I think this is at the root of my problem. I wanted a window with a drawing 
area and a menu. Being lazy, I just let my widget inherit Gtk_DrawingArea
and added a Gtk_Window. In retrospect, inheriting from Gtk_Window (and just
adding  a drawing area) would have been better although I really like the
convenience  of being able to say myDrawArea->drawLine (....).

Agreed, since they involve a drawing area ...
