Re: [pygame] Help with C API

[Riccardo Trocca <rtrocca@libero.it>]

Hello again! 
I've found a partial answer to my problem! 
I was using C++ files. I mean that I asked SWIG to generate C++ files,  in
this way I could use default parameters in the function definition  (that
was inlined). 
Switching to C  file generation (and losing default parameters, sigh

  ) I was able to succesfully compile everything. 
Anyway I don't think it is a good thing, what if I want to write some  extension
using C++? 
It seems to me that it will not be possible to use PyGame in that case?  Or
is there some workaround? 
(BTW, I'm using VC++ SP5). Maybe I'm just missing something obvious,  after
all I'm not a C/C++ guru... 

Another question: 
   I've read some time ago, that it would be possible to embed a  pyGame/SDL
window in wxPython. 
Well. I tried it but without success. Is there somebody that has got  some
working demo? 

Thanks, 
   Riccardo 


P.S. 
PyGame is really a fantastic library that I'm really enjoying. Hope that
 I'll be soon able to show something.
