Description
============
class Calendar
This class allows for the selection of a date. The displayed date range is
the one specified by the Date class. We display as many months as we have
space in the control. The user can switch between months using a ContextMenu
(clicking on the month's name) or via two ScrollButtons in-between the months.
--------------------------------------------------------------------------
WinBits
WB_BORDER We draw a border around the window.
WB_TABSTOP Keyboard control is possible. We get the focus, when
the user clicks in the Control.
WB_QUICKHELPSHOWSDATEINFO Show DateInfo as BallonHelp even if QuickInfo is enabled
WB_BOLDTEXT We format by bold texts and DIB_BOLD is evaluated by
AddDateInfo()
WB_FRAMEINFO We format in a way, so that FrameInfo can be displayed
and the FrameColor is evaluated by AddDateInfo()
WB_RANGESELECT The user can select multiple days, which need to be
consecutive
WB_MULTISELECT The user can select multiple days
WB_WEEKNUMBER We also display the weekdays
--------------------------------------------------------------------------
We set and get the selected date by SetCurDate()/GetCurDate().
If the user selects a date Select() is called. If the user double clicks
DoubleClick() is called.
--------------------------------------------------------------------------
CalcWindowSizePixel() calculates the window size in pixel that is needed
to display a certain number of months.
--------------------------------------------------------------------------
SetSaturdayColor() and SetSundayColor() set a special color for Saturdays
and Sundays.
AddDateInfo() marks special days. With that we can set e.g. public holidays
to another color or encircle them (for e.g. appointments).
If we do not supply a year in the date, the day is used in EVERY year.
AddDateInfo() can also add text for every date, which is displayed if the
BalloonHelp is enabled.
In order to not have to supply all years with the relevant data, we call
the RequestDateInfo() handler if a new year is displayed. We can then query
the year in the handler with GetRequestYear().
--------------------------------------------------------------------------
In order to display a ContextMenu for a date, we need to override the
Command handler. GetDate() can infer the date from the mouse's position.
If we use the keyboard, the current date should be use.
If a ContextMenu is displayed, the baseclass' handler must not be called.
--------------------------------------------------------------------------
For multiple selection (WB_RANGESELECT or WB_MULTISELECT) SelectDate(),
SelectDateRange() can select date ranges. SelectDateRange() selects
including the end date.
SetNoSelection() deselects everything.
SetCurDate() does not select the current date, but only defines the focus
rectangle.
GetSelectDateCount()/GetSelectDate() query the selected range.
IsDateSelected() queries for the status of a date.
The SelectionChanging() handler is being called while a user selects a
date. In it, we can change the selected range. E.g. if we want to limit
or extend the selected range. The selected range is realised via SelectDate()
and SelectDateRange() and queried with GetSelectDateCount()/GetSelectDate().
IsSelectLeft() returns the direction of the selection:
sal_True is a selection to the left or up
sal_False is a selection to the right or down
--------------------------------------------------------------------------
If the DateRange area changes and we want to take over the selection, we
should only do this is if IsScrollDateRangeChanged() retruns sal_True.
This method returns sal_True if the area change was triggered by using the
ScrollButtons and sal_False if it was triggered by Resize(), other method
calls or by ending a selection.

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.
--------------------------------------------------------------------------
If we set WB_RANGESELECT with SetCalendarStyle(), we can select multiple days
in the Calendar.
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.
