Don't know about that one.

Here are two "answers" re: MacPython & Tk I culled from previous
messages. Maybe they'll help. Also, you should tune into the
PythonMacSIG (see: http://www.python.org/pipermail/pythonmac-sig/ and
http://www.python.org/mailman/listinfo/pythonmac-sig. Good people hang
out there who can give lots of answers.
(1) Tk and setting the right Mac path
Thanks to Ben Coburn and Richard Gordon I was able to get Tk to work on
my mac. I fixed the problem by placing the following path's in the
Is there a reason that these two paths are not automatically set during
the installation. I was a bit frustrated when I couldn't get through
the example code in Chapter 1 of Learning Python (pg 23 has a Tk
(2) How to: Tk on Mac
Programming graphical user interfaces (GUI's) with the Tk-toolkit and
MacPython is easy and makes fun. But
unfortunately if you try the simplest demo script with a fresh
installed MacPython you will get the following
Traceback (innermost last):
1.5.2c1:Demo:tkinter:matt:animation-w-velocity-ctrl.py", line 1, in ?
from Tkinter import *
File "MacHD:Python 1.5.2c1:Lib:lib-tk:Tkinter.py", line 8, in ?
import _tkinter # If this fails your Python may not be configured for
ImportError: No module named _tkinter
The reason therefore is a bug in the installer of MacPython1.5.2c1: It
puts the shared libs »_tkinter.CFM68K.slb« as well as
»_tkinter.ppc.slb« in the folder »TK« which is in the folder »Imaging«
in the folder »Extensions«. You have to put one of them (or both ) in
the folder »PlugIns« which is in the folder »Mac«.
And also the fresh standard installation has no path to
»$(PYTHON):Lib:lib-tk«, you have to add that manually with the program
Unfortunately there is also a bug within the interpreter. Calling
»Tkinter« from the interpreter interactivetely freezes them. You can
only run Tk-based Python scripts by typing them in your editor and
running them by dropping over the interpreter or saving them as Python
files and starting them by doubleclick.
And you never can run Tkinter based scripts from the IDE. But this
behaviour is documented.
