    <p>I'm running into difficulty retrieving values from a service call that is supposed to return an array of integers. The method call in the interface xml file is defined as:</p> <pre><code>&lt;method name="PurpleFindBuddies"&gt; &lt;annotation name="org.qtproject.QtDBus.QtTypeName.Out0" value="QList&amp;lt;int&gt;"/&gt; &lt;arg name="accountId" type="i" direction="in" /&gt; &lt;arg name="screenName" type="s" direction="in" /&gt; &lt;arg name="buddies" type="ai" direction="out" /&gt; &lt;/method&gt; </code></pre> <p>qdbusxml2cpp generates the following method:</p> <pre><code> inline QDBusPendingReply&lt;QList&lt;int&gt; &gt; PurpleFindBuddies(int accountId, const QString &amp;screenName) { QList&lt;QVariant&gt; argumentList; argumentList &lt;&lt; QVariant::fromValue(accountId) &lt;&lt; QVariant::fromValue(screenName); return asyncCallWithArgumentList(QLatin1String("PurpleFindBuddies"), argumentList); } </code></pre> <p>I have also added </p> <pre><code>Q_DECLARE_METATYPE(QList&lt;int&gt;) </code></pre> <p>at the top of the generated .h file. And in main.cpp, I'm making the following call</p> <pre><code>QDBusPendingReply&lt;QList&lt;int&gt; &gt; buddies = pidgin-&gt;PurpleFindBuddies(accountId, "email@gmail.com"); buddies.waitForFinished(); if ( buddies.isError() ) { qDebug() &lt;&lt; buddies.error(); return -1; } qDebug() &lt;&lt; buddies.argumentAt(0).toList().size(); </code></pre> <p>When I launch the program, I can see from the enabled debug output that I am getting results, as shown below, but the qDebug() line prints 0. I cannot figure out how to correctly retrieve the results.</p> <pre><code>QDBusConnectionPrivate(0x138fbc0) got message reply (async): QDBusMessage(type=MethodReturn, service=":1.135", signature="ai", contents=([Argument: ai {859}]) ) </code></pre> <p>What am I missing? Any assistance would be greatly appreciated.</p>

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.
