Bug 516425 – Optionally display accelerators in popups

2008-10-09  Michael Natterer  <mitch@imendio.com>

	Bug 516425 – Optionally display accelerators in popups

	* gtk/gtkuimanager.h (enum GtkUIManagerItemType): add value
	GTK_UI_MANAGER_POPUP_WITH_ACCELS which works like _POPUP but
	shows the actions' accelerators.

	* gtk/gtkuimanager.c: honor the new enum value for programmatically
	created UIs, and support <popup accelerators="true"> in the XML
	for the same purpose.
