Class BlockLabel

java.lang.Object

edu.mit.blocks.renderable.BlockLabel

All Implemented Interfaces:

java.awt.event.KeyListener, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.util.EventListener

public class BlockLabel
extends java.lang.Object
implements java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.event.KeyListener

BlockLabel is a region on a block in which text is displayed and possibly edited. The location and font of a BlockLabel is specified in BlockShape and the text displayed is specified by a Block, BlockLabel is the gateway for text to be rendered and modified. The key nature of a BlockLabel is that it is a JLabel when being viewed, and a JTextField when it is being edited. During mouse move, entered and exited events a white border is toggled around the label for particular blocks. This white border helps to suggest editable labels for blocks that have this enabled.
