You must get the requisition of your menu in this function with gtk_widget_size_request(), and to get the bottom of menu at the cursor you would just have to substract the req.height to y. Hint: GtkRequisition req; gtk_widget_size_request (menu, &req); *y -= req.height; Mike _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
