gimp/app/widgets/gimpitemlistview.c
Michael Natterer f2ca257438 added descriptions to the GimpChannelType enum. 
2003-03-12  Michael Natterer  <mitch@gimp.org>

	* app/core/core-enums.[ch]: added descriptions to the
	GimpChannelType enum.

	* app/core/gimpimage.[ch]: added gimp_image_get_component_index()
	utility function which does the GIMP_RED_CHANNEL -> RED_PIX etc.
	mapping. Use it in all component getters/setters.

	* app/widgets/gimpcomponenteditor.[ch]: new widget implementing
	the component list using GtkListStore/GtkTreeView. Still a bit
	ugly because it uses the standard check instead of the eye icon.

	* app/widgets/gimpcomponentlistitem.[ch]: removed.

	* app/widgets/Makefile.am
	* app/widgets/widgets-types.h
	* app/widgets/gimpvectorslistview.c: changed accordingly.

	* app/widgets/gimpchannellistview.[ch]: create a GimpComponentEditor
	and removed the old GtkList based stuff.

	* app/widgets/gimpitemlistview.[ch]: keep around a pointer to the
	GimpMenuFactory passed to the constructor.

	* app/gui/channels-menu.c (channels_menu_update): do the right
	thing if "data" is a GimpComponentEditor.

	* app/gui/channels-commands.[ch]: ditto. Implemented duplicating
	of components and component to selection (bug #61018).
