Cannot find elements when using Ranorex UI test tool.

When I use Ranorex (a Windows test tool) to track the UI component written using Qt for C++ I cannot see the elements. I have included two images of the Ranorex Spy tool tracking some components of the qtDemo=>Config Dialog example for both Qt-4.6.3 and Qt-4.8.4. How you can see from Ranorex-Spy-with-qt.4.6.3-finding-elements.png image I can find the elements in the qt-4.6.3 qtDemo=>Config Dialog example. On the contrary the Ranorex-Spy-with-qt.4.8.4-not-finding-elements.png image shows that I cannot find the element with the same qtdemo =>Config Dialog example in qt-4.8.4.

We use QT Accessibility with Ranorex to track the components of our application and we just moved from Qt-4.6.3 (which we could see the elements) to Qt-4.8.4 where we cannot see the elements any more.

Is this a bug or just Qt is moving away from this?

Thanks
