I need to sync widgets’ actions that are in multiple renderwindows together. Upon first inspection, vtkWidgetSet seemed to be the right choice for this but as I understand now, the implementation hasn’t been touched in years and basically only barely works for a single widget type (vtkParallelopipedWidget) and it completely doesn’t work in Python. [Related GitLab issue](https://gitlab.kitware.com/vtk/vtk/-/issues/17079)

Any advice on doing this in python? I thought about making a custom callback similar to [this example](https://gitlab.kitware.com/vtk/vtk/-/blob/v9.2.6/Examples/GUI/Qt/FourPaneViewer/QtVTKRenderWindows.cxx#L37-113) which ties 3 instance of vtkResliceCursorWidget and vtkImagePlaneWidget together and generalize it for infinite number of widgets and other types of vtkAbstractWidget but I’m not entirely sure!

Thanks in advance.
