Class ActorGestureListener

java.lang.Object

com.badlogic.gdx.scenes.scene2d.utils.ActorGestureListener

All Implemented Interfaces:

EventListener

public class ActorGestureListener
extends java.lang.Object
implements EventListener

Detects tap, long press, fling, pan, zoom, and pinch gestures on an actor. If there is only a need to detect tap, use ClickListener.

Method Detail

handle

public boolean handle(Event e)

Description copied from interface: EventListener

Try to handle the given event, if it is applicable.

Specified by:

handle in interface EventListener

Returns:

true if the event should be considered handled by scene2d.

touchDown

public void touchDown(InputEvent event,
                      float x,
                      float y,
                      int pointer,
                      int button)

touchUp

public void touchUp(InputEvent event,
                    float x,
                    float y,
                    int pointer,
                    int button)

tap

public void tap(InputEvent event,
                float x,
                float y,
                int count,
                int button)

longPress

public boolean longPress(Actor actor,
                         float x,
                         float y)

If true is returned, additional gestures will not be triggered. No event is provided because this event is triggered by time passing, not by an InputEvent.

fling

public void fling(InputEvent event,
                  float velocityX,
                  float velocityY,
                  int button)

pan

public void pan(InputEvent event,
                float x,
                float y,
                float deltaX,
                float deltaY)

The delta is the difference in stage coordinates since the last pan.

panStop

public void panStop(InputEvent event,
                    float x,
                    float y,
                    int pointer,
                    int button)

zoom

public void zoom(InputEvent event,
                 float initialDistance,
                 float distance)

pinch

public void pinch(InputEvent event,
                  Vector2 initialPointer1,
                  Vector2 initialPointer2,
                  Vector2 pointer1,
                  Vector2 pointer2)

getGestureDetector

public GestureDetector getGestureDetector()

getTouchDownTarget

@Null
public Actor getTouchDownTarget()
