I added the hook and found that it gets triggered whether or not PYTHONPATH
has the wxPython directory in it. Here is the full comment from
wxversion.py:
"NOTE: If you are making a 'bundle' of your application with a tool
like py2exe then you should *not* use the wxversion module since it
looks at the filesystem for the directories on sys.path, it will fail
in a bundled environment. Instead you should simply ensure that the
version of wxPython that you want is found by default on the sys.path
when making the bundled version by setting PYTHONPATH. Then that
version will be included in your bundle and your app will work as
expected. Py2exe and the others usually have a way to tell at runtime
if they are running from a bundle or running raw, so you can check
that and only use wxversion if needed. For example, for py2exe::
if not hasattr(sys, 'frozen'):
import wxversion
wxversion.select('2.5')
import wx
More documentation on wxversion and multi-version installs can be
found at: http://wiki.wxpython.org/index.cgi/MultiVersionInstalls";
The applicable section from that link is at
http://wiki.wxpython.org/index.cgi/MultiVersionInstalls#head-39f9ba136f6882f69af127cb8ebf5551ddf9a208
Maybe there's another way to handle the hook to implement their
suggestions? I'm getting a bit out of my depth here :)
