The addSecs () and addMSecs () functions provide the time a given number of seconds or milliseconds later than a given time. Correspondingly, the number of seconds or milliseconds between two times can be found using secsTo () or msecsTo () Correspondingly, the number of seconds or milliseconds between two times can be found using secsTo () or msecsTo (). QTime can be used to measure a span of elapsed time using the start (), restart (), and elapsed () functions. See also QDate and QDateTime int QTime::msecsTo (const QTime & t) const Returns the number of milliseconds from this time to t (which is negative if t is earlier than this time). Because QTime measures time within a day and there are 86400 seconds in a day, the result is always between -86400000 and 86400000 msec. See also secsTo() As of Qt 4.7, QDateTime has a msecsTo method. See Qt 4.8 documentation at http://doc.qt.io/qt-4.8/qdatetime.html#msecsTo. QDateTime dateTime1 = QDateTime::currentDateTime(); // let's say exactly 5 seconds pass here... QDateTime dateTime2 = QDateTime::currentDateTime(); qint64 millisecondsDiff = dateTime1.msecsTo(dateTime2); // millisecondsDiff is equal to 500

The daysTo() function returns the number of days between two datetimes, secsTo() returns the number of seconds between two datetimes, and msecsTo() returns the number of milliseconds between two datetimes. QDateTime can store datetimes as local time or as UTC msecsTo (const QTime &) const : bool: operator!= (const QTime &other) const : bool: operator< (const QTime &other) const : bool: operator<= (const QTime &other) const : bool: operator== (const QTime &other) const : bool: operator> (const QTime &other) const : bool: operator>= (const QTime &other) const : int: restart int: second const : int: secsTo (const QTime &) const : boo Die Funktionen addSecs () und addMSecs () geben die Zeit an, die eine bestimmte Anzahl von Sekunden oder Millisekunden nach einer bestimmten Zeit liegt. Entsprechend kann die Anzahl der Sekunden oder Millisekunden zwischen zwei Zeitpunkten mit secsTo () oder msecsTo () ermittelt werden

Die Funktion daysTo gibt die Anzahl der Tage zwischen zwei Datumsangaben zurück, secsTo gibt die Anzahl der Sekunden zwischen zwei Datumsangaben zurück und msecsTo gibt die Anzahl der Millisekunden zwischen zwei Datumsangaben zurück msecsTo (const QElapsedTimer &other) const : qint64: nsecsElapsed const : bool: operator!= (const QElapsedTimer &other) const : bool: operator== (const QElapsedTimer &other) const : qint64: restart qint64: secsTo (const QElapsedTimer &other) const : void: start Static Public Functions Index.

qint64 QDateTime::msecsTo ( const QDateTime & other ) const is new in Qt-4.7 but the doc says nothing about it being new. for other functions like void QDateTime::setMSecsSinceEpoch ( qint64 msecs ) the docs tells you This function was introduced in Qt 4.7 I came up with a idea of cross checking my knowledge about Vectors and Lists. So, I started off with Qt's QList and QVector. I created a QList and QVector of 50000 object of another class and then iterated each with 'for' loop and 'foreach' loop separately

Hi everyone, I wrote both an image convolution directly using cuda kernel and then I tried using opencv cuda convolution on my Jetson nano (Jetpack 4.3) with cuda and opencv 4.0.0 recompiled after removing Jetpack opencv version.

The problem is. mapFichiers.insert(m_list->at(i).lastModified().msecsTo(QDateTime(QDate(1,1,1),QTime(1,1)))*-1,fileStringList.at(i));} @ to get the name of each file without the extension (here .mp3) sorted by date.

QTime - BlackBerry Nativ

I have recently decided to use Qt for making my 2D game. All was going well until i started thinking about the game loop. Previously (when i used SDL), it was something like this: int main(int argc, char* argv[]) { // Setup stuff // int lastTime, dt, timeLeft; while(!app Ich wollte nur mal sagen, dass ich die Implementierung davon richtig Kacke finde. Wieso? Wegen dem int als Parameter. Ich hab fast ne Stunde nach nem Fehler gesucht, wo der Intervall des QTimer 's negativ war, dabei war es nur so eine große Zahl, dass es einen Overflow provoziert hat. Meiner Meinung nach sollte es QTimer::start(qint64) lauten - genau der Datentyp, der QTimer::msecsTo.

Qt 5.11 QTime-Klasse - Gelös

Hi, I have a simple demo application that detect faces in video using OclCascadeClassifier from OpenCL module. The problem is that the detectMultiScale() is really slow I decided to run very simple test to have glance on performance of Qt models and overhead cost of using them. Something very simple as make 1M random strings with random size (note: rnd_str(int) return some random string with specified size) int n = 1000000; QStandardItemModel std(n, 1); for(int row =0; row <n; ++row) std.setData(std.index(row,0), rnd_str(rand() % 16)) Ich habe diesen Code: QDateTime setTime = QDateTime::fromString (QString(1970-07-18T14:15:09), Qt::ISODate); QDateTime current = QDateTime::currentDateTime(); uint msecs = setTime.time().msecsTo(current.time. In this example, we will learn how to format time as HH:MM:SS using datetime object. We will use %H for the two digit representation of hours from datetime object, %M for the two digit.
