Wed Nov 12 21:40:10 2003 Matthias Clasen <maclas@gmx.de> Changes to improve menu positioning on Xinerama (#108328): * gtk/gtkmenu.c (struct _GtkMenuPrivate): Add a menu_num field to store the monitor on which the menu is to be positioned. * gtk/gtkmenu.[hc] (gtk_menu_position): Store the monitor number in the GtkMenuPrivate struct and fetch the monitor geometry after calling the position_func, in case it has been changed. * gtk/gtkmenu.c (gtk_menu_set_monitor): New function to be used in GtkMenuPositionFunc implementations for setting the monitor_num field in GtkMenuPrivate. * gtk/gtkmenuitem.c (gtk_menu_item_position_menu): Call gtk_menu_set_monitor.
