```bash
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 a 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.
