I've used Python for years, but I am fairly new to the Mac, wxPython,
and py2app.
I got a simple wxPython test app bundle working fine (it just puts an
unpopulated frame on the screen) . The same bundle runs on 10.5
Intel, 10.4 PPC, and 10.3 PPC.
So now I am attempting to package a more complex app that was being
developed by a recently departed co-worker. This app makes use of XRC
resources, which seems to be the right way to do things.
The app runs fine in my development environment. However when I
package it with py2app, calls to XRCCTRL() return None instead of a
component instance. The XRCID() method that XRCCTRL uses is returning
an Id, but the window.FindWindowById() is returning None.
Here is my environment:
OSX 10.5.4
MacPython 2.5.2 (insta
wxPython 2.6.4.0 (also tried 2.8.8.0 with same results)
py2app 0.4.2 (dev version needed for correct handling of setuptools
namespace packages)
I suspected that something wasn't being included in the bundle, so
I've tried adding all of the following via the py2app "packages"
option:
'wxPython',
'wx',
'wx.build',
'wx.lib',
'wx.py',
'wx.tools'
No joy. The bundle got significantly bigger, but I still get the same problem.
I'm stumped. I've scoured the Internet, but I can't find any
references to a similar problem.
Can anyone shed some light on this?

Yep. That was it. It couldn't load the .xrc file.
However, the problem wasn't an incorrect path. My co-worker had used
os.dirname(__file__) to load the .xrc files that are stored alongside
the .py files. This works fine until py2app bundles both files into
site-packages.zip.
I modified the .xrc loading code to use __name__ with
pkg_resources.resource_string() and all is well.
Thanks!
