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?
SOLVED:
I have to add a “.” before declaring a CSS “thing” for it to be considered a class.
Ex:
.overlay {
background: rgba(60, 60, 60, 1);
font-size: 25px;
}
instead of:
overlay {
background: rgba(60, 60, 60, 1);
font-size: 25px;)
}
Just use label.add_css_class(), label.remove_css_class() or label.set_css_classes() and make sure to properly load your CSS style sheets,

This is embarrassing, but when was it not?
I have to add a “.” before the name of a
cssclass, I must learn my tools.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.
(sorry for the late response, I have to get in the habit of checking my Lemmy account)
No, I get that - a stylesheet denotes a class by having a dot. A JavaScript API for adding a CSS class omits this redundancy.
I was saying that the author might not be wrong to want to avoid the redundancy in rust example as well (since it explicitly mentions CSS classes).
