Hi Pengliang,

 

        It's not QthreadPool  I referred to. Its QThreadPoolThread which is derived from QThread. I am referring QT5.0.

 

//QThreadpool.cpp

/*

    QThread wrapper, provides synchronizitaion against a ThreadPool

*/

class QThreadPoolThread : public QThread

{

public:

    QThreadPoolThread(QThreadPoolPrivate *manager);

    void run();

    void registerTheadInactive();

 

    QThreadPoolPrivate *manager;

    QRunnable *runnable;

};

 

and 

 

//QThread.h

 

class Q_CORE_EXPORT QThread : public QObject

{

     ........

public:

    // default argument causes thread to block indefinetely

    bool wait(unsigned long time = ULONG_MAX);

 

    static void sleep(unsigned long);

    static void msleep(unsigned long);

    static void usleep(unsigned long);

 

........

};

 

Hope this helps.

 

 

Regards,

Amogh.

Hi

         Thank you.

But I check source code of Qt, QthreadPool is derived from Qobject, not Qthread.

 

 

Thanks

Ken

Hi Pengliang,

 

      I am not pretty sure but it may be possible as QThreadPoolThread is a friend class of Qrunnable class and 

QThreadPoolThread is derived from QThread and QThread has the sleep method.

Hope this helps.

 

Regards,

Amogh.
