public class CenterJFrame
extends javax.swing.JFrame
implements java.awt.event.ActionListener, java.awt.event.ItemListener, TreeMessageListener

Center JPanel for use with the TreeApplet. Within this JPanel, the two children panels, TreeJPanel and OptionJPanel are made and all data is stored. Methods called from those two children operate through this JPanel.

Synchronization occurs within this JPanel to ensure no access and modification errors occur.

Each Tree object is maintained in this JPanel.

Parameters:

evt - the String event passed in the optionEvent.

object - the object accompanying the String event type.

optionListener - the specific listener to the event or null if all listeners should be called.
