[issue26673] Tkinter error when opening IDLE configuration menu (Tcl/Tk 8.6)

Terry J. Reedy added the comment: I would like to change the code a bit more (like using IntVar for size everywhere), but I don't want to do so without tests. The problem is that tk variables and font functions require a root window and none of the linux buildbots allow that. (They all run

Terry J. Reedy added the comment: Anyone seeing problem: In /Lib/idlelib/configHandler.py, about line 685, in "if size < 0:", change '<' to '<='. Remove the workaround of overriding 'TkFixedFont' with 'courier'. Does this fix the problem? -- ___

Terry J. Reedy added the comment: Mark, changing the default font from Courier to TkFixedFont has introduced or exposed a bug in any of IDLE, tkinter, or tk 8.6.4 on Linux. The result is that trying to open the configuration menu fails with TclError. What do your think is the best solution?

Terry J. Reedy added the comment: #24745 changed the default fixed font from Courier to TkFixedFontin 3.5.0, 3.4.4, and 2.7.11 when using tcl/tk 8.5+. On some OSes, the latter is not Courier and looks much better. I don't know why the two behave differently on some systems. Since this is

Petr Viktorin added the comment: I can reproduce this with Python 2.7.11 and somewhat recent build from hg default (3.6.0a0) on Fedora 23. Putting these lines in my personal config-main.cfg solves this:: [EditorWindow] font= courier idlelib/config-main.def has a different default::

Terry J. Reedy added the comment: I should have thought of .idlerc as being a possible problem. The usual fix is to delete its contents. For this tracker, exiting with a traceback is a behavior issue; a crash is something worse, a core dump or whatever the MAC equivalent is. .idlerc should

wysaard added the comment: I just fixed this problem. In my ~/.idlerc/ folder there was no `config-main.cfg` so I created it and used the settings found here: https://svn.python.org/projects/python/trunk/Mac/IDLE/config-main.def After doing that everything worked fine again. I'm not sure

wysaard added the comment: In the screen of `About IDLE` it shows "Tk version 8.6.4". It used to work, as least since last september (when I installed this) I've had no problems. I assumed reinstalling would solve it but that did nothing. I've removed the entire python package, made my package

New submission from wysaard: I'm using Python 3.5.1 on Arch Linux. I've restalled the python package which provides IDLE, and the tkinter package which is used by IDLE, but to no effect. My problem is this: When in the menu at the top in IDLE, I click on Options -> Configure IDLE, the menu
