What to choose gtk or fltk for writing gui on rust?

Question

Rust

I want to start developing gui on rust. I settled on gtk and fltk.

Answer 1

I would look towards html/css, there are two options:
azul - fast and memory efficient, uses the same renderer as Firefox. No need to delve into js
tauri - it's easier, you can make a visual on any convenient js framework + out of the box there are tools for creating installers for all platforms and auto-updates (but you pay for this with a relatively large amount of RAM)
If you want on top of GTK - druid or vgtk - it's better than bare bindings.
There is also SixtyFPS - the description is also cool. On the desktop, he uses native controls, but there are difficulties with the license (it looks like Qt, where the open source is free, and you have to buy a commercial license)
I did not find any convenient libs for working with Qt.
In general, start from the task of how complex the UI you want to do.
