Re: Automatically generated callbacks using directors (python)

Carlos,

  Those macros look awesome. I was looking on how to deal with c++
callback and python and could not find any documentation.

Un-usable, you need to define you callback in the .i file (could
someone give me a practical example!):
http://www.swig.org/Doc1.3/SWIG.html#SWIG_nn30

Looks completely outdated:
http://www.swig.org/Doc1.1/HTML/Python.html#n11

swig comes with an example, but with a funky syntax (thisown=0 /
.disown() and you still need to explicitely delete the callback),
clearly not user oriented.
