If one has QObjects living in C++, how does one manage one's lifetime, when these objects are exposed to QML? Is the QML garbage collector allowed to reclaim them? What happens if they're still needed in C++? Or, on the other hand, what happens if one doesn't delete them from C++, expecting them to be deleted by QML instead? In other words, who owns what? Let's find out, in this video.

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.
