I am working with a Java Swing GUI.  I have a JMenuBar on the main JFrame with JMenus and JMenuItems.  Directly below this menu bar I have a JTabbedPane.  When I expand the menus in the Main Menu the bottom menu items disappear behind the JTabbedPane when the first tab in the JTabbedPane is selected.  When the second tab in the JTabbedPane is selected everything is fine.  How do I fix this?

Thanks,
Dave

Example code:

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

public class TabMenuExample extends JFrame
{
    public TabMenuExample()
    {
        this.setJMenuBar(CreateMenuBar());
        getContentPane().add(CreateTabbedPane());
        this.setSize(800,600);
        this.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
    }

    public JTabbedPane CreateTabbedPane()
    {
        JTabbedPane tab = new JTabbedPane();

        for(int i=0;i<10;i++)
        {
            JPanel pnl = new JPanel();
            tab.addTab("Tab" + i, null, pnl, "Tab" + i);
        }
        tab.setSelectedIndex(0);
        return tab;
    }

    public JMenuBar CreateMenuBar()
    {
        JMenuBar menubar = new JMenuBar();
        JMenu menu = new JMenu("Testing Menus");

        for(int i=0;i<10;i++)
        {
            JMenuItem menuitem = new JMenuItem("Menu Items " + i);
            menu.add(menuitem);
        }
        menubar.add(menu);
        return menubar;

    }

    public static void main(String[] args)
    {
        TabMenuExample test = new TabMenuExample();
        test.setVisible(true);
    }
}

Works for me, using java version 1.5.0_09.

The problem is that you are mixing awt (heavy weight) and swing (light weight) components and that heavies win the competition and stay on top

hoomany,
   I think you are correct we are using a GOTS product that I believe has AWT components.  I emailed the developers today to confirm this.  I'll check back tomorrow if my assumption is correct.
