| 49 |     \brief A row of names for the days in a week. | 
| 50 |  | 
| 51 |     DayOfWeekRow presents day of week names in a row. The names of the days | 
| 52 |     are ordered and formatted using the specified \l {Control::locale}{locale}. |

| 55 |     \snippet qtlabscalendar-dayofweekrow.qml 1 | 
| 56 |  | 
| 57 |     DayOfWeekRow can be used as a standalone control, but it is most | 
| 58 |     often used in conjunction with MonthGrid. Regardless of the use case, | 
| 59 |     positioning of the row is left to the user. |

| 62 |     \snippet qtlabscalendar-dayofweekrow-layout.qml 1 | 
| 63 |  | 
| 64 |     The visual appearance of DayOfWeekRow can be changed by | 
| 65 |     implementing a \l {delegate}{custom delegate}. |
