简单的 Gtk 窗口与文本

将 Gtk 依赖添加到你的 Cargo.toml：

[dependencies]
gtk = { git = "https://github.com/gtk-rs/gtk.git" }

使用以下内容创建一个简单的窗口：

extern crate gtk;

use gtk::prelude::*; // Import all the basic things
use gtk::{Window, WindowType, Label};

fn main() {
    if gtk::init().is_err() { //Initialize Gtk before doing anything with it
        panic!("Can't init GTK");
    }

    let window = Window::new(WindowType::Toplevel); 

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

    window.set_title("Stackoverflow. example");
    window.set_default_size(350, 70);
    let label = Label::new(Some("Some text"));
    window.add(&label);
    window.show_all();
    gtk::main();
}
