Thu Nov 27 16:19:03 2003 Tim Janik <timj@gtk.org> * gtk/gtkmenu.c: allow accel activation depending on sensitivity and the attach widget. * gtk/gtkmenuitem.c: allow accel activation depending on visibility, sensitivity and the parent menu. * gtk/gtkwidget.[hc]: introduced ::can-activate-accel signal which checks whether accelerators may activate a widget. the default handler demands the widget be sensitive and visible+viewable. * gtk/gtkaccelgroup.[hc]: export gtk_accel_group_activate().
