Detailed Description

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().
