I can't make cableswig use swig commands. Perhaps can you help me ?


My itk.swg file (using itk 2.0.1) :

/* This is an itk-specific typemap used by CableSwig.  Also see comments
  * and "throws" code in CableSwig.cxx.
  *   -- Charl P. Botha <cpbotha AT ieee.org>
  */

#ifdef SWIGPYTHON

/* ------------------------------------------------------------
  * PyObject *  - Just pass straight through unmodified
  * This is default behaviour for python.swg, but Cable passes
  * a PyObject * through as a "p._object", so we redo the typemap
  * ------------------------------------------------------------ */

%typemap(in)   p._object "$1 = $input;";
%typemap(out)  p._object "$result = $1;";
%rename(__getitem__) itkIndex2::GetElement;
#endif

%include exception.i

/* A "throws" attribute with the "std::exception" type is added  
synthetically
  * to each method node by CableSwig.cxx.  When gcc_xml starts passing  
through
  * correct throws types, this typemap could be optionally extended to
  * account for more different types.  For now this is sufficient though.
  */

%typemap(throws) std::exception {
    SWIG_exception(SWIG_RuntimeError, const_cast<char*>(_e.what()));
}

%include std_string.i




I think that with this line :

%rename(__getitem__) itkIndex2::GetElement;

objects of itkIndex2 class should have a __getitem__ method and no  
GetElement method. But it don't work, and I can't understand why.
