  13
  14 The calendar control allows the user to pick a date. For this,
  15 it displays a window containing several parts: a control at the top to pick the month
  16 and the year (either or both of them may be disabled), and a month
  17 area below them which shows all the days in the month. The user can move the
  18 current selection using the keyboard and select the date (generating
  19 {\tt EVT\_CALENDAR} event) by pressing {\tt <Return>} or double clicking it.
  20
  21 It has advanced possibilities for the customization of its display. All global
  22 settings (such as colours and fonts used) can, of course, be changed. But
  23 also, the display style for each day in the month can be set independently
  24 using \helpref{wxCalendarDateAttr}{wxcalendardateattr} class.
  25
  26 An item without custom attributes is drawn with the default colours and
  27 font and without border, but setting custom attributes with
  28 \helpref{SetAttr}{wxcalendarctrlsetattr} allows to modify its appearance. Just
  29 create a custom attribute object and set it for the day you want to be
  30 displayed specially (note that the control will take ownership of the pointer,
  31 i.e. it will delete it itself). A day may be marked as being a holiday, even
  32 if it is not recognized as one by \helpref{wxDateTime}{tdateholidays} using
  33 \helpref{SetHoliday}{wxcalendardateattrsetholiday} method.
  34
  35 As the attributes are specified for each day, they may change when the month
  36 is changed, so you will often want to update them in
  37 {\tt EVT\_CALENDAR\_MONTH} event handler.
