JMenu ...Can't remember

I can't remember how to get subcategories with JMenu's. If anyone knows how, please let me know. I'll post a screenshot so you know exactly what I'm talking about.

Never mind, I figured it out.

Why don't you post the solution so maybe someone else could find it in the future :)

All you do, is add a JMenu, to a JMenu!
I'll demonstrate below:

Code:

---

JMenuBar menuBar = new JMenuBar();

//Normal menu with no submenu's
JMenu fileMenu = new JMenu("File");
fileMenu.add(new JMenuItem("Exit");

//this will have submenu's
JMenu format = new JMenu("Format");
format.add(new JMenuItem("Font"));

/*  start making the submenu, by creating
 *  a menu, and adding items to it...Once
 *  finished, add the color menu to the format
 *  menu
 */
JMenu color = new JMenu("Color");
color.add(new JMenuItem("Red"));
color.add(new JMenuItem("Blue"));

//add the menu to the other menu
format.add(color);

menuBar.add(fileMenu);
menuBar.add(format);

Yes quite simple.

Code:

---

import java.awt.*;
 import javax.swing.*;
 import java.awt.event.*;

 public class X{
  public static void main(String[] args){

  JFrame jf = new JFrame("JMenu Example");
  Container c = jf.getContentPane();
  JMenuBar jmb = new JMenuBar();
  JMenu jm = new JMenu("File");
  JMenu sendto = new JMenu("Send To");
  JMenuItem print = new JMenuItem("Print");
  JMenuItem exit = new JMenuItem("Exit");
  jf.setJMenuBar(jmb);
  jmb.add(jm);
  jm.add(sendto);
  jm.add(print);
  jm.add(exit);
 
  // add sub menu
  sendto.add(new JMenuItem("3 1/2 Floppy(A)"));
  sendto.add(new JMenuItem("DeskTop"));
  sendto.add(new JMenuItem("Web Publishing Wizard"));
 
  jf.addWindowListener(new WindowAdapter(){
    public void windowClosing(WindowEvent we){
      System.exit(0);
  }
  });
 
  jf.setSize(400,300);
  jf.setVisible(true);

  }
 }
