           Summary: [Qt] Implement QScriptEngine::newFunction() parts that
                    depend on QScriptContext
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore

As a start, a QScriptContext can be constructed in our custom JSObjectCallAsFunctionCallback, passing the function, thisObject, argumentCount, and arguments to it; e.g.

QScriptContext *QScriptEnginePrivate::createContext(function, thisObject, argumentCount, arguments);

This would be sufficient to implement QScriptContext::argument(), QScriptContext::argumentCount(), QScriptContext::callee(), and QScriptContext::thisObject().

Ideally retrieving the information could be delegated to JSContextRef, but it doesn't have the API for it currently. The above approach should cover 95% of the use-cases for QScriptContext wrt. QScriptEngine::newFunction(), however.
