  2. [static] QDate QDate:: fromString (const QString &string, Qt::DateFormat format = Qt::TextDate) Returns the QDate represented by the string, using the format given, or an invalid date if the string cannot be parsed. Note for Qt::TextDate: It is recommended that you use the English short month names (e.g. Jan). Although localized month names can also be used in Qt 5, they depend on the user's locale settings
  3. This function was introduced in Qt 5.2. QDateTime:: QDateTime (const QDate &date, const QTime &time, Qt::TimeSpec spec, int offsetSeconds) Constructs a datetime with the given date and time, using the time specification defined by spec and offsetSeconds seconds. If date is valid and time is not, the time will be set to midnight
  4. A QDate object is typically created by giving the year, month, and day numbers explicitly. Note that QDate interprets two digit years as is, i.e., years 0 - 99. A QDate can also be constructed with the static function currentDate (), which creates a QDate object containing the system clock's date. An explicit date can also be set using setDate ()

  7. QDate provides a full set of operators to compare two QDate objects where smaller means earlier, and larger means later. You can increment (or decrement) a date by a given number of days using addDays(). Similarly you can use addMonths() and addYears(). The daysTo() function returns the number of days between two dates

QString QDate :: toString ( Qt :: DateFormat- Format = Qt :: TextDate) const Dies ist eine überladene Funktion. Liefert das Datum als String. Der format- Parameter bestimmt das Format der Zeichenfolge. Wenn das Format Qt::TextDate, wird die Zeichenfolge in der Standardeinstellung formatier Qt :: TimeSpec QDateTime :: timeSpec const Gibt die Zeitangabe der Datums- und Uhrzeitangabe zurück. QDate :: shortMonthName und QTime::toString werden zum Generieren der Zeichenfolge verwendet, sodass die Namen von Tag und Monat unter Verwendung des Systemgebietsschemas, dh QLocale::system () , lokalisierte Namen sind. . Ein Beispiel für diese Formatierung ist Mi 20 Mai 03:40:13 1998. QDateprovides a full set of operators to compare two QDateobjects where smaller means earlier, and larger means later. You can increment (or decrement) a date by a given number of days using addDays(). Similarly you can use addMonths() and addYears(). The daysTo() function returns the number of days between two dates Qt documentation for the QDate class says that yyyy is recognized as a four digit year number. Second of all, fromString is a static function that returns a new QDate. Currently, the return value of that function is discarded : it is not written back into the Date variable, as you might think. The complete correct code should therefore look like this : QString date_string_on_db = 20/12/2015. According to the Qt documentation of QDate, you can specify the format you desire in QDate::toString(). Now, to avoid the repetitions that are bothering you, you can specify somewhere a static variable that contains the application formatting. Then you give it as parameter everytime you call QDate::toString(). This way, you will have to use always the same.

This function was introduced in Qt 5.2. QDateTime:: QDateTime (const QDate &date, const QTime &time, const QTimeZone &timeZone) Constructs a datetime with the given date and time, using the Time Zone specified by timeZone. If date is valid and time is not, the time will be set to 00:00:00. If timeZone is invalid then the datetime will be invalid This function was introduced in Qt 5.2. See also timeZone() and Qt::TimeSpec. void QDateTime:: swap (QDateTime &other) Swaps this datetime with other. This operation is very fast and never fails. This function was introduced in Qt 5.0. QTime QDateTime:: time const. Returns the time part of the datetime. See also setTime(), date(), and timeSpec() Qt5 has QDate, QTime, and QDateTime classes to work with date and time. The QDate is a class for working with a calendar date in the Gregorian calendar. It has methods for determining the date, comparing, or manipulating dates. The QTime class works with a clock time

All this and more can be handled by Qt's QDate class. QDate represents a date in the proleptic Gregorian calendar and has a variety of useful functions for handling all your date-related needs. An Example. To illustrate what you can do with QDate, I've written a simple program that demonstrates much of the class's functionality. This program implements a widget that lets the user specify a date by choosing a month and day from combo box menus, and a year by typing it into an.

I now, the question sounds rather silly, but I just can't get it to work. Worst example: QString time_format = yyyy-MM-dd HH:mm:ss; QDateTime a = QDateTime::currentDateTime (); QString as = a.toString (time_format); qDebug () << as; // print 2014-07-16 17:47:04 QDateTime b; b.fromString (as,time_format); assert (b.isValid ()); // fails The QDate class provides date functions. 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 because your dates are not initialized. Using static function on uninitialized object does not updates this object... @. QDate issueDate = QDate::currentDate (); QDate ReturnDate; QString IsDt= IssueDate.toString (Qt::ISODate); ReturnDate = IssueDate.addDays (15); QString RtDt= ReturnDate.toString (Qt::ISODate); @
