[Python-Dev] Help/advice needed with JyNI issue #4 (Tkinter on OSX)

[Guido van Rossum]

Since this seems tcl/tk related your best bet is the tkinter mailing
list: https://mail.python.org/mailman/listinfo/tkinter-discuss

> The issue is rather strange in the sense that it works well on Linux, while the program hangs on OSX. Everything we found out so far was collected in the thread linked above. Briefly speaking, on OSX TCL/TK does not produce a particular event the loop is waiting for and does not display the window. However logging suggests that calls to TCL/TK API are identical between Linux and OSX runs, so we are really stuck here in finding out what is different on Linux (our current logging does not cover function argument values though).

Starting here, because in this list I see best chances to find someone who can help within the Python ecosystem. Next I would look for a TCL/TK forum or something.)
