OK I see. Yes I meant the QtQuickVTKRenderWIndow. I thought all Cpp classes are automatically wrapped to python classes and are then published to use them with pip.
I also have seen vtkmodules.qt.QVTKRenderWindowInteractor. But it was the same GLEW could not be initialized: Missing GL version error here. I was not even able to show the cylinder, but that is another thing.
