XtSetKeyTranslator, XtTranslateKeycode,
XtRegisterCaseConverter, XtConvertCase - convert KeySym to KeyCodes
- 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
- *lower_return, KeySym *upper_return);
- display
- Specifies the displayDi.
- 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.
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.
