wx.lib.pubsub in wxPython 2.8.11.0 and py2exe

Werner · August 6, 2010, 9:30am

I recall some issue on this but can't find but the final solution is for this.

I had in my module mypublisher.py:

from wx.lib.pubsub import Publisher
# variables instead of strings for topics
statusText = 1 # pass status text in data section
dataNeedsSaving = 2 # pass parent's name in data section to limit propagation, e.g. self.parent.Name
etc etc

def SetDefaults():
global publisher
publisher = Publisher()

SetDefaults()

I change it to:

import wx.lib.pubsub.setupv1
from wx.lib.pubsub import pub

#variable stuff

def SetDefaults():
global publisher
## publisher = Publisher()
publisher = pub.Publisher()

SetDefaults()

This works when I run it in e.g. Boa, but after I generate it with py2exe I get the following exception:
**** Fri Aug 06 11:25:28 2010 **** Version: 3.1.747.9 **** wxV: 2.8.11.0 (msw-unicode) *****

Can someone please point me to the doc/resolution on how I need to change mypublisher.py to keep using version 1 of pubsub.

Thanks

Try changing this to setuparg1 instead of setupv1

This gives me some other errors.

Went pack through the archive again and found the one I overlooked before.

Needed to add an empty __init__.py to the folder wx.lib.pubsub.pubsub1.

To sum it again for the archive.

Previous to wxPython 2.8.11.0 I had:

from wx.lib.pubsub import Publisher
publisher = pub.Publisher()

Changes needed to work with new pubsub as of 2.8.11.0:

import wx.lib.pubsub.setupv1
from wx.lib.pubsub import pub
publisher = pub.Publisher()

Add an empty __init__.py to the folder wx.lib.pubsub.pubsub1

And add 'wx.lib.pubsub' to "packages" within your setup.py.

Correction, above was:

I have had a number of problems in the past with missing empty files - I suspect that some zip/unzip tools skip empty files on the basis that if there is nothing in them they "don't matter" - Can I suggest that it would be good practice NEVER to have empty files rather have a file that just contains a, (file type compliant), comment telling others what it is there for, this will make it clearer and since the file will not be empty, i.e. zero bytes, it should avoid any tidying up by well meaning tools. For those of us that write tools that check for empty files we should make an effort to ensure that we equate isempty and ismissing and treat them the same...

Just my 2p worth

Agree that is a good practice, mine actually has "# to make py2exe find it" in it, the point of the file is to "declare" pubsub1 as a package below the package pubsub and therefore the following line will ensure that py2exe will include it in the dist.

Sorry I was away on vacation. Glad you figured it out. Also, have you tried

import wx.lib.pubsub.setuparg1

from wx.lib.pubsub import pub

publisher = pub

Oliver,

Sorry I was away on vacation.

Nothing to be sorry about, I hope

Glad you figured it out. Also, have you tried

import wx.lib.pubsub.setuparg1
from wx.lib.pubsub import pub
publisher = pub

I think I did. Will leave it alone for the moment as it works, plan to move to the new api at some point in the near future anyhow.
