KeyListener not working....
Hi, I am trying to work out how to use the keylistener to make a character move in the tiled map........(both the java files compile fine but the keylistener is not working)
This is my code for GFrame.java that is calling the GMap.java...
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class GFrame extends JFrame implements KeyListener
{
static Container c ;
static JPanel gamearea = new JPanel();
static GMap gmap = new GMap();
static JFrame f = new GFrame();
public GFrame()
{
gamearea.add(gmap);
c = getContentPane();
c.setLayout(new BorderLayout());
c.add(gamearea, BorderLayout.CENTER);
c.setSize(600, 400);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setTitle("Pirate Game");
pack();
setVisible(true);
setFocusable(true);
gamearea.addKeyListener(this);
addKeyListener(this);
}
public static void main(String args [])
{
f.setVisible(true);
}
public void keyTyped(KeyEvent e) {}
public void keyPressed(KeyEvent e)
{
if(e.getKeyCode() == KeyEvent.VK_UP) {
}
if(e.getKeyCode() == KeyEvent.VK_DOWN) {
}
if(e.getKeyCode() == KeyEvent.VK_LEFT) {
}
if(e.getKeyCode() == KeyEvent.VK_RIGHT) {
}
}
public void keyReleased(KeyEvent e)
{}
}

Can anybody spot what the mistake? Thanks...I really need the answer...
