uint8_t      depth;         /* depth of the window */
+    uint16_t     sequence;
+    uint32_t     length;
+    xcb_window_t root;          /* Id of the root window *>
+    int16_t      x;             /* X coordinate of the window's location */
+    int16_t      y;             /* Y coordinate of the window's location */
+    uint16_t     width;         /* Width of the window */
+    uint16_t     height;        /* Height of the window */
+    uint16_t     border_width;  /* Width of the window's border */
+} xcb_get_geometry_reply_t;
+
      +

      + XCB fill this structure with two functions: +

      + 
      +xcb_get_geometry_cookie_t  xcb_get_geometry       (xcb_connection_t         *c,
+                                                   xcb_drawable_t            drawable);
+xcb_get_geometry_reply_t  *xcb_get_geometry_reply (xcb_connection_t         *c,
+                                                   xcb_get_geometry_cookie_t cookie,
+                                                   xcb_generic_error_t     **e);
+
      +

      + You use them as follows: +

      + 
      +  xcb_connection_t         *c;
+  xcb_drawable_t            win;
+  xcb_get_geometry_reply_t *geom;
+
+  /* You initialize c and win */
+
+  geom = xcb_get_geometry_reply (c, xcb_get_geometry (c, win), NULL);
+
+  /* Do something with the fields of geom */
+
+  free (geom);
+
      +

      + Remark that you have to free the structure, as + xcb_get_geometry_reply_t allocates a + newly one. +

      +

      + One problem is that the returned location of the window is + relative to its parent window. This makes these coordinates + rather useless for any window manipulation functions, like + moving it on the screen. In order to overcome this problem, we + need to take a two-step operation. First, we find out the Id + of the parent window of our window. We then translate the + above relative coordinates to the screen coordinates. +

      +

      + To get the Id of the parent window, we need this structure: +

      + 
      +typedef struct {
+    uint8_t      response_type;
+    uint8_t      pad0;
+    uint16_t     sequence;
+    uint32_t     length;
+    xcb_window_t root;
+    xcb_window_t parent;       /* Id of the parent window */
+    uint16_t     children_len;
+    uint8_t      pad1[14];
+} xcb_query_tree_reply_t;
+
      +

      + To fill this structure, we use these two functions: +

      + 
      +xcb_query_tree_cookie_t xcb_query_tree       (xcb_connection_t        *c,
+                                              xcb_window_t             window);
+xcb_query_tree_reply_t *xcb_query_tree_reply (xcb_connection_t        *c,
+                                              xcb_query_tree_cookie_t  cookie,
+                                              xcb_generic_error_t    **e);
+
      +

      + The translated coordinates will be found in this structure: +

      + 
      +typedef struct {
+    uint8_t      response_type;
+    uint8_t      same_screen;
+    uint16_t     sequence;
+    uint32_t     length;
+    xcb_window_t child;
+    uint16_t     dst_x;        /* Translated x coordinate */
+    uint16_t     dst_y;        /* Translated y coordinate */
+} xcb_translate_coordinates_reply_t;
+
      +

      + As usual, we need two functions to fill this structure: +

      + 
      +xcb_translate_coordinates_cookie_t xcb_translate_coordinates       (xcb_connection_t                  *c,
+                                                                    xcb_window_t                       src_window,
+                                                                    xcb_window_t                       dst_window,
+                                                                    int16_t                            src_x,
+                                                                    int16_t                            src_y);
+xcb_translate_coordinates_reply_t *xcb_translate_coordinates_reply (xcb_connection_t                  *c,
+                                                                    xcb_translate_coordinates_cookie_t cookie,
+                                                                    xcb_generic_error_t              **e);
+
      +

      + We use them as follows: +

      + 
      +  xcb_connection_t                  *c;
+  xcb_drawable_t                     win;
+  xcb_get_geometry_reply_t          *geom;
+  xcb_query_tree_reply_t            *tree;
+  xcb_translate_coordinates_reply_t *trans;
+
+  /* You initialize c and win */
+
+  geom  = xcb_get_geometry_reply (c, xcb_get_geometry (c, win), NULL);
+  if (!geom)
+    return 0;
+
+  tree  = xcb_query_tree_reply (c, xcb_query_tree (c, win), NULL);
+  if (!tree)
+    return 0;
+
+  trans = xcb_translate_coordinates_reply (c,
+                                           xcb_translate_coordinates (c,
+                                                                      win,
+                                                                      tree->parent,
+                                                                      geom->x, geom->y),
+                                           NULL);
+  if (!trans)
+    return 0;
+
+  /* the translated coordinates are in trans->dst_x and trans->dst_y */
+
+  free (trans);
+  free (tree);
+  free (geom);
+
      +

      + Of course, as for geom, + tree and + trans have to be freed. +

      +

      + The work is a bit hard, but XCB is a very low-level library. +

      +

      + TODO: the utilization of these functions should be a + prog, which displays the coordinates of the window. +

      +

      + There is another structure that gives informations about our window: +

      + 
      +typedef struct {
+    uint8_t        response_type;
+    uint8_t        backing_store;
+    uint16_t       sequence;
+    uint32_t       length;
+    xcb_visualid_t visual;                /* Visual of the window */
+    uint16_t       _class;
+    uint8_t        bit_gravity;
+    uint8_t        win_gravity;
+    uint32_t       backing_planes;
+    uint32_t       backing_pixel;
+    uint8_t        save_under;
+    uint8_t        map_is_installed;
+    uint8_t        map_state;             /* Map state of the window */
+    uint8_t        override_redirect;
+    xcb_colormap_t colormap;              /* Colormap of the window */
+    uint32_t       all_event_masks;
+    uint32_t       your_event_mask;
+    uint16_t       do_not_propagate_mask;
+} xcb_get_window_attributes_reply_t;
+
      +

      + XCB supplies these two functions to fill it: +

      + 
      +xcb_get_window_attributes_cookie_t xcb_get_window_attributes       (xcb_connection_t                  *c,
+                                                                    xcb_window_t                       window);
+xcb_get_window_attributes_reply_t *xcb_get_window_attributes_reply (xcb_connection_t                  *c,
+                                                                    xcb_get_window_attributes_cookie_t cookie,
+                                                                    xcb_generic_error_t              **e);
+
      +

      + You use them as follows: +

      + 
      +  xcb_connection_t                  *c;
+  xcb_drawable_t                     win;
+  xcb_get_window_attributes_reply_t *attr;
+
+  /* You initialize c and win */
+
+  attr = xcb_get_window_attributes_reply (c, xcb_get_window_attributes (c, win), NULL);
+
+  if (!attr)
+    return 0;
+
+  /* Do something with the fields of attr */
+
+  free (attr);
+
      +

      + As for geom, + attr has to be freed. +

      +
    +
  14. Using colors to paint the rainbow +

    + Up until now, all our painting operation were done using black + and white. We will (finally) see now how to draw using colors. +

    +
      +
    1. Color maps +

      + In the beginning, there were not enough colors. Screen + controllers could only support a limited number of colors + simultaneously (initially 2, then 4, 16 and 256). Because of + this, an application could not just ask to draw in a "light + purple-red" color, and expect that color to be available. Each + application allocated the colors it needed, and when all the + color entries (4, 16, 256 colors) were in use, the next color + allocation would fail. +

      +

      + Thus, the notion of "a color map" was introduced. A color map + is a table whose size is the same as the number of + simultaneous colors a given screen controller. Each entry + contained the RGB (Red, Green and Blue) values of a different + color (all colors can be drawn using some combination of red, + green and blue). When an application wants to draw on the + screen, it does not specify which color to use. Rather, it + specifies which color entry of some color map to be used + during this drawing. Change the value in this color map entry + and the drawing will use a different color. +

      +

      + In order to be able to draw using colors that got something to + do with what the programmer intended, color map allocation + functions are supplied. You could ask to allocate entry for a + color with a set of RGB values. If one already existed, you + would get its index in the table. If none existed, and the + table was not full, a new cell would be allocated to contain + the given RGB values, and its index returned. If the table was + full, the procedure would fail. You could then ask to get a + color map entry with a color that is closest to the one you + were asking for. This would mean that the actual drawing on + the screen would be done using colors similar to what you + wanted, but not the same. +

      +

      + On today's more modern screens where one runs an X server with + support for 16 million colors, this limitation looks a little + silly, but remember that there are still older computers with + older graphics cards out there. Using color map, support for + these screen becomes transparent to you. On a display + supporting 16 million colors, any color entry allocation + request would succeed. On a display supporting a limited + number of colors, some color allocation requests would return + similar colors. It won't look as good, but your application + would still work. +

      +
    2. Allocating and freeing Color Maps +

      + When you draw using XCB, you can choose to use the standard + color map of the screen your window is displayed on, or you + can allocate a new color map and apply it to a window. In the + latter case, each time the mouse moves onto your window, the + screen color map will be replaced by your window's color map, + and you'll see all the other windows on screen change their + colors into something quite bizarre. In fact, this is the + effect you get with X applications that use the "-install" + command line option. +

      +

      + In XCB, a color map is (as often in X) an Id: +

      + 
      +typedef uint32_t xcb_colormap_t;
+
      +

      + In order to access the screen's default color map, you just + have to retrieve the default_colormap + field of the xcb_screen_t structure + (see Section + Checking basic information about a connection): +

      + 
      +#include <stdio.h>
+
+#include <xcb/xcb.h>
+
+int
+main ()
+{
+  xcb_connection_t *c;
+  xcb_screen_t     *screen;
+  xcb_colormap_t    colormap;
+
+  /* Open the connection to the X server and get the first screen */
+  c = xcb_connect (NULL, NULL);
+  screen = xcb_setup_roots_iterator (xcb_get_setup (c)).data;
+
+  colormap = screen->default_colormap;
+
+  return 0;
+}
+
      +

      + This will return the color map used by default on the first + screen (again, remember that an X server may support several + different screens, each of which might have its own resources). +

      +

      + The other option, that of allocating a new colormap, works as + follows. We first ask the X server to give an Id to our color + map, with this function: +

      + 
      +xcb_colormap_t xcb_generate_id (xcb_connection_t *c);
+
      +

      + Then, we create the color map with +

      + 
      +xcb_void_cookie_t xcb_create_colormap (xcb_connection_t *c,       /* Pointer to the xcb_connection_t structure */
+                                       uint8_t           alloc,   /* Colormap entries to be allocated (AllocNone or AllocAll) */
+                                       xcb_colormap_t    mid,     /* Id of the color map */
+                                       xcb_window_t      window,  /* Window on whose screen the colormap will be created */
+                                       xcb_visualid_t    visual); /* Id of the visual supported by the screen */
+
      +

      + Here is an example of creation of a new color map: +

      + 
      +#include <xcb/xcb.h>
+
+int
+main ()
+{
+  xcb_connection_t *c;
+  xcb_screen_t     *screen;
+  xcb_window_t      win;
+  xcb_colormap_t    cmap
+
+  /* Open the connection to the X server and get the first screen */
+  c = xcb_connect (NULL, NULL);
+  screen = xcb_setup_roots_iterator (xcb_get_setup (c)).data;
+
+  /* We create the window win here*/
+
+  cmap = xcb_generate_id (c);
+  xcb_create_colormap (c, XCB_COLORMAP_ALLOC_NONE, cmap, win, screen->root_visual);
+
+  return 0;
+}
+
      +

      + Note that the window parameter is only used to allow the X + server to create the color map for the given screen. We can + then use this color map for any window drawn on the same screen. +

      +

      + To free a color map, it suffices to use this function: +

      + 
      +xcb_void_cookie_t xcb_free_colormap (xcb_connection_t *c,   /* The connection */
+                                     xcb_colormap_t cmap);  /* The color map */
+
      +
      +
      + Comparison Xlib/XCB +
      +
      +

      +
      +
    3. Allocating and freeing a color entry +

      + Once we got access to some color map, we can start allocating + colors. The informations related to a color are stored in the + following structure: +

      + 
      +typedef struct {
+    uint8_t  response_type;
+    uint8_t  pad0;
+    uint16_t sequence;
+    uint32_t length;
+    uint16_t red;          /* The red component   */
+    uint16_t green;        /* The green component */
+    uint16_t blue;         /* The blue component  */
+    uint8_t  pad1[2];
+    uint32_t pixel;        /* The entry in the color map, supplied by the X server */
+} xcb_alloc_color_reply_t;
+
      +

      + XCB supplies these two functions to fill it: +

      + 
      +xcb_alloc_color_cookie_t xcb_alloc_color       (xcb_connection_t        *c,
+                                                xcb_colormap_t           cmap,
+                                                uint16_t                 red,
+                                                uint16_t                 green,
+                                                uint16_t                 blue);
+xcb_alloc_color_reply_t *xcb_alloc_color_reply (xcb_connection_t        *c,
+                                                xcb_alloc_color_cookie_t cookie,
+                                                xcb_generic_error_t    **e);
+
      +

      + The fuction xcb_alloc_color() takes the + 3 RGB components as parameters (red, green and blue). Here is an + example of using these functions: +

      + 
      +#include <malloc.h>
+
+#include <xcb/xcb.h>
+
+int
+main ()
+{
+  xcb_connection_t        *c;
+  xcb_screen_t            *screen;
+  xcb_window_t             win;
+  xcb_colormap_t           cmap;
+  xcb_alloc_color_reply_t *rep;
+
+  /* Open the connection to the X server and get the first screen */
+  c = xcb_connect (NULL, NULL);
+  screen = xcb_setup_roots_iterator (xcb_get_setup (c)).data;
+
+  /* We create the window win here*/
+
+  cmap = xcb_generate_id (c);
+  xcb_create_colormap (c, XCB_COLORMAP_ALLOC_NONE, cmap, win, screen->root_visual);
+
+  rep = xcb_alloc_color_reply (c, xcb_alloc_color (c, cmap, 65535, 0, 0), NULL);
+
+  if (!rep)
+    return 0;
+
+  /* Do something with r->pixel or the components */
+
+  free (rep);
+
+  return 0;
+}
+
      +

      + As xcb_alloc_color_reply() allocates + memory, you have to free rep. +

      +

    +
  15. X Bitmaps and Pixmaps +

    + One thing many so-called "Multi-Media" applications need to do, + is display images. In the X world, this is done using bitmaps + and pixmaps. We have already seen some usage of them when + setting an icon for our application. Lets study them further, + and see how to draw these images inside a window, along side the + simple graphics and text we have seen so far. +

    +

    + One thing to note before delving further, is that XCB (nor Xlib) + supplies no means of manipulating popular image formats, such as + gif, png, jpeg or tiff. It is up to the programmer (or to higher + level graphics libraries) to translate these image formats into + formats that the X server is familiar with (x bitmaps and x + pixmaps). +

    +
      +
    1. What is a X Bitmap? An X Pixmap? +

      + An X bitmap is a two-color image stored in a format specific + to the X window system. When stored in a file, the bitmap data + looks like a C source file. It contains variables defining the + width and the height of the bitmap, an array containing the + bit values of the bitmap (the size of the array is + (width+7)/8*height and the bit and byte order are LSB), and + an optional hot-spot location (that will + be explained later, when discussing mouse cursors). +

      +

      + An X pixmap is a format used to stored images in the memory of + an X server. This format can store both black and white images + (such as x bitmaps) as well as color images. It is the only + image format supported by the X protocol, and any image to be + drawn on screen, should be first translated into this format. +

      +

      + In actuality, an X pixmap can be thought of as a window that + does not appear on the screen. Many graphics operations that + work on windows, will also work on pixmaps. Indeed, the type + of X pixmap in XCB is an Id like a window: +

      + 
      +typedef uint32_t xcb_pixmap_t;
+
      +

      + Like Xlib, there is no difference between a Drawable, a Window + or a Pixmap: +

      + 
      +typedef uint32_t xcb_drawable_t;
+
      +

      + in order to avoid confusion between a window and a pixmap. The + operations that will work the same on a window or a pixmap + will require a xcb_drawable_t +

      +
      +

      + Remark: In Xlib, there is no specific difference between a + Drawable, a + Pixmap or a + Window: all are 32 bit long + integer. XCB wraps all these different IDs in structures to + provide some measure of type-safety. +

      +
      +
    2. Creating a pixmap +

      + Sometimes we want to create an un-initialized pixmap, so we + can later draw into it. This is useful for image drawing + programs (creating a new empty canvas will cause the creation + of a new pixmap on which the drawing can be stored). It is + also useful when reading various image formats: we load the + image data into memory, create a pixmap on the server, and + then draw the decoded image data onto that pixmap. +

      +

      + To create a new pixmap, we first ask the X server to give an + Id to our pixmap, with this function: +

      + 
      +xcb_pixmap_t xcb_generate_id (xcb_connection_t *c);
+
      +

      + Then, XCB supplies the following function to create new pixmaps: +

      + 
      +xcb_void_cookie_t xcb_create_pixmap (xcb_connection_t *c,         /* Pointer to the xcb_connection_t structure */
+                                     uint8_t           depth,     /* Depth of the screen */
+                                     xcb_pixmap_t      pid,       /* Id of the pixmap */
+                                     xcb_drawable_t    drawable,
+                                     uint16_t          width,     /* Width of the window (in pixels) */
+                                     uint16_t          height);   /* Height of the window (in pixels) */
+
      +

      + TODO: Explain the drawable parameter, and give an + example (like xpoints.c) +

      +
    3. Drawing a pixmap in a window +

      + Once we got a handle to a pixmap, we can draw it on some + window, using the following function: +

      + 
      +xcb_void_cookie_t xcb_copy_area (xcb_connection_t *c,             /* Pointer to the xcb_connection_t structure */
+                                 xcb_drawable_t    src_drawable,  /* The Drawable we want to paste */
+                                 xcb_drawable_t    dst_drawable,  /* The Drawable on which we copy the previous Drawable */
+                                 xcb_gcontext_t    gc,            /* A Graphic Context */
+                                 int16_t           src_x,         /* Top left x coordinate of the region we want to copy */
+                                 int16_t           src_y,         /* Top left y coordinate of the region we want to copy */
+                                 int16_t           dst_x,         /* Top left x coordinate of the region where we want to copy */
+                                 int16_t           dst_y,         /* Top left y coordinate of the region where we want to copy */
+                                 uint16_t          width,         /* Width of the region we want to copy */
+                                 uint16_t          height);       /* Height of the region we want to copy */
+
      +

      + As you can see, we could copy the whole pixmap, as well as + only a given rectangle of the pixmap. This is useful to + optimize the drawing speed: we could copy only what we have + modified in the pixmap. +

      +

      + One important note should be made: it is possible to + create pixmaps with different depths on the same screen. When + we perform copy operations (a pixmap onto a window, etc), we + should make sure that both source and target have the same + depth. If they have a different depth, the operation would + fail. The exception to this is if we copy a specific bit plane + of the source pixmap using the + xcb_copy_plane_t function. In such an + event, we can copy a specific plane to the target window (in + actuality, setting a specific bit in the color of each pixel + copied). This can be used to generate strange graphic effects + in a window, but that is beyond the scope of this tutorial. +

      +
    4. Freeing a pixmap +

      + Finally, when we are done using a given pixmap, we should free + it, in order to free resources of the X server. This is done + using this function: +

      + 
      +xcb_void_cookie_t xcb_free_pixmap (xcb_connection_t *c,        /* Pointer to the xcb_connection_t structure */
+                                   xcb_pixmap_t      pixmap);  /* A given pixmap */
+
      +

      + Of course, after having freed it, we must not try accessing + the pixmap again. +

      +

      + TODO: Give an example, or a link to xpoints.c +

      +
    +
  16. Messing with the mouse cursor +

    + It it possible to modify the shape of the mouse pointer (also + called the X pointer) when in certain states, as we often see in + programs. For example, a busy application would often display + the hourglass cursor over its main window, to give the user a visual + hint that they should wait. Let's see how we can change the mouse + cursor of our windows. +

    +
      +
    1. Creating and destroying a mouse cursor +

      + There are two methods for creating cursors. One of them is by + using a set of predefined cursors, that are supplied by the X + server, the other is by using a user-supplied bitmap. +

      +

      + In the first method, we use a special font named "cursor", and + the function xcb_create_glyph_cursor: +

      + 
      +xcb_void_cookie_t xcb_create_glyph_cursor (xcb_connection_t *c,
+                                           xcb_cursor_t      cid,
+                                           xcb_font_t        source_font, /* font for the source glyph */
+                                           xcb_font_t        mask_font,   /* font for the mask glyph or XCB_NONE */
+                                           uint16_t          source_char, /* character glyph for the source */
+                                           uint16_t          mask_char,   /* character glyph for the mask */
+                                           uint16_t          fore_red,    /* red value for the foreground of the source */
+                                           uint16_t          fore_green,  /* green value for the foreground of the source */
+                                           uint16_t          fore_blue,   /* blue value for the foreground of the source */
+                                           uint16_t          back_red,    /* red value for the background of the source */
+                                           uint16_t          back_green,  /* green value for the background of the source */
+                                           uint16_t          back_blue)   /* blue value for the background of the source */
+
      +

      + TODO: Describe source_char + and mask_char, for example by giving + an example on how to get the values. There is a list there: + X Font Cursors +

      +

      + So we first open that font (see Loading a Font) + and create the new cursor. As for every X resource, we have to + ask for an X id with xcb_generate_id + first: +

      + 
      +xcb_font_t           font;
+xcb_cursor_t         cursor;
+
+/* The connection is set */
+
+font = xcb_generate_id (conn);
+xcb_open_font (conn, font, strlen ("cursor"), "cursor");
+
+cursor = xcb_generate_id (conn);
+xcb_create_glyph_cursor (conn, cursor, font, font,
+                         58, 58 + 1,
+                         0, 0, 0,
+                         0, 0, 0);
+
      +

      + We have created the cursor "right hand" by specifying 58 to + the source_font argument and 58 + 1 + to the mask_font. +

      +

      + The cursor is destroyed by using the function +

      + 
      +xcb_void_cookie_t xcb_free_cursor (xcb_connection_t *c,
+                                   xcb_cursor_t      cursor);
+
      +

      + In the second method, we create a new cursor by using a pair + of pixmaps, with depth of one (that is, two colors + pixmaps). One pixmap defines the shape of the cursor, while + the other works as a mask, specifying which pixels of the + cursor will be actually drawn. The rest of the pixels will be + transparent. +

      +

      + TODO: give an example. +

      +
    2. Setting a window's mouse cursor +

      + Once the cursor is created, we can modify the cursor of our + window by using xcb_change_window_attributes + and using the XCB_CWCURSOR attribute: +

      + 
      +uint32_t mask;
+uint32_t value_list;
+
+/* The connection and window are set */
+/* The cursor is already created */
+
+mask = XCB_CWCURSOR;
+value_list = cursor;
+xcb_change_window_attributes (conn, window, mask, &value_list);
+
      +

      + Of course, the cursor and the font must be freed. +

      +
    3. Complete example +

      + The following example displays a window with a + button. When entering the window, the window cursor is changed + to an arrow. When clicking once on the button, the cursor is + changed to a hand. When clicking again on the button, the + cursor window gets back to the arrow. The Esc key exits the + application. +

  17. Translation of basic Xlib functions and macros +

    + The problem when you want to port an Xlib program to XCB is that + you don't know if the Xlib function that you want to "translate" + is a X Window one or an Xlib macro. In that section, we describe + a way to translate the usual functions or macros that Xlib + provides. It's usually just a member of a structure. +

    +
      +
    1. Members of the Display structure +

      + In this section, we look at how to translate the macros that + return some members of the Display + structure. They are obtained by using a function that requires a + xcb_connection_t * or a member of the + xcb_setup_t structure + (via the function xcb_get_setup), or + a function that requires that structure. +

      +
        +
      1. ConnectionNumber +

        + This number is the file descriptor that connects the client + to the server. You just have to use that function: +

        + 
        +int xcb_get_file_descriptor (xcb_connection_t *c);
+
        +
      2. DefaultScreen +

        + That number is not stored by XCB. It is returned in the + second parameter of the function xcb_connect. + Hence, you have to store it yourself if you want to use + it. Then, to get the xcb_screen_t + structure, you have to iterate on the screens. + The equivalent function of the Xlib's + ScreenOfDisplay function can be + found below. This is also provided in the + xcb_aux_t library as xcb_aux_get_screen(). OK, here is the + small piece of code to get that number: +

        + 
        +xcb_connection_t *c;
+int               screen_default_nbr;
+
+/* you pass the name of the display you want to xcb_connect_t */
+
+c = xcb_connect (display_name, &screen_default_nbr);
+
+/* screen_default_nbr contains now the number of the default screen */
+
        +
      3. QLength +

        + Not documented yet. +

        +

        + However, this points out a basic difference in philosophy between + Xlib and XCB. Xlib has several functions for filtering and + manipulating the incoming and outgoing X message queues. XCB + wishes to hide this as much as possible from the user, which + allows for more freedom in implementation strategies. +

        +
      4. ScreenCount +

        + You get the count of screens with the functions + xcb_get_setup + and + xcb_setup_roots_iterator + (if you need to iterate): +

        + 
        +xcb_connection_t *c;
+int               screen_count;
+
+/* you init the connection */
+
+screen_count = xcb_setup_roots_iterator (xcb_get_setup (c)).rem;
+
+/* screen_count contains now the count of screens */
+
        +

        + If you don't want to iterate over the screens, a better way + to get that number is to use + xcb_setup_roots_length_t: +

        + 
        +xcb_connection_t *c;
+int               screen_count;
+
+/* you init the connection */
+
+screen_count = xcb_setup_roots_length (xcb_get_setup (c));
+
+/* screen_count contains now the count of screens */
+
        +
      5. ServerVendor +

        + You get the name of the vendor of the server hardware with + the functions xcb_get_setup + and + xcb_setup_vendor. Beware + that, unlike Xlib, the string returned by XCB is not + necessarily null-terminaled: +

        + 
        +xcb_connection_t *c;
+char             *vendor = NULL;
+int               length;
+
+/* you init the connection */
+length = xcb_setup_vendor_length (xcb_get_setup (c));
+vendor = (char *)malloc (length + 1);
+if (vendor)
+memcpy (vendor, xcb_setup_vendor (xcb_get_setup (c)), length);
+vendor[length] = '\0';
+
+/* vendor contains now the name of the vendor. Must be freed when not used anymore */
+
        +
      6. ProtocolVersion +

        + You get the major version of the protocol in the + xcb_setup_t + structure, with the function xcb_get_setup: +

        + 
        +xcb_connection_t *c;
+uint16_t          protocol_major_version;
+
+/* you init the connection */
+
+protocol_major_version = xcb_get_setup (c)->protocol_major_version;
+
+/* protocol_major_version contains now the major version of the protocol */
+
        +
      7. ProtocolRevision +

        + You get the minor version of the protocol in the + xcb_setup_t + structure, with the function xcb_get_setup: +

        + 
        +xcb_connection_t *c;
+uint16_t          protocol_minor_version;
+
+/* you init the connection */
+
+protocol_minor_version = xcb_get_setup (c)->protocol_minor_version;
+
+/* protocol_minor_version contains now the minor version of the protocol */
+
        +
      8. VendorRelease +

        + You get the number of the release of the server hardware in the + xcb_setup_t + structure, with the function xcb_get_setup: +

        + 
        +xcb_connection_t *c;
+uint32_t          release_number;
+
+/* you init the connection */
+
+release_number = xcb_get_setup (c)->release_number;
+
+/* release_number contains now the number of the release of the server hardware */
+
        +
      9. DisplayString +

        + The name of the display is not stored in XCB. You have to + store it by yourself. +

        +
      10. BitmapUnit +

        + You get the bitmap scanline unit in the + xcb_setup_t + structure, with the function xcb_get_setup: +

        + 
        +xcb_connection_t *c;
+uint8_t           bitmap_format_scanline_unit;
+
+/* you init the connection */
+
+bitmap_format_scanline_unit = xcb_get_setup (c)->bitmap_format_scanline_unit;
+
+/* bitmap_format_scanline_unit contains now the bitmap scanline unit */
+
        +
      11. BitmapBitOrder +

        + You get the bitmap bit order in the + xcb_setup_t + structure, with the function xcb_get_setup: +

        + 
        +xcb_connection_t *c;
+uint8_t           bitmap_format_bit_order;
+
+/* you init the connection */
+
+bitmap_format_bit_order = xcb_get_setup (c)->bitmap_format_bit_order;
+
+/* bitmap_format_bit_order contains now the bitmap bit order */
+
        +
      12. BitmapPad +

        + You get the bitmap scanline pad in the + xcb_setup_t + structure, with the function xcb_get_setup: +

        + 
        +xcb_connection_t *c;
+uint8_t           bitmap_format_scanline_pad;
+
+/* you init the connection */
+
+bitmap_format_scanline_pad = xcb_get_setup (c)->bitmap_format_scanline_pad;
+
+/* bitmap_format_scanline_pad contains now the bitmap scanline pad */
+
        +
      13. ImageByteOrder +

        + You get the image byte order in the + xcb_setup_t + structure, with the function xcb_get_setup: +

        + 
        +xcb_connection_t *c;
+uint8_t           image_byte_order;
+
+/* you init the connection */
+
+image_byte_order = xcb_get_setup (c)->image_byte_order;
+
+/* image_byte_order contains now the image byte order */
+
        +
      +
    2. ScreenOfDisplay related functions +

      + in Xlib, ScreenOfDisplay returns a + Screen structure that contains + several characteristics of your screen. XCB has a similar + structure (xcb_screen_t), + but the way to obtain it is a bit different. With + Xlib, you just provide the number of the screen and you grab it + from an array. With XCB, you iterate over all the screens to + obtain the one you want. The complexity of this operation is + O(n). So the best is to store this structure if you use + it often. See screen_of_display just below. +

      +

      + Xlib provides generally two functions to obtain the characteristics + related to the screen. One with the display and the number of + the screen, which calls ScreenOfDisplay, + and the other that uses the Screen structure. + This might be a bit confusing. As mentioned above, with XCB, it + is better to store the xcb_screen_t + structure. Then, you have to read the members of this + structure. That's why the Xlib functions are put by pairs (or + more) as, with XCB, you will use the same code. +

      +
        +
      1. ScreenOfDisplay +

        + This function returns the Xlib Screen + structure. With XCB, you iterate over all the screens and + once you get the one you want, you return it: +

        + 
        
+xcb_screen_t *screen_of_display (xcb_connection_t *c,
+                                 int               screen)
+{
+  xcb_screen_iterator_t iter;
+
+  iter = xcb_setup_roots_iterator (xcb_get_setup (c));
+  for (; iter.rem; --screen, xcb_screen_next (&iter))
+    if (screen == 0)
+      return iter.data;
+
+  return NULL;
+}
+
        +

        + As mentioned above, you might want to store the value + returned by this function. +

        +

        + All the functions below will use the result of that + function, as they just grab a specific member of the + xcb_screen_t structure. +

        +
      2. DefaultScreenOfDisplay +

        + It is the default screen that you obtain when you connect to + the X server. It suffices to call the screen_of_display + function above with the connection and the number of the + default screen. +

        + 
        +xcb_connection_t *c;
+int               screen_default_nbr;
+xcb_screen_t     *default_screen;  /* the returned default screen */
+
+/* you pass the name of the display you want to xcb_connect_t */
+
+c = xcb_connect (display_name, &screen_default_nbr);
+default_screen = screen_of_display (c, screen_default_nbr);
+
+/* default_screen contains now the default root window, or a NULL window if no screen is found */
+
        +
      3. RootWindow / RootWindowOfScreen +
        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+xcb_window_t      root_window = { 0 };  /* the returned window */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen)
+  root_window = screen->root;
+
+/* root_window contains now the root window, or a NULL window if no screen is found */
+
        +
      4. DefaultRootWindow +

        + It is the root window of the default screen. So, you call + ScreenOfDisplay with the + default screen number and you get the + root window as above: +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_default_nbr;
+xcb_window_t      root_window = { 0 };  /* the returned root window */
+
+/* you pass the name of the display you want to xcb_connect_t */
+
+c = xcb_connect (display_name, &screen_default_nbr);
+screen = screen_of_display (c, screen_default_nbr);
+if (screen)
+  root_window = screen->root;
+
+/* root_window contains now the default root window, or a NULL window if no screen is found */
+
        +
      5. DefaultVisual / DefaultVisualOfScreen +

        + While a Visual is, in Xlib, a structure, in XCB, there are + two types: xcb_visualid_t, which is + the Id of the visual, and xcb_visualtype_t, + which corresponds to the Xlib Visual. To get the Id of the + visual of a screen, just get the + root_visual + member of a xcb_screen_t: +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+xcb_visualid_t    root_visual = { 0 };    /* the returned visual Id */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen)
+  root_visual = screen->root_visual;
+
+/* root_visual contains now the value of the Id of the visual, or a NULL visual if no screen is found */
+
        +

        + To get the xcb_visualtype_t + structure, it's a bit less easy. You have to get the + xcb_screen_t structure that you want, + get its root_visual member, + then iterate over the xcb_depth_ts + and the xcb_visualtype_ts, and compare + the xcb_visualid_t of these xcb_visualtype_ts: + with root_visual: +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+xcb_visualid_t    root_visual = { 0 };
+xcb_visualtype_t  *visual_type = NULL;    /* the returned visual type */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen) {
+  xcb_depth_iterator_t depth_iter;
+
+  depth_iter = xcb_screen_allowed_depths_iterator (screen);
+  for (; depth_iter.rem; xcb_depth_next (&depth_iter)) {
+    xcb_visualtype_iterator_t visual_iter;
+
+    visual_iter = xcb_depth_visuals_iterator (depth_iter.data);
+    for (; visual_iter.rem; xcb_visualtype_next (&visual_iter)) {
+      if (screen->root_visual == visual_iter.data->visual_id) {
+        visual_type = visual_iter.data;
+        break;
+      }
+    }
+  }
+}
+
+/* visual_type contains now the visual structure, or a NULL visual structure if no screen is found */
+
        +
      6. DefaultGC / DefaultGCOfScreen +

        + This default Graphic Context is just a newly created Graphic + Context, associated to the root window of a + xcb_screen_t, + using the black white pixels of that screen: +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+xcb_gcontext_t    gc = { 0 };    /* the returned default graphic context */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen) {
+  xcb_drawable_t draw;
+  uint32_t       mask;
+  uint32_t       values[2];
+
+  gc = xcb_generate_id (c);
+  draw = screen->root;
+  mask = XCB_GC_FOREGROUND | XCB_GC_BACKGROUND;
+  values[0] = screen->black_pixel;
+  values[1] = screen->white_pixel;
+  xcb_create_gc (c, gc, draw, mask, values);
+}
+
+/* gc contains now the default graphic context */
+
        +
      7. BlackPixel / BlackPixelOfScreen +

        + It is the Id of the black pixel, which is in the structure + of an xcb_screen_t. +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+uint32_t          black_pixel = 0;    /* the returned black pixel */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen)
+  black_pixel = screen->black_pixel;
+
+/* black_pixel contains now the value of the black pixel, or 0 if no screen is found */
+
        +
      8. WhitePixel / WhitePixelOfScreen +

        + It is the Id of the white pixel, which is in the structure + of an xcb_screen_t. +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+uint32_t          white_pixel = 0;    /* the returned white pixel */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen)
+  white_pixel = screen->white_pixel;
+
+/* white_pixel contains now the value of the white pixel, or 0 if no screen is found */
+
        +
      9. DisplayWidth / WidthOfScreen +

        + It is the width in pixels of the screen that you want, and + which is in the structure of the corresponding + xcb_screen_t. +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+uint32_t          width_in_pixels = 0;    /* the returned width in pixels */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen)
+  width_in_pixels = screen->width_in_pixels;
+
+/* width_in_pixels contains now the width in pixels, or 0 if no screen is found */
+
        +
      10. DisplayHeight / HeightOfScreen +

        + It is the height in pixels of the screen that you want, and + which is in the structure of the corresponding + xcb_screen_t. +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+uint32_t          height_in_pixels = 0;    /* the returned height in pixels */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen)
+  height_in_pixels = screen->height_in_pixels;
+
+/* height_in_pixels contains now the height in pixels, or 0 if no screen is found */
+
        +
      11. DisplayWidthMM / WidthMMOfScreen +

        + It is the width in millimeters of the screen that you want, and + which is in the structure of the corresponding + xcb_screen_t. +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+uint32_t          width_in_millimeters = 0;    /* the returned width in millimeters */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen)
+  width_in_millimeters = screen->width_in_millimeters;
+
+/* width_in_millimeters contains now the width in millimeters, or 0 if no screen is found */
+
        +
      12. DisplayHeightMM / HeightMMOfScreen +

        + It is the height in millimeters of the screen that you want, and + which is in the structure of the corresponding + xcb_screen_t. +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+uint32_t          height_in_millimeters = 0;    /* the returned height in millimeters */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen)
+  height_in_millimeters = screen->height_in_millimeters;
+
+/* height_in_millimeters contains now the height in millimeters, or 0 if no screen is found */
+
        +
      13. DisplayPlanes / DefaultDepth / DefaultDepthOfScreen / PlanesOfScreen +

        + It is the depth (in bits) of the root window of the + screen. You get it from the xcb_screen_t structure. +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+uint8_t           root_depth = 0;  /* the returned depth of the root window */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen)
+  root_depth = screen->root_depth;
+
+/* root_depth contains now the depth of the root window, or 0 if no screen is found */
+
        +
      14. DefaultColormap / DefaultColormapOfScreen +

        + This is the default colormap of the screen (and not the + (default) colormap of the default screen !). As usual, you + get it from the xcb_screen_t structure: +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+xcb_colormap_t    default_colormap = { 0 };  /* the returned default colormap */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen)
+  default_colormap = screen->default_colormap;
+
+/* default_colormap contains now the default colormap, or a NULL colormap if no screen is found */
+
        +
      15. MinCmapsOfScreen +

        + You get the minimum installed colormaps in the xcb_screen_t structure: +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+uint16_t          min_installed_maps = 0;  /* the returned minimum installed colormaps */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen)
+  min_installed_maps = screen->min_installed_maps;
+
+/* min_installed_maps contains now the minimum installed colormaps, or 0 if no screen is found */
+
        +
      16. MaxCmapsOfScreen +

        + You get the maximum installed colormaps in the xcb_screen_t structure: +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+uint16_t          max_installed_maps = 0;  /* the returned maximum installed colormaps */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen)
+  max_installed_maps = screen->max_installed_maps;
+
+/* max_installed_maps contains now the maximum installed colormaps, or 0 if no screen is found */
+
        +
      17. DoesSaveUnders +

        + You know if save_unders is set, + by looking in the xcb_screen_t structure: +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+uint8_t           save_unders = 0;  /* the returned value of save_unders */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen)
+  save_unders = screen->save_unders;
+
+/* save_unders contains now the value of save_unders, or FALSE if no screen is found */
+
        +
      18. DoesBackingStore +

        + You know the value of backing_stores, + by looking in the xcb_screen_t structure: +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+uint8_t           backing_stores = 0;  /* the returned value of backing_stores */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen)
+  backing_stores = screen->backing_stores;
+
+/* backing_stores contains now the value of backing_stores, or FALSE if no screen is found */
+
        +
      19. EventMaskOfScreen +

        + To get the current input masks, + you look in the xcb_screen_t structure: +

        + 
        +xcb_connection_t *c;
+xcb_screen_t     *screen;
+int               screen_nbr;
+uint32_t          current_input_masks = 0;  /* the returned value of current input masks */
+
+/* you init the connection and screen_nbr */
+
+screen = screen_of_display (c, screen_nbr);
+if (screen)
+  current_input_masks = screen->current_input_masks;
+
+/* current_input_masks contains now the value of the current input masks, or FALSE if no screen is found */
+
        +
      +
    3. Miscellaneous macros +
        +
      1. DisplayOfScreen +

        + in Xlib, the Screen structure + stores its associated Display + structure. This is not the case in the X Window protocol, + hence, it's also not the case in XCB. So you have to store + it by yourself. +

        +
      2. DisplayCells / CellsOfScreen +

        + To get the colormap entries, + you look in the xcb_visualtype_t + structure, that you grab like here: +

        + 
        +xcb_connection_t *c;
+xcb_visualtype_t *visual_type;
+uint16_t          colormap_entries = 0;  /* the returned value of the colormap entries */
+
+/* you init the connection and visual_type */
+
+if (visual_type)
+  colormap_entries = visual_type->colormap_entries;
+
+/* colormap_entries contains now the value of the colormap entries, or FALSE if no screen is found */
+

The issues +mentioned here are at most partly resolved. + +1. The are several XxxDoodad structures defined in xkb.xml. They are used + in a few lists, but in a rather special way: + The struct "CommonDoodad" is supposed to be a rather generic data type, + combining the most basic Doodad fields that are common in all these structures. + All Doodads are encapsulated in a union type simply called "Doodad". + Now this union is used in subsequent list definitions, aiming at a kind of + 'polymorphism': From inspection of the protocol and Xlib, the Doodads are to + be discriminated based on their type field. + However the special meaning of the type field is not encoded in the protocol. + Furthermore the TextDoodad and the LogoDoodad are variable size types due to + some fields of type CountedString16, thereby turning the union into a + possibly variable size type as well. + However, for lists with variable size elements, special sizeof functions are + required. These cannot be autogenerated as it cannot be referred which + Doodad type to use for the union. + Therefore, the Doodad type structures are unsupported at the moment. + +2. There are still some bugs in xkb.xml: Either certain fields are missing + that are required by the protocol, or Xlib simply has another understanding + of the protocol. + +3. The interface for accessors should be reviewed. + +4. Currently some bitcases carry 'name' attributes. These could be avoided if + the data within would consist of a singe struct field only. + +5. switch could get a 'fixed_size' attribute, so when rewriting valueparam to switch, + an uint32_t * pointer could be used instead of void *. + +6. The automatic inclusion of padding requires some complicated coding in the + generator. This is errorprone and could be avoided if all padding is explicitly + given in the protocol definition. For variable size fields that require padding, + the pad tag could get a 'fieldref' attribute. That way padding could be handled + a lot easier in the autogenerator. \ No newline at end of file diff --git a/m4/libtool.m4 b/m4/libtool.m4 new file mode 100644 index 0000000..e67ed69 --- /dev/null +++ b/m4/libtool.m4 @@ -0,0 +1,8387 @@ +# libtool.m4 - Configure libtool for the host system. -*-Autoconf-*- +# +# Copyright (C) 1996-2001, 2003-2015 Free Software Foundation, Inc. +# Written by Gordon Matzigkeit, 1996 +# +# This file is free software; the Free Software Foundation gives +# unlimited permission to copy and/or distribute it, with or without +# modifications, as long as this notice is preserved. + +m4_define([_LT_COPYING], [dnl +# Copyright (C) 2014 Free Software Foundation, Inc. +# This is free software; see the source for copying conditions.

\- manpage examples +.SH DESCRIPTION +Many of the XCB manpages contain example code. These examples intend to explain +how to use one particular part of XCB. They almost never represent a standalone +(or even useful) program - X11 programs are relatively involved and +thus beyond the scope of a manpage example. + +.SH ENVIRONMENT + +Every example assumes you have an \fIxcb_connection\fP and possibly other +variables at hand. For illustrating how \fIxcb_get_property\fP works, you need +the window of which you want to get the property, for example. To make it clear +that these variables are your responsibility, these examples consist of a +single function which takes the necessary variables as parameters. + +.SH FLUSHING + +Flushing means calling \fIxcb_flush\fP to clear the XCB-internal write buffer +and send all pending requests to the X11 server. You don't explicitly need to +flush before using a reply function (like \fIxcb_query_pointer_reply\fP), but +you do need to flush before entering the event loop of your program. + +There are only two cases when XCB flushes by itself. The first case is when +its write buffer becomes full, the second case is when you are asking for +the reply of a request which wasn't flushed out yet (like +\fIxcb_query_pointer_reply\fP). This last point also includes +xcb_request_check(). Please note that waiting for an event does \fBNOT\fP +flush. + +Examples generally include the \fIxcb_flush\fP call where appropriate (for +example after setting a property). Therefore, including these functions and +calling them in your application should just work. However, you might get +better results when flushing outside of the function, depending on the +architecture of your program. + +.SH COMPILATION + +If an example does not compile (without warnings) when using \fI-std=c99\fP, +that is considered a documentation bug. Similarly, not handling errors or +leaking memory is also considered a documentation bug. Please inform us about +it on xcb@lists.freedesktop.org. + +.SH CODING STYLE + +Every example uses 4 spaces for indentation. + +Comments are in asterisks, like /* this */. + +No line is longer than 80 characters (including indentation). + +.SH SEE ALSO +.BR xcb_connect (__libmansuffix__), +.BR xcb_get_property (__libmansuffix__), +.BR xcb_flush (__libmansuffix__) +.SH AUTHOR +Michael Stapelberg diff --git a/man/xcb-requests.man b/man/xcb-requests.man new file mode 100644 index 0000000..6b11883 --- /dev/null +++ b/man/xcb-requests.man @@ -0,0 +1,165 @@ +.TH xcb-requests __libmansuffix__ __xorgversion__ "XCB examples" +.ad l +.SH NAME +xcb-requests \- about request manpages +.SH DESCRIPTION +Every request in X11, like \fIMapWindow\fP, corresponds to a number of +functions and data structures in XCB. For \fIMapWindow\fP, XCB provides the +function \fIxcb_map_window\fP, which fills the \fIxcb_map_window_request_t\fP +data structure and writes that to the X11 connection. Since the \fIMapWindow\fP +request does not have a reply, this is the most simple case. + +.SH REPLIES + +Many requests have replies. For each reply, XCB provides at least a +corresponding data structure and a function to return a pointer to a filled +data structure. Let's take the \fIInternAtom\fP request as an example: XCB +provides the \fIxcb_intern_atom_reply_t\fP data structure and +\fIxcb_intern_atom_reply\fP function. For replies which are more complex (for +example lists, such as in \fIxcb_list_fonts\fP), accessor functions are +provided. + +.SH COOKIES + +XCB returns a cookie for each request you send. This is an XCB-specific data +structure containing the sequence number with which the request was sent to the +X11 server. To get any reply, you have to provide that cookie (so that XCB +knows which of the waiting replies you want). Here is an example to illustrate +the use of cookies: + +.nf +.sp +void my_example(xcb_connection *conn) { + xcb_intern_atom_cookie_t cookie; + xcb_intern_atom_reply_t *reply; + + cookie = xcb_intern_atom(conn, 0, strlen("_NET_WM_NAME"), "_NET_WM_NAME"); + /* ... do other work here if possible ... */ + if ((reply = xcb_intern_atom_reply(conn, cookie, NULL))) { + printf("The _NET_WM_NAME atom has ID %u\\n", reply->atom); + } + free(reply); +} +.fi + +.SH CHECKED VS. UNCHECKED + +The checked and unchecked suffixes for functions determine which kind of error +handling is used for this specific request. + +For requests which have no reply (for example \fIxcb_map_window\fP), errors +will be delivered to the event loop (you will receive an X11 event of type 0 +when calling \fIxcb_poll_for_event\fP). +If you want to explicitly check for errors in a blocking fashion, call the +_checked version of the function (for example \fIxcb_map_window_checked\fP) and +use \fIxcb_request_check\fP. + +For requests which have a reply (for example \fIxcb_intern_atom\fP), errors +will be checked when calling the reply function. To get errors in the event +loop instead, use the _unchecked version of the function (for example +\fIxcb_intern_atom_unchecked\fP). + +Here is an example which illustrates the four different ways of handling errors: + +.nf +.sp +/* + * Request without a reply, handling errors in the event loop (default) + * + */ +void my_example(xcb_connection *conn, xcb_window_t window) { + /* This is a request without a reply.
