[Swig-user] import/include - multiple wrappers question

[Boris M. <bor...@la...>]

Hi,

I am trying to do some kind of plugin system in TCL, with SWIG, from C++ 
objects.
I am new to SWIG so I am wondering if I use import/include directives 
correctly.

Suppose I have a main module in which I have a base class A (with 
virtual methodes and non-virtual methodes) and a function that takes a A 
pointer.
For example, A.hpp is :
--------------------------------
class A
{
public:
  A();
 virtual void f1();
 void f2();
};

extern void f(A *a);  // f will call a->f1() & a->f2()
--------------------------------

and A.i is
--------------------------------
%module AM
%{
#include "A.hpp"
%}
%include "A.hpp"
--------------------------------

 From these files (and A.cpp not shown here) I get a AM.so
I also have a class B redefining the virtual methods (B kind of classes 
will be my plugins).
For example :
--------------------------------
class B
{
  B();
  virtual void f1();
}
--------------------------------

 From which I get a BM.so  and I want to use these two modules in a 
script. For exemple, test.tcl is
--------------------------------
#!/usr/bin/tclsh

#load modules
load AM.so
load BM.so

#define a B object
B my_b 

#call f() with B object as parameter
f my_b
--------------------------------

How do I write B.i to have the correct behavior ?

If I write B.i
--------------------------------
%module BW
%{
#include "B.hpp"
%}
%import "A.hpp"       // "import" here !!!
%include "B.hpp"
--------------------------------
when I call "f my_b" in the script, it is known that B inherits from A 
(so f1() from B is called),
 but f2 is not wrapped for B !

If I write B.i as
--------------------------------
%module BW
%{
#include "B.hpp"
%}
%include "A.hpp"       // "include" here !!!
%include "B.hpp"
--------------------------------
it works correctly but the A's wrapping is both in AM.so & BM.so, isn't 
it ?
So A's wrapping will be in each of my plugins !
Is it the right way to achieve what I want ?


Thank you,

Boris.
