All Implemented Interfaces:

Serializable

public class BlockingLayerUI2
extends LayerUI<JComponent>

A JXLayer ui implementation that permits to block a component but still allow an action when clicking everywhere on the layer.

Moreover, an icon can be added on the right-top icon painted and changed when the mouse is over the layer.

You can change the blocking and accepting icon.

To hook an click on the layer's icon, you can :

• pass an Action via method setAcceptAction(Action)
• override the method acceptEvent(MouseEvent, JLayer)
