 173
 174     The calendar control allows the user to pick a date.  The user can move the
 175     current selection using the keyboard and select the date (generating
 176     @c EVT_CALENDAR event) by pressing @c Return or double clicking it.
 177
 178     Generic calendar has advanced possibilities for the customization of its
 179     display, described below. If you want to use these possibilities on
 180     every platform, use wxGenericCalendarCtrl instead of wxCalendarCtrl.
 181
 182     All global settings (such as colours and fonts used) can, of course,
 183     be changed. But also, the display style for each day in the month can
 184     be set independently using wxCalendarDateAttr class.
 185
 186     An item without custom attributes is drawn with the default colours and
 187     font and without border, but setting custom attributes with
 188     wxCalendarCtrl::SetAttr allows to modify its appearance. Just
 189     create a custom attribute object and set it for the day you want to be
 190     displayed specially (note that the control will take ownership of
 191     the pointer, i.e. it will delete it itself).
 192     A day may be marked as being a holiday, even if it is not recognized as
 193     one by wxDateTime using wxCalendarDateAttr::SetHoliday method.
 194
 195     As the attributes are specified for each day, they may change when the month
 196     is changed, so you will often want to update them in
 197     @c EVT_CALENDAR_PAGE_CHANGED event handler.
