## Usage
|
|
|
|
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 movement, etc.)
|
|
produced by window.
|
|
|
|
Winit is designed to be a low-level brick in a hierarchy of libraries. Consequently, in order to
|
|
show something on the window you need to use the platform-specific getters provided by winit, or
|
|
another library.
|
|
|
|
```rust
|
|
use winit::{
|
|
event::{Event, WindowEvent},
|
|
event_loop::{ControlFlow, EventLoop},
|
|
window::WindowBuilder,
|
|
};
|
|
|
|
fn main() {
|
|
let event_loop = EventLoop::new();
|
|
let window = WindowBuilder::new().build(&event_loop).unwrap();
|
|
|
|
event_loop.run(move |event, _, control_flow| {
|
|
*control_flow = ControlFlow::Wait;
|
|
|
|
match event {
|
|
Event::WindowEvent {
|
|
event: WindowEvent::CloseRequested,
|
|
window_id,
|
|
} if window_id == window.id() => *control_flow = ControlFlow::Exit,
|
|
_ => (),
|
|
}
|
|
});
|
|
}
|
|
```
|
|
|
|
Winit is only officially supported on the latest stable version of the Rust compiler.
|
|
|
|
### Cargo Features
|
|
|
|
Winit provides the following features, which can be enabled in your `Cargo.toml` file:
|
|
* `serde`: Enables serialization/deserialization of certain types with [Serde](https://crates.io/crates/serde).
|
|
* `x11` (enabled by default): On Unix platform, compiles with the X11 backend
|
|
* `wayland` (enabled by default): On Unix platform, compiles with the Wayland backend
|
|
|
|
### Platform-specific usage
|
|
|
|
#### WebAssembly
|
|
|
|
Building a binary will yield a `.js` file. In order to use it in an HTML file, you need to:
|
|
|
|
- Put a `<canvas id="my_id"></canvas>` element somewhere. A canvas corresponds to a winit "window".
|
|
- Write a Javascript code that creates a global variable named `Module`. Set `Module.canvas` to
|
|
the element of the `<canvas>` element (in the example you would retrieve it via `document.getElementById("my_id")`).
|
|
More information [here](https://kripken.github.io/emscripten-site/docs/api_reference/module.html).
|
|
- Make sure that you insert the `.js` file generated by Rust after the `Module` variable is created.
|
|
|
|
#### Android
|
|
|
|
This library makes use of the [ndk-rs](https://github.com/rust-windowing/android-ndk-rs) crates, refer to that repo for more documentation.
|
|
|
|
Running on an Android device needs a dynamic system library, add this to Cargo.toml:
|
|
```toml
|
|
[[example]]
|
|
name = "request_redraw_threaded"
|
|
crate-type = ["cdylib"]
|
|
```
|
|
|
|
And add this to the example file to add the native activity glue:
|
|
```rust
|
|
#[cfg(target_os = "android")]
|
|
ndk_glue::ndk_glue!(main);
|
|
```
|
|
|
|
And run the application with `cargo apk run --example request_redraw_threaded`
|
