How can I identify the version of Tk that I'm running? I installed
IDLE using the download of Python 2.5.2 from Python.org.

Hmmm. Are you using the system installation of Tk (8.4.7)?
I'd install a later version of Tcl/Tk from here: http://www.categorifiedcoder.info/tcltk/
. Try 8.4.19.
There was some weirdness with the Preferences menu before--with
certain versions of Tk the menu item appeared twice--so I wrote a
patch that set it to appear only once, which Ronald committed. I
think the bug doesn't exist with Tk 8.4.7. However, that version is
so old that I'm disinclined to offer another patch.

Look in /Library/Frameworks. If you don't see Tcl.framework and
Tk.framework, then you are most likely running the Apple-installed
version (8.4.7) installed in /System/Library/Frameworks.
As I said, this version is very old (c. 2005?). 8.4.19 from the link
I gave you before will work with Python.

Subject: [Pythonmac-SIG] PyObjC tutorial without Xcode
Hi,
I am familiar with python already, and I am familiar with the mac as a
user, but otherwise have no mac development experience. I'm keen to
learn pyobjc and write native mac/python GUI apps.
I'm currently having problems with outdated-ness and inaccuracies with
both tutorials* I can find on PyObjC, and I think it could be simpler
if I could find a tutorial that didn't involve Xcode (and the xcode
python support seems spotty). Can anyone point me in the right
direction please? I'm happy to use a plain old text editor and
run/debug from the command line, and also I'd rather leave obj-C alone
if possible. I accept that I'll need to use interface builder (which
seems like a great app, anyway).
Is this possible? If so - pointers would be gratefully received.
Thanks,
Craig Marshall

I sent this just to Craig, but figured I should probably send to the
group in retrospect - at least this way something'll be online in
the pythonmac-sig archives...
Below my signature is a sample script demonstrating a really minimal
use of pyobjc. This is meant to be run from the command line, and
uses the BTop2 framework from Perfectly Scientific. You can
download that framework for free, but it won't do much if you don't
have the hardware!
Not exactly a tutorial, but darned simple for sure... I can't
remember if that __getattr__ thing ever worked... I don't think it
did. The Exception thing is _way_ useful (as indicated in the
comments there). The standard exception messages you'll get while
using pyobjc are close to useless.
I'll add also that I'd not be averse to chipping in to a non-Xcode
pyobjc tutorial online somewhere. I'm not terribly self-motivated
on that, but would do if someone asked for more.
Cheers,
Dav

Hi all again,
Below my signature is a sample script demonstrating a really
minimal use of
pyobjc. This is meant to be run from the command line, and uses
the BTop2
framework from Perfectly Scientific. You can download that
framework for
free, but it won't do much if you don't have the hardware!
Thanks for sending the above dav, I think I'm more interested in
trying to get a very basic GUI up and running, which from the look of
it your script doesn't handle..
I tried another tactic. I went through all the example folders that
the xcode 3.1 installation put on my hard drive
(/Developer/Documentation/Python/PyObjC/tutorial/ specifically) and
found again the official pyobjc tutorial. My new tactic is to start
with the final piece of code there (step 12), build and run it and
then play with it until I know how it works.
The problem is, when I build it and run it (out of the box!), it
doesn't work (cue hair-pulling sounds). I open a terminal, tell it to
build (python setup.py py2app), then tell it to run (open
dist/CurrencyConverter.app), and it gives me a dialog box with an
error inside:
CurrencyConverter Error
An unexpected error has occured during excution of the main script
ImportError: No module named Foundation
Open Console or Terminate
So - I'm beginning to think either these are the useless errors that
dav talked about and that I need to somehow shoe-horn the useful
exception code into the py2app build instructions, or that it really
can't find the Foundation module. I would have thought py2app could
find and insert the bits and pieces it needs just from the import
statements, or do I have to declare that I want to use Foundation in
the setup.py somehow?
A third possibility is that I've somehow broken my setup - how else
could a tutorial that came with the latest xcode not work out of the
box?
I'd be very grateful if someone can point me in the direction of at
least a very small working pyobjc GUI app that works out of the box
with modern software ....
Craig
