git clone https://github.com/tomaka/glutin
cd glutin
cargo run --example window
```
## Usage ## Usage
Glutin is an OpenGL context creation library and doesn't directly provide OpenGL bindings for you. Winit is an OpenGL window creation and management library. It can create windows and lets you
handle events (for example: the window being resized, a key being pressed, a mouse mouvement, etc.)
produced by window.
```toml Winit is designed to be a low-level brick in a hierarchy of libraries. Consequently, in order to
[dependencies] show something on the window you need to use the platform-specific getters provided by winit, or
gl = "*" another library.
libc = "*"
```
```rust ```rust
extern crate gl; extern crate winit;
extern crate glutin;
extern crate libc;
fn main() { fn main() {
let window = glutin::Window::new().unwrap(); let window = winit::Window::new().unwrap();
unsafe { window.make_current() };
unsafe {
gl::load_with(|symbol| window.get_proc_address(symbol) as *const _);
gl::ClearColor(0.0, 1.0, 0.0, 1.0);
}
for event in window.wait_events() { for event in window.wait_events() {
unsafe { gl::Clear(gl::COLOR_BUFFER_BIT) };
window.swap_buffers();
match event { match event {
glutin::Event::Closed => break, winit::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`
### X11
- The plan is that glutin tries to dynamically link-to and use wayland if possible. If it doesn't work, it will try xlib instead. If it doesn't work, it will try libcaca. This is work-in-progress.
