Direct Known Subclasses:

MetalCalendarPanelUI, MotifCalendarPanelUI, WindowsCalendarPanelUI

public class BasicCalendarPanelUI
extends ComponentUI

The BASIC look and feel UIDelegate for the CalendarPanel. It is envisaged that this is subclasses to provide something more acceptable. A Windows and Metal one are provided. A Look and Feel delegate for the CalenderPanel. This version renders the selected date with a raised border and dashed focus indicator. TAB moves around the calendar, Shift-Tab jumps out to the next component. The arrow keys move around the panel stopping (i.e. not rolling over) at the ends.
