AbiWord appears to use IB (there are *.nib directories and plenty of `IBAction` and `IBOutlet` annotations), but it's kinda woven into AbiSource's own cross-platform application framework, and that actually makes it more interesting/useful as a learning resource.
Thanks for the suggestion! Any others you can think of?
Did you make any progress on this for macOS or iOS/iPadOS?
Out of total hatred of Xcode and Interface Builder I started experimenting with writing Apple UI stuff in C (calling Cocoa methods through libobjc), but there's precious few resources on doing so-called "Nibless/Xibless" development beyond the basics.
I'd love to find a decent-sized open-source macOS app written in [Objective-]C/C++ but with a good assortment of common UI paradigms, all done in code. I shudder whenever I see that dreaded .xcodeproj directory...
FYI (and in case Mr Bellard is reading), for the "Greatest Love of All" demo, the sample labeled "mono 5.02 kb/s" is in fact linked to the 6.79 kb/s stereo sample. The correct file is available at https://bellard.org/tsac/Greatest_Love_mono.wav
Thanks for the suggestion! Any others you can think of?
