Help for a labyrinth program

Question

hello everyone!
i need some help for my program, i've just begun java and i'm creating a labyrinth program for a school project.
it's far from being finished, but my main problem right now is the KeyListener....
i'd like to create a new Labyrinthe class when i use the arrow keys to make sure it works.
please help me and correct me, here's my program:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Labyrinthe extends JFrame implements MouseListener, KeyListener{
     public static void main(String args[]) {
        new Labyrinthe();
     JPanel p1 = new JPanel();
     JPanel p2 = new JPanel();
     JPanel p3 = new JPanel();
     JPanel p4 = new JPanel();
     JButton sauv = new JButton ("sauvegarder");
     JButton q = new JButton("quitter");
     JButton newW = new JButton("nouveau");
     JButton closeW = new JButton("fermer");
     JButton dirh = new JButton("haut");
     JButton dirb = new JButton("bas");
     JButton dird = new JButton("droite");
     JButton dirg = new JButton("gauche");
     public Labyrinthe() {
        setLayout(new BorderLayout());
        Label l = new Label("Labyrinthe");
        Label l2 = new Label("Options");
        Label l3 = new Label("Directions");
        add(p1,BorderLayout.NORTH);
        add(p2,BorderLayout.SOUTH);
        add(p3,BorderLayout.WEST);
        add(p4,BorderLayout.CENTER);
        p1.add(l2);
        p1.add(q); p1.add(newW); p1.add(closeW); p1.add(sauv);
        p2.add(l3);
        p2.add(dirh);p2.add(dirb);p2.add(dird);p2.add(dirg);
        p3.add(l);
        p4.setBackground(Color.cyan);
        setTitle("Labyrinthe");
        setSize(400,400);
        setVisible(true);
        sauv.addMouseListener(this);
        q.addMouseListener(this);
        newW.addMouseListener(this);
        closeW.addMouseListener(this);
        dirh.addMouseListener(this);
          dirb.addMouseListener(this);
          dird.addMouseListener(this);
          dirg.addMouseListener(this);
          addKeyListener(this);
          addWindowListener(new WindowAdapter(){
               public void windowClosing(WindowEvent evt){
                    System.exit(0);
     public void mouseClicked(MouseEvent e) {
        Object s = e.getSource();
        if(s instanceof JButton) {
                if((JButton)s == q) // quit
                        System.exit(0);
                if((JButton)s == newW) // nouveau
                        new Labyrinthe();
                if((JButton)s == closeW) // fermer
                        this.dispose();
                if((JButton)s == dirh)
                     new Labyrinthe();
                if((JButton)s == dirb)
                     new Labyrinthe();
                if((JButton)s == dirg)
                     new Labyrinthe();
                if((JButton)s == dird)
                     new Labyrinthe();
     public void mouseEntered(MouseEvent e) {
     public void mouseExited(MouseEvent e) {
     public void mousePressed(MouseEvent e) {
     public void mouseReleased(MouseEvent e) {
     public void keyPressed (KeyEvent k) {
          if (k.getKeyCode() == KeyEvent.VK_UP){
               new Labyrinthe();
          if (k.getKeyCode() == KeyEvent.VK_DOWN){
               new Labyrinthe();
          if (k.getKeyCode() == KeyEvent.VK_LEFT){
               new Labyrinthe();
          if (k.getKeyCode() == KeyEvent.VK_RIGHT){
               new Labyrinthe();
     public void keyReleased (KeyEvent k) {
     public void keyTyped (KeyEvent k) {
}thx again for your help

Answer 1

You only get key events if you have input focus; as you have it, one of the buttons has focus.
Either
- add mouse and key listener to p4, and have p4 request the focus on initialisation or when you click on it,
Or
- create AbstractActions for your movement commands which call methods which carry out the commands, and set the keyboard shortcut for them to the approriate keys.
