Thread design advice needed

[jonks]

My question is inside the run function below

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 
 
    }
};

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 
		
    }
};
