Hi,

Is there context-sensitive help (something like IntelliSense) available for Slicer classes when editing Python or C++ code?

Thank you

Rudolf

Yes, but not with static analysis (we can revisit that after VTK9 upgrade in a few weeks) but with a running Slicer. If you put a breakpoint in the function that you want to edit and you use a good IDE (such as PyCharm) then you should be able to get auto-complete and documentation.

Or, you can use [Jupyter](https://github.com/Slicer/SlicerJupyter) to develop new functions and - you get syntax-highlighting, autocomplete, and API documentation, etc.
