gimp/app/widgets/gimpdockable.c
Michael Natterer c5fd48f2fb added a "menu_title" which is registered with each menu. 
2003-09-23  Michael Natterer  <mitch@gimp.org>

	* app/widgets/gimpmenufactory.[ch]: added a "menu_title" which is
	registered with each menu.

	* app/widgets/gimpitemfactory.[ch]: added the title to the
	constructor and to the GimpItemFactory struct.

	* app/gui/menus.c: register titles with all menus.

	* app/widgets/gimpdockable.[ch]: show the tab menu, not the
	contained dialog's menu when clicking on the menu button.
	Embed the dialog's menu as submenu. Use the item_factory's
	title and the dockable's stock_id for the submenu entry.

	* app/widgets/gimpeditor.c: removed GtkWidget:popup_menu()
	implementation since that's done by GimpDockable now.

	* app/widgets/gimpdockbook.c: set the new menu item invisible
	when showing the menu as tab menu.

	* app/widgets/gimphelp-ids.h: added GIMP_HELP_DOCK_TAB_DETACH
	and renamed _TAB_REMOVE to _TAB_CLOSE.

	* app/gui/dialogs-menu.c: added the new menu entry for showing the
	dialog's sub-menu. Added a "Detach" menu item, renamed "Remove" to
	"Close". Accept both a GimpDockbook and a GimpDockable pointer as
	"data" in dialogs_menu_update().

	* app/gui/dialogs-commands.[ch]: changed accordingly. Never use
	gtk_item_factory_popup_data_from_widget() but always the "data"
	passed to the callbacks. Take care to not set the already active
	preview_size, tab_style and list/grid type in the resp. callbacks
	to avoid being called from dialogs_menu_update().

	* app/gui/dialogs-constructors.c: removed separate
	set_context_funcs and get_menu_funcs for GimpContainerView and
	GimpContainerEditor widgets and simply use
	gimp_container_view_get_by_dockable() to find the right widget.
