    <p>I also found this very tricky, and remember it took a long while to work out. Eventually in desperation I wrote this handy function:</p> <pre><code>#include &lt;QDebug&gt; #include &lt;QDir&gt; #include &lt;QList&gt; #include &lt;QUrl&gt; #include &lt;sstream&gt; using namespace bb::data; using namespace std; void listContents(QDir &amp;src, int depth=0) { // You app's dirs can be symlinked into libraries, so the depth can go very deep. // We limit it. if (3&lt;depth) return; QListIterator&lt;QFileInfo&gt; entries(src.entryInfoList()); std::stringstream spaces; // If you want to indent files by depth // for (int i=0; i&lt;depth; i++) { // spaces &lt;&lt; ' '; // } while (entries.hasNext()) { QFileInfo entry = entries.next(); QString canpath = entry.canonicalFilePath(); QString relpath = src.relativeFilePath(entry.fileName()); if ((relpath == ".") || (relpath=="..")) { continue; } if (entry.isDir()) { QDir subdir(canpath); if (!(subdir==src)) { listContents(subdir, depth+1); } } else { qDebug() &lt;&lt; spaces.str().c_str() &lt;&lt; canpath.toUtf8().data(); } } } </code></pre> <p>To use it, you must first strip the <code>/data</code> directory from your <code>QDir::homePath()</code>:</p> <pre><code>QString appFolder(QDir::homePath()); qDebug() &lt;&lt; "appFolder = " &lt;&lt; appFolder; appFolder.chop(4); QDir listSource = appFolder + "app/native"; listContents(listSource); </code></pre> <p>Thereafter, just check the logs to find the proper path to your database file.</p> <p>Note though that, if you want to write to the database, you should copy it from the <code>app/native</code> directory to the <code>data</code> directory.</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
