Hi @efahl, thanks for replying.
Path.glob returns Path objects, so I’m not sure what you mean. That code works fine on my computer.
To be clear, I’m a very basic VTK user. I know very little of C++ and don’t know how the wrappers work. I was just curious about whether this had ever been discussed, or whether some of the main developers thought it would be a good feature to add. I don’t think this is an essential feature or it solves and VTK problems. I asked something similar on the Slicer forum and I was suggested to extend my question to VTK and PythonQt. And here I am, because I thought it would be helpful for the three libraries to have pathlib support. I understand that if this would need a big effort, it’s just not worth it.
So to answer your question, I haven’t made the list of touch points. I wouldn’t know where to start! I just searched for SetFileName but got overwhelmed by the results. I think there’s really not much I can do to help here, unfortunately.
