JCheckBoxMenuItemTest.java - Check Box Menu Item Test Program

This section provides a tutorial example on how to use the javax.swing.JCheckBoxMenuItemTest class to create check box menu items. If a check box menu item is selected, its check box icon will have a check sign.

Swing also supports a special menu item class, javax.swing.JCheckBoxMenuItemTest, which represents check box menu items with following special features:

Here is an example program I wrote to test the JCheckBoxMenuItemTest classes:

import javax.swing.*;
public class JCheckBoxMenuItemTest {
   JFrame myFrame = null;
   public static void main(String[] a) {
      (new JCheckBoxMenuItemTest()).test();
   }
   private void test() {
      myFrame = new JFrame("Check Box Menu Item Test");
      myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      myFrame.setBounds(50,50,250,150);
      myFrame.setContentPane(new JDesktopPane());

      JMenuBar myMenuBar = new JMenuBar();
      JMenu myMenu = getFileMenu();
      myMenuBar.add(myMenu);
      myMenu = getColorMenu();
      myMenuBar.add(myMenu);
      myMenu = getOptionMenu();
      myMenuBar.add(myMenu);
      JMenuItem myItem = new JMenuItem("Help");
      myMenuBar.add(myItem);

      myFrame.setJMenuBar(myMenuBar);
      myFrame.setVisible(true);
   }
   private JMenu getFileMenu() {
      JMenu myMenu = new JMenu("File");
      JMenuItem myItem = new JMenuItem("Open");
      myMenu.add(myItem);
      myItem = new JMenuItem("Close");
      myItem.setEnabled(false);
      myMenu.add(myItem);
      myMenu.addSeparator();
      myItem = new JMenuItem("Exit");
      myMenu.add(myItem);
      return myMenu;
   }
   private JMenu getColorMenu() {
      JMenu myMenu = new JMenu("Color");
      JMenuItem myItem = new JMenuItem("Red");
      myMenu.add(myItem);
      myItem = new JMenuItem("Green");
      myMenu.add(myItem);
      myItem = new JMenuItem("Blue");
      myMenu.add(myItem);
      return myMenu;
   }
   private JMenu getOptionMenu() {
      JMenu myMenu = new JMenu("Option");
      JCheckBoxMenuItem myItem = new JCheckBoxMenuItem("Sound");
      myItem.setSelected(true);
      myMenu.add(myItem);
      myItem = new JCheckBoxMenuItem("Auto save");
      myMenu.add(myItem);
      return myMenu;
   }
}

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

Interesting notes about this tutorial example:

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