    Warum kann ich in beiden Fällen den Text: "Vor ... " nicht lesen?

    void Widget::MyMethodeSleepTest()
    {
    label->setText("vor SLEEP()"); Sleep(1000); label->setText("nach SLEEP");
    }
    void Widget::MyMethodeTimeTest()
    {
    QTime time; label->setText("vor Time()");
    time.start(); while (time.elapsed() < 1000);
    label->setText("nach Time");
    }
    Es scheint, als ob die Schleifen Sleep (windows.h) oder while betreten werden, bevor die setText-Methode
    abgearbeitet ist.
    Weiss einer Rat?#

      Sie verwenden einen "Thread"?

      Versuchen Sie es mit "QThread::msleep"

      @QThread::sleep(secs);//seconds
      QThread::msleep(msecs);//milleseconds
      QThread::usleep(usecs);//microseconds@
