NAME

  XtSetKeyTranslator, XtTranslateKeycode, XtRegisterCaseConverter,
  XtConvertCase - convert KeySym to KeyCodes


SYNOPSIS

  void XtSetKeyTranslator(display, proc)
	  Display *display;
	  XtKeyProc proc;

  void XtTranslateKeycode(display, keycode, modifiers, modifiers_return,
  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.

  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.
