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.

The advice is fine, except using XtAppAddActions is a more portable interface,
as XtAddActions will fail if you are not using XtInitialize().
When coding new programs please use XtApp* in favor of the non-app functions.
This will allow a more portable interface. If you do not have an app-context
handy then just use XtWidgetToApplicationContext.
