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.

XtSetKeyTranslator(3Xt) XT FUNCTIONS XtSetKeyTranslator(3Xt)
start Specifies the first KeySym for which this con-
verter is valid.
stop Specifies the last KeySym for which this con-
verter is valid.
DESCRIPTION
The XtSetKeyTranslator function sets the specified proce-
dure as the current key translator. The default transla-
tor 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 argu-
ments 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 con-
verters for KeySyms in that range. No interface exists to
remove converters; you need to register an identity con-
verter. When a new converter is registered, the Intrin-
sics 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.
