public class SoGestureRecognizer
extends Inventor

Base class for all gesture recognizers. A gesture recognizer analyzes touch events and translates them into corresponding gesture events.

Note:

• In order to get touch events for the gesture recognizer(s) to recognize, the application must explicitly register a touch screen device (
  invalid reference

  SoWinTouchScreen

  ,
  invalid reference

  SoQtTouchScreen

  , etc).
• In order to get gesture events, the application must explicitly register gesture recognizers with the touch screen device's touch manager (SoTouchManager).
