attach/detach to menu widget via

Browse Source 
Tue Feb  3 15:09:55 1998  Tim Janik  <timj@gimp.org>

        * gtk/gtkoptionmenu.h:
        * gtk/gtkoptionmenu.c: attach/detach to menu widget via

        * gtk/gtkmenu.h:
        * gtk/gtkmenu.c: new functions gtk_menu_attach_to_widget
          and gtk_menu_detach that correspond to the action of
          gtk_widget_set_parent and gtk_widget_unparent.

        * gtk/widget.c: few fixups.
