[Glade-users] extend Drawing Area class

Ahh, back to the original problem :-P

the initial problem was that the custom class didn't seem to have
created the underlying Gtk::DrawingArea object. The passing in of
"BaseObjectType *cobject" seems to be what takes care of that in
libglademm. I assume libglademm and normal glade are separate? Can
Glade be used to generate libglademm compatible code?
