Very sorry, I still don't see it.

As far as I can see, Gdk_Window is not in the GtkAda type hierarchy.
Did you mean I have to use Gtk.Get_Object to get the address, and
then use Gdk.Convert to convert to Gdk_Window?
Why did you use Unchecked_Conversion and not
System.Address_To_Access_Conversions in the Gdk spec?

Thanks,
