.SH ARGUMENTS

.IP \fIattributes\fP 1i

Specifies the structure from which the values (as specified by the value mask)

are to be taken.

The value mask should have the appropriate bits

set to indicate which attributes have been set in the structure.

.IP \fIbackground_pixel\fP 1i

Specifies the pixel that is to be used for the background.

.IP \fIbackground_pixmap\fP 1i

Specifies the background pixmap,

.ZN ParentRelative ,

or

.ZN None .

.IP \fIborder_pixel\fP 1i

Specifies the entry in the colormap. 

.IP \fIborder_pixmap\fP 1i

Specifies the border pixmap or

.ZN CopyFromParent .

.IP \fIdisplay\fP 1i

Specifies the connection to the X server.

.IP \fIvaluemask\fP 1i

Specifies which window attributes are defined in the attributes

argument.

This mask is the bitwise inclusive OR of the valid attribute mask bits.

If valuemask is zero,

the attributes are ignored and are not referenced.

.IP \fIw\fP 1i

Specifies the window.

.IP \fIcolormap\fP 1i

Specifies the colormap.

.SH DESCRIPTION

Depending on the valuemask,

the

.ZN XChangeWindowAttributes

function uses the window attributes in the

.ZN XSetWindowAttributes

structure to change the specified window attributes.

Changing the background does not cause the window contents to be

changed.

To repaint the window and its background, use 

.ZN XClearWindow .

Setting the border or changing the background such that the

border tile origin changes causes the border to be repainted.

Changing the background of a root window to 

.ZN None 

or 

.ZN ParentRelative

restores the default background pixmap.

Changing the border of a root window to

.ZN CopyFromParent

restores the default border pixmap.

Changing the win-gravity does not affect the current position of the

window.

Changing the backing-store of an obscured window to 

.ZN WhenMapped 

or

.ZN Always , 

or changing the backing-planes, backing-pixel, or

save-under of a mapped window may have no immediate effect.

Changing the colormap of a window (that is, defining a new map, not

changing the contents of the existing map) generates a 

.ZN ColormapNotify

event.

Changing the colormap of a visible window may have no

immediate effect on the screen because the map may not be installed

(see

.ZN XInstallColormap ).

Changing the cursor of a root window to 

.ZN None 

restores the default

cursor.

Whenever possible, you are encouraged to share colormaps.

.LP

Multiple clients can select input on the same window. 

Their event masks are maintained separately.

When an event is generated, 

it is reported to all interested clients. 

However, only one client at a time can select for 

.ZN SubstructureRedirectMask , 

.ZN ResizeRedirectMask , 

and

.ZN ButtonPressMask .

If a client attempts to select any of these event masks 

and some other client has already selected one, 

a

.ZN BadAccess

error results.

There is only one do-not-propagate-mask for a window, 

not one per client.

.LP

.ZN XChangeWindowAttributes

can generate

.ZN BadAccess ,

.ZN BadColor ,

.ZN BadCursor ,

.ZN BadMatch ,

.ZN BadPixmap ,

.ZN BadValue ,

and

.ZN BadWindow 

errors.

.LP

The

.ZN XSetWindowBackground

function sets the background of the window to the specified pixel value.

Changing the background does not cause the window contents to be changed.

.ZN XSetWindowBackground

uses a pixmap of undefined size filled with the pixel value you passed.

If you try to change the background of an 

.ZN InputOnly

window, a

.ZN BadMatch

error results.

.LP

.ZN XSetWindowBackground

can generate

.ZN BadMatch

and

.ZN BadWindow 

errors.

.LP

The

.ZN XSetWindowBackgroundPixmap

function sets the background pixmap of the window to the specified pixmap.

The background pixmap can immediately be freed if no further explicit

references to it are to be made.

If 

.ZN ParentRelative

is specified, 

the background pixmap of the window's parent is used,

or on the root window, the default background is restored.

If you try to change the background of an 

.ZN InputOnly

window, a

.ZN BadMatch

error results.

If the background is set to

.ZN None ,

the window has no defined background.

.LP

.ZN XSetWindowBackgroundPixmap

can generate

.ZN BadMatch ,

.ZN BadPixmap ,

and

.ZN BadWindow 

errors.

.LP 

The

.ZN XSetWindowBorder

function sets the border of the window to the pixel value you specify.

If you attempt to perform this on an

.ZN InputOnly

window, a

.ZN BadMatch

error results.

.LP

.ZN XSetWindowBorder

can generate

.ZN BadMatch

and

.ZN BadWindow 

errors.

.LP

The

.ZN XSetWindowBorderPixmap

function sets the border pixmap of the window to the pixmap you specify.

The border pixmap can be freed immediately if no further explicit

references to it are to be made.

If you specify

.ZN CopyFromParent ,

a copy of the parent window's border pixmap is used.

If you attempt to perform this on an

.ZN InputOnly

window, a

.ZN BadMatch

error results.

.LP

.ZN XSetWindowBorderPixmap

can generate

.ZN BadMatch ,

.ZN BadPixmap ,

and

.ZN BadWindow 

errors.

.LP

The

.ZN XSetWindowColormap

function sets the specified colormap of the specified window.

The colormap must have the same visual type as the window,

or a

.ZN BadMatch

error results.

.LP

.ZN XSetWindowColormap

can generate

.ZN BadColor ,

.ZN BadMatch ,

and

.ZN BadWindow 

errors.

.SH DIAGNOSTICS

.TP 1i

.ZN BadAccess

A client attempted

to free a color map entry that it did not already allocate.

.TP 1i

.ZN BadAccess

A client attempted

to store into a read-only color map entry.

.TP 1i

.ZN BadColor

A value for a Colormap argument does not name a defined Colormap.

.TP 1i

.ZN BadCursor

A value for a Cursor argument does not name a defined Cursor.

.TP 1i

.ZN BadMatch

Some argument or pair of arguments has the correct type and range but fails

to match in some other way required by the request.

.TP 1i

.ZN BadMatch

An

.ZN InputOnly

window locks this attribute.

.TP 1i

.ZN BadPixmap

A value for a Pixmap argument does not name a defined Pixmap.

.TP 1i

.ZN BadValue

Some numeric value falls outside the range of values accepted by the request.

Unless a specific range is specified for an argument, the full range defined

by the argument's type is accepted.  Any argument defined as a set of

alternatives can generate this error.

.TP 1i

.ZN BadWindow

A value for a Window argument does not name a defined Window.
