/**
    @class wxCalendarCtrl

    The calendar control allows the user to pick a date.  The user can move the
    current selection using the keyboard and select the date (generating
    @c EVT_CALENDAR event) by pressing @c @<Return@> or double clicking it.

    Generic calendar has advanced possibilities for the customization of its
    display, described below. If you want to use these possibilities on every
    platform, use wxGenericCalendarCtrl instead of wxCalendarCtrl.

    All global settings (such as colours and fonts used) can, of course, be
    changed. But also, the display style for each day in the month can be set
    independently using wxCalendarDateAttr class.

    An item without custom attributes is drawn with the default colours and
    font and without border, but setting custom attributes with SetAttr()
    allows to modify its appearance. Just create a custom attribute object and
    set it for the day you want to be displayed specially (note that the
    control will take ownership of the pointer, i.e. it will delete it itself).
    A day may be marked as being a holiday, even if it is not recognized as
    one by wxDateTime using the wxCalendarDateAttr::SetHoliday() method.

    As the attributes are specified for each day, they may change when the
    month is changed, so you will often want to update them in
    @c EVT_CALENDAR_PAGE_CHANGED event handler.
