/* |

974 |
This simple algorithm tries to generate a valid date from the month shown. |
|
975 |
Some months don't contain a first day (e.g. Jan of -4713 year, |
|
976 |
so QDate (-4713, 1, 1) would be invalid). In that case we try to generate |
|
977 |
another valid date for that month. Later, returned date's day is the number of cells |
|
978 |
calendar widget will reserve for days before referenceDate. (E.g. if returned date's |
|
979 |
day is 16, that day will be placed in 3rd or 4th row, not in the 1st or 2nd row). |
|
980 |
Depending on referenceData we can change behaviour of Oct 1582. If referenceDate is 1st |
|
981 |
of Oct we render 1 Oct in 1st or 2nd row. If referenceDate is 17 of Oct we show always 16 |
|
982 |
dates before 17 of Oct, and since this month contains the hole 5-14 Oct, the first of Oct |
|
983 |
will be rendered in 2nd or 3rd row, showing more dates from previous month. |

The widget is initialized with the current month and year, but |

1969 |
QCalendarWidget provides several public slots to change the year |

By default, today's date is selected, and the user can select a |
|
1973 |
date using both mouse and keyboard. The currently selected date |
|
1974 |
can be retrieved using the selectedDate() function. It is |
|
1975 |
possible to constrain the user selection to a given date range by |
|
1976 |
setting the minimumDate and maximumDate properties. |
|
1977 |
Alternatively, both properties can be set in one go using the |
|
1978 |
setDateRange() convenience slot. Set the \l selectionMode |
|
1979 |
property to NoSelection to prohibit the user from selecting at |
|
1980 |
all. Note that a date also can be selected programmatically using |
|
1981 |
the setSelectedDate() slot. |
|
1982 |
||
1983 |
The currently displayed month and year can be retrieved using the |
|
1984 |
monthShown() and yearShown() functions, respectively. |
|
1985 |
||
1986 |
A newly created calendar widget uses abbreviated day names, and |
|
1987 |
both Saturdays and Sundays are marked in red. The calendar grid is |
|
1988 |
not visible. The week numbers are displayed, and the first column |
|
1989 |
day is Sunday. |
|
1990 |
||
1991 |
The notation of the days can be altered to a single letter |
|
1992 |
abbreviations ("M" for "Monday") by setting the
|
|
1993 |
horizontalHeaderFormat property to |
|
1994 |
QCalendarWidget::SingleLetterDayNames. Setting the same property |
|
1995 |
to QCalendarWidget::LongDayNames makes the header display the |
|
1996 |
complete day names. The week numbers can be removed by setting |
|
1997 |
the verticalHeaderFormat property to |
|
1998 |
QCalendarWidget::NoVerticalHeader. The calendar grid can be |
|
1999 |
turned on by setting the gridVisible property to true using the |
|
2000 |
setGridVisible() function: |
|
2001 |
||
2002 |
\table |
|
2003 |
\row \o |
|
2004 |
\image qcalendarwidget-grid.png |
|
2005 |
\row \o |
|
2006 |
\snippet doc/src/snippets/code/src_gui_widgets_qcalendarwidget.cpp 0 |
|
2007 |
\endtable |
|
2008 |
||
2009 |
Finally, the day in the first column can be altered using the |
|
2010 |
setFirstDayOfWeek() function. |
|
2011 |
||
2012 |
The QCalendarWidget class also provides three signals, |
|
2013 |
selectionChanged(), activated() and currentPageChanged() making it |
|
2014 |
possible to respond to user interaction. |
|
2015 |
||
2016 |
The rendering of the headers, weekdays or single days can be |
|
2017 |
largely customized by setting QTextCharFormat's for some special |
|
2018 |
weekday, a special date or for the rendering of the headers. |
|
2019 |
||
2020 |
Only a subset of the properties in QTextCharFormat are used by the |
|
2021 |
calendar widget. Currently, the foreground, background and font |
|
2022 |
properties are used to determine the rendering of individual cells |
|
2023 |
in the widget. |
