KeyListener for a JFrame

Question

I searched through this forum trying to figure out how to make a KeyListener work for an entire JFrame, but could not understand the answers all you java experts out there gave... Could someone please simplify it for me by explaining your code instead of just typing it in and saying "that's how you do it"? Because I really didn't get what to do. I have a class that implements a KeyListener and extends the JFrame I want the KeyListener for. I tried a simple "addKeyListener(this)" but the events for the Listener were never triggered. I would be very thankful for any and all responses given.

Answer 1

The following simple program
import javax.swing.*;
import java.awt.event.*;
public class KeyListenerTest {
     public static void main(String[] args) {
          KeyListenerFrame frame = new KeyListenerFrame();
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          frame.addKeyListener(frame);
          frame.show();
class KeyListenerFrame extends JFrame implements KeyListener {
     public void keyPressed(KeyEvent evt) {
          System.out.println("keyPressed");
     public void keyReleased(KeyEvent evt) {
          System.out.println("keyReleased");
     public void keyTyped(KeyEvent evt) {
          System.out.println("keyTyped");
}opens a JFrame which triggers all of the three handled events whenever a key is pressed on the keyboard.
I am not sure whether this is could be an answer to your problem or rather I missed the point...
Bye
