python vtk: how to import QVTKOpenGLNativeWidget
Solution 1:
No, you cannot import QVTKOpenGLNativeWidget in Python because the Python bindings for VTK doesn't have that class (as of VTK 8.2.0). A quick grep doesn't find it anywhere in the VTK python package. I grepped /usr/lib64/python3.6/site-packages/vtk* (which is where I have python3-vtk installed) recursively for QVTKOpenGLNativeWidget and grep didn't find anything.
