+
+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.
