Class RBHighlightHandler

java.lang.Object

java.awt.Component

java.awt.Container

javax.swing.JComponent

edu.mit.blocks.renderable.RBHighlightHandler

All Implemented Interfaces:

java.awt.event.ComponentListener, java.awt.event.HierarchyListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener

public class RBHighlightHandler
extends javax.swing.JComponent
implements java.awt.event.ComponentListener, java.awt.event.HierarchyListener

The RBHighlightHandler class is responsible for maintaining the highlight state of a RenderableBlock and rendering the highlight properly. It works by adding itself to a layer behind its RenderableBlock and drawing the highlight there so as not to cover the block.
