Creating a java thread in a jframe class?

Question

hello is this possible to create a thread for a jframe class? so that everytime a connection is established, a new thread along with the gui is opened automaticly? if so, would i just need to insert extends Thread on my declaration of my class?
i already have this code at the top of my jframe class..
public class ChatDialog extends javax.swing.JFrame implements WindowListenerwhere and how would i implement the run() method in thsi class?
full code:
package icomm;
import java.net.*;
import java.io.*;
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
public class ChatDialog extends javax.swing.JFrame implements WindowListener {
    protected String messege;
    private Socket client_user = null;
    /** Creates new form ChatDialog */
    public ChatDialog()
        initComponents();
        addWindowListener( this );
    // <editor-fold defaultstate="collapsed" desc=" Generated Code ">
    private void initComponents() {
        jScrollPane1 = new javax.swing.JScrollPane();
        convo_txt = new javax.swing.JTextArea();
        jScrollPane2 = new javax.swing.JScrollPane();
        txt_messege = new javax.swing.JTextArea();
        send_button = new javax.swing.JButton();
        jMenuBar1 = new javax.swing.JMenuBar();
        jMenu1 = new javax.swing.JMenu();
        Option = new javax.swing.JMenu();
        getContentPane().setLayout(new org.netbeans.lib.awtextra.AbsoluteLayout());
        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
        jScrollPane1.setHorizontalScrollBarPolicy(javax.swing.ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
        jScrollPane1.setViewportView(convo_txt);
        getContentPane().add(jScrollPane1, new org.netbeans.lib.awtextra.AbsoluteConstraints(10, 20, 220, 270));
        jScrollPane2.setHorizontalScrollBarPolicy(javax.swing.ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
        txt_messege.setLineWrap(true);
        jScrollPane2.setViewportView(txt_messege);
        getContentPane().add(jScrollPane2, new org.netbeans.lib.awtextra.AbsoluteConstraints(10, 310, 220, 70));
        send_button.setText("Send");
        send_button.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                send_buttonActionPerformed(evt);
        getContentPane().add(send_button, new org.netbeans.lib.awtextra.AbsoluteConstraints(10, 390, -1, -1));
        jMenu1.setText("File");
        jMenuBar1.add(jMenu1);
        Option.setText("Option");
        jMenuBar1.add(Option);
        setJMenuBar(jMenuBar1);
        pack();
    // </editor-fold>
    private void send_buttonActionPerformed(java.awt.event.ActionEvent evt) {                                           
        //get txt from textbox   
        String text = txt_messege.getText();
    public void windowClosing(WindowEvent e)
        public void windowActivated(WindowEvent e) {}
     public void windowClosed(WindowEvent e) {}
     public void windowDeactivated(WindowEvent e) {}
     public void windowDeiconified(WindowEvent e) {}
     public void windowIconified(WindowEvent e) {}
      public void windowOpened(WindowEvent e)
     * @param args the command line arguments
    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new ChatDialog().setVisible(true);
    // Variables declaration - do not modify
    private javax.swing.JMenu Option;
    private javax.swing.JTextArea convo_txt;
    private javax.swing.JMenu jMenu1;
    private javax.swing.JMenuBar jMenuBar1;
    private javax.swing.JScrollPane jScrollPane1;
    private javax.swing.JScrollPane jScrollPane2;
    private javax.swing.JButton send_button;
    private javax.swing.JTextArea txt_messege;
    // End of variables declaration
}

Answer 1

Instead of attempting to have the frame extend thread (or implement Runnable which is actually possible since you cannot have multiple inferitance). You might want to just create the frame and have that frame lauch an associated thread to take care of the processing required.
