Dynamic text

[tyilo]

I have a use-case where I need to update the title/description for a Select in another thread. Currently I can't use demand at all for this part.

Maybe this is out of scope for demand, but it would be nice if it was possible to do something like:

let price = 100;

let handle = Select::new(format!("Coins inserted: 0, price: {price}"))
  .option(DemandOption::new("Complete payment"))
  .option(DemandOption::new("Quit"))
  .run_in_thread();

{
  let handle = handle.clone();
  std::thread::spawn(move || {
    loop {
      // fetch coins inserted
      let balance = ...;

      handle.set_title(format!("Coins inserted: {balance}, price: {price}"));

      sleep(Duration::from_secs(1));
    }
  });
}

let result = handle.wait();

If you want to support this it might also make sense to make the options dynamic, but I think that would be harder to do.
