I was intrigued by the post http://labs.qt.nokia.com/2010/06/17/...oing-it-wrong/ and really like that idea of new way of using threads. So I wrote a simple example, which... does not work
Qt Code: 
  1. #ifndef THREADs_TEST_H
  2. #define THREADs_TEST_H
  3.  
  4. #if defined(_WIN32)
  5. 	#include <windows.h>
  6. #elif defined(__GNUC__)
  7. 	#include <unistd.h>
  8. 	#define Sleep(x) sleep((x)/1000)
  9. #endif //_WIN32
  10.  
  11. #include <iostream>
  12. #include <QThread>
  13. #include <QObject>
  14. #include <QDialog>
  15. #include <QDialogButtonBox>
  16. #include <QBoxLayout>
  17. #include <QPushButton>
  18.  
  19. class Cycler : public QObject
  20. {
  21. 	Q_OBJECT
  22. 	public:
  23. 		Cycler() : QObject() {};
  24. 		virtual ~Cycler(){stop();};
  25. 	signals:
  26. 		void done();
  27. 	public slots:
  28. 		void cycle() {
  29. 			arbeit = true;
  30. 			int i = 0;
  31. 			while(arbeit)  {
  32. 				Sleep(1000);
  33. 				std::cout << i++ << " " << std::flush; 				
  34. 			};
  35. 			emit done(); };
  36. 		void stop(){ arbeit = false;};
  37. 	private:
  38. 		volatile bool arbeit;
  39. };
  40.  
  41. class CyclerDialog: public QDialog
  42. {
  43. 	Q_OBJECT
  44. 	public:
  45. 		explicit CyclerDialog(QWidget* parent = 0, Qt::WindowFlags f = 0) : QDialog(parent, f){
  47. 			QVBoxLayout *main_layout = new QVBoxLayout;
  48. 			main_layout->addWidget(buttons);
  49. 			setLayout(main_layout);
  50.  
  51. 			cycl.moveToThread(&thrd);
  52. 			connect(buttons, SIGNAL(accepted()), &thrd, SLOT(start()));
  53. 			connect(&thrd, SIGNAL(started()), &cycl, SLOT(cycle()));
  54. 			connect(buttons, SIGNAL(rejected()), &cycl, SLOT(stop()));
  55. 			connect(&cycl, SIGNAL(done()), &thrd, SLOT(quit())); };
  56.  
  57. 		virtual ~CyclerDialog(){thrd.wait(1000);};
  58. 	private:
  59. 		Cycler  cycl;
  60. 		QThread thrd;
  61. };
  62.  
  63. #endif // THREADs_TEST_H
To copy to clipboard, switch view to plain text mode 

Qt Code: 
  1. #include <QApplication>
  2. #include "threads_test.h"
  3.  
  4. int main(int argc, char *argv[])
  5. {
  6. 	QApplication app(argc, argv);
  7. 	CyclerDialog window;	
  8. 	window.show();
  9. 	return(app.exec());
  10. }

It is supposed to start printing numbers in std::cout when OK is clicked, and stop when CANCEL is clicked, but apparently stop() slot is never called. WHY????
