+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+Please keep one empty line before and after all headers. (This is required for
+`git` to produce a conflict when a release is made while a PR is open and the
+PR's changelog entry would go into the wrong section).
+
+And please only add new entries to the top of this list, right below the `#
+Unreleased` header.
+
+# Unreleased
+
+- On X11, fix swapped instance and general class names.
+- **Breaking:** Removed unnecessary generic parameter `T` from `EventLoopWindowTarget`.
+- On Windows, macOS, X11, Wayland and Web, implement setting images as cursors. See the `custom_cursors.rs` example.
+  - **Breaking:** Remove `Window::set_cursor_icon`
+  - Add `WindowBuilder::with_cursor` and `Window::set_cursor` which takes a `CursorIcon` or `CustomCursor`
+  - Add `CustomCursor`
+  - Add `CustomCursor::from_rgba` to allow creating cursor images from RGBA data.
+  - Add `CustomCursorExtWebSys::from_url` to allow loading cursor images from URLs.
+  - Add `CustomCursorExtWebSys::from_animation` to allow creating animated cursors from other `CustomCursor`s.
+- On macOS, add services menu.
+- **Breaking:** On Web, remove queuing fullscreen request in absence of transient activation.
+- On Web, fix setting cursor icon overriding cursor visibility.
+- **Breaking:** On Web, return `RawWindowHandle::WebCanvas` instead of `RawWindowHandle::Web`.
+- **Breaking:** On Web, macOS and iOS, return `HandleError::Unavailable` when a window handle is not available.
+- **Breaking:** Bump MSRV from `1.65` to `1.70`.
+- On Web, add the ability to toggle calling `Event.preventDefault()` on `Window`.
+- **Breaking:** Remove `WindowAttributes::fullscreen()` and expose as field directly.

+- Build docs on `docs.rs` for iOS and Android as well.
+- **Breaking:** Removed the `WindowAttributes` struct, since all its functionality is accessible from `WindowBuilder`.
+- Added `WindowBuilder::transparent` getter to check if the user set `transparent` attribute.
+- On macOS, Fix emitting `Event::LoopDestroyed` on CMD+Q.
+- On macOS, fixed an issue where having multiple windows would prevent run_return from ever returning.
+- On Wayland, fix bug where the cursor wouldn't hide in GNOME.
+- On macOS, Windows, and Wayland, add `set_cursor_hittest` to let the window ignore mouse events.
+- On Windows, added `WindowExtWindows::set_skip_taskbar` and `WindowBuilderExtWindows::with_skip_taskbar`.

+- Remove no longer needed `WINIT_LINK_COLORSYNC` environment variable.
+- **Breaking:** Rename the `Exit` variant of `ControlFlow` to `ExitWithCode`, which holds a value to control the exit code after running. Add an `Exit` constant which aliases to `ExitWithCode(0)` instead to avoid major breakage. This shouldn't affect most existing programs.
+- Add `EventLoopBuilder`, which allows you to create and tweak the settings of an event loop before creating it.
+- Deprecated `EventLoop::with_user_event`; use `EventLoopBuilder::with_user_event` instead.
+- **Breaking:** Replaced `EventLoopExtMacOS` with `EventLoopBuilderExtMacOS` (which also has renamed methods).
+- **Breaking:** Replaced `EventLoopExtWindows` with `EventLoopBuilderExtWindows` (which also has renamed methods).
+- **Breaking:** Replaced `EventLoopExtUnix` with `EventLoopBuilderExtUnix` (which also has renamed methods).
+- **Breaking:** The platform specific extensions for Windows `winit::platform::windows` have changed. All `HANDLE`-like types e.g. `HWND` and `HMENU` were converted from winapi types or `*mut c_void` to `isize`. This was done to be consistent with the type definitions in windows-sys and to not expose internal dependencies.
+- The internal bindings to the [Windows API](https://docs.microsoft.com/en-us/windows/) were changed from the unofficial [winapi](https://github.com/retep998/winapi-rs) bindings to the official Microsoft [windows-sys](https://github.com/microsoft/windows-rs) bindings.

+- **Breaking:** Replaced `Window::with_app_id` and `Window::with_class` with `Window::with_name` on `WindowBuilderExtUnix`.
+- On Wayland, fallback CSD was replaced with proper one:
+  - `WindowBuilderExtUnix::with_wayland_csd_theme` to set color theme in builder.
+  - `WindowExtUnix::wayland_set_csd_theme` to set color theme when creating a window.
+  - `WINIT_WAYLAND_CSD_THEME` env variable was added, it can be used to set "dark"/"light" theme in apps that don't expose theme setting.
+  - `wayland-csd-adwaita` feature that enables proper CSD with title rendering using FreeType system library.

+- Added `Window::set_ime_allowed` supported on desktop platforms.
+- **Breaking:** IME input on desktop platforms won't be received unless it's explicitly allowed via `Window::set_ime_allowed` and new `WindowEvent::Ime` events are handled.
+- On macOS, `WindowEvent::Resized` is now emitted in `frameDidChange` instead of `windowDidResize`.
+- **Breaking:** On X11, device events are now ignored for unfocused windows by default, use `EventLoopWindowTarget::set_device_event_filter` to set the filter level.
+- Implemented `Default` on `EventLoop<()>`.
+- Implemented `Eq` for `Fullscreen`, `Theme`, and `UserAttentionType`.
+- **Breaking:** `Window::set_cursor_grab` now accepts `CursorGrabMode` to control grabbing behavior.
+- On Wayland, add support for `Window::set_cursor_position`.
+- Fix on macOS `WindowBuilder::with_disallow_hidpi`, setting true or false by the user no matter the SO default value.
+- `EventLoopBuilder::build` will now panic when the `EventLoop` is being created more than once.
+- Added `From<u64>` for `WindowId` and `From<WindowId>` for `u64`.
+- Added `MonitorHandle::refresh_rate_millihertz` to get monitor's refresh rate.
+- **Breaking**, Replaced `VideoMode::refresh_rate` with `VideoMode::refresh_rate_millihertz` providing better precision.
+- On Web, add `with_prevent_default` and `with_focusable` to `WindowBuilderExtWebSys` to control whether events should be propagated.
+- On Windows, fix focus events being sent to inactive windows.
+- **Breaking**, update `raw-window-handle` to `v0.5` and implement `HasRawDisplayHandle` for `Window` and `EventLoopWindowTarget`.
+- On X11, add function `register_xlib_error_hook` into `winit::platform::unix` to subscribe for errors comming from Xlib.
+- On Android, upgrade `ndk` and `ndk-glue` dependencies to the recently released `0.7.0`.
+- All platforms can now be relied on to emit a `Resumed` event. Applications are recommended to lazily initialize graphics state and windows on first resume for portability.
+- **Breaking:**: Reverse horizontal scrolling sign in `MouseScrollDelta` to match the direction of vertical scrolling. A positive X value now means moving the content to the right. The meaning of vertical scrolling stays the same: a positive Y value means moving the content down.
+- On MacOS, fix deadlock when calling `set_maximized` from event loop.
+
+# 0.26.1 (2022-01-05)
+

+## Release process
+
+Given that winit is a widely used library, we should be able to make a patch
+releases at any time we want without blocking the development of new features.
+
+To achieve these goals, a new branch is created for every new release. Releases and later patch releases are committed and tagged in this branch.
+
+The exact steps for an exemplary `0.2.0` release might look like this:
+  1. Initially, the version on the latest master is `0.1.0`
+  2. A new `v0.2.x` branch is created for the release
+  3. In the branch, the version is bumped to `v0.2.0`
+  4. The new commit in the branch is tagged `v0.2.0`
+  5. The version is pushed to crates.io
+  6. A GitHub release is created for the `v0.2.0` tag
+  7. On master, the version is bumped to `0.2.0`, and the CHANGELOG is updated
+  
+When doing a patch release, the process is similar:
+  1. Initially, the version of the latest release is `0.2.0`
+  2. Checkout the `v0.2.x` branch
+  3. Cherry-pick the required non-breaking changes into the `v0.2.x`
+  4. Follow steps 3-7 of the regular release example

 ## 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.
+produced by the 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
+* `mint`: Enables mint (math interoperability standard types) conversions.
+
+## MSRV Policy
+
+This crate's Minimum Supported Rust Version (MSRV) is **1.70**. Changes to
+the MSRV will be accompanied by a minor version bump.
+
+As a **tentative** policy, the upper bound of the MSRV is given by the following
+formula:
+
+```
+min(sid, stable - 3)
+```
+
+Where `sid` is the current version of `rustc` provided by [Debian Sid], and
+`stable` is the latest stable version of Rust. This bound may be broken in case of a major ecosystem shift or a security vulnerability.
+
+[Debian Sid]: https://packages.debian.org/sid/rustc
+
+The exception is for the Android platform, where a higher Rust version
+must be used for certain Android features. In this case, the MSRV will be
+capped at the latest stable version of Rust minus three. This inconsistency is
+not reflected in Cargo metadata, as it is not powerful enough to expose this
+restriction.
+
+All crates in the [`rust-windowing`] organizations have the
+same MSRV policy.

 ### Platform-specific usage
 
-#### WebAssembly
+#### Wayland
 
-Winit supports compiling to the `wasm32-unknown-unknown` target with either a
-`stdweb` or a `web-sys` backend for use on web browsers. However, please note
-that **the `stdweb` backend is being deprecated and may be removed in a future
-release of Winit**. The `web-sys` backend is also more feature complete.
+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.

 #### 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.
+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:
 
-Running on an Android device needs a dynamic system library, add this to Cargo.toml:
 ```toml
-[[example]]
-name = "request_redraw_threaded"
+[lib]
+name = "main"
 crate-type = ["cdylib"]
 ```
 
-And add this to the example file to add the native activity glue:
-```rust
-#[cfg_attr(target_os = "android", ndk_glue::main(backtrace = "on"))]
-fn main() {
-    ...
-}
-```
+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:
 
-And run the application with `cargo apk run --example request_redraw_threaded`
+| 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`]) |

+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`.

-//! UI scaling is important, so read the docs for this module if you don't want to be confused.
-//!
-//! ## Why should I care about UI scaling?
-//!
-//! Modern computer screens don't have a consistent relationship between resolution and size.
-//! 1920x1080 is a common resolution for both desktop and mobile screens, despite mobile screens
-//! normally being less than a quarter the size of their desktop counterparts. What's more, neither
-//! desktop nor mobile screens are consistent resolutions within their own size classes - common
-//! mobile screens range from below 720p to above 1440p, and desktop screens range from 720p to 5K
-//! and beyond.
-//!
-//! Given that, it's a mistake to assume that 2D content will only be displayed on screens with
-//! a consistent pixel density. If you were to render a 96-pixel-square image on a 1080p screen,
-//! then render the same image on a similarly-sized 4K screen, the 4K rendition would only take up
-//! about a quarter of the physical space as it did on the 1080p screen. That issue is especially
-//! problematic with text rendering, where quarter-sized text becomes a significant legibility
-//! problem.
-//!
-//! Failure to account for the scale factor can create a significantly degraded user experience.
-//! Most notably, it can make users feel like they have bad eyesight, which will potentially cause
-//! them to think about growing elderly, resulting in them having an existential crisis. Once users
-//! enter that state, they will no longer be focused on your application.
-//!
-//! ## How should I handle it?
-//!
-//! The solution to this problem is to account for the device's *scale factor*. The scale factor is
-//! the factor UI elements should be scaled by to be consistent with the rest of the user's system -
-//! for example, a button that's normally 50 pixels across would be 100 pixels across on a device
-//! with a scale factor of `2.0`, or 75 pixels across with a scale factor of `1.5`.
-//!
-//! Many UI systems, such as CSS, expose DPI-dependent units like [points] or [picas]. That's
-//! usually a mistake, since there's no consistent mapping between the scale factor and the screen's
-//! actual DPI. Unless you're printing to a physical medium, you should work in scaled pixels rather
-//! than any DPI-dependent units.
-//!
-//! ### Position and Size types
-//!
-//! Winit's `Physical(Position|Size)` types correspond with the actual pixels on the device, and the
-//! `Logical(Position|Size)` types correspond to the physical pixels divided by the scale factor.
-//! All of Winit's functions return physical types, but can take either logical or physical
-//! coordinates as input, allowing you to use the most convenient coordinate system for your
-//! particular application.
-//!
-//! Winit's position and size types types are generic over their exact pixel type, `P`, to allow the
-//! API to have integer precision where appropriate (e.g. most window manipulation functions) and
-//! floating precision when necessary (e.g. logical sizes for fractional scale factors and touch
-//! input). If `P` is a floating-point type, please do not cast the values with `as {int}`. Doing so
-//! will truncate the fractional part of the float, rather than properly round to the nearest
-//! integer. Use the provided `cast` function or `From`/`Into` conversions, which handle the
-//! rounding properly. Note that precision loss will still occur when rounding from a float to an
-//! int, although rounding lessens the problem.
-//!
-//! ### Events
-//!
-//! Winit will dispatch a [`ScaleFactorChanged`](crate::event::WindowEvent::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 gives you a chance 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`](crate::event::WindowEvent::ScaleFactorChanged) event,
-//! then its scale factor is `1.0`.
-//!
-//! ## How is the scale factor calculated?
-//!
-//! 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:** "retina displays" have a scale factor of 2.0. Otherwise, the scale factor is 1.0.
-//!   Intermediate scale factors are never used. It's possible for any display to use that 2.0 scale
-//!   factor, given the use of the command line.
-//! - **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, calcuate 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:** On Wayland, scale factors are set per-screen by the server, and are always
-//!   integers (most often 1 or 2).
-//! - **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`.

-// Normally when you run or distribute a macOS app, it's bundled: it's in one
-// of those fun little folders that you have to right click "Show Package
-// Contents" on, and usually contains myriad delights including, but not
-// limited to, plists, icons, and of course, your beloved executable. However,
-// when you use `cargo run`, your app is unbundled - it's just a lonely, bare
-// executable.
-//
-// Apple isn't especially fond of unbundled apps, which is to say, they seem to
-// barely be supported. If you move the mouse while opening a winit window from
-// an unbundled app, the window will fail to activate and be in a grayed-out
-// uninteractable state. Switching to another app and back is the only way to
-// get the winit window into a normal state. None of this happens if the app is
-// bundled, i.e. when running via Xcode.
-//
-// To workaround this, we just switch focus to the Dock and then switch back to
-// our app. We only do this for unbundled apps, and only when they fail to
-// become active on their own.
-//
-// This solution was derived from this Godot PR:
-// https://github.com/godotengine/godot/pull/17187
-// (which appears to be based on https://stackoverflow.com/a/7602677)
-// The curious specialness of mouse motions is touched upon here:
-// https://github.com/godotengine/godot/issues/8653#issuecomment-358130512
-//
-// We omit the 2nd step of the solution used in Godot, since it appears to have
-// no effect - I speculate that it's just technical debt picked up from the SO
-// answer; the API used is fairly exotic, and was historically used for very
-// old versions of macOS that didn't support `activateIgnoringOtherApps`, i.e.
-// in previous versions of SDL:
-// https://hg.libsdl.org/SDL/file/c0bcc39a3491/src/video/cocoa/SDL_cocoaevents.m#l322
-//
-// The `performSelector` delays in the Godot solution are used for sequencing,
-// since refocusing the app will fail if the call is made before it finishes
-// unfocusing. The delays used there are much smaller than the ones in the
-// original SO answer, presumably because they found the fastest delay that
-// works reliably through trial and error. Instead of using delays, we just
-// handle `applicationDidResignActive`; despite the app not activating reliably,
-// that still triggers when we switch focus to the Dock.
-//
-// The Godot solution doesn't appear to skip the hack when an unbundled app
-// activates normally. Checking for this is difficult, since if you call
-// `isActive` too early, it will always be `NO`. Even though we receive
-// `applicationDidResignActive` when switching focus to the Dock, we never
-// receive a preceding `applicationDidBecomeActive` if the app fails to
-// activate normally. I wasn't able to find a proper point in time to perform
-// the `isActive` check, so we instead check for the cause of the quirk: if
-// any mouse motion occurs prior to us receiving `applicationDidResignActive`,
-// we assume the app failed to become active.
-//
-// Fun fact: this issue is still present in GLFW
-// (https://github.com/glfw/glfw/issues/1515)
-//
-// A similar issue was found in SDL, but the resolution doesn't seem to work
-// for us: https://bugzilla.libsdl.org/show_bug.cgi?id=3051
