[Insight-users] extend classes with cableswig

[Gaetan Lehmann]

Hi Brad,

swig allow to extend classes with the keyword %extend.

I want to implement methods such as __getitem__, __setitem__ and __len__  
in Size, Index, Array and FixedArray classes, so those basic objects can  
be accessed with native python interface, and with bound checking, which  
is more python user friendly. Adding __repr__ or __str__ method to those  
classes would also allow user to easily see the content of objects of  
those classes...
Also, I want to implement __str__ in LighObject class, to return the  
string produced by the Print method, so lots of itk objects can be printed  
with "print anItkObject"

Sadely, with cableswig, it seems %extend have no effect. Do you know why ?
What can be done to extend classes ? Currently, I'm adding all those  
method directly in .h files...

Thanks

Gaetan
