Editing Delegates

In the previous two episodes we looked at Qt's support for rendering items in the model/view framework.
In this episode we will turn our attention to custom delegates for editing items.
In the KDAB gift shop we will receive a ready to use delegate for choosing items with a combo box.

About the host:
The video is presented by Jesper Pedersen, who started with Qt back when Qt was widgets only and the version was 1.44, which gives him 21 years of experience with Qt. Since 2000 he has taught almost 100 Qt classes, ranging from Qt Widgets to QML. Heck, Jesper even taught a few classes on QTopia Core - Trolltech's initial attempt at creating a phone stack. Today Jesper holds a fancy business title, but that doesn't prevent him from coding both in his job and in his spare time.
