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.
