The python.cmake for Windows explicitly excludes tkinter through set IncludeTkinter=false.

The [python.cmake ](https://developer.blender.org/diffusion/B/browse/master/build_files/build_environment/cmake/python.cmake$45) for Windows explicitly excludes `tkinter` through `set IncludeTkinter=false`.

That’s a bit disappointing I will have to find a work around with the script

Closing.

Is it to encourage people to use bpy and Blender native interfaces ? or some other technical reason ?

(I'm running into the same limitation and would like some closure on the idea)

@TonyG as far as I'm aware tkinter GUI's aren't compatible with Blender's main loop, as in - it's not practical to use tkinter unless Blender is locked (does not refresh), the tkinter GUI can be interacted with, then it can be exited and return to Blender's main loop.
Since this is quite limiting and Blender has it's own GUI, it seems like bundling tkinter is of limited use and certainly won't integrate well with Blender interfaces.

One other down side is tkinter doesn't support Wayland. While this alone isn't a deciding factor, it's a down side if add-ons depend on libraries that aren't supported on all platforms.

@ideasman42 Thanks for taking time to clear that out, it makes sense.

You are correct about the use case : my add-on already uses Matplotlib which also freezes Blender while its window is open, tkinter would be no different.
That's ok for me though because I'm presenting data to the user for validation = no need to interact with Blender at the same time.
I'll figure something else ^^
