    <p>I have created a ListView model based on QAbstractListModel similar to this <a href="http://doc.qt.digia.com/4.7-snapshot/declarative-modelviews-abstractitemmodel.html" rel="nofollow">example</a>. The problem is my ListView doesn't show all rows, but only those which are initialy visible. So when I scroll (or flick) down theres only black space. ListView has count == 0 but it should have count == 10, since I've added 10 elements.</p> <p>My class contains the necessary mothods to update the model rowCount</p> <pre><code>// needed as implementation of virtual method int rowCount(const QModelIndex &amp; parent) const { return standings.size(); } int rowCount() { return standings.size(); } void addStanding(const Standing &amp;st) { beginInsertRows(QModelIndex(), rowCount(), rowCount()); qDebug() &lt;&lt; "row cnt: " &lt;&lt; rowCount(); standings &lt;&lt; st; endInsertRows(); } </code></pre> <p>I also update the ListView model</p> <pre><code>rootContext = (QDeclarativeContext*)(viewer-&gt;rootContext()); rootContext-&gt;setContextProperty("myModel", &amp;sm); </code></pre> <p>QML code</p> <pre><code>ListView { id: raceList objectName: "standingList" y: header.height width: parent.width height: parent.height - header.height clip: true model: myModel delegate: rowComp } Component { id: rowComp SessionRowDelegate { } } </code></pre> <p>I would also like to mention that this works fine with a static model. <strong>How to make ListView display all items all the time and not only if visible to user?</strong></p> <p>SessionRowDelegate</p> <pre><code>Rectangle { id: rowbg width: parent.width height: 34 * (1 + (parent.width - 360) * 0.002) // contains other elements with height not exceeding rowbg's height // ... } </code></pre>

    2. COHow does ure SessionRowDelegate look like? Most importantly, have all the rows of the list view uniform heights? ListView won't work properly if not.

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.
