Re: Implicit conversion : const char * -> QString

> Does luabind provide such implicit conversion ?

Yes, but with a little help. You should overload luabind::default_converter for that. For example, this is mine that I wrote to support std::wstring conversion. Just ignore that 'Widen' and 'Narrow' thing, it's just my handling of wide-string conversion to 8-bit lua strings. I think adding the support for QString will be similar.

namespace luabind
{
      template <>
	struct default_converter< std::wstring >
		: native_converter_base< std::wstring >
	{
		static int compute_score( lua_State * s, int index )
		{
			return lua_type( s, index ) == LUA_TSTRING ? 0 : -1;
		}

		std::wstring from( lua_State * s, int index )
		{
			return StrUtils::Widen( lua_tostring( s, index ) );
		}

		void to( lua_State * s, const std::wstring & str )
		{
			lua_pushstring( s, StrUtils::Narrow( str ).c_str( ) );
		}
	};
	/**/

	template <>
	struct default_converter< const std::wstring >
		: default_converter< std::wstring >
		{ };

	template <>
	struct default_converter< const std::wstring & >
		: default_converter< std::wstring >
		{ };
}
