Qt formatdatetime

The Qt object contains several functions for formatting QDateTime, QDateand QTimevalues. string Qt.formatDateTime(datetime date, variant format) string Qt.formatDate(datetime date, variant format) string Qt.formatTime(datetime date, variant format stringformatDateTime(datetimedateTime, variantformat) Returns a string representation of datetime, optionally formatted according to format. The dateparameter may be a JavaScript Dateobject, a dateproperty, a QDate, QTime, or QDateTimevalue. If formatis not provided, dateTimeis formatted using Qt.DefaultLocaleShortDate The QML documentation says to use Qt.formatDateTime (datetime date, format variant) to return a string, which seems to be a reformat of the C++ QString formatting functions. Well the problem is there is no straightforward way indicated in the docs to obtain the current datetime to format as available with QDate or QDateTime currentDate ()

To read a date value returned from a C++ extension class, use Qt.formatDate () and Qt.formatDateTime (). When integrating with C++, note that any QDate or QDateTime value passed into QML from C++ is automatically converted into a date value, and vice-versa No reviews matched the request. Check your Options in the drop-down menu of this sections header First, import the Qt Quick module. This gives us access to graphical primitives such as Item, Rectangle, Text, and so on. For a full list of types, see the Qt Quick QML Types documentation. We then add QtQuick.Layouts import, which we'll cover shortly. Next, import the Qt Quick Controls module
