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.
