[Interest] Using Non-QObject-derived types in Javascript

[Gav Wood]

Hi,

I'm working to extending some functionality to be used by the
Javascript as part of a QWebView page. I need to be able to pass
around some non-QObject derived classes (actually a big-integer class)
as arguments & return types of the APIs I expose. This worked find
when doing something similar in QML/QtQuick. Is it going to be
possible here?

I've tried

qRegisterMetaType<NonQObjectType>("NonQObjectType");

and

Q_DECLARE_METATYPE(NonQObjectType)

But then given a class:

class ExposedAPI: QObject
{
Q_OBJECT
public:
Q_INVOKABLE NonQObjectType foo();
Q_INVOKABLE QString bar(NonQObjectType _t);
Q_INVOKABLE QString baz();
};

If I expose with:

addToJavaScriptWindowObject("api", new ExposedAPI, QWebFrame::ScriptOwnership);

then the JavaScript:

window.api.bar(window.api.foo())

does nothing whereas:

window.api.baz()

works as expected.
