Méthode	Description
CreateAndSetupGestureEngine ( System.Windows.Input.MouseDevice device ) : IGestureEngine	Creates and setups event listeners for a new gesture engine.
CreateAndSetupGestureEngine ( System.Windows.Input.TouchDevice device ) : IGestureEngine	Creates and setups event listeners for a new gesture engine.
OnGestureAborted ( IGestureEngine engine ) : void	Called when an engine aborts its gesture recognition. Typically this is done when the touch events doesn't match the engine's gesture but can it can also be aborted for other reasons.
OnGestureCompleted ( IGestureEngine engine ) : void	Called when an engine has successfully recognized a gesture.
OnGestureStarted ( IGestureEngine engine ) : void	Called when an engine starts to recognize gestures
OnStopTracking ( ) : void	Called when the TrackedElement is no longer tracked for touch events.
