fltk图形框架使用教程

环境

• 安装rust
• 安装msvc
• 安装cmake
• 安装 Git

设计工具

cargo install fltk-fluid fl2rust

• 在项目中添加
  build.rs

use std::path::PathBuf;
use std::env;

fn main() {
    println!("cargo:rerun-if-changed=src/myui.fl");
    let g = fl2rust::Generator::default();
    let out_path = PathBuf::from(env::var("OUT_DIR").unwrap());
    g.in_out("src/myui.fl", out_path.join("myui.rs").to_str().unwrap()).expect("Failed to generate rust from fl file!");
}

myui.rs

#![allow(unused_variables)]
#![allow(unused_mut)]
#![allow(unused_imports)]
#![allow(dead_code)]
#![allow(clippy::needless_update)]

include!(concat!(env!("OUT_DIR"), "/myui.rs"));

main.rs

use fltk::{prelude::*, *};
mod myui;

fn main() {
    let app = app::App::default();
    let mut ui = myui::UserInterface::make_window();
    ui.but.set_callback(move |_| {
        println!("Works!");
    });
    app.run().unwrap();
}

Cargo.toml

• 添加打包压缩二进制配置

[profile.release]
opt-level = 'z'     # 根据尺寸进行优化
lto = true          # 启用链接时间优化
codegen-units = 1   # 减少代码生成单元的数量以增加优化.
panic = 'abort'     # Abort on panic
strip = true        # 从二进制中删除符号

• 添加框架包

[dependencies]
fltk = "1.4.13"

[build-dependencies]
fl2rust = "0.5.17"
