VTK's widget not working in local mode

[yunYuntun]

Hello! I am a beginner in trame, and when I use VTK widgets such as the cross hair (vtk.vtkResliceCursorWidget) and use trame for LocalView, the widget loses its interactive function, but it does not occur when using RemoteView. Is this a problem with trame? How can I solve it?

It is actually a limitation of the current VtkLocalView, which relies on vtk.js. We are working toward a ~"full" parity using VTK/WASM, but that is still work-in-progress here, especially regarding widget support.
