2547.0. "Who's Right Documentation or ???" by RHETT::MACEACHERN () Fri Mar 30 1990 11:36

    I have a customer who is trying to use the Unrealize widget command
    (XtUnRealizeWidget).  His problem is that when he looks into the
    include file for intrinsics it indicates that the command needs no
    parameter passed, i.e.  the command should be XtUnRealizeWidget().
    The documentation (Page 2-228 of volume 1B Toolkit Routines) say that
    the widget id is needed.
    
    Who is right.  Obviously, if he used the include file for intrinsics
    he should not include the widget id, but then how does the routine
    know which widget to unrealize.
    
    I think I have rambled long enough.  Thanks for any help
    
    Dave.

	Of course they need to pass a widget ID. I think that a prototype routine definition (in an .h file) that has no arguments means that the argument list won't be checked, not that there are no arguments to the real function. They should beware, however, that unrealizing a widget is "pushing the functionality envelope". By that, I mean that there have been several QARs, etc, reported in this area and that it does not always do what is expected. (But it probably is better than XtDestroyWidget.) (:?) -steve-
