Re: [Wxlua-users] tolua++ and wxLua

[John L. <jla...@gm...>]

ps. I've added a wxString stub to wxLua. All there is a constructor to
create a wxString from a lua string and the function GetData() to
return it back to a lua string.

wxString(lua string)
luastr = wxstr:GetData()

You still won't be able to convert the tolua++ wxString userdata to
wxLua's wxString unless you figure out how to do this yourself.
