I see, so if i understand well, each call to

genwxbind.lua

should be one a set of *.i files which are selfcontained. Meaning all class names should be somewhere in there.
What if one uses classes from an other  module/library, e.g derived classes. The base class is wrapped already (with a seperate call to genwxbind.lua) , the baseclass of the derived class in the new module needs to be know too. 
So in that case one needs the empty class defenition as a sort of forward declaration right?

What i conclude from this is that we need soem sort of *.ih files for module, being a header of know types from another module. Something like filling the list of know types.

Maybe we should have a %forward class classname, to achieve the next from the rules file, but from a *.i file.

dataTypes["wxCursor"] = AllocDataType("wxCursor", "class", false)

Did would make it a bit more moduler.
