Re: [Rubycocoa-talk] ATSUI API

[Duncan M. <du...@on...>]

Always the way, just as soon as you post - you find the solution.

So for those who may follow

require_framework '/System/Library/Frameworks/ 
ApplicationServices.framework/Versions/Current/Frameworks/QD.framework'

is correct, but I then need to use QD::ATSUCreateStyle

Keep up the good work :-)
