Help me with KeyListeners pls

[tnt417]

My Problem is that when I press the desired key it just Doesn't trigger
I need some help with this this is my code:

package me.tnt417.main;

import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.applet.Applet;
import java.awt.*;




public class Main extends Applet implements KeyListener {
     /**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private Rectangle rect;
     public void init(){
    	 this.addKeyListener(this);
    	 
    	 rect = new Rectangle(0, 0, 50, 50);

     }
     public void paint(Graphics g){
    	 setSize(500,500);
    	 
     	Graphics2D g2 = (Graphics2D)g;
     	g2.setColor(Color.CYAN);
     	g2.fill (rect);
     	 
      }
     @Override
	public void keyPressed(KeyEvent e) {
		if(e.getKeyCode() == KeyEvent.VK_RIGHT){
			rect.setLocation(rect.x + 2, rect.y);
		}
		else if(e.getKeyCode() == KeyEvent.VK_LEFT){
			rect.setLocation(rect.x - 2, rect.y);
		}
		else if(e.getKeyCode() == KeyEvent.VK_UP){
			rect.setLocation(rect.x, rect.y + 2);
		}
		else if(e.getKeyCode() == KeyEvent.VK_DOWN){
			rect.setLocation(rect.x, rect.y - 2);
			System.out.println("down");
		}
		repaint();
	}

	
	public void keyReleased(KeyEvent e) {
		
		
	}

	
	public void keyTyped(KeyEvent e) {
		
		
	}
}

Define "doesn't work".

the keyListeners dont trigger when i press a key

[Norm]

Also please edit your post and wrap the code in code tags.

[tnt417]

there i did it. is that what u meant?

[tnt417]

sorry a little sloppy

[Norm]

What tags did you use? With code tags, The code should look like this:

   int x = 123; // assign a value to x

[tnt417]

there we go

[Norm]

Ok, that's much better. Does the component with the listener have the focus?

[tnt417]

what do you mean?

[Norm]

See the tutorial: How to Use the Focus Subsystem (The Javaâ„¢ Tutorials > Creating a GUI With JFC/Swing > Using Other Swing Features)

First off Thats too advanced for my level of coding.
Secondly i'm using an Applet

[tnt417]

also i'm using eclipse
and I've seen many tutorials about this which work for them but NOT for me and I even copy the code EXACTLY

[Norm]

Thats too advanced for my level of coding.

You need to understand focus to use keylisteners. The tutorial will give you some background and perhaps some coding ideas.

[tnt417]

you can now mark this as SOLVED I DID IT!!!

[Norm]

Can you explain what you did so anyone having the same problem can read this thread and find a solution?

[tnt417]

I Simply Put this line of code in the init method:

setFocusable(true);

if you were using a JFrame it would be:

//Whatever your JFrame caller is--> frame.setFocusable(true)

Thanks
