Qt Header on QListView
Introduction
The QListView widget is part of the Model/View programming mechanisms of Qt. Basically, it allows to display items stored in a Model under the form of a list. In this topic we will not get deep into the Model/View mechanisms of Qt, but rather focus on the graphical aspect of one View widget: the QListView, and especially how to add a header on top of this object through the use of the QPaintEvent object.
