keysym_return)
Display *display;
KeyCode keycode;
Modifiers modifiers;
Modifiers *modifiers_return;
KeySym *keysym_return;
void XtRegisterCaseConverter(display, proc, start, stop)
Display *display;
XtCaseProc proc;
KeySym start;
KeySym stop;
void XtConvertCase(display, keysym, lower_return, upper_return)
Display *display;
KeySym keysym;
KeySym *lower_return;
KeySym *upper_return;
Arguments
display Specifies the display.
keycode Specifies the KeyCode to translate.
keysym Specifies the KeySym to convert.
keysymreturn
Returns the resulting KeySym.
lowerreturn
Returns the lowercase equivalent of the KeySym.
upperreturn
Returns the uppercase equivalent of the KeySym.
modifiers Specifies the modifiers to the KeyCode.
modifiersreturn
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 con-
verters; you need to register an identity converter. When a new con-
verter 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.
