Qt:how to give a delay in loop execution

Question

hello,

In my application I want that when a loop is being executed,each time the control transfers to the loop,each execution must be delayed with a particular time.Can anyone tell me how can i do this?

Thank you.

EDIT (removed wrong solution). EDIT (to add this other option):

Another way to use it would be subclass QThread since it has protected *sleep methods.

QThread::usleep(unsigned long microseconds);
QThread::msleep(unsigned long milliseconds);
QThread::sleep(unsigned long second);

Here's the code to create your own *sleep method.

#include <QThread>    

class Sleeper : public QThread
{
public:
    static void usleep(unsigned long usecs){QThread::usleep(usecs);}
    static void msleep(unsigned long msecs){QThread::msleep(msecs);}
    static void sleep(unsigned long secs){QThread::sleep(secs);}
}

and you call it by doing this:

Sleeper::usleep(10);
Sleeper::msleep(10);
Sleeper::sleep(1);

This would give you a delay of 10 microseconds, 10 milliseconds or 10 seconds, accordingly.

Hope this helps.
