Introduction to Qt/QML (Part 49) - Creating New Elements from C++
In the previous videos, we've seen how to export individual existing objects from C++ to QML. In this video, we'll show something related, but conceptually quite different. How do we expose C++ classes to QML and let QML create their instances? To keep our lives simple, we'll start by exposing a non-GUI class; the next video will deal with those.
The example code showcased in this video is available here: https://github.com/KDAB/kdabtv

About the host:
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.
