SpinnerDateModel

[Bumsys]

Hello!!! I use JSpinner SpinnerDateModel. And in the begining I want
that the field do not display the date but simple is empty field. How
can I do it?
import java.awt.*;
import java.awt.event.*;
import java.text.ParseException;
import java.text.SimpleDateFormat;

import javax.swing.*;
import javax.swing.event.*;

public class test extends JFrame
// implements WindowListener
{

public static void main(String[] s) {
JFrame frame = new JFrame("Test");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

SpinnerDateModel model = new SpinnerDateModel();
JSpinner dateSpinner = new JSpinner(model);
JSpinner.DateEditor editor = new
JSpinner.DateEditor(dateSpinner,
"dd.MM.yyyy");
dateSpinner.setEditor(editor);
//dateSpinner.addKeyListener(listener);
// editor.addKeyListener(listener); - es passiert nix!
// model.addKeyListener(listener); - hat diese methode nicht

frame.getContentPane().add(dateSpinner);

frame.pack();
frame.setVisible(true);
}

}
