IPython and matplotlib devs,
Over the weekend I have been playing around to see if it is possible
to do interactive GUI work with wx from IPython *without using
threads*. The idea here is to use PyOS_InputHook. Currently, recent
versions of PyQt4 and PyGTK do this and if we can get wx working, w

Yes, that would be nice!!!

Hello all,
[sent to mpl-dev, enthought-dev and ipython-dev]
This summer, we are doing some major refactoring of IPython's core. One of
the things I am working on is changing how IPython's works with GUI
toolkits. These changes will have a significant impact (hopefully for the
better) on your pr

After playing a bit more, I have a ctypes based prototype that can set
PyOS_InputHook in an appropriate way for wx 2.9 (trunk). I think it is
possible to have a ctypes based version that would work for all the major
GUI toolkits that we could ship with IPython until the transition is over

Yes, 2.8 is latest stable, so we should support it. How many people would
complain if 2.6 were not supported? I take it
Hi,
I am attaching a working ctypes based prototype of a module that allows wx
to be used interactively from *both* python and ipython. It uses
PyOS_InputHook and has been tested on wx 2.8 and 2.9 (trunk) on Mac OS X
(python 2.5).
It can be used with an existing wx install and all versions of ip
Robert,
Thanks for testing this so quickly. Performance is one of the big issues
that I am concerned about. I will work on a Cython based version to see if
that solves the problem.

All,
I have an improved prototype of my ctypes based inputhook for wx. In this
version I have:
* Added and tested Ondrej's patch. It seems to improve both responsiveness
and idle GPU load. Thanks Ondrej!
* Tested on Win32
* Small changes related to the GIL.
Robert and Gael, can you test this

Hello all,
While at SciPy this year, the IPython devs began discussing dropping Python
2.4 support. Or rational is this:

our Twisted using components.
* Being able to use absolute imports would simplify the packaging of

Hi,
We are in the process of getting our new Qt IPython GUI working with

situations where another part of an application has already created a

Hello all,
I would like to submit the following branch on github for review and

It is not clear to me that the stream of PNGs will win in the end. If

I wonder if it would be beneficial to give up a little on the quantitative
