bgo417389 - Scrollwheel for GtkPathBar
2008-03-03  Carlos Garnacho  <carlos@imendio.com>

	Fix http://bugzilla.gnome.org/show_bug.cgi?id=417389 - Make the
	scrollwheel work in GtkPathBar.

	* gtk/gtkpathbar.h (struct _GtkPathBar): New field event_window.

	* gtk/gtkpathbar.c (gtk_path_bar_realize): New function.  Create
	an input-only window, event_window, which we'll use to capture
	scroll events.
	(gtk_path_bar_map): Show the event_window under the rest of the
	windows, so it will be a catch-all for unhandled events.
