 ### Platform-specific usage
 
-Check out the [`winit::platform`](https://rust-windowing.github.io/winit/winit/platform/index.html) module for platform-specific usage.
+#### Wayland
+
+Note that windows don't appear on Wayland until you draw/present to them.
+
+#### Web
+
+To run the web example: `cargo run-wasm --example web`
+
+Winit supports compiling to the `wasm32-unknown-unknown` target with `web-sys`.
+
+On the web platform, a Winit window is backed by a `<canvas>` element. You can
+either [provide Winit with a `<canvas>` element][web with_canvas], or [let Winit
+create a `<canvas>` element which you can then retrieve][web canvas getter] and
+insert it into the DOM yourself.
+
+For the example code using Winit on Web, check out the [web example]. For
+information on using Rust on WebAssembly, check out the [Rust and WebAssembly
+book].
+
+[web with_canvas]: https://docs.rs/winit/latest/wasm32-unknown-unknown/winit/platform/web/trait.WindowBuilderExtWebSys.html#tymethod.with_canvas
+[web canvas getter]: https://docs.rs/winit/latest/wasm32-unknown-unknown/winit/platform/web/trait.WindowExtWebSys.html#tymethod.canvas
+[web example]: ./examples/web.rs
+[Rust and WebAssembly book]: https://rustwasm.github.io/book/
+
+#### Android
+
+The Android backend builds on (and exposes types from) the [`ndk`](https://docs.rs/ndk/latest/ndk/) crate.
+
+Native Android applications need some form of "glue" crate that is responsible
+for defining the main entry point for your Rust application as well as tracking
+various life-cycle events and synchronizing with the main JVM thread.
+
+Winit uses the [android-activity](https://github.com/rib/android-activity) as a
+glue crate (prior to `0.28` it used
+[ndk-glue](https://github.com/rust-windowing/android-ndk-rs/tree/master/ndk-glue)).
+
+The version of the glue crate that your application depends on _must_ match the
+version that Winit depends on because the glue crate is responsible for your
+application's main entry point. If Cargo resolves multiple versions, they will
+clash.
+
+`winit` glue compatibility table:
+
+| winit |       ndk-glue               |
+| :---: | :--------------------------: |
+| 0.29  | `android-activity = "0.5"`   |
+| 0.28  | `android-activity = "0.4"`   |
+| 0.27  | `ndk-glue = "0.7"`           |
+| 0.26  | `ndk-glue = "0.5"`           |
+| 0.25  | `ndk-glue = "0.3"`           |
+| 0.24  | `ndk-glue = "0.2"`           |
+
+The recommended way to avoid a conflict with the glue version is to avoid explicitly
+depending on the `android-activity` crate, and instead consume the API that
+is re-exported by Winit under `winit::platform::android::activity::*`
+
+Running on an Android device needs a dynamic system library. Add this to Cargo.toml:
+
+```toml
+[lib]
+name = "main"
+crate-type = ["cdylib"]
+```
+
+All Android applications are based on an `Activity` subclass, and the
+`android-activity` crate is designed to support different choices for this base
+class. Your application _must_ specify the base class it needs via a feature flag:
+
+| Base Class       | Feature Flag      |  Notes  |
+| :--------------: | :---------------: | :-----: |
+| `NativeActivity` | `android-native-activity` | Built-in to Android - it is possible to use without compiling any Java or Kotlin code. Java or Kotlin code may be needed to subclass `NativeActivity` to access some platform features. It does not derive from the [`AndroidAppCompat`] base class.|
+| [`GameActivity`] | `android-game-activity`   | Derives from [`AndroidAppCompat`], a defacto standard `Activity` base class that helps support a wider range of Android versions. Requires a build system that can compile Java or Kotlin and fetch Android dependencies from a [Maven repository][agdk_jetpack] (or link with an embedded [release][agdk_releases] of [`GameActivity`]) |
+
+[`GameActivity`]: https://developer.android.com/games/agdk/game-activity
+[`GameTextInput`]: https://developer.android.com/games/agdk/add-support-for-text-input
+[`AndroidAppCompat`]: https://developer.android.com/reference/androidx/appcompat/app/AppCompatActivity
+[agdk_jetpack]: https://developer.android.com/jetpack/androidx/releases/games
+[agdk_releases]: https://developer.android.com/games/agdk/download#agdk-libraries
+[Gradle]: https://developer.android.com/studio/build
+
+For more details, refer to these `android-activity` [example applications](https://github.com/rust-mobile/android-activity/tree/main/examples).
+
+##### Converting from `ndk-glue` to `android-activity`
+
+If your application is currently based on `NativeActivity` via the `ndk-glue` crate and building with `cargo apk`, then the minimal changes would be:
+1. Remove `ndk-glue` from your `Cargo.toml`
+2. Enable the `"android-native-activity"` feature for Winit: `winit = { version = "0.29.10", features = [ "android-native-activity" ] }`
+3. Add an `android_main` entrypoint (as above), instead of using the '`[ndk_glue::main]` proc macro from `ndk-macros` (optionally add a dependency on `android_logger` and initialize logging as above).
+4. Pass a clone of the `AndroidApp` that your application receives to Winit when building your event loop (as shown above).
+
+#### MacOS
+
+A lot of functionality expects the application to be ready before you start
+doing anything; this includes creating windows, fetching monitors, drawing,
+and so on, see issues [#2238], [#2051] and [#2087].
+
+If you encounter problems, you should try doing your initialization inside
+`Event::Resumed`.
+
+#### iOS
+
+Similar to macOS, iOS's main `UIApplicationMain` does some init work that's required
+by all UI-related code (see issue [#1705]). It would be best to consider creating your windows
+inside `Event::Resumed`.

-//! # Android
-//!
-//! The Android backend builds on (and exposes types from) the [`ndk`](https://docs.rs/ndk/) crate.
-//!
-//! Native Android applications need some form of "glue" crate that is responsible
-//! for defining the main entry point for your Rust application as well as tracking
-//! various life-cycle events and synchronizing with the main JVM thread.
-//!
-//! Winit uses the [android-activity](https://docs.rs/android-activity/) as a
-//! glue crate (prior to `0.28` it used
-//! [ndk-glue](https://github.com/rust-windowing/android-ndk-rs/tree/master/ndk-glue)).
-//!
-//! The version of the glue crate that your application depends on _must_ match the
-//! version that Winit depends on because the glue crate is responsible for your
-//! application's main entry point. If Cargo resolves multiple versions, they will
-//! clash.
-//!
-//! `winit` glue compatibility table:
-//!
-//! | winit |       ndk-glue               |
-//! | :---: | :--------------------------: |
-//! | 0.29  | `android-activity = "0.5"`   |
-//! | 0.28  | `android-activity = "0.4"`   |
-//! | 0.27  | `ndk-glue = "0.7"`           |
-//! | 0.26  | `ndk-glue = "0.5"`           |
-//! | 0.25  | `ndk-glue = "0.3"`           |
-//! | 0.24  | `ndk-glue = "0.2"`           |
-//!
-//! The recommended way to avoid a conflict with the glue version is to avoid explicitly
-//! depending on the `android-activity` crate, and instead consume the API that
-//! is re-exported by Winit under `winit::platform::android::activity::*`
-//!
-//! Running on an Android device needs a dynamic system library. Add this to Cargo.toml:
-//!
-//! ```toml
-//! [lib]
-//! name = "main"
-//! crate-type = ["cdylib"]
-//! ```
-//!
-//! All Android applications are based on an `Activity` subclass, and the
-//! `android-activity` crate is designed to support different choices for this base
-//! class. Your application _must_ specify the base class it needs via a feature flag:
-//!
-//! | Base Class       | Feature Flag      |  Notes  |
-//! | :--------------: | :---------------: | :-----: |
-//! | `NativeActivity` | `android-native-activity` | Built-in to Android - it is possible to use without compiling any Java or Kotlin code. Java or Kotlin code may be needed to subclass `NativeActivity` to access some platform features. It does not derive from the [`AndroidAppCompat`] base class.|
-//! | [`GameActivity`] | `android-game-activity`   | Derives from [`AndroidAppCompat`], a defacto standard `Activity` base class that helps support a wider range of Android versions. Requires a build system that can compile Java or Kotlin and fetch Android dependencies from a [Maven repository][agdk_jetpack] (or link with an embedded [release][agdk_releases] of [`GameActivity`]) |

-//! ## Converting from `ndk-glue` to `android-activity`
-//!
-//! If your application is currently based on `NativeActivity` via the `ndk-glue` crate and building with `cargo apk`, then the minimal changes would be:
-//! 1. Remove `ndk-glue` from your `Cargo.toml`
-//! 2. Enable the `"android-native-activity"` feature for Winit: `winit = { version = "0.29.11", features = [ "android-native-activity" ] }`
-//! 3. Add an `android_main` entrypoint (as above), instead of using the '`[ndk_glue::main]` proc macro from `ndk-macros` (optionally add a dependency on `android_logger` and initialize logging as above).
-//! 4. Pass a clone of the `AndroidApp` that your application receives to Winit when building your event loop (as shown above).

-/// Re-export of the `android_activity` API
-///

-/// applications can rely on the Winit crate to resolve the required version of
-/// `android_activity` and avoid any chance of a conflict between Winit and the
-/// application crate.
-///
-/// Unlike most libraries there can only be a single implementation
-/// of the `android_activity` glue crate linked with an application because
-/// it is responsible for the application's `android_main()` entry point.
-///
-/// Since Winit depends on a specific version of `android_activity` the simplest
-/// way to avoid creating a conflict is for applications to avoid explicitly
-/// depending on the `android_activity` crate, and instead consume the API that
-/// is re-exported by Winit.
-///
-/// For compatibility applications should then import the `AndroidApp` type for
-/// their `android_main(app: AndroidApp)` function like:
-/// ```rust
-/// #[cfg(target_os="android")]
-/// use winit::platform::android::activity::AndroidApp;

-//! ## Cargo Features

 //!
-//! This crate provides the following Cargo features:
+//! Winit will dispatch a [`ScaleFactorChanged`] event whenever a window's scale factor has changed.
+//! This can happen if the user drags their window from a standard-resolution monitor to a high-DPI
+//! monitor or if the user changes their DPI settings. This allows you to rescale your application's
+//! UI elements and adjust how the platform changes the window's size to reflect the new scale
+//! factor. If a window hasn't received a [`ScaleFactorChanged`] event, its scale factor
+//! can be found by calling [`window.scale_factor()`].

+//! ## How is the scale factor calculated?
-//!   [Serde](https://crates.io/crates/serde).
+//!
-//! * `mint`: Enables mint (math interoperability standard types) conversions.
+//! The scale factor is calculated differently on different platforms:
+//!
+//! - **Windows:** On Windows 8 and 10, per-monitor scaling is readily configured by users from the
+//!   display settings. While users are free to select any option they want, they're only given a
+//!   selection of "nice" scale factors, i.e. 1.0, 1.25, 1.5... on Windows 7. The scale factor is
+//!   global and changing it requires logging out. See [this article][windows_1] for technical
+//!   details.
+//! - **macOS:** Recent macOS versions allow the user to change the scaling factor for specific
+//!   displays. When available, the user may pick a per-monitor scaling factor from a set of
+//!   pre-defined settings. All "retina displays" have a scaling factor above 1.0 by default,
+//!   but the specific value varies across devices.
+//! - **X11:** Many man-hours have been spent trying to figure out how to handle DPI in X11. Winit
+//!   currently uses a three-pronged approach:
+//!   + Use the value in the `WINIT_X11_SCALE_FACTOR` environment variable if present.
+//!   + If not present, use the value set in `Xft.dpi` in Xresources.
+//!   + Otherwise, calculate the scale factor based on the millimeter monitor dimensions provided by XRandR.
+//!
+//!   If `WINIT_X11_SCALE_FACTOR` is set to `randr`, it'll ignore the `Xft.dpi` field and use the
+//!   XRandR scaling method. Generally speaking, you should try to configure the standard system
+//!   variables to do what you want before resorting to `WINIT_X11_SCALE_FACTOR`.
+//! - **Wayland:** The scale factor is suggested by the compositor for each window individually. The
+//!   monitor scale factor may differ from the window scale factor.
+//! - **iOS:** Scale factors are set by Apple to the value that best suits the device, and range
+//!   from `1.0` to `3.0`. See [this article][apple_1] and [this article][apple_2] for more
+//!   information.
+//! - **Android:** Scale factors are set by the manufacturer to the value that best suits the
+//!   device, and range from `1.0` to `4.0`. See [this article][android_1] for more information.
+//! - **Web:** The scale factor is the ratio between CSS pixels and the physical device pixels.
+//!   In other words, it is the value of [`window.devicePixelRatio`][web_1]. It is affected by
+//!   both the screen scaling and the browser zoom level and can go below `1.0`.

+This example draws a circle in the middle of a 4/1 aspect ratio canvas which acts as a useful demonstration of winit's resize handling on web.
+Even when the browser window is resized or aspect-ratio of the canvas changed the circle should always:
+* Fill the entire width or height of the canvas (whichever is smaller) without exceeding it.
+* Be perfectly round
+* Not be blurry or pixelated (there is no antialiasing so you may still see jagged edges depending on the DPI of your monitor)
+
+Currently winit does not handle resizes on web so the circle is rendered incorrectly.
+This example demonstrates the desired future functionality which will possibly be provided by https://github.com/rust-windowing/winit/pull/2074

-//! # iOS / UIKit
-//!
-//! Winit has an OS requirement of iOS 8 or higher, and is regularly tested on
-//! iOS 9.3.
-//!
-//! iOS's main `UIApplicationMain` does some init work that's required by all
-//! UI-related code (see issue [#1705]). It is best to create your windows
-//! inside `Event::Resumed`.
-//!
-//! [#1705]: https://github.com/rust-windowing/winit/issues/1705
-//!
-//! ## Building app
-//!
-//! To build ios app you will need rustc built for this targets:
-//!
-//!  - armv7-apple-ios
-//!  - armv7s-apple-ios
-//!  - i386-apple-ios
-//!  - aarch64-apple-ios
-//!  - x86_64-apple-ios
-//!
-//! Then
-//!
-//! ```
-//! cargo build --target=...
-//! ```
-//! The simplest way to integrate your app into xcode environment is to build it
-//! as a static library. Wrap your main function and export it.
-//!
-//! ```rust, ignore
-//! #[no_mangle]
-//! pub extern fn start_winit_app() {
-//!     start_inner()
-//! }
-//!
-//! fn start_inner() {
-//!    ...
-//! }
-//! ```
-//!
-//! Compile project and then drag resulting .a into Xcode project. Add winit.h to xcode.
-//!
-//! ```ignore
-//! void start_winit_app();
-//! ```
-//!
-//! Use start_winit_app inside your xcode's main function.
-//!
-//!
-//! ## App lifecycle and events
-//!
-//! iOS environment is very different from other platforms and you must be very
-//! careful with it's events. Familiarize yourself with
-//! [app lifecycle](https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplicationDelegate_Protocol/).
-//!
-//! This is how those event are represented in winit:
-//!
-//!  - applicationDidBecomeActive is Resumed
-//!  - applicationWillResignActive is Suspended
-//!  - applicationWillTerminate is LoopExiting
-//!
-//! Keep in mind that after LoopExiting event is received every attempt to draw with
-//! opengl will result in segfault.
-//!
-//! Also note that app may not receive the LoopExiting event if suspended; it might be SIGKILL'ed.
