[PyQt] Implementation of the QQuickFramebufferObject

[Rostyslav Lyulinetskyy]

Hi,

I am trying to port my c++ code to python and I am integrating a custom 
OpenGL rendering with Qt Quick via QQuickFramebufferObject (as described 
here: 
https://blog.qt.io/blog/2015/05/11/integrating-custom-opengl-rendering-with-qt-quick-via-qquickframebufferobject/)
Everything works well in c++, but for various reasons I need to port 
this to python and it doesn't seem to work. The virtual function 
createRenderer() in the QQuickFramebufferObject must be overridden so 
one can return a new renderer, but for some reason this function is not 
even called when using PyQt.

Is it even possible to override this virtual function from python? Am I 
missing something?

Here is a small example to replicate that the createRenderer() function 
is not called:
