touchmove - Sent when a given event moves on the surface.\n *   
touchend - Sent when a given event lifts from the surface.\n *   
touchcancel - Sent when the system cancels tracking for the touch.\n * 
\n * TouchEvent objects are combined together to form high-level GestureEvent\n * objects that are also sent during a multi-touch sequence.
