public class SoDoubleTapGestureRecognizer
extends SoGestureRecognizer

Double tap gesture recognizer. SoDoubleTapGestureRecognizer analyses touch events and recognizes a one finger double-tap gesture. It returns an SoDoubleTapGestureEvent with this gesture is recognized. The finger has to stay in a limitation area from the down event to the end one and must be completed within a maximum elapsed time. This recognizer only generates an END event.

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).
