Gimp/app/widgets/gimpcontainertreeview.c
Michael Natterer a446f3d7fb use the new tooltip API instead of the old deprecated one. Removed 
2007-11-09  Michael Natterer  <mitch@gimp.org>

	* libgimpwidgets/gimphelpui.[ch]: use the new tooltip API instead
	of the old deprecated one. Removed _gimp_help_init(). Remember
	whether tooltips are enabled or not in a local variable that can
	only be altered at startup time and not after. The API now expects
	markup instead of plain text which might cause warnings and
	perhaps needs to be changed.

	* libgimpwidgets/gimpwidgets-private.c: don't call _gimp_help_init().

	* app/config/gimpguiconfig.c: made show-tooltips a
	GIMP_CONFIG_PARAM_RESTART property.

	* app/widgets/gimptoolbox-color-area.c: don't add the tooltip here...

	* app/widgets/gimptoolbox.c: ...but here (as for all other
	indicators). Also escape '&' properly because we now use markup.

	* app/tools/gimpselectionoptions.c
	* app/widgets/gimpeditor.c
	* app/widgets/gimpwidgets-utils.c: print modifiers and
	shortcuts in bold instead of in ().

	* app/widgets/gimpcontainertreeview.c: show tooltips on rows if
	gimp_viewable_get_description() returns a tip.

	* app/dialogs/preferences-dialog.c
	* plug-ins/jpeg/jpeg-save.c
	* plug-ins/MapObject/mapobject_ui.c
	* plug-ins/Lighting/lighting_ui.c
	* plug-ins/common/animationplay.c
	* plug-ins/common/warp.c: no need to add event boxes just to have
	tooltips, the new ones work on all widgets.
