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?

    I mean, it is not embarrassing for you. In the browser, the CSS’s “native platform”, you add classes, via the JavaScript API, without the dot. It’s not a stupid assumption.

    To have to add the dot in the CSS class name seems a bit of an oversight in the gtkrs API.

      I think you understood their comment wrong. In your code (e.g. label.add_css_class("green");) you don’t use a dot, but in the CSS stylesheet. It works the same as with HTML/JS/CSS.
