Re: [wxPython-users] Re: wxPython 2.8.11.0 Pubsub not found by py2exe

[oliver]

So the py2exe freezing problem occurs only when using the legacy API. Two problems: 

1. the "imp" module from Python core library does not seem to work within zip files, so autosetuppubsubv1 is not found, eventhough it is in the .zip created by py2exe. Solution (hack): import setupv1 explicitly in your application's startup module. 
2. legacy API setup requires the wx/lib/pubsub/pubsub1 folder, which for a reason that I don't yet understand, py2exe does not copy into the library.zip. Solution (another hack): put an empty __init__.py in that folder. 

The much preferable alternative (ie no hacks!) if you can hack it (sorry!) is to use the same messaging protocol as v1 but in latest API, this is called "arg1": 

from wx.lib.pubsub import setuparg1             # only in app's startup module

from wx.lib.pubsub import pub as Publisher # in all modules that use pubsub

and replace any occurence of "Publisher()." by "Publisher."

So I'm using the new API and didn't even know it? I'm pretty sure I
was basing my code on old examples, and I think I've been using this
code since at least wx 2.8.9.x so I don't know how this works...

I've tried it with

from wx.lib.pubsub import setupv2

from wx.lib.pubsub import Publisher

The above doesn't work at all from source (probably for some obvious
reason). The following doesn't work when frozen:

from wx.lib.pubsub import Publisher

or

from wx.lib.pubsub import setupv1

from wx.lib.pubsub import Publisher

The solution is simple! Downgrade to 2.8.10.1. I guess I need to
figure out whatever the new accepted way is and just do it that way...
