| You might want to look at the examples/doublebuffer directory in the GtkAda

Talking about the Gtk_Double_Buffer, why hasn't it made its way in the GtkAda.*
hierarchy ? I find it's a very useful widget and use it regularly, so it
would be nice to have it "at hand", and not to go and fetch it in the
Examples directory.

Just a suggestion...
