Re: [Wxlua-users] forward declarations

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

I have updated the genwxbind.lua and bindings/wxwidgets/wx.rules file
to use the data types cache data. I have not been able to test it with
external wrappers, but it should work. Read the comments in wx.rules.
Basicly, you have a table of the cache files, which are automatically
generated by genwxbind.lua, that you "include" in your rules file.
