Nice! I briefly looked at the code and from what I can see you
transparently wrap the builtin functions used inside all the wxPython
functions. This means apply is wrapped and therefore everything works
I've managed to work around the kiva_agg build problem by building the
offending code with gcc-3.0. How does one specify to python setup.py
to choose gcc-3.0 instead of vanilla gcc? Setting the environment
variable CC does not appear to help.
Anyway, the new gui_thread works really nicely. I like the fact that
you don't have to wait before you run the next statement since you
wait while importing wxPython. However, the new gui_thread appears to
have trouble when quitting the interpreter:
In : from gui_thread import wxPython_thread; wxPython_thread()
In : from chaco.wxplt import *
In : p=plot([1,2])
In : close()
Do you really want to exit ([y]/n)?
