you have to write the method with the following prototype:
 void SetCallback (lua_Object f);

(tolua understands lua_Object as a valid and known type)

to store the object in C++, you can use lua_ref (or the lua registry table).
the lua function is then called using the convetional Lua API.

Hi!

Consider the following cleaned class, in sample.pkg:



class Sample{
  Sample();
  ~Sample();

  void SetCallback( t_function f );// what type is correct to get a
Lua function pointer?
}

In Lua, I would like to do this:

function test()
...
end


sample = Sample:new()

sample:SetCallback(test)

That's the point! In C++, what type is "t_function"?
And how to store the address of the parameter (a function) in C++, to
call it later?

I know how to do all this in pure Lua, but using tolua (a great tool)
I don't know how!!!
