another change note

[wxWidgets.git] / wxPython / src / my_fragments.i

// These fragments are inserted in modules that need to convert PyObjects to
// integer values, my versions allow any numeric type to be used, as long as
// it can be converted to a PyInt.  (Specifically, I allow floats where the
// default SWIG_AsVal_long would just raise an exception.
//
// NOTE: This file has to be %included very early in the SWIGging process as
// it no longer allows existing fragments to be replaced with one of the same
// name.  So to make this work I had to bring a copy of python.swg into this
// project and do the %include there before most other of the standard swiglib
// files are %included.  This may change in 1.3.23, so adjust accordingly then.
