This Java Swing tip illustrates a method of implementing a label that does not give any indication it has been clicked. This is an extension of the JLabel class that listens to mouse clicks and converts them to ActionEvents, which in turn are reported via an EventListenersList object.

public class SecretLabel extends JLabel {
    
    public SecretLabel(String msg) {
        
        super(msg);
        
        addMouseListener(new MouseAdapter() {
            public void mouseClicked(MouseEvent me) {
                fireActionPerformed(new ActionEvent(SecretLabel.this,
                        ActionEvent.ACTION_PERFORMED,
                        "SecretMessage"));
            }
        });
    }
    
    public void addActionListener(ActionListener l) {
        // We'll just use the listenerList we inherit from JComponent.
        listenerList.add(ActionListener.class, l);
    }
    
    public void removeActionListener(ActionListener l) {
        listenerList.remove(ActionListener.class, l);
    }
    
    protected void fireActionPerformed(ActionEvent ae) {
        
        Object[] listeners = listenerList.getListeners(ActionListener.class);
        
        for (int i = 0; i < listeners.length; i++) {
            ((ActionListener)listeners[i]).actionPerformed(ae);
        }
    }
