Hi,

first of all, sorry for my bad English.
Now the question.

I've written a class inherited from QThread
Qt Code: 
  1. // DataSender.cpp
  2.  
  3. DataSender::DataSender(QObject *parent) : QThread(parent)
  4. {
  5.     this->m_sendTimer.setInterval (0);
  6.  
  7.     connect (&m_sendTimer, SIGNAL(timeout()), this, SLOT(sendData()));
  8. }
  9.  
  10. void DataSender::setSendInterval (int msec)
  11. {
  12.     this->m_sendTimer.setInterval (msec);
  13. }
  14.  
  15. void DataSender::run ()
  16. {
  17.     bool ans = true;
  18.  
  19.     qDebug ("%s Started", qPrintable(this->objectName ()));
  20.  
  21.     if (ans && this->m_sendTimer.interval () > 0) {
  22.         this->m_sendTimer.start ();
  23.         qDebug ("%s: Timer Started", qPrintable(this->objectName ()));
  24.     }
  25.  
  26.     if (ans) {
  27.         this->exec ();
  28.     }
  29.  
  30.     this->m_sendTimer.stop ();
  31.  
  32.     qDebug ("%s Stopped", qPrintable(this->objectName ()));
  33. }

This class is in a library.

When I use it in a GUI Application it works
Qt Code: 
  1. void MainWindow::startSenders ()
  2. {
  3.     DataSender* s = 0;
  4.     for (int i = 0; i < DATA_TYPE_SIZE; ++i) {
  5.         s = &this->m_senders[i];
  6.         s->setSendInterval (10000);
  7.         s->sender->start ();
  8.     }
  9.     qDebug ("Senders Started");
  10. }
To copy to clipboard, switch view to plain text mode 

but when I use it in a non-GUI application
Qt Code: 
  1. // Main.cpp
  2. ...
  3.     DataSender* senders[2];
  4.  
  5.     senders[0] = new DataSender;
  6.     senders[0]->setSendInterval(1000);
  7.  
  8.     senders[1] = new DataSender;
  9.     senders[1]->setSendInterval(5000);
  10.  
  11.     qDebug ("RUNNING...");
  12.  
  13.     for (int i = 0; i < 2; ++i) {
  14.         senders[i]->start ();
  15.     }
  16.     result = app.exec ();
  17. ...

the slot connected to the timeout() signal of timer is never called.
The debug messages in DataSender.cpp at line 19 and 23 are printed; that means the thread is correctly started.

Any suggestion?
