  # https://forum.snapcraft.io/t/the-tcltk-launch-launcher-fix-tcl-tk-applications-in-the-snap-runtime/11740
  source: https://github.com/Lin-Buo-Ren/tcltk-launch.git
  source-tag: v1.0.0
  plugin: dump
  stage:
    - bin/*

then add bin/tcltk-launch to the command chain to launch the application:

apps:
  _app_name_:
    adapter: full
    command: bin/_app_executable_
    command-chain:
    - bin/tcltk-launch

This launcher depends on The debian-multiarch-triplet-provider-launch launcher: Enable DEBIAN_MULTIARCH_TRIPLET-like environment variable in the snap runtime , refer the topic to integrate it into the snapcraft recipe.

@Lin-Buo-Ren I’m having trouble with this. My snap seems to work perfectly except that it does not accept keyboard input when assigned to foreign scripts. This is even the case in devmode. Do you know why this is?

[Lin-Buo-Ren]

First of all, apologies for the ignorance.

@clockback

My snap seems to work perfectly except that it does not accept keyboard input when assigned to foreign scripts.

Might be an input method framework compatibility issue or a XCompose(5) compatibility issue. Which foreign script you’re using?

I was trying to write in Cyrillic, but I’m pretty sure it didn’t work for other character sets as well. I’m not working on this project anymore, so probably don’t worry about it, unless someone else has problems.

[Lin-Buo-Ren]

Thanks for your input! I’ll definitely check it out after knowing how to reproduce them.

@admins Please set this topic as a wiki, thanks!

Done, and thank you for all the fantastic additions over the last couple of days!

Hi! I have been trying to replicate your success with tkinter in a snap environment and am getting stuck on a “Module not found” error. I believe I am doing something incorrectly.

File “/snap/ocrmypdfgui/24/usr/lib/python3.8/tkinter/init.py”, line 36, in import _tkinter # If this fails your Python may not be configured for Tk ModuleNotFoundError: No module named ‘_tkinter’

My Snapcraft.yaml can be found here:

alexanderlanganke/ocrmypdfgui/blob/main/snapcraft.yaml

Any help would be appreciated. Thanks in advance!
