 * An extension of JLabel which looks like a link and responds appropriately
 * when clicked. Note that this class will only work with Swing 1.1.1 and later.
 * Note that because of the way this class is implemented, getText() will not
 * return correct values, user <code>getNormalText</code> instead.

public class LinkLabel extends JLabel{

   * The normal text set by the user.

  private String text;

   * Creates a new LinkLabel with the given text.

  public LinkLabel(String text){



   * Sets the text of the label.

  public void setText(String text){
    super.setText("<html><font color=\"#0000CF\"><u>"+text+"</u></font></html>"); //$NON-NLS-1$ //$NON-NLS-2$
    this.text = text;

   * Returns the text set by the user.

  public String getNormalText(){
    return text;

   * Processes mouse events and responds to clicks.

  protected void processMouseEvent(MouseEvent evt){
    if (evt.getID() == MouseEvent.MOUSE_CLICKED)
      fireActionPerformed(new ActionEvent(this, ActionEvent.ACTION_PERFORMED, getNormalText()));

   * Adds an ActionListener to the list of listeners receiving notifications
   * when the label is clicked.

  public void addActionListener(ActionListener listener){
    listenerList.add(ActionListener.class, listener);

   * Removes the given ActionListener from the list of listeners receiving
   * notifications when the label is clicked.

  public void removeActionListener(ActionListener listener){
    listenerList.remove(ActionListener.class, listener);

   * Fires an ActionEvent to all interested listeners.

  protected void fireActionPerformed(ActionEvent evt){
    Object [] listeners = listenerList.getListenerList();
    for (int i = 0; i < listeners.length; i += 2){
      if (listeners[i] == ActionListener.class){
        ActionListener listener = (ActionListener)listeners[i+1];
