Anyone know why this doesn't work?

Question

Hi,
I am trying to work with layeredPane's, and I am having a bit trouble, Here is my modified code of a java tutorial:
package org;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
* LayeredPaneDemo.java is a 1.4 application that requires
* images/dukeWaveRed.gif.
public class LayeredPaneDemo extends JPanel {
    private String[] layerStrings = { "Yellow (0)", "Magenta (1)",
                                      "Cyan (2)",   "Red (3)",
                                      "Green (4)" };
    private Color[] layerColors = { Color.yellow, Color.magenta,
                                    Color.cyan,   Color.red,
                                    Color.green };
     private Label[] layeredLabels = new Label[5];
    private JLayeredPane layeredPane;
    public LayeredPaneDemo()    {
        setLayout(new BoxLayout(this, BoxLayout.PAGE_AXIS));
        //Create and set up the layered pane.
        layeredPane = new JLayeredPane();
        layeredPane.setPreferredSize(new Dimension(300, 310));
          for (int i = 0; i < layerStrings.length; i++) {
            layeredLabels[i] = createColoredLabel(layerStrings, layerColors[i] );
     layeredLabels[i].addMouseListener(mouseListener);
     setupLayers();
add(layeredPane);
     private MouseListener mouseListener = new MouseAdapter() {
          public void MouseClicked(MouseEvent e) {     System.err.println("clicked");
               Label label = (Label) e.getSource();
               label.setUp();
               setupLayers();
               layeredPane.validate();
               layeredPane.repaint();
     private void setupLayers() {
//This is the origin of the first label added.
Point origin = new Point(10, 20);
//This is the offset for computing the origin for the next label.
int offset = 35;
          //Add several overlapping, colored labels to the layered pane
//using absolute positioning/sizing.
          for(int x=0; x< layeredLabels.length; x++) {
               Label label = layeredLabels[x];
     if(label.up) {
origin.y += offset;
label.setBounds(origin.x, origin.y, 100, 100);
layeredPane.add(label, new Integer(x));
origin.x += offset;
               if(label.up) {
origin.y -= offset;
//Create and set up a colored label.
private Label createColoredLabel(String text, Color color) {
Label label = new Label(text);
label.setVerticalAlignment(JLabel.TOP);
label.setHorizontalAlignment(JLabel.CENTER);
label.setOpaque(true);
label.setBackground(color);
label.setForeground(Color.black);
label.setBorder(BorderFactory.createLineBorder(Color.black));
return label;
* Create the GUI and show it. For thread safety,
* this method should be invoked from the
* event-dispatching thread.
private static void createAndShowGUI() {
//Make sure we have nice window decorations.
JFrame.setDefaultLookAndFeelDecorated(true);
//Create and set up the window.
JFrame frame = new JFrame("LayeredPaneDemo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//Create and set up the content pane.
JComponent newContentPane = new LayeredPaneDemo();
newContentPane.setOpaque(true); //content panes must be opaque
frame.setContentPane(newContentPane);
//Display the window.
frame.pack();
frame.setVisible(true);
public static void main(String[] args) {
//Schedule a job for the event-dispatching thread:
//creating and showing this application's GUI.
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
     class Label extends JLabel {
          public boolean up = false;
          public Label(String text) {
               super(text);
          public void setUp() { up = !up; }
for some reason the mouse listener isn't responding, and i don't know why..
Thats only part of my problem. When the mouse listener does respond, I want to only move one of the labels in the Y direction, and then re-paint everything...
any ideas?

Answer 1

public void MouseClicked(MouseEvent e) {     System.err.println("clicked");should be small m
public void mouseClicked(MouseEvent e) {     System.err.println("clicked");
