如何制作多文档界面？

Question

我在netbeans平台下面开发GUI程序，我能不能开发出多文档界面（VB当中称为MDI），如果行的话，窗体之间如何进行数据交换，例如：一个窗体当中的文本框的内容赋值给另外一个窗体？

如果要使用JInternalFrame好像要先用JdesktopPane吧。
    private void isHangBan(String title) {
        superviseframes.jdesktoppane.add(JIF =
                new HangBanInfo(title, superviseframes.dataread));
        JIF.setSize(superviseframes.jdesktoppane.getSize());
        JIF.setVisible(true);
    }

使用JDesktopPane和JInternalFrame
package test;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import javax.swing.*;public class InternalFrameLXX {
  public static void main(String[] arg)
  {
      JFrame  frame=new FrameLXX();
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.setVisible(true);
   }}
class FrameLXX extends JFrame{
   JDesktopPane desktoppane;
   JInternalFrame jinternalframe;
   JMenuBar jmenubar;
   JMenu jmenu;
   JMenuItem jmenuitem;
    public FrameLXX()
       {
           this.setSize(1000,1000);
           jmenubar=new JMenuBar();
           jmenu=new JMenu("GOD LXX");
           jmenuitem=new JMenuItem("NEW LXX");
           jmenuitem.addActionListener(new ActionListener()
           {
               public void actionPerformed(ActionEvent event)
               {
                   System.out.println("hahah ");
                   jinternalframe=new JInternalFrame("Angel LXX",
                                  true,
                                  true,
                                  true,
                                  false         );
                   jinternalframe.add(new JLabel("sdada"),BorderLayout.CENTER);
                   jinternalframe.reshape(300,300,150,150);
                   jinternalframe.setVisible(true);
                  desktoppane.add(jinternalframe,BorderLayout.CENTER);
               }
           });
           jmenu.add(jmenuitem);
           jmenubar.add(jmenu);
           setJMenuBar(jmenubar);
           desktoppane=new JDesktopPane();
           add(desktoppane,BorderLayout.CENTER);       }
}
