All Implemented Interfaces:
java.awt.event.ActionListener, java.awt.event.FocusListener, java.awt.event.KeyListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener, javax.accessibility.Accessible, javax.swing.Scrollable, javax.swing.SwingConstants

public class ETextField
extends javax.swing.JTextField
implements java.awt.event.ActionListener, java.awt.event.FocusListener, java.awt.event.KeyListener

FOR INTERNAL USE ONLY.

A customized version of the JTextField. The primary advantage is the ability to install a "ChangeListener", who will be called when the content of the TextField changes (quite similar to the change event with JavaScript). Additionally, it automatically preselects the whole content when activated (to simplify changing).
