CalendarGridPanel, mouse tracking

[tdbear]

It seems to me the component looks nicer if it tracks the mouse movements and is easy to support.
CalendarGridPanel constructor:

 - // addMouseListener(this); 
 + addMouseListener(new MouseAdapter() {
 + public void mouseEntered(MouseEvent e) {
 + requestFocusInWindow();
 + }
 + });
 public void mouseEntered(MouseEvent e) {
 + Component c = e.getComponent();
 + if (c instanceof DateLabel) {
 + try {
 + int day = Integer.parseInt(((DateLabel) c).getText());
 + Calendar cal = Calendar.getInstance();
 + cal.setTime(focusDate);
 + cal.set(Calendar.DAY_OF_MONTH, day);
 + focusDate = cal.getTime();
 + reflectData();
 + } catch (NumberFormatException ex) {}
 + }
 }

The mouseEntered above does the job, but probably there's a simpler version that reads the focusDate directly from DateLabel. Unfortunately, this didn't work for me and I ran out of time do to further exploration. The basic idea would be something like:
// !!!The following impl. does not work because DateLabel.getDate() always returns null !!!

public void mouseEntered(MouseEvent e) {
Component c = e.getComponent();
if (c instanceof DateLabel) {
requestFocusInWindow();
Date d = ((DateLabel) c).getDate();
if (d != null) {
focusDate = d;
reflectData();
}
}
}
