Hi ,
before sending this issue to Trolltech maybe some one of you, skilled people, can answer where I'm wrong:

Qt Code: 
  1. //main.cpp
  2.  
  3. include <QtCore>
  4.  int main(int argc, char **argv)
  5.  {
  6. 	QFile f("main.cpp");
  7. 	f.open(QIODevice::ReadOnly);
  8. 	QTextStream ts(&f);
  9. 	QString s = ts.readLine();
  10. 	qDebug("%s", s.toLatin1().data());
  11. 	f.flush();
  12. 	f.close();     
  13. 	f.setFileName("pippo.txt");
  14. 	f.open(QIODevice::ReadOnly);
  15. 	ts.flush(); //does nothing
  16. 	ts.setDevice(&f); //AGAIN?
  17. 	s = ts.readLine();
  18. 	qDebug("This one will not work");
  19. 	qDebug("First line: %s", s.toLatin1().data());
  20. 	ts.seek(0);
  21. 	s = ts.readLine();
  22. 	qDebug("This one will work");
  23. 	qDebug("First line: %s", s.toLatin1().data());
  24.  
  25. 	return 0;
  26.  } 
  27.  
  28. //pippo.txt
  29. ** If you read this line the QTextStream class works **
