Hi --

    I've got a Motif application that uses a drawing area widget.  I'd like
to have a callback routine called when the window associated with that
widget is mapped.  Unfortunately, I seem unable to accomplish this -- the
attempt to specify a map callback routine is met with an error message :

	"Warning: Cannot find callback list in XtAddCallbacks"

which, of course, one would expect, given that there is no reference to
a map callback in anything but Xm.h.

    Is there any way to get a callback when a widget's window is mapped?
Any help would be appreciated. . . :-)

- Philip
