//METODO 1:
//Using the class QTest
QTest::qSleep(100); // it block the event processing
QTest::qWait(100);  // it does not block the event processing
 
//METODO 2:
//Using the classes QWaitCondition and QMutex
QWaitCondition waitCondition;
QMutex mutex;
 
waitCondition.wait(&mutex, 100);
 
//METODO 3:
//Or derive our class from QThread
class Thread : public QThread

public:
    static void msleep(int ms)
    {
        QThread::msleep(ms);
    }
};
