org.freixas.jcalendar.JCalendarCombo
This class is a combo box that allows you to select a date either by typing one in (if the combo box is editable) or through a JCalendar pop-up. Normally, a combo box expects to use a a popup that contains a list. We've perverted this a bit; while you can select a variety of dates, the list always has one item which changes to match the selected date.
You may specify a font for each of the elements that make up the pop-up calendar. If you do not specify a font (or specify a null font), a reasonable default will be generated based on the current Look & Feel.
The JCalendarCombo uses a non-mutable ComboBoModel. This means that the following methods will generate an exception:
- addItem()
- insertItemAt()
- removeItem()
- removeItemAt()
- removeAllItems()
You would be ill-advised to to call setModel() with your own ComboBoxModel unless you use some variant of a JCalendarCombo.CalendarComboBoxModel class.
The combo box listeners work pretty much as for normal combo boxes. The item changed event reports the date "unselected" (the previous date) and "selected" (the new date set), but as Strings. It's probably better to add a DateListener and ignore the ItemListener and ActionListener.
The following key bindings should work (some may depend on the selected Look-and-Feel):
- Left Arrow - Move back a month.
- Right Arrow - Move forward a month.
- Shift Left Arrow - Move back a year.
- Shift Right Arrow - Move forward a year.
- Down Arrow - Display the calendar pop-up (if not visible).
- Up Arrow - Apply any change and hide the calendar pop-up (if visible);
- Escape - Cancel any changes and hide the calendar pop-up (if visible).
- Delete - Unselect all dates only if isNullAllowed() is true).
- BackSpace - Same as Delete.
- Return - Accept the selected date and hide the calendar pop-up (if visible).
This component tries to adapt it's Look-and-Feel to match the current Look-and-Feel. But it can only do so for Look-and-Feels's that it knows about. To adapt it for new Look-and-Feels, create a sub-class:
```
 public class MyCalendarCombo extends JCalendarCombo { public void updateUI() { ComboBoxUI cui = (ComboBoxUI)UIManager.getUI(this); if (cui instanceof SomeLAFComboBoxUI) { cui = new SomeLAFCalComboBoxUI(); } else { super.updateUI(); } } private class SomeLAFCalComboBoxUI extends SomeLAFComboBoxUI { return new CalendarComboPopup(); } } 
```
If it can't figure out an appropriate Look-and-Feel, it uses the Metal Look-and-Feel. @author Antonio Freixas
