Thread: Key Listener not working in jinternalframe

hi all

i made a jinternalframe and registered keylistener when a key is pressed it should print the
key code but it doesnot print the key code. please tell me what is wrong my code is given below
===================

import javax.swing.*;
import java.awt.*;
import javax.swing.table.* ;
import java.util.*;
import java.sql.*;
import java.awt.event.*;


public class AddContractor extends JInternalFrame implements KeyListener
{

public AddContractor()
{
super("|Contractor|" , true , true , true , true);
try{
setSize(463 , 450);
setLocation(260 , 140);
jbInit();

}catch(Exception e)
{
e.printStackTrace();
}
} //close of addproject const


private void jbInit() throws Exception


{


this.getContentPane().setLayout(null);
this.getContentPane().setBackground(new Color(71, 97, 142));
addKeyListener(this);
this.setVisible(true);

}


public void keyPressed(KeyEvent ke)
{
System.out.print(ke.getKeyCode());
}

public void keyReleased(KeyEvent kre){

System.out.println(kre.getKeyCode() );

}

public void keyTyped(KeyEvent kety){

System.out.println(kety.getKeyCode() );

}






}

From the code you posted and without having a self contained runnable example its debug. In many cases keyListeners do not work on components because that particular component does not have focus (eg try calling requestFocus)
