gre.outbound

A mouse/touch has left a control (if dragging a pointer or finger) and there are no remaining fingers in the control boundary. This event is generated once the coordinates leave a control boundary. If mouse motion events are not supported on the platform then this event will not be generated.

note

Control groups can not receive outbound events.
