Jcalendar with DateEvaluator

Question

Jcalendar 1.4 with DateEvaluator.

Can i change Border or Font for one field (one day) somehow ?

I need better to distinguish events in the calendar not only change Background and Text Color.

Can i override something on IDateEvaluator?

Deklaration:

 private final Event_01 evaluator_01 = new Event_01();

---

add item to IdateEvaluator

   private void addEvent_01_Calendar(int day, int monht, int year) {
        evaluator_01.add(createDate(day, monht, year));
    }

repaint calendar and add Date Evaluator

  private void repaintEventCalendar() {
                jCalendar.getDayChooser().addDateEvaluator(evaluator_01);
                jCalendar.getDayChooser().addDateEvaluator(evaluator_02);
                jCalendar.getDayChooser().addDateEvaluator(evaluator_03);
                jCalendar.getDayChooser().addDateEvaluator(evaluator_04);
                jCalendar.getDayChooser().addDateEvaluator(evaluator_03_Y);
                jCalendar.getDayChooser().addDateEvaluator(evaluator_03_N);
                jCalendar.setCalendar(jCalendar.getCalendar());
            }

        }
    }

@Override

    return false;

@Override
public Color getInvalidForegroundColor() {
    return null;
}

@Override
public Color getInvalidBackroundColor() {
    return null;
}

@Override
public String getInvalidTooltip() {
    return null;
}

}
