A program I'm writing allows users to click a date on a JXDatePicker to set the date a task has been completed. I would like to disable the selection of future dates in the JXDatePicker, since in my program selecting future dates is invalid.
I have found that JXDatePickers contain a JXMonthView, and it does not seem that date pickers or month views allow you to disable individual/ranges of dates. I can change the background coloring of individual dates and ranges of dates, which should allow me to make future dates a separate color. Then I could add in some validation whenever the user clicks the calendar to disallow future dates. However, it would be so much cleaner if I could just say something like calendar.setMaxDate(today);
Does anyone know if there is an easier method of doing this than hand-coding the functionality? Perhaps another date picker component fixes this problem?
If you want to restrict date selection to only a range, you can specify upper and lower boundries
JXDatePicker picker = new JXDatePicker();
Calendar calendar = picker.getMonthView().getCalendar();
// starting today if we are in a hurry
calendar.setTime(new Date());
picker.getMonthView().setLowerBound(calendar.getTime());
// end of next week
CalendarUtils.endOfWeek(calendar);
calendar.add(Calendar.WEEK_OF_YEAR);
picker.getMonthView().setUpperBound(calendar.getTime());
(Taken from the JavaDocs)
This will basically restrict the valid, selectable dates from today to the end of the week.
