nautilus r14332 - in trunk: . src

New Revision: 14332
URL: http://svn.gnome.org/viewvc/nautilus?rev=14332&view=rev

Log:
2008-07-09  Christian Neumair  <cneumair gnome org>

	* src/nautilus-places-sidebar.c (compute_drop_position),
	(drag_motion_callback), (reorder_bookmarks),
	(drag_data_received_callback), (nautilus_places_sidebar_init):
	Bookmark DND fix galore. Properly handle reordering when non-existing
	bookmarks are present. They are ignored by the view, but not by the
	Nautilus bookmark list. Make DND indication consistent with the GTK+
	file chooser.
