Matthias Clasen 0ceb0db081 Install accelerators on actions, not on proxies, support accelerator-only
2003-09-18  Matthias Clasen  <maclas@gmx.de>

	Install accelerators on actions, not on proxies, support
	accelerator-only actions:

	* gtk/gtkmenu.c (get_accel_path): New function to get the accel path
	and its lock status either via _gtk_widget_get_accel_path() or by
	looking at the accel_path stored in the menu item itself and determining
	its lock status by peeking into the contained accel label. This was
	already (accidentally) committed a week ago.

	* gtk/gtkaction.h (gtk_action_set_accel_group):
	(gtk_action_[dis]connect_accelerator): New functions.

	* gtk/gtkaction.c (struct _GtkActionPrivate): Add accel_group,
	accel_closure and accel_count. We must have a reference to the accel_group,
	since we need it in connect_proxy. The count is necessary to ensure
	that the accelerator isn't removed before the last proxy requesting
	it has been unmerged.
	(connect_proxy): Connect the accelerator to the
	action now, only set the accel_path on the menuitem.
	(remove_proxy): Disconnect the accelerator from the action, not from
	the menuitem.
	(gtk_action_set_accel_group): Set the accel group.
	(gtk_action_[dis]connect_accelerator): Count the number of times
	this functions have been called and install/remove the accelerator if
	the count leaves/reaches zero.

	* gtk/gtkuimanager.h (GtkUIManagerItemType): Add
	GTK_UI_MANAGER_ACCELERATOR.

	* gtk/gtkuimanager.c (NodeType): Add NODE_TYPE_ACCELERATOR.
	(start_element_handler): Create NODE_TYPE_ACCELERATOR nodes from
	<accelerator> elements.
	(gtk_ui_manager_add_ui): Create NODE_TYPE_ACCELERATOR nodes when
	type is GTK_UI_MANAGER_ACCELERATOR.
	(update_node): Set the accel group on actions before creating their
	proxies. Don't set the accel group on created menus. For
	NODE_TYPE_ACCELERATOR nodes, [dis]connect the actions' accelerator.
	(print_node): Also emit <accelerator> elements.

	* tests/testmerge.c (dump_accels): Add a "Dump Accels" button.
