Class ElementGestureListener

java.lang.Object

arc.scene.event.ElementGestureListener

All Implemented Interfaces:

EventListener

public class ElementGestureListener
extends Object
implements EventListener

Method Details

handle

public boolean handle(SceneEvent 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,
 KeyCode button)

touchUp

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

tap

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

longPress

public boolean longPress(Element 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,
 KeyCode 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.

zoom

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

pinch

public void pinch(InputEvent event,
 Vec2 initialPointer1,
 Vec2 initialPointer2,
 Vec2 pointer1,
 Vec2 pointer2)

getGestureDetector

public GestureDetector getGestureDetector()

getTouchDownTarget

public Element getTouchDownTarget()
