It's such a shame this isn't a cross-platform UI toolkit. I'm not implying that I think this is the best toolkit or anything, but we can definitely use a bit of competition in that space (although kudos to Qt, they're doing an excellent job).
Not really the same, but it at least is designed with the idea of providing UI components to cross platform frameworks (React.Native,Xamarin.Forms etc.) to make them look more windows native.
Isn't it? Or is the bullet point implying they have a windows only DLL you can use in cross platform languages?
I don't think this will run on MacOS or Linux? I'd be happy to be corrected on this :)
