How to resize window (JFrame) on event

Question

I've got a swing application that uses tabs (JTabbedPane). It's default size is 200,200, and I need to resize the window to different sizes depending on what tab is selected. I can set the default size, but I can't seem to get access to the window to resize it (setBounds/setSize) at runtime.
If anybody can tell me how I can go about this, I would greatly appreciate it.

Here's the code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.event.*;
public class TimeTrack_Example extends JFrame {
     Container cp = getContentPane();
  public static void main(String args[]) {
          TimeTrack_Example TT = new TimeTrack_Example();
          TT.setSize(200,200);
  public TimeTrack_Example() {
          JTabbedPane JTPane = new JTabbedPane();
          JTPane.addChangeListener(cl);
               //Jobs Tab
          JPanel jpJobs = new JPanel();
          JTPane.addTab("Jobs", jpJobs);
               //Timer Tab
          JPanel jpTimer = new JPanel();
          JTPane.addTab("Timers", jpTimer);
               //Report Tab
          JPanel jpReport = new JPanel();
          JTPane.addTab("Report", jpReport);
    cp.add(JTPane);
    addWindowListener(new WindowAdapter() {
        public void windowClosing(WindowEvent e) {System.exit(0);}
    pack();
    show();
          //Tab ChangeListener
     ChangeListener cl = new ChangeListener() { 
          public void stateChanged(ChangeEvent e) {
               int tabID = ((JTabbedPane)e.getSource()).getSelectedIndex();
               if (tabID == 2) {
                    //???               //here's where I need to change the size
}

This is one way:
create a method, lets call it resizeWindow(). Call this method from inside your ChangeListener.
public void resizeWindow() {
this.setSize(300, 400); //whatever values you want
public void stateChange(ChangeEvent e) {
if (tabID == 2) {
resizeWindow();
}
