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

Question

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

Answer 1

To use the standard sleep function add the following in your .cpp file:

#include 

As of Qt version 4.8, the following sleep functions are available:

void QThread::msleep(unsigned long msecs)
void QThread::sleep(unsigned long secs)
void QThread::usleep(unsigned long usecs)

To use them, simply add the following in your .cpp file:

#include 

Reference: QThread (via Qt documentation): http://doc.qt.io/qt-4.8/qthread.html

Otherwise, perform these steps...

Modify the project file as follows:

CONFIG += qtestlib

Note that in newer versions of Qt you will get the following error:

Project WARNING: CONFIG+=qtestlib is deprecated. Use QT+=testlib instead.

... so, instead modify the project file as follows:

QT += testlib

Then, in your .cpp file, be sure to add the following:

#include 

And then use one of the sleep functions like so:

usleep(100);
