- * CGEstureEngine handles the processing of the UI events.
- * It acts as a stmUiEventEngine::MUiEventObserver to receive the UI events.
- * The gesture recognisers are stored in a list, and at each HandleUiEventL the
- * list of gesture recognisers is processed. The first one to return EGestureActive
- * from the recognise method "owns" the gesture. If some other recogniser owned it
- * previously, its release method is called. Gesture recogniser can also lock the gesture
- * by returning ELockToThisGesture. Then only that gesture recogniser will be called
- * until release is detected or the recogniser returns something else than ELockToThisGesture.
