I configured the vtk environment for my new computer today, so I downloaded the latest vtk version and I found that the code (base on 8.1) wrote before doesn’t work,  
it shows : qvtkwidget.h no such file or directory

And i checked in Cmake-gui the Qt-group option is checked, but still no qvtkwidget.h. I search the vtk  
resource files and there is also no qvtkwidget.h.

Has it been replaced by some new Class, and how can I change the previous object which initialized by qvtkwidget ?

Thanks!

I have the same confusion about QVTKWidget until I read this post.

Hope this helps! 🙂
