我试图创建一个使用活塞板条箱打开全屏窗口的应用程序。

如何以编程方式检索以像素为单位的物理屏幕尺寸？这似乎是一件容易的事，但我无法弄清楚。

extern crate piston;
extern crate glutin_window;
extern crate graphics;
extern crate opengl_graphics;

use piston::window::WindowSettings;
use piston::event_loop::{Events, EventLoop, EventSettings};
use piston::input::RenderEvent;
use glutin_window::GlutinWindow;
use opengl_graphics::{OpenGL, GlGraphics};

fn main() {
     let opengl = OpenGL::V3_2;
    // Is there any way to retrieve the screen size programmatically and not to hard code it?
    let (screen_width, screen_height) = (1920, 1080);
    let settings = WindowSettings::new("The Game Of Life", [screen_width, screen_height])
        .graphics_api(opengl)
        .fullscreen(true)
        .exit_on_esc(true);

    let mut window: GlutinWindow = settings.build()
        .expect("Could not create window");

    let mut events = Events::new(EventSettings::new().lazy(true));
    let mut gl = GlGraphics::new(opengl);

    while let Some(e) = events.next(&mut window) {
        if let Some(args) = e.render_args() {
            gl.draw(args.viewport(), |c, g| {
                use graphics::{clear};

                clear([1.0; 4], g);
                //DO STUFF HERE
            });
        }
    }
}

看来你可以

    let mut window: Window = WindowSettings::new("spinning-square", [200, 200])
        .graphics_api(opengl)
        .exit_on_esc(true)
        .fullscreen(true)
        .build()
        .unwrap();

    let monitor_id = window.ctx.window().get_current_monitor();
    let size = monitor_id.get_dimensions(); // this looks platform dependent

有趣的是，我在寻找它的目的与“生命游戏”完全相同
