Thread design advice needed

My question is inside the run function below ;)

Code:

---

class TestObject : public QThread
{
    Q_OBJECT
private:
    QNetworkReply *m_reply;
    QUrl m_url;
 
public slots:
    void gotNetworkHeader()
    {
		// do something
    }
 
public:
    TestObject(QUrl url) : m_url(url)
    {
    }
 
    void run()
    {
        QNetworkAccessManager nam;
        m_reply = nam.head(QNetworkRequest(m_url));
        connect(m_reply, SIGNAL(finished()), this, SLOT(gotNetworkHeader()));
 
		//
		// what do I do here to stop the thread from 
		// exiting until gotNetworkHeader has finished
		// execution?
		//
 
                // I've tried exec(), but this seems to block QNetworkAccessManager 
 
    }
};

I just stumbled across this, which has some examples which are completely different to my design, but do exactly what I want.

simple
assign a private bool function
private:
bool stop;

in your constructor
stopped = false; //declare it
also use connect here itself in constructor

in run () function

Code:

---

while(stop)
{
     //busy line  ...
}

---

and in private slot

Code:

---

gotNetworkHeader()
{
    stop = true;
}

Actually exec() would do the job. Just remember the QThread object lives in the main thread and not in the thread it controls.
