IupCocoa

I love the idea, and considered using this for a side project, but ultimately went a different route. The biggest issue for me was the somewhat constrained idea of "cross platform" it's working with. There was an attempt at a Cocoa port, but it seems even less active than the main project. https://github.com/ewmailing/IupCocoa Ultimately, I decided that a careful addition of a minimal amount of C++ code to use wxWidgets was less kludgey than using a half-baked Cocoa port or coaxing IUP GTK to work with Mac GTK. I've been mostly happy with that decision.

There is a project to get IUP working on OSX. https://github.com/ewmailing/IupCocoa

There is a project to add cocoa support that would appreciate some help. https://github.com/ewmailing/IupCocoa/tree/Cocoa

Eric Wing is sort of working on it. https://sourceforge.net/p/iup/mailman/message/34307825/ https://github.com/ewmailing/IupCocoa/tree/Cocoa

Honestly I kind of wonder why nobody has written a library that acts as a thin layer around and abstraction of native UI toolkits (AppKit, .NET, GTK+, etc) instead of a monolithic do-most-things-or-everything-yourself IUP is exactly this. Native GUI focused and nothing more to be thin and lightweight. It's small (under 800K). It's written in pure C so language bindings can be made for any language. It is funded by the same university that created Lua. Liberal MIT license. http://webserver2.tecgraf.puc-rio.br/iup/ Its weakness is it still lacks a native OS X backend. (People use GTK on Mac as a workaround.) There was an abandoned port attempt in 2010. Somebody just started trying to port it again a couple of weeks ago. (I'm sure additional volunteers/help are welcome.) https://www.mail-archive.com/iup-users@lists.sourceforge.net... https:
