public class SoLongTapGestureRecognizer
extends SoGestureRecognizer

Long tap gesture recognizer. SoLongTapGestureRecognizer analyses touch events and recognizes a one finger long-tap (touch-and-hold) gesture. It returns an SoLongTapGestureEvent with the long tap duration if this gesture is recognized. The finger has to stay in a limitation area from the down event to the up event and must stay down for a minimum period of 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 (
  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).
