f8efe87c34 Set WM_CLASS and WM_NAME before mapping window
ICCCM 4.1.2.5 (https://tronche.com/gui/x/icccm/sec-4.html#WM_CLASS)
states that:

> This property must be present when the window leaves the Withdrawn
> state and may be changed only while the window is in the Withdrawn
> state.

Previously, we would first map the window, and then set these
properties, causing sadness for window managers (#167,
tomaka/glutin#879). This patch changes that by setting the class and
name attributes immediately after the window is created, and before it
is mapped.

Fixes #167.

# Winit Contributing Guidelines
## Scope
[See `FEATURES.md`](./FEATURES.md). When requesting or implementing a new Winit feature, you should
consider whether or not it's directly related to window creation or input handling. If it isn't, it
may be worth creating a separate crate that extends Winit's API to add that functionality.
## Reporting an issue
When reporting an issue, in order to help the maintainers understand what the problem is, please make
your description of the issue as detailed as possible:
- if it is a bug, please provide a clear explanation of what happens, what should happen, and how to
reproduce the issue, ideally by providing a minimal program exhibiting the problem
- if it is a feature request, please provide a clear argumentation about why you believe this feature
should be supported by winit
## Making a pull request
When making a code contribution to winit, before opening your pull request, please make sure that:
- your patch builds with Winit's minimal supported rust version - Rust 1.70.
- you tested your modifications on all the platforms impacted, or if not possible, detail which platforms
were not tested, and what should be tested, so that a maintainer or another contributor can test them
- you updated any relevant documentation in winit
- you left comments in your code explaining any part that is not straightforward, so that the
maintainers and future contributors don't have to try to guess what your code is supposed to do
- your PR adds an entry to the changelog file if the introduced change is relevant to winit users.
You needn't worry about the added entry causing conflicts, the maintainer that merges the PR will
handle those for you when merging (see below).
- if your PR affects the platform compatibility of one or more features or adds another feature, the
relevant sections in [`FEATURES.md`](https://github.com/rust-windowing/winit/blob/master/FEATURES.md#features)
should be updated.
Once your PR is open, you can ask for a review by a maintainer of your platform. Winit's merging policy
is that a PR must be approved by at least two maintainers of winit before being merged, including
at least a maintainer of the platform (a maintainer making a PR themselves counts as approving it).
Once your PR is deemed ready, the merging maintainer will take care of resolving conflicts in
`CHANGELOG.md` (but you must resolve other conflicts yourself). Doing this requires that you check the
"give contributors write access to the branch" checkbox when creating the PR.
## Maintainers & Testers
The current maintainers are listed in the [CODEOWNERS](.github/CODEOWNERS) file.
If you are interested in being pinged when testing is needed for a specific platform, please add yourself to the [Testers and Contributors](https://github.com/rust-windowing/winit/wiki/Testers-and-Contributors) table!
## 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

# Winit Scope
Winit aims to expose an interface that abstracts over window creation and input handling and can
be used to create both games and applications. It supports the following main graphical platforms:
- Desktop
- Windows 7+ (10+ is tested regularly)
- macOS 10.7+ (10.14+ is tested regularly)
- Unix
- via X11
- via Wayland
- Redox OS, via Orbital
- Mobile
- iOS
- Android
- Web
- Chrome
- Firefox
- Safari 13.1+
Most platforms expose capabilities that cannot be meaningfully transposed onto others. Winit does not
aim to support every single feature of every platform, but rather to abstract over the common features
available everywhere. In this context, APIs exposed in winit can be split into different "support tiers":
- **Core:** Features that are essential to providing a well-formed abstraction over each platform's
windowing and input APIs.
- **Platform:** Platform-specific features that can't be meaningfully exposed through a common API and
cannot be implemented outside of Winit without exposing a significant amount of Winit's internals
or interfering with Winit's abstractions.
- **Usability:** Features that are not strictly essential to Winit's functionality, but provide meaningful
usability improvements and cannot be reasonably implemented in an external crate. These are
generally optional and exposed through Cargo features.
Core features are taken care of by the core Winit maintainers. Platform features are not.
When a platform feature is submitted, the submitter is considered the expert in the
feature and may be asked to support the feature should it break in the future.
Winit ***does not*** directly expose functionality for drawing inside windows or creating native
menus, but ***does*** commit to providing APIs that higher-level crates can use to implement that
functionality.
## `1.0` and stability
When all core features are implemented to the satisfaction of the Winit maintainers, Winit 1.0 will
be released and the library will enter maintenance mode. For the most part, new core features will not
be added past this point. New platform features may be accepted and exposed through point releases.
### Tier upgrades
Some platform features could, in theory, be exposed across multiple platforms, but have not gone
through the implementation work necessary to function on all platforms. When one of these features
gets implemented across all platforms, a PR can be opened to upgrade the feature to a core feature.
If that gets accepted, the platform-specific functions get deprecated and become permanently
exposed through the core, cross-platform API.
# Features
## Extending this section
If your PR makes notable changes to Winit's features, please update this section as follows:
- If your PR adds a new feature, add a brief description to the relevant section. If the feature is a core
feature, add a row to the feature matrix and describe what platforms the feature has been implemented on.
- If your PR begins a new API rework, add a row to the `Pending API Reworks` table. If the PR implements the
API rework on all relevant platforms, please move it to the `Completed API Reworks` table.
- If your PR implements an already-existing feature on a new platform, either mark the feature as *completed*,
or mark it as *mostly completed* and link to an issue describing the problems with the implementation.
## Core
### Windowing
- **Window initialization**: Winit allows the creation of a window
- **Providing pointer to init OpenGL**: Winit provides the necessary pointers to initialize a working opengl context
- **Providing pointer to init Vulkan**: Same as OpenGL but for Vulkan
- **Window decorations**: The windows created by winit are properly decorated, and the decorations can
be deactivated
- **Window decorations toggle**: Decorations can be turned on or off after window creation
- **Window resizing**: The windows created by winit can be resized and generate the appropriate events
when they are. The application can precisely control its window size if desired.
- **Window resize increments**: When the window gets resized, the application can choose to snap the window's
size to specific values.
- **Window transparency**: Winit allows the creation of windows with a transparent background.
- **Window maximization**: The windows created by winit can be maximized upon creation.
- **Window maximization toggle**: The windows created by winit can be maximized and unmaximized after
creation.
- **Window minimization**: The windows created by winit can be minimized after creation.
- **Fullscreen**: The windows created by winit can be put into fullscreen mode.
- **Fullscreen toggle**: The windows created by winit can be switched to and from fullscreen after
creation.
- **Exclusive fullscreen**: Winit allows changing the video mode of the monitor
for fullscreen windows and, if applicable, captures the monitor for exclusive
use by this application.
- **HiDPI support**: Winit assists developers in appropriately scaling HiDPI content.
- **Popup / modal windows**: Windows can be created relative to the client area of other windows, and parent
windows can be disabled in favor of popup windows. This feature also guarantees that popup windows
get drawn above their owner.
### System Information
- **Monitor list**: Retrieve the list of monitors and their metadata, including which one is primary.
- **Video mode query**: Monitors can be queried for their supported fullscreen video modes (consisting of resolution, refresh rate, and bit depth).
### Input Handling
- **Mouse events**: Generating mouse events associated with pointer motion, click, and scrolling events.
- **Mouse set location**: Forcibly changing the location of the pointer.
- **Cursor locking**: Locking the cursor inside the window so it cannot move.
- **Cursor confining**: Confining the cursor to the window bounds so it cannot leave them.
- **Cursor icon**: Changing the cursor icon or hiding the cursor.
- **Cursor image**: Changing the cursor to your own image.
- **Cursor hittest**: Handle or ignore mouse events for a window.
- **Touch events**: Single-touch events.
- **Touch pressure**: Touch events contain information about the amount of force being applied.
- **Multitouch**: Multi-touch events, including cancellation of a gesture.
- **Keyboard events**: Properly processing keyboard events using the user-specified keymap and
translating keypresses into UTF-8 characters, handling dead keys and IMEs.
- **Drag & Drop**: Dragging content into winit, detecting when content enters, drops, or if the drop is cancelled.
- **Raw Device Events**: Capturing input from input devices without any OS filtering.
- **Gamepad/Joystick events**: Capturing input from gamepads and joysticks.
- **Device movement events**: Capturing input from the device gyroscope and accelerometer.

show something on the window you need to use the platform-specific getters provided by winit, or show something on the window you need to use the platform-specific getters provided by winit, or
another library. another library.
### Cargo Features ```rust
extern crate winit;
Winit provides the following features, which can be enabled in your `Cargo.toml` file: fn main() {
* `serde`: Enables serialization/deserialization of certain types with [Serde](https://crates.io/crates/serde). let window = winit::Window::new().unwrap();
* `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:
for event in window.wait_events() {
match event {
winit::Event::Closed => break,
_ => ()
}
}
}
``` ```
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.
[`rust-windowing`]: https://github.com/rust-windowing
### 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`.
[#2238]: https://github.com/rust-windowing/winit/issues/2238
[#2051]: https://github.com/rust-windowing/winit/issues/2051
[#2087]: https://github.com/rust-windowing/winit/issues/2087
[#1705]: https://github.com/rust-windowing/winit/issues/1705
#### Redox OS
Redox OS has some functionality not yet present that will be implemented when
its orbital display server provides it.

//! Winit allows you to build a window on as many platforms as possible.
//!
//! # Building a window
//!
//! Before you can build a window, you first need to build an `EventsLoop`. This is done with the
//! `EventsLoop::new()` function. Example:
//!
//! ```no_run
//! use winit::EventsLoop;
//! let events_loop = EventsLoop::new();
//! ```
//!
//! Once this is done there are two ways to create a window:
//!
//! - Calling `Window::new(&events_loop)`.
//! - Calling `let builder = WindowBuilder::new()` then `builder.build(&events_loop)`.
//!
//! The first way is the simpliest way and will give you default values for everything.
//!
//! The second way allows you to customize the way your window will look and behave by modifying
//! the fields of the `WindowBuilder` object before you create the window.
//!
//! # Events handling
//!
//! Once a window has been created, it will *generate events*. For example whenever the user moves
//! the window, resizes the window, moves the mouse, etc. an event is generated.
//!
//! The events generated by a window can be retreived from the `EventsLoop` the window was created
//! with.
//!
//! There are two ways to do so. The first is to call `events_loop.poll_events(...)`, which will
//! retreive all the events pending on the windows and immediately return after no new event is
//! available. You usually want to use this method in application that render continuously on the
//! screen, such as video games.
//!
//! ```no_run
//! use winit::Event;
//! use winit::WindowEvent;
//! # use winit::EventsLoop;
//! # let events_loop = EventsLoop::new();
//!
//! loop {
//! events_loop.poll_events(|event| {
//! match event {
//! Event::WindowEvent { event: WindowEvent::Resized(w, h), .. } => {
//! println!("The window was resized to {}x{}", w, h);
//! },
//! _ => ()
//! }
//! });
//! }
//! ```
//!
//! The second way is to call `events_loop.run_forever(...)`. As its name tells, it will run
//! forever unless it is stopped by calling `events_loop.interrupt()`.
//!
//! ```no_run
//! use winit::Event;
//! use winit::WindowEvent;
//! # use winit::EventsLoop;
//! # let events_loop = EventsLoop::new();
//!
//! events_loop.run_forever(|event| {
//! match event {
//! Event::WindowEvent { event: WindowEvent::Closed, .. } => {
//! println!("The window was closed ; stopping");
//! events_loop.interrupt();
//! },
//! _ => ()
//! }
//! });
//! ```
//!
//! If you use multiple windows, the `WindowEvent` event has a member named `window_id`. You can
//! compare it with the value returned by the `id()` method of `Window` in order to know which
//! window has received the event.
//!
//! # Drawing on the window
//!
//! Winit doesn't provide any function that allows drawing on a window. However it allows you to
//! retreive the raw handle of the window (see the `os` module for that), which in turn allows you
//! to create an OpenGL/Vulkan/DirectX/Metal/etc. context that will draw on the window.
//!

//! iOS support
//!
//! # 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_glutin_app() {
//! start_inner()
//! }
//!
//! fn start_inner() {
//! ...
//! }
//!
//! ```
//!
//! Compile project and then drag resulting .a into Xcode project. Add glutin.h to xcode.
//!
//! ```ignore
//! void start_glutin_app();
//! ```
//!
//! Use start_glutin_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 glutin:
//!
//! - applicationDidBecomeActive is Focused(true)
