Re: [Rubycocoa-talk] ATSUI API

[Eloy D. <elo...@gm...>]

Hi Duncan,

Take a look at the gen_bridge_metadata tool. ($ man gen_bridge_metadata)

If I recall it correctly it would be something like:
$ gen_bridge_metadata -f /System/Library/Frameworks/ 
ApplicationServices.framework/Versions/Current/Frameworks/QD.framework  
 > QD.bridgesupport

You can then load that file with OSX.load_bridge_support_file

Cheers,
Eloy
