Name

XtConvertCase — determine upper-case and lower-case versions of a keysym. 

Synopsis

void XtConvertCase(display, keysym, lower_return, upper_return)

    Display ∗display;
    KeySym keysym;
    KeySym ∗lower_return;
    KeySym ∗upper_return;

Arguments

displaySpecifies the display that the keysym came from. 

keysymSpecifies the keysym to convert. 

lower_return
Returns the lower-case equivalent of the keysym.

upper_return
Returns the upper-case equivalent of the keysym.

Description

XtConvertCase is used to determine upper-case and lower-case equivalents for a keysym.  It calls the case converter that is currently registered to convert those keysyms and returns the results.  This procedure can perform application-specific shifting of characters. 

A user-supplied XtKeyProc may need to use this function. 

XtRegisterCaseConverter can be used to register a new case converter. 

For a more detailed discussion of processing keyboard input, see Chapter 13, Miscellaneous Toolkit Programming Techniques, in Volume Four, X Toolkit Intrinsics Programming Manual.  See Chapter 9, The Keyboard and Pointer, in Volume One, Xlib Programming Manual, for more information on keysyms.
