i want to lunch an internal frame from an menu item,but when i lunch it from main frame,the main frame's content becomes invisble,can any one tell
me,how can i make main frame's content's visble even after internal frame has been lunched from main frame,here is the code i wrote

[import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
public class internalframe extends JFrame
JMenuBar bar;
JMenu m1,m2,m3,m4;

public internalframe()

super("internal frame demo");

bar=new JMenuBar();
m1=new JMenu("launch inernal frame");
JMenuItem ie=new JMenuItem("open frame");
Container c1=getContentPane();


//anonymos classes
ie.addActionListener(new ActionListener( ) {
public void actionPerformed(ActionEvent e)

JDesktopPane d1=new JDesktopPane();

JInternalFrame i1=new JInternalFrame("my experiments",true,true,true,true);

i1.setLayout(new FlowLayout());


public static void main(String args[])

I noticed you are creating the JDesktopPane in the listener. I would think you would want to create it and add it to the JFrame's content pane when initializing the frame. Maybe that would help.

can any body modify the code to display the main frame's components after the internalframe is lunched
Tick check! Okay, I guess that was just an itch. Oh wait! Just a tiny ad:
