title: QNetworkRequest (HTTP GET) doesn't fire, after refactoring into a standalone class
body: <p>I've recently began the tedious process of modularising a large, monolithic audio player application that I wrote roughly 2 months ago. </p>
  
  <p>This process is going reasonably well, although it appears that one of the methods (ScrobbleMedia - which predictably enough makes HTTP requests to submit information about a playing track to last.fm) no longer seems to make network requests. </p>
  
  <p>However, the QUrl object that would be passed through to the QNetworkAccessManager instance/QNetworkRequest is being built correctly.</p>
  
  <p>For comparison, a functional Mercurial revision of the code is available on <a href="https://bitbucket.org/vmlemon/audioplayer/src/b655a64e824a/audioplayer.cpp" rel="nofollow">BitBucket</a>.</p>
  
  <p>The ScrobbleMedia method currently looks like this, after refactoring:</p>
  
  <pre><code>#include "scrobblemedia.h"
  
  #include &lt;QDebug&gt;
  #include &lt;cstdio&gt;
  
  ScrobbleMedia::ScrobbleMedia(QString asUsername, QString asPassword,
                           QString asArtist, QString asTrack, QString asAlbum)
  {
  
      QString KEndPointURL = "http://lastfmstats.livefrombmore.com/universalscrobbler/scrobble.php";
      QUrl iScrobbleEndPoint(KEndPointURL);
  
        QNetworkAccessManager *iScrobbleDispatcher = new QNetworkAccessManager(this);
  
  
  iScrobbleEndPoint.addQueryItem("submissionType","track");
  iScrobbleEndPoint.addQueryItem("username", asUsername);
  iScrobbleEndPoint.addQueryItem("password", asPassword);
  iScrobbleEndPoint.addQueryItem("artist", asArtist);
  iScrobbleEndPoint.addQueryItem("track", asTrack);
  iScrobbleEndPoint.addQueryItem("album", asAlbum);
  iScrobbleEndPoint.addQueryItem("number","1");
  iScrobbleEndPoint.addQueryItem("duration","200");
  
  iScrobbleDispatcher-&gt;get(QNetworkRequest(iScrobbleEndPoint));
  connect(iScrobbleDispatcher, SIGNAL(finished(QNetworkReply*)),
   SLOT(replyFinished(QNetworkReply*)));
  
  // QString Outside = iScrobbleEndPoint.toEncoded();
  
  qDebug()  &lt;&lt; "Received: " + 
    asUsername + " " + 
     asPassword + " " + 
      asArtist + " " +
       asTrack + " " + 
        asAlbum;
  
  qDebug() &lt;&lt; iScrobbleEndPoint.toString();
  
  }
  
  ScrobbleMedia::~ScrobbleMedia() {
  
  }
  </code></pre>
  
  <p>The associated header file looks like:</p>
  
  <pre><code>#ifndef SCROBBLEMEDIA_H
  #define SCROBBLEMEDIA_H
  
  #include &lt;QString&gt;
  #include &lt;QtNetwork&gt;
  #include &lt;QUrl&gt;
  #include &lt;QNetworkAccessManager&gt;
  
  
  
  class ScrobbleMedia : public QObject
  {
       Q_OBJECT;
  
  
  private:
  
  public:
  
      ScrobbleMedia(QString asUsername, QString asPassword, QString asArtist, QString asTrack, QString asAlbum);
      ~ScrobbleMedia();
  
  };
  
  #endif // SCROBBLEMEDIA_H
  </code></pre>
  
  <p>I'm currently building the application itself against a MinGW build of version 4.7.0 of the Qt libraries (included as part of Qt SDK 2010.05) under Windows 7 x86-64.</p>
  
  <p>Any assistance would be appreciated.</p>
  
  <p>Thanks in advance.</p>
