Description
============

class CalendarField

This class is a DateField with which one can select a date via a DropDownButton
and the CalendarControl.

--------------------------------------------------------------------------

WinBits

See DateField

The preferences for the CalendarControl can be set via SetCalendarStyle().

--------------------------------------------------------------------------

With EnableToday()/EnableNone() we can enable a TodayButton and a NoneButton.

--------------------------------------------------------------------------

Because we only take over the start date into the field, we should query
with GetCalendar() in the SelectHandler and with GetSelectDateCount()/GetSelectDate()
the selected range. We then can e.g. take over that value to another field.

--------------------------------------------------------------------------

If a derived Calendar should be used, we can override the CreateCalendar()
method in CalendarField and create an own calendar there ourselves.
