Using Blur Behind on Windows with Qt 5

Back in September 2009 Jens Bache-Wiig [blog.qt.digia.com] wrote an article called Using Blur Behind on Windows [blog.qt.digia.com]. At the time, I think it was posted in the Labs section, but now, the only remains I can find is the the given blog link. I have the original source code and I have been using it with Qt 4. Now, I want to upgrade to Qt 5. Have anyone rewritten this source code for Qt 5? Or better yet, are there better and simpler ways of doing this with Qt 5. For those who don’t have the original article and source code; the goal is to extend the “glass”-like window borders into the window itself, using the Aero effects on Windows.
