Interface GestureEvent

public interface GestureEvent

The GestureEvent interface class is used by an application to receive gesture recognition events from the platform.

The API imposes the restriction that the gesture event data is only valid during the call to GestureListener.gestureAction(java.lang.Object, com.nokia.mid.ui.gestures.GestureInteractiveZone, com.nokia.mid.ui.gestures.GestureEvent).

Method Summary
 int getDragDistanceX()
          Query for the Drag & Drop gesture events movement in horizontal direction since last drag gesture.
 int getDragDistanceY()
          Query for the Drag & Drop gesture events movement in vertical direction since last drag gesture.
 float getFlickDirection()
          Query for the Flick gesture events direction.
 int getFlickSpeed()
          Query for the Flick gesture events speed in actual flick direction.
 int getFlickSpeedX()
          Query for the Flick gesture events speed in horizontal direction.
 int getFlickSpeedY()
          Query for the Flick gesture events speed in vertical direction.
 int getStartX()
          Query for the gestures horizontal start location.
 int getStartY()
          Query for the gestures vertical start location.
 int getType()
          Query for the actual gesture event that has occurred.
