[Pyobjc-dev] PreferencePanes in python

[Ronald O. <ron...@xs...>]

I think I have found a way to build preference panes in Python.

The following code seems to work just fine for loading and initializing 
a Python interpreter. The attached archive contains a complete (and 
rather lame) preference pane, run the shell-script to compile the 
Objective-C file and copy the prefpane to ~/Library/PreferencePanes to 
test.

Both the script and the ObjC code require a framework install of 
python, but modifying it for a normal python install is pretty trivial 
(as long as there is a libpython.{so,dylib,a}, Apple's python won't 
work).

Did I mis anything important? I know the PYTHONPATH is not correct, 
I'll look into that later.

BTW. I couldn't get bundlebuilder to build the bundle for me, it always 
adds the shell-script wrapper which isn't needed here. Furthermore the 
output always has a '.app' suffix. More to look into...
