keyPressed method not working?

[TP-Oreilly]

Hi, I have this code:

public void keyPressed(KeyEvent e){
 
			int keyCode = e.getKeyCode();
			if (keyCode == KeyEvent.VK_ESCAPE){
 
				System.exit(0);
 
			}
 
		}

But I am getting "illegal start of expression" and "';' expected" errors, I guess I am doing something wrong?

I have implemented the KeyListener class.

You're going to have to supply an SSCCE that demonstrates the error- it could be that the source of your problem is in another piece of code (probably a missing bracket or parenthesis). Boil it down to as small a piece of code that still exhibits that behavior, and we'll go from there.

This is my code, it is only small:

import java.awt.*;
import javax.swing.*; 
import java.awt.event.*;
 
class MoveIcon implements KeyListener{
 
	public static void main(String[]args){
		//create window
		JFrame frame = new JFrame("Moving Icon App");
		frame.setSize(600,400);
		frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE);
 
		JPanel background = new JPanel();
		background.setOpaque(true);
 
		frame.setContentPane(background);
		frame.setLayout(null);
 
		ImageIcon icon = new ImageIcon("dot.jpg");
 
 
		JLabel label = new JLabel(icon);
		label.setSize(label.getPreferredSize());
		label.setLocation(100,50);
 
 
		Container windowsContentPane = frame.getContentPane();
 
		windowsContentPane.add(label);
 
 
		frame.setVisible(true);
 
		public void keyPressed(KeyEvent e){
 
			int keyCode = e.getKeyCode();
			if (keyCode == KeyEvent.VK_ESCAPE){
 
				System.exit(0);
 
			}
 
		}
 
 
 
 
	}
 
 
 
 
 
}

Thanks

Ah, I see. Your keyPressed() method seems to be inside your main() method, which is not allowed. You could have an anonymous inner class, but I don't think that's what you're going for, since you implemented KeyListener.

Ah thank you, ive now got it to compile but it doesnt work.

I have to defined all of the methods of the KeyListener interface. I have removed the "if (keyCode == KeyEvent.VK_ESCAPE){" and just put in "System.out.print("hi");", I also tried "System.exit(0);", but nothing happens. Ideas?

When do you add the KeyListener? Recommended reading: How to Write a Key Listener (The Java™ Tutorials > Creating a GUI With JFC/Swing > Writing Event Listeners)
