QNetworkAccessManager::head not working

I have some code like this:

Code:

---

QNetworkAccessManager nam;
QNetworkRequest request(url);
m_reply = nam.head(request);
 
connect(m_reply, SIGNAL(readyRead()), this, SLOT(gotNetworkHeader()));
connect(m_reply, SIGNAL(finished(QNetworkReply*)), this, SLOT(headFinished(QNetworkReply*)));

---

readyRead and finished are never signaled.
Does anyone know why?:confused:

Sure. Your object goes out of scope and is destroyed.

m_reply is already class scope, but the QNetworkAccessManager object was not.
I just moved it to class scope, but It still does not work.

In the constuctor:

Code:

---

{
    ...
    m_nam = new QNetworkAccessManager(this);
    ...
}

---

In a class method:

Code:

---

{
    m_reply = m_nam->head(QNetworkRequest(url));
    connect(m_reply, SIGNAL(readyRead()), this, SLOT(gotNetworkHeader()));
}

---

There are are no runtime errors reported by when the connect function is called.

...But still no signal is emitted???

Do you remember to run the event loop? Does the same request using get instead of head finishes correctly?

I got it

readReady() is the wrong signal.
I should have been connecting the finished() signal.

I now works.
Of course wysota - putting QNetworkAccessManager at class scope is required too.
Thanks
