        .add_filter("JPEG Image", &["jpg", "jpeg"])
        .show_open_single_file()
        .unwrap();

    let path = match path {
        Some(path) => path,
        None => return,
    };

    let yes = MessageDialog::new()
        .set_type(MessageType::Info)

        .set_text(&format!("{:#?}", path))

        do_something(path);
    }

Misc

Why the dialogs look ugly/blurry on Windows?

Turn on crate features or embed manifests into the .exe to enable visual styling and dpi awareness for your program. Check out examples/windows_manifest and examples/windows_features for example.

Why the program crashed when opening a dialog on macOS?

The UI framework of macOS (Cocoa) has a limitation that all UI operations must be performed on the main thread.
