The coordinates are always relative to the widget allocation. get_bounding_box_center: If there are touch sequences being currently handled by gesture, this function returns TRUE and fills in x and y with the center of the bounding box containing all active touches. Otherwise, FALSE will be returned. What's unclear? Both zoom and rotate are multitouch gestures and you usually want the center between the touches. _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gtk-list
