Trouble getting Keyboard input with KeyListener

[mrjohn]

Hey, I'm trying to make a program that will recognize when certain keys are released, so that I can encorperate it into a game I'm making. Unfortunately, it doesn't seem to be working. When I run the program and press keys, nothing happens. Any ideas?

[code="java"]import java.awt.Dimens ion;
import java.awt.Graphi cs;
import java.awt.Graphi cs2D;
import java.awt.Image;
import java.awt.event. KeyEvent;
import java.awt.event. KeyListener;

import javax.swing.Ima geIcon;
import javax.swing.JFr ame;
import javax.swing.JPa nel;

@SuppressWarnin gs("serial")
public class lab extends JPanel implements KeyListener
{

Image tiles;
Dimension size;

public lab()
{
addKeyListener( this);
requestFocus();
size = new Dimension();
tiles = new ImageIcon(this. getClass().getR esource("../stars.png")).ge tImage();
size.width = tiles.getWidth( null);
size.height = tiles.getHeight (null);
setPreferredSiz e(size);
}
public void paint(Graphics g) {

Graphics2D g2d = (Graphics2D) g;

g2d.drawImage(t iles, 0, 0, null);
}

public void keyReleased(Key Event e)
{
System.out.prin tln("TEST");
if(e.getKeyCode () == KeyEvent.VK_UP)
{
System.out.prin tln("UP");
}
else
{
System.out.prin tln(e.getKeyCha r());
}
}

public static void main(String[] args) {

JFrame frame = new JFrame("Test");
frame.add(new lab());
frame.setDefaul tCloseOperation (JFrame.EXIT_ON _CLOSE);
frame.pack();
frame.setLocati onRelativeTo(nu ll);
frame.setVisibl e(true);
}
@Override
public void keyPressed(KeyE vent e)
{
System.out.prin tln("KEY PRESSED");
}
@Override
public void keyTyped(KeyEve nt e)
{
System.out.prin tln("KEY TYPED");
}
}[/code]

I know its frustrating, it seems that you can not set form on focus;
anyway
I had the same problem and i found a simple solution(not sure if the best solution lol)
You can use textfield and listen to his key listener!
its simple and it works!
u dont have to change much in fact u need to ad textfield
set it to:
textfield.setvi sible(false) and textfield.reque stfocus()

Ah... well, after some monkeying around and looking at examples on the web, I found the solution. I'm sorry, I probably should have posted it on this thread when I found it.

To fix it, all I had to do was replace line #52 with something like the following code:
[CODE="java"]
lab l = new lab();
frame.addKeyLis tener(l);
frame.add(l);[/CODE]
