log messages to text widget?

[unrushed-boots]

with a text widget in a scrollable is there an example for printing log messages? either log or tracing is fine. seems like using in-out variable and newlines is ok, but cant pass the widget to the trait to write to. all my testing/demo code prints to stdout not the gui. there also seems an async issue with tracing when trying. not sure what to do from here with it. any help or possibly new example in repo?

you will need to do something like this: (i have not tested to run this code, just wrote it on the spot)

let message = ... the message to log ...;
slint::invoke_from_event_loop(move || {
   LOG_WINDOW.with(|log_window| { // the log_window is stored in a thread_local
        log_window.invoke_add_log(message); // invoke a function `add-log` declared in your .slint file
   });
});
