Toedter从JDateChooser获取日期

Question

I am using toedter JDateChooser, and I am having problems retrieving the date picked from it.

jDateChooser2.setDateFormatString("dd-MMMM-yy");
jDateChooser2.addMouseListener(new java.awt.event.MouseAdapter() {
    public void mouseClicked(java.awt.event.MouseEvent evt) {
        jDateChooser2MouseClicked(evt);
    }
});

private void jDateChooser2MouseClicked(java.awt.event.MouseEvent evt) {                                           
    Date dateFromDateChooser = jDateChooser2.getDate();
    System.out.println(dateFromDateChooser);
}    

How can I retrieve the date? Is there a better way to do it? I think the listener is not being fired or triggered. i tried replacing the listener with:

    System.out.println("triggered");

Still there are no output.

Basically, you don't want to listener for MouseEvent s, as these could be changing the state of the component in a number of ways, most of which you don't want to know about.

You should be monitoring the date property change event, for example...

JDateChooser dateChooser = new JDateChooser();
dateChooser.addPropertyChangeListener("date", new PropertyChangeListener() {
    @Override
    public void propertyChange(PropertyChangeEvent evt) {
        Date date = (Date)evt.getNewValue();
        System.out.println("Date changed " + date);
    }
});

Just beware, this could be triggered in response to calling setDate or by the user selecting a date from the picker, generally, you won't be able to tell
