    <p>Normally I would implement my own model inheriting from <code>QAbstractItemModel</code> directly and provide my own implementation for the presentation functions such as <code>data()</code> to handle the data storage container I give the model.</p> <p>If you have code duplication for using <code>QList&lt;T&gt;</code> and <code>std::vector&lt;T&gt;</code> then I would suggest converting one to the other by doing either:</p> <pre><code>QList&lt;T&gt; list = QList::fromVector(QVector::fromStdVector(vector)); </code></pre> <p>or the other way.</p> <pre><code>std::vector&lt;T&gt; vector = qlist.toVector().toStdVector(); </code></pre> <p>I'd do the latter but you can choose either.</p> <p>Based on your additional comments there are 2 paths of action you can take:</p> <p>Path 1:</p> <p>Implement <code>objectA</code> and <code>objectB</code> as follows: </p> <pre><code>class objectA : baseObject </code></pre> <p>and </p> <pre><code>class objectB : baseObject </code></pre> <p>where <code>baseObject</code> is: </p> <pre><code>struct baseObject { virtual std::string toString() = 0; }; </code></pre> <p>Probably easier to convert to string then anything else.</p> <p>Path 2 will basically involve inside the model using <code>std::vector&lt;boost::any&gt;()</code> as your data storage container, this way you can implement a single model subclassing <code>QAbstractListModel</code>.</p> <p>The thing that you have to consider that if your data storage container you can probably make common the data presentation you are limited at what you can do because <code>data()</code> function that will give your view the element has to return <code>QVariant</code> and it's limited at what you can construct it from.</p>

    1. COThe crux is that the base class that implements the boiler plate must be a template. I polished my question a little to better reflect my problem.

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.
