/**
* A component for entering dates with a user interaction similar to a
* JComboBox. The dates can be typed into a text field or selected from a
* JXMonthView which opens in a JXPopupMenu on user's request.
*
*
* The date selection is controlled by the JXMonthView's DateSelectionModel.
* This allows the use of all its functionality in the JXDatePicker as well.
* F.i. restrict the selection to a date in the current or next week:
*
*
*
* Appointment appointment = new Appointment(director,
* "Be sure to have polished shoes!");
* 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());
*
*
* Similar to a JXMonthView, the JXDatePicker fires an ActionEvent when the user
* actively commits or cancels a selection. Interested client code can add a
* ActionListener to be notified by the user action.
*
*
* JXDatePicker picker = new JXDatePicker(new Date());
* ActionListener l = new ActionListener() {
* public void actionPerformed(ActionEvent e) {
* if (JXDatePicker.COMMIT_KEY.equals(e.getActionCommand)) {
* saveDate(picker.getDate());
* }
* }
* };
* picker.addActionListener(l);
*
*
* Note that ActionListener will not be notified if the user
* edits the date text without hitting the Enter key afterwards. To detect both kinds of
* date change, interested client code can add a PropertyChangeListener.
*
*
* JXDatePicker picker = new JXDatePicker(new Date());
* PropertyChangeListener listener = new PropertyChangeListener() {
* public void propertyChange(PropertyChangeEvent e) {
* if ("date".equals(e.getPropertyName()) {
* saveDate(picker.getDate());
* }
* }
* };
* picker.addPropertyChangeListener(listener);
*
*
*
* The DateFormats used in the JXDatePicker's are initialized to the default
* formats of the DatePickerFormatter, as defined by the picker's resourceBundle
* DatePicker.properties. Application code can overwrite the picker's default
*
*
* picker.setDateFormats(myCustomFormat, myAlternativeCustomFormat);
*
*
* PENDING JW: explain what the alternatives are for (after understanding it
* myself ;-)
*
*
* The selected Date is a bound property of the JXDatePicker. This allows easy
* binding to a property of a custom bean when using a binding framework.
*
*
* Keybindings (as installed by the UI-Delegate)
*
* - ENTER commits the edited or selected value
*
- ESCAPE reverts the edited or selected value
*
- alt-DOWN opens the monthView popup
*
- shift-F5 if monthView is visible, navigates the monthView to today
* (no effect otherwise)
*
- F5 commits today
*
*
* PENDNG JW: support per-OS keybindings to be installed, currently they are
* hardcoded in our (single) BasicDatePickerUI.
