Class Connector

java.lang.Object
  jApp.Connector

All Implemented Interfaces:

java.awt.event.ComponentListener, java.util.EventListener, javax.swing.event.ChangeListener

Direct Known Subclasses:

JComboBoxConnector, JRadioButtonConnector, JTextFieldConnector, JToggleButtonConnector

public class Connector
extends java.lang.Object
implements javax.swing.event.ChangeListener, java.awt.event.ComponentListener

This class connects Variable objects with Component components.

Instances of this class listens to changes in Variable and Component states and pass those changes on. For example when a Component becomes visible attaches the Component to the Variable so that the Component will reflect the value of the Variable and when the Component performs it action sets the value of the Variable accordingly.
