title: How to set JCalendar date in JDateChooser
body: <p>I have a JDateChooser that is used for selecting birth dates. It starts out as null date value and let's the user choose the birth date either using the textfield or the jdatechooser button which opens the Jcalendar.</p>
  
  <p>What I'm trying to do is to set the JCalendar's date to -10 years from the current date. By default, the JCalendar is setting the date at the current year. I tried this code but it doesn't work -- it still sets the date to the current date. Any help will do. Thanks!</p>
  
  <pre><code>    dcBirthDateNew = new JDateChooser();
      dcBirthDateNew.setDateFormatString("MM/dd/yyyy");
      dcBirthDateNew.getDateEditor().getUiComponent().addFocusListener(new FocusAdapter() {
          @Override
          public void focusGained(FocusEvent evt) {
              if (evt.getSource() instanceof JTextComponent) {
                  final JTextComponent textComponent=((JTextComponent)evt.getSource());
                  SwingUtilities.invokeLater(new Runnable(){
                      public void run() {
                          textComponent.selectAll();
                      }});
              }   
          }
      });
      JCalendar calx = dcBirthDateNew.getJCalendar();
      calx.setCalendar(getPrevDate());
  
  private static Calendar getPrevDate() {
      DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");
      Date myDate = new Date(System.currentTimeMillis());
      System.out.println("result is "+ dateFormat.format(myDate));
      Calendar cal = Calendar.getInstance();
      cal.setTime(myDate);
      cal.add(Calendar.YEAR, -10);
      System.out.println(dateFormat.format(cal.getTime()));
      return cal;
  }
  </code></pre>
