16 \brief A row of names for the days in a week.
17
18 DayOfWeekRow presents day of week names in a row. The names of the days
19 are ordered and formatted using the specified \l {Control::locale}{locale}.

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

109 \li \b model.shortName : string
110 \li The short version of the day name; for example, "Mon"
