Type casting in QtScript.

[michael]

I have a class hierarchy

@
class A
{

public:

QList<A*> list()
{
     return _list;
}

protected:

QList<A*> _list;

};

class B : public A
{
B()
{
_list.push_back(this);
}
};
@

Both classes are not QObject descendants.

I expose both classes to QtScript using QScriptable classes and QScriptEngine::setDefaultPrototype() method. Method list() is exposed to QtScript.

When I call list() from JavaScript I get a collection of pointers to class A, but among them I have pointers to class B. How I can cast those pointers to B* in JavaScript? Or maybe it is possible to change A* prototype to B* prototype? Maybe it is possible to write some function to do that in C++.

Does somebody have any ideas how to solve the problem?

Thanks,
MIchael
