I always see new GTK apps popup on Flathub. I dont really care and think GTK looks fancy, although CSD suck a bit and they waste space and often functionality.
But they work, are solid, and do what they should.
Qt on the other hand may seem more like a complex job to code with. I dont actually think so, but I heard especially writing rust with GTK is way better than with Qt.
I like KDE a lot, and even though I am excited for Cosmic I think Qt is the better toolkit for many things and a lot of time. But Dolphin seems to suffer from memory safety issues all the time, as well as other projects.
Do you have experience in rust, using GTK or Qt? How do they compare?
C bindings and APIs generally work much better in Rust because the language works a lot more like C than it does C++.
Qt depends a lot on C++ class inheritance, and even does some preprocessing of C++ files to generate code in those classes. That’s obviously not possible when using Rust. And it looks like you need a fair bit of unsafe there and there to use it at all too.
Meanwhile, GTK being a C library, its integration with Rust is much more transparent and nice.
So if you’re making a GUI Rust app, you’re just kind of better off with GTK at the moment. It’s significantly easier and nicer.
