The tutorial is building an elaborate UI around a QMap. It doesn't use
structured data, and it doesn't use model/view (which the dedicated
addressbook example in itemviews does).
It's not a good way of building an application, and the individual APIs
for creating layouts, dialogs, or import/export are explained well
enough in other examples.
