@cdwilson Can you let me know the part number with which you encountered this crash?

[cdwilson]

311-330LRCT-ND (Yageo RC0402FR-07330RL)

(if this happens in the future, sometimes you may be able to get a hint from the name of the file in the trace rc0402fr-07330rl_symbol.png)

[eeintech]

@cdwilson Unfortunately I'm not able to reproduce this issue...

Can you do me a favor and copy-paste this code in a new file:

import PySimpleGUI as sg

layout = [[sg.Image(r'/Users/chris/Projects/Ki-nTree/search/images/rc0402fr-07330rl_symbol.png')]]

mainWin = sg.Window('Main Window',resizable=True).Layout(layout)

while True:
  event, values = mainWin.Read(timeout=0)

then run it. Does it crash the same way?

[cdwilson]

Yes, it crashes the same way. I wonder if it's a tkinter issue (I get a tkinter warning whenever I run kintree_gui.py). Let me see if there is a way to upgrade tkinter to a newer version and see if that fixes it. What tkinter version are you using?

@cdwilson This is what I have, from inside my virtual env:

$ python -c "import tkinter; print(tkinter.TkVersion)"
8.6

Update Tkinter then re-try?

[cdwilson]

Yeah, the crash was due to an old version of tkinter (8.5.9) shipped with Mac...

I use pyenv to manage python version installations (and I use anyenv to manage installation of pyenv, rbenv, etc.). I think pyenv just grabs the system installed tcl/tk framework which is pretty old.

After rebuilding python against newer tcl-tk installed via homebrew, everything works as expected, and I see the SnapEDA image:

Here are the steps I used to rebuild python:

$ brew install tcl-tk
$ env \
  PATH="$(brew --prefix tcl-tk)/bin:$PATH" \
  LDFLAGS="-L$(brew --prefix tcl-tk)/lib" \
  CPPFLAGS="-I$(brew --prefix tcl-tk)/include" \
  PKG_CONFIG_PATH="$(brew --prefix tcl-tk)/lib/pkgconfig" \
  CFLAGS="-I$(brew --prefix tcl-tk)/include" \
  PYTHON_CONFIGURE_OPTS="--with-tcltk-includes='-I$(brew --prefix tcl-tk)/include' --with-tcltk-libs='-L$(brew --prefix tcl-tk)/lib -ltcl8.6 -ltk8.6'" \
  pyenv install 3.9.1
$ python
Python 3.9.1 (default, Mar 17 2021, 07:34:15) 
[Clang 12.0.0 (clang-1200.0.32.29)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
>>> tkinter.TclVersion, tkinter.TkVersion
(8.6, 8.6)
>>> tkinter._test()

Sweet, should work now 😃
