Tue Nov 12 15:13:58 2002  Owen Taylor  <otaylor@redhat.com>

        * gtk/gtkwidget.c gtk/gtkwindow.[ch]: Add
        _gtk_window_unset_focus_and_default(), use to clear
        the focus and default out of parts of the widget
        heirarchy that we are hiding.

        * gtk/gtkwidget.c (gtk_widget_propagate_screen_changed_recurse):
        Fix typo that was resulting in missed screen-change
        notifies.

        * gtk/gtkwindow.c (do_focus_change): Allow for
        widget->window == NULL.

        * gtk/gtklabel.c (gtk_label_screen_changed): Clear the
        layout here not in hierarchy changed to handle the case
        where the toplevel was moved between screens.
