Combine two different JPopupmenu

My code below displays only the menu item from pop2. Any idea ?

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JMenuItem;
import javax.swing.JPanel;
import javax.swing.JPopupMenu;
import javax.swing.border.BevelBorder;
import javax.swing.event.PopupMenuEvent;
import javax.swing.event.PopupMenuListener;

public class PopupMenuExample extends JPanel {

/**
     * 
     */
private static final long serialVersionUID = 1L;
public JPopupMenu popup;
public JPopupMenu popup2;
public JPopupMenu test;
public JPopupMenu test3;
  @SuppressWarnings("unqualified-field-access")
public PopupMenuExample() {
    popup = new JPopupMenu();
    popup2 = new JPopupMenu(); 
    ActionListener menuListener = new ActionListener() {
      public void actionPerformed(ActionEvent event) {
        System.out.println("Popup menu item ["
            + event.getActionCommand() + "] was pressed.");
      }
    };
    JMenuItem item;

popup.add(item = new JMenuItem("Left", new ImageIcon("1.gif")));
    item.setHorizontalTextPosition(JMenuItem.RIGHT);
    item.addActionListener(menuListener);
    popup.add(item = new JMenuItem("Center", new ImageIcon("2.gif")));
    item.setHorizontalTextPosition(JMenuItem.RIGHT);
    item.addActionListener(menuListener);
    popup.add(item = new JMenuItem("Right", new ImageIcon("3.gif")));
    item.setHorizontalTextPosition(JMenuItem.RIGHT);
    item.addActionListener(menuListener);
    popup.add(item = new JMenuItem("Full", new ImageIcon("4.gif")));
    item.setHorizontalTextPosition(JMenuItem.RIGHT);
    item.addActionListener(menuListener);
    popup.addSeparator();
    popup.add(item = new JMenuItem("Settings . . ."));
    item.addActionListener(menuListener);
    popup2.add(item = new JMenuItem("Settings . . 2"));
    test = (JPopupMenu)popup.add(popup2);    
    popup.setLabel("Justification");
    popup.setBorder(new BevelBorder(BevelBorder.RAISED));
    popup.addPopupMenuListener(new PopupPrintListener());
    addMouseListener(new MousePopupListener());
  }

// An inner class to check whether mouse events are the popup trigger
  class MousePopupListener extends MouseAdapter {
    public void mousePressed(MouseEvent e) {
      checkPopup(e);
    }

public void mouseClicked(MouseEvent e) {
      checkPopup(e);
    }

public void mouseReleased(MouseEvent e) {
      checkPopup(e);
    }

private void checkPopup(MouseEvent e) {
      if (e.isPopupTrigger()) {
        PopupMenuExample.this.test.show(PopupMenuExample.this, e.getX(), e.getY());          
       //popup.show(PopupMenuExample.this, e.getX(), e.getY());
      }
    }
  }

// An inner class to show when popup events occur
  class PopupPrintListener implements PopupMenuListener {
    public void popupMenuWillBecomeVisible(PopupMenuEvent e) {
      System.out.println("Popup menu will be visible!");
    }

public void popupMenuWillBecomeInvisible(PopupMenuEvent e) {
      System.out.println("Popup menu will be invisible!");
    }

public void popupMenuCanceled(PopupMenuEvent e) {
      System.out.println("Popup menu is hidden!");
    }
  }

public static void main(String s[]) {
    JFrame frame = new JFrame("Popup Menu Example");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setContentPane(new PopupMenuExample());
    frame.setSize(300, 300);
    frame.setVisible(true);
  }
}

Because you're showing the test popup menu which is the same as popup2.

What you're trying to do won't work. You're adding popup2 to popup as a component, not as an extension of the menu items.

Thanks
Is there a way to add as popup2 as a popupmenu to popup

If so let me know

Maybe a "sub menu" is all you need. Read the section from the Swing tutorial on How to Use Menus.

thanks
