How do I create a pause/wait function using Qt?

I'm playing around with Qt, and I want to create a simple pause between two commands. However it won't seem to let me use Sleep(int mili);, and I can't find any obvious wait functions.

I am basically just making a console application to test some class code which will later be included in a proper Qt GUI, so for now I'm not bothered about breaking the whole event-driven model.

sleep wait qt c++

we can use following method QT_Delay:

QTimer::singleShot(2000,this,SLOT(print_lcd()));

This will wait for 2 seconds before calling print_lcd().

This work fine with Qt5:

void wait( int ms ) {
   QElapsedTimer timer;
   timer.start();

   while ( timer.elapsed() < ms )
       QCoreApplication::processEvents();
}
