Global export not available in main.rs

[FoundationKen]

I am following the docs here to create a global callback function :

https://slint.dev/releases/1.2.0/docs/slint/src/recipes/recipes#global-callbacks

I have a slint file with the following declaration:

export global Utils {
    pure callback color-to-hex(color) -> string;
}

My main looks like this:

slint::include_modules!();

fn main() {
    let app = App::new().unwrap();

    app.global::<Utils>().on_color_to_hex(|color| {
        "#ff00ff"
    });

    app.run().unwrap();
}

I was able to reference the Utils.color-to-hex() function in one of my other slint files, and it does not give an error in VSCode while editing, but I get the following compiler error on the Rust side:

error[E0412]: cannot find type `Utils` in this scope
  --> src/main.rs:20:18
   |
20 |     app.global::<Utils>().on_color_to_hex(|color| {
   |                  ^^^^^ not found in this scope

I was expecting that the slint::include_modules!(); would bring the globals into scope the way it does for App, which is in my local slint!() macro, but that does not seem to be happening.

Is there some step I am missing to make Utils available in the Rust code?

you should do re-import and export { Utils } from the main slint file (or slint! macro)

Thanks! That is the fix.
