Q_ENUMS as property variant index

Hello all!
I have the following problem: i declare enum in C++ and share it to QML context

Code:

---

class TestClass{
        Q_OBJECT
        Q_ENUMS(testEnum)
    public:
        enum testEnum{
            Low = 0,
            Mid = 1,
            High = 2
        };
    }

---

Code:

---

qmlRegisterUncreatableType<TestClass>("CppImport", 1, 0, "TestClass", "NOT MAY CREATE");

---

In QML I’m trying to create property variant:

Code:

---

import QtQuick 1.1
    import CppImport 1.0
 
    QtObject{
        property variant dict:{
            TestClass.Low: "Low string",
            TestClass.Mid: "Mid string",
            TestClass.High: "High string",
    }
    }

---

I have this error:

Code:

---

Expected token `:'  TestClass.Low: "Low string",

---

It is a bug? or I do not quite understand QML? Q_ENUMS should be represented as integers in QML. how to get around this error?

My Qt version: 4.8.4. Sory for bad english.
