- Menu Bar Test Program

This section provides a tutorial example on how to use the javax.swing.JMenuBar class to create a menu bar in a frame window. Menus and menu items added to the menu bar will be listed horizontally.

Here is an example program I wrote to test the JMenuBar class:

 * Copyright (c) 2014,, All Rights Reserved.
import java.awt.event.*;
import javax.swing.*;
public class JMenuBarTest {
   public static void main(String[] a) {
      JFrame f = new JFrame("JMenuBar Test");

      JMenuBar mb = new JMenuBar();      
      mb.add(new JMenu("Tools")); 
      mb.add(new JMenu("Options")); 
      mb.add(new JMenuItem("Save")); 
      mb.add(new JMenuItem("Quit")); 
      mb.add(new JButton("Stop")); 
      f.getContentPane().add(new MyButton());
   private static class MyButton extends JButton 
      implements ActionListener {
      public MyButton() {
      public void actionPerformed(ActionEvent e) {
         System.out.println("Check button clicked");
         JFrame myFrame = (JFrame) 
         JMenuBar myMenuBar = myFrame.getJMenuBar();
         System.out.println("# of elements in the menu bar: "
         System.out.println("Is the menu bar selected: "

If you run this example, you will see the frame window shows up with the menu bar like this:
Menu Bar Test

If you click the "Check" button, click the "Options" menu in the menu bar, and click the "Check" button again, you will see text output in the console window:

Check button clicked
# of elements in the menu bar: 5
Is the menu bar selected: false
Check button clicked
# of elements in the menu bar: 5
Is the menu bar selected: true

Interesting notes about this tutorial example:

Sample programs listed in this section have been tested with JDK 1.6.0 to 1.8.0.
