public class SoRotateGestureEvent
extends SoGestureEvent
```
Class for rotate gesture events. SoRotateGestureEvent represents a two finger rotate gesture in the Open Inventor event model. Touch events are analyzed by a SoRotateGestureRecognizer. When a rotate gesture is recognized, the recognizer generates this event. The gesture begins with a BEGIN state event. DELTA state events are generated until the end of the gesture which generates an END state event. See SoGestureEvent.getGestureState().
Note:
- In order to get touch events for the gesture recognizer(s) to recognize, the application must explicitly register a touch screen device (SoWinTouchScreen, SoQtTouchScreen, etc).
- In order to get gesture events, the application must explicitly register gesture recognizers with the touch screen device's touch manager (SoTouchManager).
