Answer 1

You need to register your pointer type like this

qRegisterMetaType<ClassA*>("ClassA*");

Answer 2

DataHandler is unknown type.

Q_PROPERTY docu says:

The type can be any type supported by QVariant

I'd try to encapsulate your DataHandler* in QVariant and make the property of type QVariant.

You could create the value containing your DataHandler pointer e.g like this:

const int DATA_HANDLER = QVariant::UserType +1;
//...
QVariant dataHandler( DATA_HANDLER, myDataHandlerPointer );
