java - How to show only date after the date of today in JCalendar

Question

i'm trying to limit user to select only the date after today, or select date after another Date I see on JCalendar API something that could help me but i didn't find nothing.. how can i do it?

Answer 1

I do not think there is a straight forward way on the component to do this. One way, that I know of is to use the setSelectableDateRange(Date from,Date to) - When you set the from date to current date, all previous day cells, year/month drop downs becomes disabled.

Example:

    JCalendar calendar = new JCalendar();
    calendar.setSelectableDateRange(new Date(),new SimpleDateFormat("MM-DD-YYYY").parse("05-05-2015"));

    PropertyChangeListener calendarChangeListener  = new PropertyChangeListener() {
        @Override
        public void propertyChange(PropertyChangeEvent evt) {
            Date selectedDate = ((JCalendar)evt.getSource()).getDate();
        }
    };
    calendar.addPropertyChangeListener("calendar",calendarChangeListener);

This will disable selection of any date before current date and after 05/05/2015

Note that this API is not documented in their javadoc. But still this is a public setter that works as expected.

EDIT since you want to know how JDateChooser can be used in similar context

    JDateChooser chooser = new JDateChooser();
    chooser.getJCalendar().setSelectableDateRange(new Date(),new SimpleDateFormat("MM-DD-YYYY").parse("05-05-2015"));
    chooser.getJCalendar().addPropertyChangeListener("calendar",...);
