cargo run --example window

Usage

Glutin is an OpenGL context creation library and doesn't directly provide OpenGL bindings for you.

[dependencies]
gl = "*"
libc = "*"
extern crate gl;
extern crate glutin;
extern crate libc;

fn main() {
    let window = glutin::Window::new().unwrap();

    unsafe { window.make_current() };

    let gl_ = match api_type {
        gl::GlType::Gl => unsafe { gl::GlFns::load_with(|s| Self::get_proc_address(s) as *const _) },
        gl::GlType::Gles => unsafe { gl::GlesFns::load_with(|s| Self::get_proc_address(s) as *const _) },
    };

    gl_.clear_color(0.0, 1.0, 0.0, 1.0);

    for event in window.wait_events() {
        gl_.clear(gl::COLOR_BUFFER_BIT);
        window.swap_buffers();

        match event {
            glutin::Event::Closed => break,
            _ => ()
        }
    }
}

Note that glutin aims at being a low-level brick in your rendering infrastructure. You are encouraged to write another layer of abstraction between glutin and your application.

Platform-specific notes

Android

  • To compile the examples for android, initialize the submodules, go to deps/apk-builder/apk-builder and run cargo build, then go back to glutin and call ANDROID_HOME=/path/to/sdk NDK_HOME=/path/to/ndk NDK_STANDALONE=/path/to/standalone cargo test --no-run --target=arm-linux-androideabi
