使用Rust编写的程序，可以使用快捷键启动、最小化、最大化和关闭窗口

use gtk::{prelude::*, Application, ApplicationWindow, WindowPosition};
use gdk::enums::key;

fn main() {
    let application = Application::new(Some("com.example"), Default::default()).expect("Initialization failed...");

    application.connect_activate(|app| {
        let window = ApplicationWindow::new(app);
        window.set_title("Rust GTK Window");
        window.set_default_size(350, 70);
        window.set_position(WindowPosition::Center);
        window.set_resizable(false);

        let accel_group = gtk::AccelGroup::new();
        window.add_accel_group(&accel_group);

        let minimize_key = gtk::AccelKey::new(key::M, gdk::ModifierType::CONTROL_MASK, gtk::AccelFlags::VISIBLE);
        accel_group.connect_entry(&minimize_key, true, |_| {
            window.iconify();
        });

        let maximize_key = gtk::AccelKey::new(key::X, gdk::ModifierType::CONTROL_MASK, gtk::AccelFlags::VISIBLE);
        accel_group.connect_entry(&maximize_key, true, |_| {
            if window.is_maximized() {
                window.unmaximize();
            } else {
                window.maximize();
            }
        });

        let quit_key = gtk::AccelKey::new(key::Q, gdk::ModifierType::CONTROL_MASK, gtk::AccelFlags::VISIBLE);
        accel_group.connect_entry(&quit_key, true, |_| {
            app.quit();
        });

        window.connect_delete_event(|_, _| {
            gtk::main_quit();
            Inhibit(false)
        });

        window.show_all();
    });

    application.run(&[]);
}
