Using python with wxPhoenix event loop

wxPython Users
1

Hello,

I am running Macos 10.9.5, with anaconda on python 3.4.4, ipython 4.0.3.

I installed Phoenix and latest version of matplotlib (1.5.1)

I managed ipython to call the bundled version of python by replacing in the python file

#!//anaconda/envs/py3k/bin/python3

by

#!//anaconda/envs/py3k/python.app/Contents/MacOS/python

Everything seems to go well (I can execute ‘import wx’ for instance)

However both

ipython --pylab = wx

or executing (in ipython)

%gui wx

generate the following error :

Traceback (most recent call last):

File “_ctypes/callbacks.c”, line 234, in ‘calling callback function’

File “//anaconda/envs/py3k/lib/python3.4/site-packages/IPython/lib/inputhookwx.py”, line 96, in inputhook_wx2

assert wx.Thread_IsMain()

AttributeError: ‘module’ object has no attribute ‘Thread_IsMain’

If I understand well, in Phoenix wx.Thread_IsMain() has been replaced by wx.IsMainThread(). So there seems to be a compatibility problem.

Replacing wx.Thread_IsMain() by wx.IsMainThread() in the python hooks does not seem to work.

Is there a workaround ?

Does anybody have a solution for running ipython with a wxPhoenix event loop ?

Thank you

Emmanuel

Ok, I worked on it, so now, I can run python (3.4) with pylab=wx mode (wxPhoenix) :

ipython —pylab = wx

works

But then

Could somebody help me, I really don’t know what to do now ?

Thank you
