[Solved] createRequest does not finish

[brcontainer]

I can not do QNetworkAccessManager::createRequest finalize request. I tried finished(QNetworkRequest), but nothing happens, see how was the WebInspector:

The request is pending and never ends.

What am I doing wrong?

My code:

@QNetworkReply * myNAM::createRequest(Operation op, const QNetworkRequest &request, QIODevice *outgoingData){
QNetworkAccessManager *n = new QNetworkAccessManager();

 QNetworkRequest req(request.url());

 const QList<QByteArray>a = request.rawHeaderList();
 int j = a.length();
 int i=0;

 for(;i<j;++i){
  req.setRawHeader(a[i],request.rawHeader(a[i]));
 }

 QList<QNetworkCookie> cookies = CookiesGlobals->cookiesForUrl(request.url());
 n->cookieJar()->setCookiesFromUrl(cookies,request.url());

 QNetworkReply *p;
 if(op==PostOperation) {
  const QByteArray data = outgoingData->readAll();
  p = n->post(req, data);
 } eles {
  p = n->get(req);
 }

 QEventLoop loop;
 connect(p, SIGNAL(finished()), &loop, SLOT(quit()));
 loop.exec&#40;&#41;;

 QVariant statusCode = p->attribute(QNetworkRequest::HttpStatusCodeAttribute&#41;;
 if (statusCode.isValid()){
  int status = statusCode.toInt();
  qDebug() << "FB: " status;
 } else {
  qDebug() << "FB: statusCode isInvalid";
 }
 finished(p);
 return p;
}@

Solution, removed QEventLoop, update code:
