We are now going to put QML aside for a little while. It's time to go back to C++ and learn about the most important class in Qt, QObject. QObject implements a huge number of features: properties, events, signals and slots, automatic memory management and much more. In this module we are going to explore how they work and how they map to all the QML knowledge that we have built so far. We'll kickstart this module by discussing what the parent/child relationship entails for QObjects and how Qt's Meta Object System works in order to "enhance" what C++ gives us in terms of object introspection and reflection. The example code showcased in this video is available here: https://github.com/KDAB/kdabtv This 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.
