[Lua-icxx-users] lua_icxx + swig

[Domenico M. <dm...@gm...>]

Hi,

I'm playing around with lua_icxx. I find it very useful with its unique
approach to lua calls within c++.

I'm currently using swig to wrap a large library and I'm using lua_icxx to
provide callback supports from within c++ into lua.

Here is an example

*c++ *

// Note : Foo is wrapped by swig

class Foo
{
  public:

    LuaFuncRef cb;

    void registerCallback(const char* cb)
    {
        cb = _lua.eval(cb);
    }
    .....

    void execCallback()
    {
       cb();
    }
};





*lua :*


function test()
    print("cool")
end

f = Foo()
f:registerCallback("test");




That's all good.

My problem now is to make use of swig wrap to pass c++ objects to lua
callback;

Something like this

    void execCallback()
    {
       cb( new Foo );
    }

The callback works fine with basic types but not for UDT.

Any idead how that could be solved ?


Thank you for sharing this lib.
