You need to add an action for your routine, i.e.:


        static XtActionsRec actionsList[] =
        {
                { "draw_graphics", DrawGraphics },
        };

	...

        XtAddActions(actionsList, 1);


I added the action before Realizing the toplevel widget, and my
DrawGraphics() routine gets called when a ConfigureNotify or
Expose event occurs.

I have constructed a simple example of using X graphics calls with
a widget if you or anyone else is interested.  It is small and isolates
the toolkit eXpert from having to use a lot of Xlib calls.
