Re: Bringing LilyPad into LilyPond

[Ed Baskerville]

Specifically, QTKit and PDFKit (inside Quartz)--they're separate from  
the standard AppKit/Foundation frameworks. On second glance, it looks  
like the wrappers are very easy to generate, especially since I don't  
think there are any ObjC protocols to wrap.

The fact that I use QTKit and PDFKit brings up another issue--these  
are only available in Tiger and later, and I doubt you'd want to  
restrict Panther users from using LilyPond.app. At one point, I had  
LilyPad working so that those two frameworks were weak-linked, and  
the app used older classes (NSMovieView, NSImageView, etc.) when  
launched on a Panther system--the big drawback was that point-and- 
click didn't work, because NSImageView doesn't know anything about  
PDF links. Somewhere along the line I broke this and will try to get  
it fixed soon, certainly before trying to put anything into  
LilyPond.app.
