Passing a QList of objects to QML

[MoaMoaK]

Hi, I'm a bit lost right now.
I have a QML file that calls controller.getObjects() in order to get a list of custom objects.
The object controller is a QObject-derivated C++ object that is passed to QML through the context like so :
view->rootContext()->setProperty( "controler", controlerObj );
The getObjects() method is a C++ method with the macro Q_INVOKABLE declared in the Controller class. It's supposed to return a QVariant containing a QList<QObject*>.
The objects received are from different QObject-derivated classes (called Myclass1, MyClass2, ...). So I used QObject as the return type for getObjects().

This part seems to work fine : I have an array of MyClassX objects in QML and I can later access custom properties of thoses objects.

Then I wanted to add a common method for all classes MyClassX so I've added an abstract class AbstractItem that inherits from QObject and all classes MyClassX inherits from AbstractItem. Then I changed the return type of the method getObjects() to a QVariant containing a QList<AbstractItem*>. But what I receive (according to a console.log()) is QVariant(QList<AbstractItem*>) and NOT an array of AbstractItem objects.

I'm guessing I might need to look into registering my type so QML can use it into an array but:

1. I'm not sure if it's the solution to my problem
2. I can't find the doc page about it and how to do it properly in my case

So if someone could give me a hint about how to solve this (how to get an array of custom-class objects from C++ to QML), that would be nice.

Thx, MoaMoaK
