It might be lack of sleep, but I can’t figure this out.

I have a Label, and I want its text to be red when it represents an error, and I want it be green when it represent “good to go”.

I found search result for C and maybe a solution for Python, but nothing for Rust.

I tried manually setting the css-classes property and running queue_draw(); it didn’t work.

I can have a gtk::Box or a Frame that I place where the Label should go, then declare two Labels, and use set_child() to switch between them, but that seems like an ugly solution.

Do you have a solution?

    Before anyone suggests another library:

    • Iced and Egui both can’t handle Arabic, which is a deal breaker.
    • Iced takes forever to compile and iterate, maybe that’ll be fixed with dynamic linking.
    • Relm: I didn’t know it existed before I started this project.
    • Qt bindings: IDK I forgot Qt existed, I was always more of GNOME* guy.
    • I am already pretty deep into this project, and don’t want to learn something else for now.

      Use libcosmic 😑

      No, but seriously… skip to the end.

      Iced and Egui both can’t handle Arabic, which is a deal breaker.

      Iced can handle Arabic shaping-wise when cosmic-text is used, but it can’t handle the direction (yet). If you only need it for the interface, a shit workaround would be to prefix all text with an RLM (RIGHT-TO-LEFT Mark). This would left-align all text of course.

      Iced takes forever to compile and iterate, maybe that’ll be fixed with dynamic linking.

      Fast iteration is already fixed by using cranelift in your release-dev profile (or whatever you want to call it), and mold as a linker. The binary will be slower, but iteration will be much much faster.

      Okay, something helpful instead: Did you try asking in the rust:gnome.org matrix room mentioned in the project page?
