    \brief A row of names for the days in a week.

    DayOfWeekRow presents day of week names in a row. The names of the days
    are ordered and formatted using the specified \l {Control::locale}{locale}.

           {Day of week row displaying weekday names}
    \snippet qtquickcontrols-dayofweekrow.qml 1

    DayOfWeekRow can be used as a standalone control, but it is most
    often used in conjunction with MonthGrid. Regardless of the use case,
    positioning of the row is left to the user.

    \snippet qtquickcontrols-dayofweekrow-layout.qml 1

    The visual appearance of DayOfWeekRow can be changed by
    implementing a \l {delegate}{custom delegate}.

    This property holds the item delegate that visualizes each day of the week.

    In addition to the \c index property, a list of model data roles
    are available in the context of each delegate:
    \table
        \row
        \li \b model.day : int
        \li The day of week (\l Qt::DayOfWeek)
        \row
        \li \b model.longName : string
        \li The long version of the day name; for example,
   "Monday" (\l QLocale::LongFormat)
        \row
        \li \b model.shortName : string
        \li The short version of the day name; for example, "Mon"
        (\l QLocale::ShortFormat)
        \row
        \li \b model.narrowName : string
        \li A special version of the day name for use when space is limited.
        For example, "M" (\l QLocale::NarrowFormat)
    \endtable

    The following snippet presents the default implementation of the item
    delegate. It can be used as a starting point for implementing custom
    delegates.
