Class ViewScreen

java.lang.Object
  java.awt.Component
      java.awt.Container
          javax.swing.JComponent
              sudoku.ViewScreen

All Implemented Interfaces:

java.awt.event.FocusListener, java.awt.event.MouseListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener

public class ViewScreen
extends javax.swing.JComponent
implements java.awt.event.FocusListener, java.awt.event.MouseListener

Component that displays the playing field. This is actually the most difficult part of the design, so I took lots of it from the 68HCS12 simulator code!
