Constructor Summary

Constructors

Modifier	Constructor and Description

Method Summary

Modifier and Type	Method and Description
void	dispose() Called by a Skinnable when the Skin is replaced on the Skinnable.

Field Detail

IS_TOUCH_SUPPORTED

protected static final boolean IS_TOUCH_SUPPORTED

A static final reference to whether the platform we are on supports touch.

behavior

private BB extends BehaviorBase<C> behavior

The BehaviorBase that encapsulates the interaction with the Control from this Skin. The Skin does not modify the Control directly, but rather redirects events into the BehaviorBase which then handles the events by modifying internal state and public state in the Control. Generally, specific Skin implementations will require specific BehaviorBase implementations. For example, a ButtonSkin might require a ButtonBehavior.

changeListenerHandler

private MultiplePropertyChangeListenerHandler changeListenerHandler

This is part of the workaround introduced during delomboking. We probably will want to adjust the way listeners are added rather than continuing to use this map (although it doesn't really do much harm).

mouseHandler

private final EventHandler<MouseEvent> mouseHandler

Forwards mouse events received by a MouseListener to the behavior. Note that we use this pattern to remove some of the anonymous inner classes which we'd otherwise have to create. When lambda expressions are supported, we could do it that way instead (or use MethodHandles).

contextMenuHandler

private final EventHandler<ContextMenuEvent> contextMenuHandler

Constructor Detail

BehaviorSkinBase

protected BehaviorSkinBase(C control,
                           BB behavior)

Constructor for all BehaviorSkinBase instances.

Parameters:

control - The control for which this Skin should attach to.

behavior - The behavior for which this Skin should defer to.

Method Detail

getBehavior

public final BB getBehavior()

dispose

public void dispose()

Called by a Skinnable when the Skin is replaced on the Skinnable. This method allows a Skin to implement any logic necessary to clean up itself after the Skin is no longer needed. It may be used to release native resources. The methods Skin.getSkinnable() and Skin.getNode() should return null following a call to dispose. Calling dispose twice has no effect.

Specified by:

dispose in interface Skin<C extends Control>

Overrides:

dispose in class SkinBase<C extends Control>

registerChangeListener

protected final void registerChangeListener(ObservableValue<?> property,
                                            java.lang.String reference)

Subclasses can invoke this method to register that we want to listen to property change events for the given property.

Parameters:

property -

reference -

unregisterChangeListener

protected final void unregisterChangeListener(ObservableValue<?> property)

Subclasses can invoke this method to unregister listening to property change events for the given property.

Parameters:

property -

handleControlPropertyChanged

protected void handleControlPropertyChanged(java.lang.String propertyReference)

Skin subclasses will override this method to handle changes in corresponding control's properties.
