Qt offers convenient classes for dealing with date/time values, but Qwt uses coordinate systems that are based on doubles. QwtDate offers methods to translate from QDateTime to double and v.v. A double is interpreted as the number of milliseconds since 1970-01-01T00:00:00 Universal Coordinated Time - also known as The Epoch. While the range of the Julian day in Qt4 is limited to [0, MAX_INT. A QDate object contains a calendar date, i.e. year, month, and day numbers, in the Gregorian calendar (Julian calendar for dates before 15 October 1582). It can read the current date from the system clock. It provides functions for comparing dates, and for manipulating dates. For example, it is possible to add and subtract days, months, and years to dates Recommended Data Types for Qt-Supported Database Systems. This table shows the recommended data types for extracting data from the databases supported in Qt. Note that types used in Qt are not necessarily valid as input types to a specific database system. e.g., A double might work perfectly as input for floating point records in a particular database, but not necessarily as a storage format. static constexpr QDate fromJulianDay (qint64 dayNumber) static QDate fromString (const QString &s, const QString &format) static QDate fromString (const QString &s, Qt::DateFormat f=Qt::TextDate) static bool isLeapYear (int year) static bool isValid (int y, int m, int d) static QString longDayName (int weekday, MonthNameType type=DateFormat. minimumDate: QDate. This property holds the minimum date of the date time edit. When setting this property the maximumDate is adjusted if necessary, to ensure that the range remains valid.
