http://www.velocityreviews.com/forums/t291623-why-overload-operator-as-friend-.html So the friend keyword is needed in C++. And there or two ways to write/reach the same thing with operator==. Operators with 2 args, need the friend word to reach the private members. In principle it is a function which is not part of the class, but declared inside it. In any case if you generate the next (after the word WRONG), all is fine. %class %noclassinfo %encapsulate a2dAffineMatrix %operator bool operator== ( const a2dAffineMatrix& a, const a2dAffineMatrix& b ) Should become: static int LUACALL wxLua_a2dAffineMatrix_op_eq(lua_State *L) { // const a2dAffineMatrix b const a2dAffineMatrix * b = (const a2dAffineMatrix *)wxluaT_getuserdatatype(L, 3, wxluatype_a2dAffineMatrix); // const a2dAffineMatrix a const a2dAffineMatrix * a = (const a2dAffineMatrix *)wxluaT_getuserdatatype(L, 2, wxluatype_a2dAffineMatrix); // get this a2dAffineMatrix * self = (a2dAffineMatrix *)wxluaT_getuserdatatype(L, 1, wxluatype_a2dAffineMatrix); // call op_eq // WRONG bool returns = ((*self)(*a, *b)); bool returns = *a == *b; // push the result flag lua_pushboolean(L, returns); return 1; } ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ wxlua-users mailing list wxlua-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wxlua-users
