安装QT5，过程省略

安装rust，过程省略

创建工程

cargo new slint_demo

在cargo.toml添加依赖

[dependencies]
slint = "1.1.1"

[build-dependencies]
slint-build = "1.1.1"

创建build.rs

fn main() {slint_build::compile("ui/main.slint").unwrap();println!("cargo:rustc-link-lib=static=Qt5Core");println!("cargo:rustc-link-search=native=D:/Qt/qt/5.15.2/msvc2019_64/lib");
}

创建UI文件main.slint

import {GroupBox, LineEdit, Button} from "std-widgets.slint";export component MainWindow inherits Window {title: "slint demo";width: 640px;height: 480px;VerticalLayout { alignment:start;padding-left: 25px;padding-right: 25px;Text { font-size: 27px;font-weight: 700;color: #6776FF;  }GroupBox{title:"用户名";LineEdit {placeholder-text: "请输入用户名";}}Button {text: "登录";clicked => { self.text = "单击"; }}}
}

创建main.rs

slint::include_modules!();fn main() {MainWindow::new().unwrap().run().unwrap();
}

目录结构

编译

cargo build

运行

cargo run

把qt的dll文件路径加入PATH环境变量

set PATH=D:\Qt\qt\5.15.2\msvc2019_64\bin;%PATH%
