AWT Button Mouse Click Handler at the Frame Level

This section provides a tutorial example on how to create an AWT button to handle actions by adding the MouseAdapter interface to the frame that contains the button component.

Of course, using ActionListeners is not the only way to handle user clicks on buttons. You can also use MouseListeners to handle user clicks. Here is an example program:

import java.awt.Frame;
import java.awt.Button;
import java.awt.Label;
import java.awt.GridLayout;
import java.awt.event.MouseEvent;
import java.awt.event.MouseAdapter;
public class ButtonAction3 extends MouseAdapter {
   Button myButton = null;
   Label myLabel = null;
   String text = null;
   public static void main(String[] a) {
      ButtonAction3 myTest = new ButtonAction3();
   public void createFrame() {
      Frame f = new Frame("My Switch Button");
      f.setLayout(new GridLayout(2,1));
      text = "On";
      myButton = new Button(text);
      myLabel = new Label(text);
   public void mouseClicked(MouseEvent e) {
      if (text.equals("On")) text = "Off";
      else text = "On"; 

If you run this example, you will get:

AWT Button Mouse Adapter
AWT Button Mouse Adapter

The button works nicely. If you click the button, the button label text will change from "On" to "Off", and the text of the label component will also change.
