1012 | so QDate (-4713, 1, 1) would be invalid). In that case we try to generate |
1013 | another valid date for that month. Later, returned date's day is the number of cells |
1014 | calendar widget will reserve for days before referenceDate. (E.g. if returned date's |
1015 | day is 16, that day will be placed in 3rd or 4th row, not in the 1st or 2nd row). |
1016 | Depending on referenceData we can change behaviour of Oct 1582. If referenceDate is 1st |
1017 | of Oct we render 1 Oct in 1st or 2nd row. If referenceDate is 17 of Oct we show always 16 |
1018 | dates before 17 of Oct, and since this month contains the hole 5-14 Oct, the first of Oct |
1019 | will be rendered in 2nd or 3rd row, showing more dates from previous month. |

2036 | \class QCalendarWidget |
2037 | \brief The QCalendarWidget class provides a monthly based |
2038 | calendar widget allowing the user to select a date. |
2039 | \since 4.2 |
2040 | |
2041 | \ingroup advanced |
2042 | \inmodule QtWidgets |
2043 | |
2044 | \image fusion-calendarwidget.png |
2045 | |
2046 | The widget is initialized with the current month and year, but |
2047 | QCalendarWidget provides several public slots to change the year |
2048 | and month that is shown. |
2049 | |
2050 | By default, today's date is selected, and the user can select a |
2051 | date using both mouse and keyboard. The currently selected date |
2052 | can be retrieved using the selectedDate() function. It is |
2053 | possible to constrain the user selection to a given date range by |
2054 | setting the minimumDate and maximumDate properties. |
2055 | Alternatively, both properties can be set in one go using the |
2056 | setDateRange() convenience slot. Set the \l selectionMode |
2057 | property to NoSelection to prohibit the user from selecting at |
2058 | all. Note that a date also can be selected programmatically using |
2059 | the setSelectedDate() slot. |
2060 | |
2061 | The currently displayed month and year can be retrieved using the |
2062 | monthShown() and yearShown() functions, respectively. |
2063 | |
2064 | A newly created calendar widget uses abbreviated day names, and |
2065 | both Saturdays and Sundays are marked in red. The calendar grid is |
2066 | not visible. The week numbers are displayed, and the first column |
2067 | day is the first day of the week for the calendar's locale. |
2068 | |
2069 | The notation of the days can be altered to a single letter |
2070 | abbreviations ("M" for "Monday") by setting the |
2071 | horizontalHeaderFormat property to |
2072 | QCalendarWidget::SingleLetterDayNames. Setting the same property |
2073 | to QCalendarWidget::LongDayNames makes the header display the |
2074 | complete day names. The week numbers can be removed by setting |
2075 | the verticalHeaderFormat property to |
2076 | QCalendarWidget::NoVerticalHeader. The calendar grid can be |
2077 | turned on by setting the gridVisible property to true using the |
2078 | setGridVisible() function: |
2079 | |
2080 | \table |
2081 | \row \li |
2082 | \image qcalendarwidget-grid.png |
2083 | \row \li |
2084 | \snippet code/src_gui_widgets_qcalendarwidget.cpp 0 |
2085 | \endtable |
2086 | |
2087 | Finally, the day in the first column can be altered using the |
2088 | setFirstDayOfWeek() function. |
2089 | |
2090 | The QCalendarWidget class also provides three signals, |
2091 | selectionChanged(), activated() and currentPageChanged() making it |
2092 | possible to respond to user interaction. |
2093 | |
2094 | The rendering of the headers, weekdays or single days can be |
2095 | largely customized by setting QTextCharFormat's for some special |
2096 | weekday, a special date or for the rendering of the headers. |
2097 | |
2098 | Only a subset of the properties in QTextCharFormat are used by the |
2099 | calendar widget. Currently, the foreground, background and font |
2100 | properties are used to determine the rendering of individual cells |
2101 | in the widget. |
