do you have helpers for invoke methods/macros?

[gcb]

my code is getting full of

let ui2 = ui.clone();
let _ = slint::invoke_from_event_loop(move ||
    ui2.unwrap().set_some_var(false));

How do you organize your code around this?

Unfortunately, that is the verbosity of rust.

One helper is Weak::upgrade_in_event_loop

We were also experimenting with passing the handle in the callback handler: #2035

Otherwise perhaps you would get some help from one of the many crates who have one helper such as
