.HP

void XtTranslateKeycode(Display *\fIdisplay\fP, KeyCode \fIkeycode\fP,

Modifiers \fImodifiers\fP, Modifiers *\fImodifiers_return\fP, KeySym

.HP

void XtConvertCase(Display *\fIdisplay\fP, KeySym \fIkeysym\fP, KeySym

*\fIlower_return\fP, KeySym *\fIupper_return\fP);

.SH ARGUMENTS

.ds Di

.IP \fIdisplay\fP 1i

Specifies the display\*(Di.

.IP \fIkeycode\fP 1i

Specifies the KeyCode to translate.

.IP \fIkeysym\fP 1i

Specifies the KeySym to convert.

.IP \fIkeysym_return\fP 1i

Returns the resulting KeySym.

.IP \fIlower_return\fP 1i

Returns the lowercase equivalent of the KeySym.

.IP \fIupper_return\fP 1i

Returns the uppercase equivalent of the KeySym.

.IP \fImodifiers\fP 1i

Specifies the modifiers to the KeyCode.

.IP \fImodifiers_return\fP 1i

Returns a mask that indicates the modifiers actually used

to generate the KeySym.

.ds Pr \ to perform key translations or conversions

.IP \fIproc\fP 1i

Specifies the procedure that is\*(Pr.

.IP \fIstart\fP 1i

Specifies the first KeySym for which this converter is valid.

.IP \fIstop\fP 1i

Specifies the last KeySym for which this converter is valid.

.SH DESCRIPTION

The

.ZN XtSetKeyTranslator

function sets the specified procedure as the current key translator.

The default translator is

.ZN XtTranslateKey ,

an

.ZN XtKeyProc

that uses Shift and Lock modifiers with the interpretations defined

by the core protocol.

It is provided so that new translators can call it to get default

KeyCode-to-KeySym translations and so that the default translator

can be reinstalled.

.LP

The

.ZN XtTranslateKeycode

function passes the specified arguments

directly to the currently registered KeyCode to KeySym translator.

.LP

The

.ZN XtRegisterCaseConverter

registers the specified case converter.

The start and stop arguments provide the inclusive range of KeySyms

for which this converter is to be called.

The new converter overrides any previous converters for KeySyms in that range.

No interface exists to remove converters;

you need to register an identity converter.

When a new converter is registered,

the \*(xI  refreshes the keyboard state if necessary.

The default converter understands case conversion for all

KeySyms defined in the core protocol.

.LP

The

.ZN XtConvertCase

function calls the appropriate converter and returns the results.

A user-supplied

.ZN XtKeyProc

may need to use this function.
