RE: [gtkmm] Double Window Hell

[Murray Cumming Comneon com]

1. I think that get_derived_widget() should make this much simpler.
2. I think that add() is much simpler than reparent_window().

The libglademm examples should show this. If the libglademm examples don't
show how to do something, then please tell us what they don't show.
