Package tripleplay.gesture

Class GestureDirector

java.lang.Object

react.Slot<Object>

playn.scene.Touch.Listener

tripleplay.gesture.GestureDirector

All Implemented Interfaces:

react.Reactor.RListener, react.SignalView.Listener<Object>, react.ValueView.Listener<Object>

public class GestureDirector
extends Touch.Listener

Resolves user touch input in terms of a set of Gestures that are registered with this director. May either be used as a standalone listener on a layer, or along with a set of other regions in a given layer via GestureRegionDirector. Will only consider touches that start within the defined bounds, but if it is given touch events that end outside of the bounds, but started inside the bounds it will react to them.

public GestureDirector(Platform plat,
 pythagoras.f.IRectangle bounds,
 Timer timer)

Method Details

add

public GestureDirector add(Gesture<?> gesture)

Adds a gesture to the set considered during each user interaction. Returns this director for chaining.

remove

public boolean remove(Gesture<?> gesture)

Removes the given gesture from the set considered during each user interaction. Returns false if that gesture was not found.

touchInBounds

public boolean touchInBounds(Touch.Interaction iact)

trackingTouch

public boolean trackingTouch(Touch.Event touch)

greedyGesture

public react.ValueView<Gesture<?>> greedyGesture()

pauseDelay

public int pauseDelay()

Returns the number of milliseconds to wait after the last touch event to transition the current gestures to PAUSE.

setPauseDelay

public GestureDirector setPauseDelay(int value)

Sets the number of milliseconds to wait after the last touch even to transition the current guestures to PAUSE. The default is 500 (half a second).

Returns:

this GestureDirector for call chaining.
