Introduction to Qt Widgets (Part 54) - Model/View Concepts

Описание: After two episodes talking about the item versions of lists, tables, and trees, we now turn our attention to the model/view version of that story.

Using model/view offers a great opportunity to do a separation between business logic and presentation.

In this episode we will start the journey from 10.000 feet, learning how each of the parts fits together.

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.
