[SOLVED] Disable dates JDates Chooser

Disable dates JDates Chooser

I'm newbie and I want to disable dates like shown in this example but in a JDateChooser button. Here is my code and hope you guys can help me.

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");

RangeEvaluator evaluator = new RangeEvaluator();
evaluator.setStartDate(dateFormat.parse("2013-09-14"));
evaluator.setEndDate(dateFormat.parse("2013-09-23"));


JDateChooser calendar = new JDateChooser();
calendar.getCalendar.(evaluator);
// evaluator must be added to a JDayChooser object 

calendar.setSize(180, 25); 
calendar.setLocation(140, 640);
calendar.setVisible(true);
calendar.updateUI();
this.add(calendar);

Solution

Let's start with your question: How to add an IDateEvaluator to a JDateChooser? This is a really easy-to-solve problem but you must know the API first:

JDayChooser is a panel with buttons for each day of a month displayed in a tabular form.
JCalendar component has a JDayChooser embedded and adds the ability to change the year and month, updating the day chooser.
JDateChooser displays a JCalendar in a popup when you press the selector button.

So you basically need to get the reference to the JDayChooser component and add the date evaluator like this:

RangeEvaluator evaluator = new RangeEvaluator();
...
JDateChooser dataChooser = new JDateChooser();
dateChooser.getJCalendar().getDayChooser().addDateEvaluator(evaluator);

Other comments

Be aware of the buggy behavior described in this answer. You should set the current date explicitely after adding date evaluators to solve this issue.
You should never call any updateUI() method explicitely. It is intended to reset the UI property of a component to a value from the current Look and Feel.
Be aware that methods such as setSize(...), setLocation(...) or setBounds(...) are discouraged because Swing is not designed to be used with exact components size/location but with Layout Managers instead. See also this topic.
