2001-07-15 James Henstridge <james@daa.com.au> * gtk/gtkwindow.c (gtk_window_add_accel_group): cast to GObject. (gtk_window_remove_accel_group): same here. (gtk_window_key_press_event): same here. * gtk/gtkwidget.c (gtk_widget_add_accelerator): cast to GObject. (gtk_widget_remove_accelerator): same here. (gtk_widget_remove_accelerators): same here. * gtk/gtkplug.c (gtk_plug_accel_entries_changed): same here. * gtk/gtkmenushell.c (gtk_menu_shell_key_press): cast to GObject instead of GtkObject. * gtk/gtkmenu.c (gtk_menu_key_press): update since GtkAccelGroup now takes GObjects. * gtk/gtkitemfactory.c (gtk_item_factory_propagate_accelerator): pass a GObject to gtk_accel_group_entries_from_object. (gtk_item_factory_create_item): s/accel_widget/accel_object/ * gtk/gtk-boxed.defs: remove GtkAccelGroup boxed def. * gtk/gtkaccellabel.c: convert to handle GObject accel objects. * gtk/gtkaccellabel.h: fix header to reflect that arbitrary GObjects can have accelerators set now. Add compatibility defines. * gtk/gtkmarshal.list: add missing marshallers. * gtk/gtkaccelgroup.[ch]: convert to a GObject, and allow setting accelerators on plain GObjects. gtk_accel_group_object_destroy has been converted into a weak reference, and gtk_accel_group_delete_entries is now a destroy notify for that piece of data.
