Any way to await slint actions?

[gcb]

I think this will get a negative answer, like in #5840, but if I don't care about knowing the result, just that the event was acted on, can I somehow wait on invoke_from_event_loop or other? or all the Result<(),... are to make it clear this will not be possible on any of those?

Or will I need to have an event counter and a done callback of sorts?

Would be indeed nice if invoke_from_event_loop could return a future or a handle like slint::spawn_local does. But this was implemented before and doesn't have this ability.

So this can be implemented manually (assuming you are in a thread, if not, use spawn_local)

let (tx, rx) = std::sync::mpsc::channel();
invoke_from_event_loop(move || {
   // ... do stuff
   tx.send(value).unwrap()
).unwrap();
let value = rx.recv().unwrap()

Use a similar pattern with async channel from a crate if you want to use it with async rust.

thanks. that is simpler than using a callback as i was planning.
