I have tried to run Tkinter in an extension. Its not included as a package in the distribution and doesn't work without manual download and install into correct place.

However I suspect your problem is you want the UI to remain open while inkscape calls its extension and gets the results back, and inserts them into the current scene.

So I don't think its possible in current design. It used to be possible but I have asked the list in eth past and no one has been able to help me.

I think you're out of luck.

Hi guys, I'm quite new with Inkscape so forgive me if the question is trivial.
I'm developing an extension using Tkinter,it works well but the dialog is modal and I cannot do anything else with Inkscape while the extension is open. Is there a way to avoid this problem?
Thanks a lot.
