Re: How can I install Window types in lua ?

"Trying to use unregistered class' means the class you are registering
either takes an unregistered parameter or returns one which you need
to register.
Windows mainly use void* you need to cast. I am not sure how luabind
reacts to that. You could try to cast explicitly functions on
registration.
