QWebChannel pass QObject from JS

[kDohmen]

Hello,

is it possible with a webchannel to pass objects (QObject derived) in js?

To explain it, i habe something like this:
c++

class B;
class A : public QObject
{
    Q_OBJECT
    public slots:
        void pass_b(const B *b) {...}                     // do something with b
}

class B : public QObject
{
    Q_OBJECT
}

js

function someFunc()
{
    var b = {};                                  // ignore how I got a b-object here ;)
    channel.objects.a.pass_b(b);
}

As I see, a Json-object will be delivered. But when it comes to argument interpretation (QMetaObjectPublisher::invokeMethod) the json-object is passed to a QVariant and is checked if the needed parameter for the called method is QVariant or if the QVariant-object can be converted to the needed type. But a json-object can not be converted to a QObject. There is no check with wrappedObjects if the object is already known.

PS: I used the qtwebchannel module from the qt5 github repo in dev-branch.
