The example of FileSelector doesn't catch the clicked signal of the Ok button,
and i have the impression that it's because in GTK2.0 the signal registration
is dynamic. In org.gnu.gtk.event.ButtonEvent types of signal are allocated
as 1, 2, 3... were they should be get by using g_signal_lookup. My impression
is that if buttons are created first everything is fine because signals are
registered in the expected order, but in the FileSelectionBox the Gtk core
registers other signal before registering the signal for Button, so it's not
anymore 1, 2, 3.... And finally as the signal aren't registered correctly the
corresponding callbacks are never called.
Please correct me if i'm wrong, and consider telling me "It's late your should
be sleeping, or please drink another cup of coffee".
