    <p>After reading a number of different sources of information (most of which were contradictory), I've found that the following results in a working solution - albeit with a cosmetic issue in the debugging output that doesn't seem to affect operation (<code>Object::connect: No such signal QNetworkReplyImpl::finished(QNetworkReply*) in ../AudioPlayer/scrobblemedia.cpp:29</code>):</p> <p>In <code>scrobblemedia.cpp</code>:</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) { QByteArray iDataSink; QEventLoop iLoop; QString KEndPointURL = "http://lastfmstats.livefrombmore.com/universalscrobbler/scrobble.php"; QUrl iScrobbleEndPoint(KEndPointURL); 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"); QNetworkAccessManager iScrobbleDispatcher; QNetworkRequest iScrobbleRequest(iScrobbleEndPoint); QNetworkReply *iScrobbleReply = iScrobbleDispatcher.get(iScrobbleRequest); QObject::connect(iScrobbleReply, SIGNAL(finished(QNetworkReply*)), &amp;iLoop, SLOT(quit())); iDataSink = iScrobbleReply-&gt;readAll(); qDebug() &lt;&lt; "Received: " + asUsername + " " + asPassword + " " + asArtist + " " + asTrack + " " + asAlbum; qDebug() &lt;&lt; iScrobbleEndPoint.toString(); iLoop.exec(); } ScrobbleMedia::~ScrobbleMedia() { } void ScrobbleMedia::replyFinished(QNetworkReply*) { } void ScrobbleMedia::reallyDone() { qDebug() &lt;&lt; "We've probably successfully Scrobbled..."; } </code></pre> <p>In <code>scrobblemedia.h</code>:</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(); private slots: void replyFinished(QNetworkReply*); void reallyDone(); }; #endif // SCROBBLEMEDIA_H </code></pre> <p>Thanks to everyone for their help. </p> <p>Hopefully this code will serve as a useful template for others, in the future.</p>

    1. COWhere exactly the reallyDone() slot is called? I don't see it in the code. Why do you need an event loop? If it's not a multi-threading application, then using a separate event loop is unnecessary at least or maybe even dangerous. And finally, your issue isn't "cosmetic". You get it because you're trying to connect to a non-existent signal `finished(QNetworkReply*)` in iScrobbleReply. It only has the finished() signal with no parameters. It's the QNetworkAccessManager that has the finished() slot with a QNetworkReply* parameter. That's why your quit() method will never get called.

    2. COreallyDone() isn't called anywhere - it's just left over from a previous attempt at getting things to work. The event loop idea was suggested at http://stackoverflow.com/questions/2572985/how-can-i-use-qt-to-get-html-code-of-the-redirected-page, and seemed to work in my case.

    3. COWith that in mind, I've removed `reallyDone()`, and defined `void finished(QNetworkReply*)`, in addition to providing a stub implementation of it. The code itself still works (I can see HTTP requests in Wireshark), but handling the "bottomless slots" problem cleanly is something for later, since I've got to leave to go somewhere soon.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
