Qt Object::connect: No such slot Signal to Thread Slot

Question

i try to invoke Slot in thread object when threas started but getting this error:

Object::connect: No such slot Worker::doWork(pFoo)

the thread executing code:

// main class   

            m_WorkerThread = new QThread();

             FooStack* pfooStack = InternalStorageManager::getInstance()->getStack();
             m_Worker = new Worker();
             bool done = connect(m_WorkerThread,
                                    SIGNAL(started()),
                                    m_Worker,
                                    SLOT(doWork(pfooStack))); 

             m_Worker->moveToThread(m_WorkerThread);          
             m_WorkerThread->start();



// class Worker
 // cpp imple            
void Worker::doWork(FooStack *& rp_urlsStack)
{

}
// header 
class Worker : public QObject
{

    Q_OBJECT

    public :

        Worker();
        ~Worker();
    public slots:
        void doWork(FooStack *&);

};

Object::connect: No such slot Worker::doWork(pFoo)

You can't pass objects in connection declarations.

Can't you pass pfooStack into the Worker constructor?

EDIT:

class Main : ...
{
    ...
    void startThread();  // The method in your example.
private slots:
     void startWork();
    ...
};

void Main::startThread()
{
     m_WorkerThread = new QThread();
     m_Worker = new Worker();
     bool done = connect(m_WorkerThread, SIGNAL(started()),
                         this, SLOT(startWork())); 

     m_Worker->moveToThread(m_WorkerThread);          
     m_WorkerThread->start();
}

void Main::startWork()
{
     m_Worker->doWork(InternalStorageManager::getInstance()->getStack());
}
