JFrame titleBar resize ?

hi,i got 2 file :

satu.java

import java.awt.BorderLayout;

import java.awt.event.WindowAdapter;

import java.awt.event.WindowEvent;

import javax.swing.JFrame;

publicclass satu{

/**

* @param args

*/

publicstaticvoid main(String[] args){

// TODO Auto-generated method stub

JFrame.setDefaultLookAndFeelDecorated(true);

final JFrame appp =new JFrame("TEST ");

appp.setSize(150,180);

appp.setResizable(false);

dua m =new dua(appp);

m.init();

appp.add(m,BorderLayout.CENTER);

appp.setVisible(true);

//appp.setLocationRelativeTo(null);

appp.addWindowListener(new WindowAdapter(){

publicvoid windowClosing(WindowEvent evt){

appp.setVisible(false);

appp.dispose();

}

});

}

}

dua.java

import java.applet.Applet;

import java.awt.Dimension;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.JButton;

import javax.swing.JFrame;

publicclass duaextends Appletimplements ActionListener{

/**

* @param args

*/

JFrame myframe;

public dua(JFrame sat){

myframe = sat;

}

publicvoid init(){

JButton x =new JButton("Big");

x.addActionListener(this);

add(x);

}

publicvoid actionPerformed(ActionEvent arg0){

// TODO Auto-generated method stub

int newx = myframe.getWidth()+10;

int newy = myframe.getHeight()+10;

myframe.setTitle("X = "+newx+" Y = "+newy);

myframe.setSize(newx,newy);

}

}
