Rust语言使用iced实现简单GUI页面

article 2025/3/6 21:12:40

使用cargo新建一个rust项目

cargo new gui_demo
cd gui_demo

编辑Cargo.toml文件 ,添加iced依赖

[package]
name = "gui_demo"
version = "0.1.0"
edition = "2021"

[dependencies]
iced = "0.4.2"

编辑src/main.rs文件：

use iced::{button, widget::{Button, Column, Text}, Application, Command, Element, Settings, Subscription};
use iced::executor::Default as Executor;

// 定义应用程序的状态
struct RustGuiApp {
    count: i32,
    button_state: button::State,
}

// 定义应用程序的消息类型
#[derive(Debug, Clone, Copy)]
enum Message {
    IncrementPressed,
}

impl Application for RustGuiApp {
    type Executor = Executor;
    type Message = Message;
    type Flags = ();

    fn new(_flags: ()) -> (Self, Command<Self::Message>) {
        (
            RustGuiApp {
                count: 0,
                button_state: button::State::new(),
            },
            Command::none(),
        )
    }
    
    // 设置窗口标题
    fn title(&self) -> String {
        String::from("Rust GUI Example")
    }

    fn update(&mut self, message: Self::Message) -> Command<Self::Message> {
        if let Message::IncrementPressed = message {
            self.count += 1;
        }
        Command::none()
    }

    fn view(&mut self) -> Element<Self::Message> {
        let button = Button::new(&mut self.button_state, Text::new("Increment"))
            .on_press(Message::IncrementPressed);

        //    添加文字和一些你想加的东西
        Column::new()
            .push(Text::new("Hello, Rust GUI!").size(50))
            .push(Text::new(self.count.to_string()).size(50))
            .push(button)
            .into()
    }

    fn subscription(&self) -> Subscription<Self::Message> {
        Subscription::none()
    }
}

fn main() -> iced::Result {
    RustGuiApp::run(Settings::default())
}

最后使用命令运行
