Tim Janik c2c98d9e12 some cleanups, fixed mnemonic_widget handling, added PROP_MNEMONIC_WIDGET. 
Thu Mar 22 13:01:44 2001  Tim Janik  <timj@gtk.org>

        * gtk/gtklabel.[hc]: some cleanups, fixed mnemonic_widget handling,
        added PROP_MNEMONIC_WIDGET.

        * gtk/gtkwindow.c (gtk_window_activate_mnemonic):
        (gtk_window_remove_mnemonic):
        (gtk_window_add_mnemonic): fixed assertions.
        (gtk_window_activate_mnemonic): constrain modifier checks to those
        permitted by gtk_accelerator_get_default_mod_mask().
        got rid of gtk_window_get_default_accel_group().

        * gtk/gtkwidget.c (gtk_widget_real_activate_mnemonic): handle non
        activatable widgets either by focussing or a warning.
        added a signal accumulator to ::activate_mnemonic which stops the
        emission once a handler returned TRUE.
