Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
static class	Behavior.Capturing<T extends Element<T>>	A click behavior that captures the pointer and optionally issues clicks based on some time based function.
static class	Behavior.Click<T extends Element<T>>	Implements clicking behavior.
static class	Behavior.Ignore<T extends Element<T>>	A behavior that ignores everything.
static class	Behavior.RapidFire<T extends Element<T>>	Captures the pointer and dispatches one click on press, a second after an initial delay and at regular intervals after that.
static class	Behavior.Select<T extends Element<T>>	Implements button-like behavior: selects the element when the pointer is in bounds, and deselects on release.
static class	Behavior.Toggle<T extends Element<T>>	Implements toggling behavior.
static class	Behavior.Track<T extends Element<T>>	Tracks the pressed position as an anchor and delegates to subclasses to update state based on anchor and drag position.

Method Summary

Modifier and Type	Method	Description
void	layout()	Called when our owner is laid out.
abstract void	onClick(Pointer.Interaction iact)	Called when the pointer is released and the subclass decides that it is a click, i.e.
void	onDrag(Pointer.Interaction iact)
void	onEnd(Pointer.Interaction iact)
abstract void	onHover(Pointer.Interaction iact, boolean inBounds)	Called as the user drags the pointer around after pressing.
abstract void	onPress(Pointer.Interaction iact)	Called when the pointer is pressed down on our element.
abstract boolean	onRelease(Pointer.Interaction iact)	Called when the pointer is released after having been pressed on this widget.
void	onStart(Pointer.Interaction iact)
void	soundAction()	Emits the action sound for our owner, if one is configured.

Constructor Details

Behavior

public Behavior(T owner)

Method Details

onStart

public void onStart(Pointer.Interaction iact)

Overrides:

onStart in class Pointer.Listener

onDrag

public void onDrag(Pointer.Interaction iact)

Overrides:

onDrag in class Pointer.Listener

onEnd

public void onEnd(Pointer.Interaction iact)

Overrides:

onEnd in class Pointer.Listener

layout

public void layout()

Called when our owner is laid out. If the behavior needs to resolve configuration via styles, this is where it should do it.

soundAction

public void soundAction()

Emits the action sound for our owner, if one is configured.

onPress

public abstract void onPress(Pointer.Interaction iact)

Called when the pointer is pressed down on our element.

onHover

public abstract void onHover(Pointer.Interaction iact,
 boolean inBounds)

Called as the user drags the pointer around after pressing. Derived classes map this onto the widget state, such as updating selectedness.

onRelease

public abstract boolean onRelease(Pointer.Interaction iact)

Called when the pointer is released after having been pressed on this widget. This should return true if the gesture is considered a click, in which case onClick(playn.scene.Pointer.Interaction) will be called automatically.

onClick

public abstract void onClick(Pointer.Interaction iact)

Called when the pointer is released and the subclass decides that it is a click, i.e. returns true from onRelease(playn.scene.Pointer.Interaction).
