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 ipython, but don’t use the -pylab or -wthread flag. At this point, I need help testing the heck out of this (window and linux users esp). I have run most matplotlib pylab_examples and they work fine. I also need people to try out things like ETS/Mayavi. The current plan is to replace the existing threaded shells in IPython with this (much simpler) code.
Cheers,
Brian

I won't be able to do that reliably before two weeks, I am travelling and
have deadlines on top of that. Maybe somebody else can try this?
Cheers,

Works for me with wx 2.8.8.1 on OS X 10.5 and Chaco. Pan and zoom
interactions are substantially chunky, though. I do not see such
chunkiness with -wthread. It would be worth exploring a Cython
alternative to see if it is just ctypes and general Python overhead to
blame.

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.
Cheers,
Brian

Pan is perfectly smooth, zoom is a bit chunky, but not much, it's
definitely usable.

I also tested mayavi, this demo:
http://code.enthought.com/projects/mayavi/docs/development/html/mayavi/mlab.html#a-demo
and I didn't notice any speed difference --- e.g. it's as slow as
regular mayavi with ipython -wthread.

Nice, nice!
Test the volume_slicer example, with latest release, please. That should
be a good test.

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 version (with approach 3) to see if it is satisfactory in terms of performance AND idle CPU load. On my system MacBook Pro, the idle load is now below 1%.
Cheers and thanks,
Brian
