This is a sketch of what I want to do. This seems to work seamlessly
with the
included indexing suite. I cannot figure out how the make it work with
the advanced one.
---------------------- c++
----------------------------------------------
struct foo
{
int bar;
};
class_<foo>("foo")
.def_readwrite("bar", &foo::bar)
;
#if 1
//this does not work the way I want
class_< std::vector<foo> >("class_< std::vector<foo> >("VectorOfFoo") )
.def( indexing::container_suite< std::vector<foo> >() )
;
#else
//I think this should work the way I want, but it will not compile.
class_< std::vector<foo> >("VectorOfFoo")
.def( indexing::container_proxy< std::vector<foo> >() )
;
#endif
----------------------Python--------------------------------------------
--
v = VectorOfFoo()
f = foo()
f.bar = 0
v.append(f)
assert v[0].bar == 0
v[0].bar = 10 #This returns the foo by value. That does not happen with
the bp::vector_indexing_suite.
assert v[0].bar == 10 # this fails. v[0].bar is still 0

Unfortunately, I never used this class before. If you will send
**small and complete** example of what you are trying to do, I will
take a look on it.
