Qt5 / C++ - Time delay, Windows 10 - Windows 7

[anda_skoa]

QTime::currentTime can be a very costly call.

But maybe you can explain what you are actually trying to do?
That doesn't look like anything that would appear in a real program.

Hello anda_skoa,

Thanks for your reply.
I'm doing nothing more than moving a QLabel around a form, with the delay between moves.

Hmm.

Wouldn't that be easier with a QPropertyAnimation?

If You really need this method do it like this :

void myProg:tDelay(int milliSecs)
{
    QElapsedTimer timer;
    timer.restart();
    qint64 nanoSec;
    timer.start();
    QEventLoop loop;
    QTimer::singleShot( milliSecs,&loop,SLOT(quit()) );
    loop.exec();
 
    nanoSec = timer.nsecsElapsed();
    qDebug() << nanoSec;
}

void myProg:tDelay(int milliSecs)
{
    QElapsedTimer timer;
    timer.restart();
    qint64 nanoSec;
    timer.start();
    QEventLoop loop;
    QTimer::singleShot( milliSecs,&loop,SLOT(quit()) );
    loop.exec();

    nanoSec = timer.nsecsElapsed();
    qDebug() << nanoSec;
}

Helo,

Thanks to anda_skoa and Lesiok.

Yes, some nice effects.

If You really need this method do it like this :

Gives a simiar result between the two systems.
