When building master with VTK\_MODULE\_ENABLE\_VTK\_GUISupportQtOpenGL I’m getting the following error (I have Qt 5.12.0 if that matters):

> **src/VTK/2019-11-24/GUISupport/QtOpenGL/QVTKWidget2.cxx:488:21:**  **error:**  **no member named ‘Frame’ in ‘QGLWidget’**

I’ve also been seeing this. @utkarshayachit @mwestphal Thoughts? Is this fallout from the switched around class hierarchy here?

It’s not, this class has been completely removed from master in my MR.  
This line was actually short lived, it was added late 2019 by @ken-martin in this MR :

Ah, it was removed just a few weeks ago. I should have made more noise earlier, but I didn’t need the class at the time, so I just pushed it under a rug.
