Fri Sep 1 22:39:07 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkmenu.[ch] TODO.xml: Apply patch from Nils Barth and David Santiago to improve submenu navigation. The patch does this by creating a triangular region from the point where the pointer leaves the menu to the submenu. While the pointer is in that region and a timeout has not expired, events that would cause the active submenu to change are ignored.
