Package tripleplay.gesture

Class GestureRegionDirector

java.lang.Object

react.Slot<Object>

playn.scene.Touch.Listener

tripleplay.gesture.GestureRegionDirector

All Implemented Interfaces:

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

public class GestureRegionDirector
extends Touch.Listener

Handles multiple GestureDirectors listening on a single layer. A GestureDirector is only given a touch start event if it originated within that director's region bounds. It is only given one of the other events if that event is for a touch that started within that director's region bounds.

Constructor Details

GestureRegionDirector

public GestureRegionDirector(Platform plat,
 Timer timer)

Creates an uninitalized GestureRegionDirector. setLayer() must be called separately.

GestureRegionDirector

public GestureRegionDirector(Platform plat,
 Timer timer,
 Layer layer,
 pythagoras.f.IRectangle bounds)

Creates a GestureRegionDirector with default options.

Parameters:

bounds - The bounds in which to react to touch events.

Method Details

setLayer

public GestureRegionDirector setLayer(Layer layer,
 pythagoras.f.IRectangle bounds)

remove

public void remove()

getRegions

public Collection<GestureDirector> getRegions()

getRegion

public GestureDirector getRegion(float x,
 float y,
 float width,
 float height)

Gets a Region instance bounded by the given dimensions. The given bounds will restricted to the given bounds of this GestureRegionDirector, and null may be returned if suitable bounds are not found or a conflicting region was already defined on this GestureRegionDirector.

getRegion

public GestureDirector getRegion(pythagoras.f.IRectangle bounds)

Gets a Region instance bounded by the given dimensions. The given bounds will be restricted to the given bounds of this GestureRegionDirector, and null may be returned if suitable bounds are not found or a conflicting region was already defined on this GestureRegionDirector.

getPercentRegion

public GestureDirector getPercentRegion(float perX,
 float perY,
 float perWidth,
 float perHeight)

Gets a region bounded by the given dimensions as defined as percentages of this GestureRegionDirector's defined bounds. Null may be returned if suitable bounds are not found or a conflicting Region was already defined on this GestureRegionDirector.

getPercentRegion

public GestureDirector getPercentRegion(pythagoras.f.IRectangle bounds)

Gets a Region instance bounded by the given dimensions as defined as percentages of this GestureRegionDirector's defined bounds. Null may be returned if suitable bounds are not found or a conflicting Region was already defined on this GestureRegionDirector.
