multiple views in swing(urgent help needed)

[PMP Kannan]

hi,
i am trying to get multiple views of a Jpanel ( which has some components like label , textfield etc.,)which is added to a JFrame. i tried using cloning technique and i got the clonable part of the JPanel but the cloned part is not editable. it's locked. could anyone tell me how a component can be viewed in multiple editors at the same time and changes made in one editor will be reflected in all editors. Each view is identical to the others.
( for example in NETBEANS IDE we have this functionality) in the java editor of NetBeans IDE if we click clone view u get a new frame with the same contents and changes made in the cloned view is reflected in the main editor and vice versa.
some one pls do help me.( urgent)
thanks in advance
the code i tried to use using clonable interface is given below.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class CloneFrame extends JFrame implements ActionListener {
CloneTest cloneTest = null;
CloneTest cloneTes = null;
JButton button = null;
public CloneFrame() {
cloneTest = new CloneTest();
button = new JButton("Save");
this.getContentPane().setLayout(new BorderLayout());
this.getContentPane().add(cloneTest, "Center");
this.getContentPane().add(button, "South");
button.addActionListener( this );

this.setSize(200,200);
this.setVisible(true);
}
public void actionPerformed(ActionEvent ae) {
CloneTest cl2 = (CloneTest)cloneTest.clone();
JFrame frm2 = new JFrame();
frm2.getContentPane().setLayout( new BorderLayout() );
frm2.setSize(100,30);
frm2.getContentPane().add(cl2, "North");
frm2.setVisible(true);
}
public static void main(String ar[]) {
new CloneFrame();
}
}
class CloneTest extends JPanel implements Cloneable {
JButton jb;
JTextField jt;
public CloneTest() {
jb = new JButton("hello");
jt = new JTextField("hello world");
add(jb);
add(jt);
}

public Object clone() {
try {
return super.clone();
}
catch (CloneNotSupportedException e) {
throw new InternalError(e.toString());
}
}
}

cheers

I'm not sure why clone does that... there may be some way to work around it, but here's some code illustrating what you want to happen:

import javax.swing.*; 
import java.awt.*;
import java.awt.event.*;
 
public class CloneFrame extends JFrame implements ActionListener {
    CloneTest orig = null;
    CloneTest clone = null;
    JButton button = null;
    
    public CloneFrame() {
        orig = new CloneTest();
        button = new JButton("Save"); 
        
        this.getContentPane().setLayout(new BorderLayout());
        this.getContentPane().add(orig, "Center");
        this.getContentPane().add(button, "South");
        button.addActionListener( this );
        
        this.setSize(200,200);
        this.setVisible(true);
    }
    
    public void actionPerformed(ActionEvent ae) {
        CloneTest cl2 = (CloneTest)orig.clone();
        JFrame frm2 = new JFrame();
        frm2.getContentPane().setLayout( new BorderLayout() );
        frm2.setSize(200, 200);
        frm2.getContentPane().add(cl2, "North");
        frm2.setVisible(true);
    }
    
    public static void main(String ar[]) { 
        new CloneFrame();
    }
    
}
 
class CloneTest extends JPanel {
    JButton jb1, jb2;
    JTextField jt1, jt2;
    
    public CloneTest() {
        jb1 = new JButton("hello");
        jb2 = new JButton();
        jb2.setModel( jb1.getModel() );
        jb2.setText( jb1.getText() );
        jt1 = new JTextField("hello world");
        jt2 = new JTextField();
        jt2.setDocument( jt1.getDocument() );
        add(jb1);
        add(jt1);
        add( jt2 );
        add( jb2 );
    }
    
    public Object clone() {
        CloneTest p = new CloneTest();
        p.jb1.setModel( jb1.getModel() );
        p.jb2.setModel( jb2.getModel() );
        p.jt1.setDocument( jt1.getDocument() );
        p.jt2.setDocument( jt2.getDocument() );
        return p;
    }
    
}

Thanks! and welcome to the JavaRanch!
