Monitoring AWT Events with the AWTEventListener Class

Monitoring AWT Events with the AWTEventListener Class

The AWTEventListener class’ sole purpose is to view events. All you have to do is to implement the eventDispatched method. The following application demonstrates how:

import java.awt.*;import java.awt.event.*;public class EventTest extends Frame {   public EventTest(String title) {      super(title);   }     void init()   {      setSize(100,100);      setVisible(true);      getToolkit().addAWTEventListener(new AWTEventListener() {         public void eventDispatched(AWTEvent e) {            System.out.println(e+"["+e.getID()+"]");         }},         AWTEvent.KEY_EVENT_MASK | AWTEvent.MOUSE_EVENT_MASK |         AWTEvent.MOUSE_MOTION_EVENT_MASK);   }   public static void main (String args[]) {      EventTest et=new EventTest("Monitoring events:");      et.init();   }}

Note: This application can be used for keyboard and mouse events.
