Thanks!
There is nothing difference. Here is code of original QThread::exec method :
Qt Code: 
  1. int QThread::exec()
  2. {
  3.     Q_D(QThread);
  4.     QMutexLocker locker(&d->mutex);
  5.     d->data->quitNow = false;
  6.     QEventLoop eventLoop;
  7.     locker.unlock();
  8.     int returnCode = eventLoop.exec();
  9.     return returnCode;
  10. }

As You see You never create and exec event loop. Yours Thread class must be defined something like that :
Qt Code: 
  1. class Thread : public QThread
  2. {
  3. Q_OBJECT
  4.  
  5. public:
  6.     Thread();
  7. signals:
  8.     void testSignal(QString message);
  9. slots:
  10.     void mTimeOut();
  11. protected:
  12.     void run();
  13. };
  14.  
  15. Thread::Thread()
  16. {
  17. }
  18.  
  19. void Thread::run()
  20. {
  21.     QTimer::singleShot(0, this, SLOT(mTimeOut()));
  22.  
  23.     exec();
  24. }
  25.  
  26. void Thread::mTimeOut()
  27. {
  28.     //do what You need in one step
  29.     emit(testSignal("hello world!"));
  30.     //do sleep and after start next step
  31.     QTimer::singleShot(1, this, SLOT(mTimeOut()));
  32. }
