How to make a class in Qt both scriptable and serializable?

Question

I'm trying to write a class with two basic characteristics:

• It needs to be scriptable - the class contains a number of properties and methods decorated with Q_INVOKABLE that are exposed to scripts.
• It needs to be serializable so that it can be registered with qRegisterMetaTypeStreamOperators() for storing in QVariants.

As far as I can tell, I need to derive from QObject in order to make the class scriptable. However, in order to register the class with qRegisterMetaTypeStreamOperators(), it seems like the class needs to have a default copy constructor - something a QObject-derived class cannot have.

Is there any way to achieve both goals?

Answer 1

You can have scriptable objects not derived from QObject but it's more work. It's discussed here
