public class BlockingLayerUI
extends org.jdesktop.jxlayer.plaf.AbstractLayerUI<JComponent>

A JXLayer ui implementation that permits to block a component but still allow an action when clicking on the right-top icon painted on 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, JXLayer)

1.2
