Field Details

HOVER_LIMIT

public static Style<Float> HOVER_LIMIT

A distance, in event coordinates, used to decide if tracking should be temporarily cancelled. If the pointer is hovered more than this distance outside of the owner's bounds, the tracking will revert to the anchor position, just like when the pointer is cancelled. A null value indicates that the tracking will be unconfined in this way. TODO: default to 35 if no Slider uses are relying on lack of hover limit.

Method Details

onPress

public void onPress(Pointer.Interaction iact)

Description copied from class: Behavior

Called when the pointer is pressed down on our element.

Overrides:

onPress in class Behavior.Ignore<T extends Element<T>>

onHover

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

Description copied from class: Behavior

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

Overrides:

onHover in class Behavior.Ignore<T extends Element<T>>

onRelease

public boolean onRelease(Pointer.Interaction iact)

Description copied from class: Behavior

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 Behavior.onClick(playn.scene.Pointer.Interaction) will be called automatically.

Overrides:

onRelease in class Behavior.Ignore<T extends Element<T>>

onCancel

public void onCancel(Pointer.Interaction iact)

Overrides:

onCancel in class Behavior.Ignore<T extends Element<T>>

layout

public void layout()

Description copied from class: Behavior

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

Overrides:

layout in class Behavior<T extends Element<T>>
