Gimp/app/widgets/gimpcontrollerinfo.c
Michael Natterer 6d63d50040 guarded the whole header with GIMP_ENABLE_CONTROLLER_UNDER_CONSTRUCTION 
2004-11-24  Michael Natterer  <mitch@gimp.org>

	* libgimpwidgets/gimpcontroller.[ch]: guarded the whole header
	with GIMP_ENABLE_CONTROLLER_UNDER_CONSTRUCTION because it's no
	fixed API yet. Added a "state" property bacause "name" was abused
	as the controller's state. Added "help_domain" to the controller
	class.

	* libgimpwidgets/gimpwidgets.h: don't include gimpcontroller.h

	* modules/controller_linux_input.c
	* modules/controller_midi.c: set the "name" property to the name
	retrieved from the device, or to a default string if no name is
	available. Store the status in the "state" property. Added and
	changed some strings, but it's better to have the controller
	strings untranslated than to have no tooltips at all or misleading
	labels.

	* app/widgets/gimpcontrollerkeyboard.c
	* app/widgets/gimpcontrollerwheel.c: set default strings for both.

	* app/widgets/gimpcontrollereditor.c: added a GUI for the "state"
	property.

	* app/widgets/gimpcontrollerkeyboard.h
	* app/widgets/gimpcontrollerwheel.h
	* app/widgets/gimpcontrollerinfo.c
	* app/widgets/gimpcontrollers.c: #define
	GIMP_ENABLE_CONTROLLER_UNDER_CONSTRUCTION (just as in all files
	above).

	* app/widgets/gimphelp-ids.h: added the IDs of all controller
	modules and also of all other modules. The defines are not
	actually used, but this file is the canonical place to collect all
	the core's help IDs.
