From the "Smooth Scrolling" section of [XI2Proto.txt][1]: > One unit of scrolling in either direction is considered to be equivalent to > one button event, e.g. for a unit size of 1.0, -2.0 on an valuator type > Vertical sends two button press/release events for button 4. Likewise, a > button press event for button 7 generates an event on the Horizontal > valuator with a value of +1.0. The server may accumulate deltas of less than > one unit of scrolling. From [What's new in XI 2.1 - smooth scrolling][2]: > The increment defines what delta the driver considers to be one scroll > event. For an increment of +5, each delta of 5 should be regarded as one > scroll unit down. For an increment of -3, each delta of 3 should be regarded > as one scroll unit up (i.e. inverted).

glutin - OpenGL, UTilities and INput
![Gitter](https://badges.gitter.im/Join Chat.svg)
Alternative to GLFW in pure Rust.
[dependencies]
glutin = "*"
Documentation
Try it!
git clone https://github.com/tomaka/glutin
cd glutin
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() };
unsafe {
gl::load_with(|symbol| window.get_proc_address(symbol));
gl::ClearColor(0.0, 1.0, 0.0, 1.0);
}
for event in window.wait_events() {
unsafe { 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 runcargo build
, then go back toglutin
and callANDROID_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.
