[Interest] Subclassing QQmlComponent for use in QML

[Gian Maxera]

Not sure want you need.
If you just need to create your objects from QML, it’s not mandatory to extend from QQmlComponent but from QObject.

So, if you create a C++ class derived from QObject called:
class MyNewQML : public QObject 

and you register is with qmlRegisterType

you can write into QML:

MyNewQML {
  ….
}

Ciao,
Gianluca.
