Anything you draw into the XmDrawingArea should be clipped
by the windows of it's children, unless you set subwindow_mode
to IncludeInferiors in your GC.  If you didn't do that, then are you sure
that the child buttons are Widgets and not Gadgets?
Gadgets don't have windows so your graphics wouldn't be clipped.
