Struct OpenDialog 

pub struct OpenDialog { /* private fields */ }

The system’s dialog for choosing a file to open.

It blocks until answered and has to run on the UI thread, which is where event handlers such as on_click run.

use ravenrs_platform_native::OpenDialog;

let chosen = OpenDialog::new().title("Abrir").filter("Texto", &["txt"]).ask();
if let Some(path) = chosen {
    let text = std::fs::read_to_string(path)?;
}
