NAME
XtSetKeyTranslator, XtTranslateKeycode, XtRegisterCaseConverter, XtConvertCase -
convert KeySym to KeyCodes
SYNTAX
void
XtSetKeyTranslator(Display * display, XtKeyProc proc);
void
XtTranslateKeycode(Display * display, KeyCode keycode, Modifiers
modifiers, Modifiers *modifiers_return, KeySym *
keysym_return);
void
XtRegisterCaseConverter(Display * display, XtCaseProc proc,
KeySym start, KeySym stop);
void
XtConvertCase(Display * display, KeySym keysym, KeySym *

ARGUMENTS
- display
- Specifies the display.
- keycode
- Specifies the KeyCode to translate.
- keysym
- Specifies the KeySym to convert.
- keysym_return
- Returns the resulting KeySym.
- lower_return
- Returns the lowercase equivalent of the KeySym.
- upper_return
- Returns the uppercase equivalent of the KeySym.
- modifiers
- Specifies the modifiers to the KeyCode.
- modifiers_return
- Returns a mask that indicates the modifiers actually used
to generate the KeySym.
- proc
- Specifies the procedure that is to perform key
translations or conversions.
- start
- Specifies the first KeySym for which this converter is
valid.
- stop
- Specifies the last KeySym for which this converter is
valid.
DESCRIPTION
The
XtSetKeyTranslator function sets the specified procedure as the
current key translator. The default translator is
XtTranslateKey, an
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.
The
XtTranslateKeycode function passes the specified arguments directly
to the currently registered KeyCode to KeySym translator.
The
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
Intrinsics refreshes the keyboard state if necessary. The default converter
understands case conversion for all KeySyms defined in the core protocol.
The
XtConvertCase function calls the appropriate converter and returns
the results. A user-supplied
XtKeyProc may need to use this function.
