    the hidden “trashbin”, .Trash-$(uid), invented by Ubuntu

    This isn’t some “idiotic principle invented by Ubuntu”, it just follows the freedesktop.org Trash specification. For many users, it can be really beneficial, see also the spec’s introduction:

    An ability to recover accidentally deleted files has become the de facto standard for today’s desktop user experience.

    Users do not expect that anything they delete is permanently gone. Instead, they are used to a “Trash can” metaphor. A deleted document ends up in a “Trash can”, and stays there at least for some time — until the can is manually or automatically cleaned.

    Whether an application like Prism Launcher should use the trash can or delete the files directly is an entirely different question.

    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 usually done by including them as a resource alongside .ui files and icons. If you are using libadwaita, you can also use its predefined style classes.

    full example (requires nightly toolchain) 
    #!/usr/bin/env -S cargo +nightly -Zscript

[dependencies]
gtk = { package = "gtk4", version = "0.9.3", features = ["v4_12"] }

use gtk::{glib, prelude::*};

const STYLESHEET: &str = r#"
.green {
    color: green;
}
.red {
    color: red;
}
"#;

fn main() -> glib::ExitCode {
    let app = gtk::Application::builder()
        .application_id("org.example.HelloWorld")
        .build();

    app.connect_activate(|app| {
        let window = gtk::ApplicationWindow::builder()
            .application(app)
            .title("Hello, World!")
            .build();

        // Stylesheets are usually bundled with application resources
        // and automatically loaded
        let css_provider = gtk::CssProvider::new();
        css_provider.load_from_string(STYLESHEET);
        gtk::style_context_add_provider_for_display(
            &RootExt::display(&window),
            &css_provider,
            0
        );

        let box_ = gtk::Box::new(gtk::Orientation::Vertical, 6);

        let label = gtk::Label::builder()
            .label("Hello, World")
            .css_classes(["green"].as_slice())
            .build();
        box_.append(&label);


        let button = gtk::Button::builder()
            .label("Toggle Color")
            .build();
        box_.append(&button);

        button.connect_clicked(glib::clone!(#[weak] label, move |_| {
            if label.has_css_class("red") {
                label.add_css_class("green");
                label.remove_css_class("red");
            } else {
                label.add_css_class("red");
                label.remove_css_class("green");
            }
        }));

        window.set_child(Some(&box_));
        window.present();
    });

    app.run()
}
