actualDate()

static QDate actualDate ( QDateTimeParser::Sections  known, const QCalendar &  calendar, int  year, int  year2digits, int  month, int  day, int  dayofweek  )

static

Returns a date consistent with the given data on parts specified by known, while staying as close to the given data as it can. Returns an invalid date when on valid date is consistent with the data.
