Защищенные методы

Метод	Описание
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.
OnTrackedElementMouseDown ( object sender, System.Windows.Input.MouseButtonEventArgs e ) : void
OnTrackedElementMouseMove ( object sender, System.Windows.Input.MouseButtonEventArgs e ) : void
OnTrackedElementMouseUp ( object sender, System.Windows.Input.MouseButtonEventArgs e ) : void
OnTrackedElementTouchDown ( object sender, System.Windows.Input.TouchEventArgs e ) : void	Called when a touch down event occurs on the TrackedElement.
OnTrackedElementTouchMove ( object sender, System.Windows.Input.TouchEventArgs e ) : void	Called when a touch move event occurs on the TrackedElement.
OnTrackedElementTouchUp ( object sender, System.Windows.Input.TouchEventArgs e ) : void	Called when a touch up event occurs on the TrackedElement.
TimestampToDateTime ( int timestamp ) : System.DateTime	Converts the timestamp provided in TouchEventArgs to a proper DateTime struct.
UnregisterEngine ( IGestureEngine engine ) : void	Removes all event handlers for the specified engine
