This is cool! It works with mayavi, which is a pretty demanding test. I did run into problems with pyximport messing up on some imports but manually importing the inputhook.so fixed those. The interactive response is not snappy but it definitely works without a problem. One problem I can see with this is that while it does eliminate the threading, there are still issues with multiple toolkits. It would be neat if there were a system where you could mix toolkits too -- it looks like it should be possible to support this though. cheers, prabhu ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ Matplotlib-devel mailing list Matplotlib-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-devel
