# WindowAdapter

## Name

WindowAdapter

##

## Description

The `WindowAdapter` class implements the methods of `WindowListener` with empty functions. It may be easier for you to extend `WindowAdapter`, overriding only those methods you are interested in, than to implement `WindowListener` and provide the empty functions yourself.

## Class Definition

    public abstract class java.awt.event.WindowAdapter
       extends java.lang.Object
       implements java.awt.event.WindowListener {
      // Instance Methods

      public void windowClosed (WindowEvent e);
      public void windowClosing (WindowEvent e);
      public void windowDeactivated (WindowEvent e);
