7f851fe433 Clarify scale_factor docs
Wayland scales each window individually, thus make it clear. Also
recommend against using the `MonitorHandle::scale_factor`.

8e9a3d2dd3 On Wayland, improve initial user size handling
Keep the user provided size in the original values and convert only
when we're getting a `configure` event. On some compositors will
have a scale available, so it'll work, however with some we'll
still have old 'pick 1` as default.

Also configure_bounds when compositor tells the user to pick the size,
that will ensure that initial `with_inner_size` won't grow beyond the
working area.

Fixes #3187.

08edda1b0b On X11, fix cursor_hittest not reloaded on Resize
The cursor hittest was not reloaded on window size changes, only
when `Window::request_inner_size` was called leading to regions
of the window being not clickable.

Also, don't try to apply hittest logic when user never requested a
hittest.

40ba9a7ce7 feat(windows): Fix inconsistency in mouse button device events, add hwheel device event on Windows
While working with device events, I noticed that there was an inconsistency in the mouse button device events between Windows/X11 and for example web, because web uses the same ids/order as the MouseButton enum, and Windows/X11 are using the X11 ids, and hwheel device event was ignored on Windows.

Mouse button device events are now using the same order as the MouseButton enum, and I also added hwheel device events for Windows.

74fcf7f9c0 On Windows, fix RedrawRequested delivery
When calling `Window::request_redraw` from the `RedrawRequested`
handler the `RedrawWindow` won't result in `WM_PAINT` being delivered
due since user callback is run before `DefWindowProcW` is called.

Track whether the user called `Window::request_redraw` and ask for
`RedrawWindow` after running the said function during `WM_PAINT`
handling.

Fixes #3150.

d06deeecf6 Make WindowBuilder Send + Sync
Window builder is always accessed by winit on the thread event loop
is on, thus it's safe to mark the data it gets as `Send + Sync`.
Each unsafe object is marked individually as `Send + Sync` instead
of just implementing `Send` and `Sync` for the whole builder.

f3fb27c17b Add a note on Window::request_redraw on Windows
Fixing this could require a massive rework to how redraw is handled
on windows to the point of removing `WM_PAINT`, since it's not reliable
by any means for our use case.

For now at least document that the API is broken. It was broken like
that for a long while.

7451c4b88c Android: Support unicode character mapping + dead keys
Up until now the Android backend has been directly mapping key codes
which essentially just represent the "physical" cap of the key (quoted
since this also related to virtual keyboards).

Since we didn't account for any meta keys either it meant the backend
only supported a 1:1 mapping from key codes, which only covers a tiny
subset of characters. For example you couldn't type a colon since
there's no keycode for that and we didn't try and map Shift+Semicolon
into a colon character.

This has been tricky to support because the `NativeActivity` class doesn't
have direct access to the Java `KeyEvent` object which exposes a more
convenient `getUnicodeChar` API.

It is now possible to query a `KeyCharcterMap` for the device associated
with a `KeyEvent` via the `AndroidApp::device_key_character_map` API
which provides a binding to the SDK `KeyCharacterMap` API in Java:

 https://developer.android.com/reference/android/view/KeyCharacterMap

This is effectively what `getUnicodeChar` is implemented based on and is
a bit more general purpose.

`KeyCharacterMap` lets us map a key_code + meta_state from a `KeyEvent`
into either a unicode character or dead key accent that can be combined
with the following key. This mapping is done based on the user's chosen
layout for the keyboard.

To enable support for key character maps the
`AndroidApp::input_events()` API was replaced by
`AndroidApp::input_events_iter()` which returns a (lending) iterator for
events. This was changed because the previous design made it difficult
to allow other AndroidApp APIs to be used while iterating events (mainly
because AndroidApp held a lock over the backend during iteration)

2791cbd65e Make with_x11_visual take ID instead of a pointer
At the moment, the with_x11_visual function takes a pointer and
immediately dereferences it to get the visual info inside. As it is safe
to pass a null pointer to this function, it is unsound. This commit
replaces the pointer parameter with a visual ID, and then uses that ID
to look up the actual visual under
the X11 setup. As this is what was already practically happening before,
this change shouldn't cause any performance downgrades.

This is a breaking change, but it's done in the name of soundness so it
should be okay. It should be trivial for end users to accommodate it,
as it's just a matter of getting the visual ID from the pointer to the
visual before passing it in.

3925281652 Remove RedrawEventsCleared + MainEventsCleared, and added AboutToWait
The idea that redraw events are dispatched with a specific ordering
that makes it possible to specifically report when we have finished
dispatching redraw events isn't portable and the way in which we
dispatched RedrawEventsCleared was inconsistent across backends.

More generally speaking, there is no inherent relationship between
redrawing and event loop iterations. An event loop may wake up at any
frequency depending on what sources of input events are being listened
to but redrawing is generally throttled and in some way synchronized
with the display frequency.

Similarly there's no inherent relationship between a single event loop
iteration and the dispatching of any specific kind of "main" event.

An event loop wakes up when there are events to read (e.g. input
events or responses from a display server / compositor) and goes back
to waiting when there's nothing else to read.

There isn't really a special kind of "main" event that is dispatched
in order with respect to other events.

What we can do more portably is emit an event when the event loop
is about to block and wait for new events.

In practice this is very similar to how MainEventsCleared was
implemented except it wasn't the very last event previously since
redraw events could be dispatched afterwards.

The main backend where we don't strictly know when we're going to
wait for events is Web (since the real event loop is internal to
the browser). For now we emulate AboutToWait on Web similar to how
MainEventsCleared was dispatched.

In practice most applications almost certainly shouldn't care about
AboutToWait because the frequency of event loop iterations is
essentially arbitrary and usually irrelevant.

07652c76fb window_ondemand: wait for Destroyed event before exiting app
Considering the strict requirement that applications can't keep windows
across run_ondemand calls, this tries to make the window_ondemand example
explicitly wait for its Window to be destroyed before exiting each
run_ondemand iteration.

This updates the example to only `.set_exit()` after it gets a
`Destroyed` event after the Window has been dropped.

On Windows this works to ensure the Window is destroyed before the
example waits for 5 seconds.

Unfortunately though:
1. The Wayland backend doesn't emit `Destroyed` events for windows
2. The macOS backend emits `Destroyed` events before the window is
   really destroyed.

and so the example isn't currently portable.

and starting the second loop.

e28974bc04 Re-work event loop run() API so it can return a Result
This re-works the portable `run()` API that consumes the `EventLoop` and
runs the loop on the calling thread until the app exits.

This can be supported across _all_ platforms and compared to the
previous `run() -> !` API is now able to return a `Result` status on all
platforms except iOS and Web. Fixes: #2709

By moving away from `run() -> !` we stop calling `std::process::exit()`
internally as a means to kill the process without returning which means
it's possible to return an exit status and applications can return from
their `main()` function normally.

This also fixes Android support where an Activity runs in a thread but
we can't assume to have full ownership of the process (other services
could be running in separate threads).

Additionally all examples have generally been updated so that `main()`
returns a `Result` from `run()`

a02c680a87 Linux: Implement EventLoopExtPumpEvents and EventLoopExtRunOnDemand
Wayland:

I found the calloop abstraction a little awkward to work with while I was
trying to understand why there was surprising workaround code in the wayland
backend for manually dispatching pending events.

Investigating this further it looks like there may currently be several issues
with the calloop WaylandSource (with how prepare_read is used and with (not)
flushing writes before polling)

Considering the current minimal needs for polling in all winit backends I do
personally tend to think it would be simpler to just own the responsibility for
polling more directly, so the logic for wayland-client `prepare_read` wouldn't
be in a separate crate (and in this current situation would also be easier to fix)

I've tried to maintain the status quo with calloop + workarounds.

X11:

I found that the recent changes (4ac2006cbc) to port the X11 backend
from mio to calloop lost the ability to check for pending events before
needing to poll/dispatch. (The `has_pending` state being queried
before dispatching() was based on state that was filled in during
dispatching)

As part of the rebase this re-introduces the PeekableReceiver and
WakeSender which are small utilities on top of
`std::sync::mpsc::channel()`. This adds a calloop `PingSource`
so we can use a `Ping` as a generic event loop waker.

For taking into account false positive wake ups the X11 source now
tracks when the file descriptor is readable so after we poll via
calloop we can then specifically check if there are new X11 events
or pending redraw/user events when deciding whether to skip the
event loop iteration.

6bb62d0b13 MacOS: Implement EventLoopExtPumpEvents and EventLoopExtRunOnDemand
The implementation of `pump_events` essentially works by hooking into the
`RunLoopObserver` and requesting that the app should be stopped the next time
that the `RunLoop` prepares to wait for new events.

Originally I had thought I would poke the `CFRunLoop` for the app directly and
I was originally going to implement `pump_events` based on a timeout which I'd
seen SDL doing.

I found that `[NSApp run]` wasn't actually being stopped by asking the RunLoop
to stop directly and inferred that `NSApp run` will actually catch this and
re-start the loop.

Hooking into the observer and calling `[NSApp stop]` actually seems like a
better solution that doesn't need a hacky constant timeout.

The end result is quite similar to what happens with existing apps that
call `run_return` inside an external loop and cause the loop to exit for
each iteration (that also results in the `NSApp` stopping each
iteration).

fae4cbd2aa Windows: Implement EventLoopExtPumpEvents and EventLoopExtRunOnDemand
A surprising amount of work was required to enable these extensions
on Windows.

I had originally assumed that pump_events was going to be very similar
to run except would use PeekMessageW instead of GetMessageW to avoid
blocking the external loop but I found the Windows backend broke
several assumptions I had.

Overall I think these changes can hopefully be considered a quite a
significant simplification (I think it's a net deletion of a fair amount
of code) and I think it also helps bring it into slightly closer alignment
with other backends too

Key changes:
- I have removed the `wait_thread` that was a fairly fiddly way of handling
  `ControlFlow::WaitUntil` timeouts in favor of using `SetTimer` which works
  with the same messages picked up by `GetMessage` and `PeekMessage`.
- I have removed the ordering guarantees between `MainEventsCleared`,
  `RedrawRequested` and `RedrawEventsCleared` events due to the complexity in
  maintaining this artificial ordering, which is already not supported
  consistently across backends anyway (in particular this ordering already
  isn't compatible with how MacOS / iOS work).
- `RedrawRequested` events are now directly dispatched via `WM_PAINT` messages
  - comparable to how `RedrawRequested` is dispatched via `drawRect` in the
  MacOS backend.
- I have re-worked how `NewEvents`, `MainEventsCleared`, and `RedrawEventsCleared`
  get dispatched to be more in line with the MacOS backend and also more in line
  with how we have recently discussed defining them for all platforms.

  `NewEvents` is conceptually delivered when the event loop "wakes up" and
  `MainEventsCleared` gets dispatched when the event loop is about to ask the
  OS to wait for new events.

  This is a more portable model, and is already how these events work in the
  MacOS backend.

  `RedrawEventsCleared` are just delivered after `MainEventsCleared` but this
  event no longer has a useful meaning.

Probably the most controversial thing here is that this "breaks" the ordering
rules for redraw event handling, but since my changes interacted with how the
order is maintained I was very reluctant to figure out how to continue
maintaining something that we have recently been discussing changing:

https://github.com/rust-windowing/winit/issues/2640.

Additionally, since the MacOS backend already doesn't strictly maintain this
order it's somewhat academic to see this as a breakage if Winit applications
can't really rely on it already.

This updates the documentation for `request_redraw()` to reflect that we
no longer guarantee that `RedrawRequested` events must be dispatched
after `MainEventsCleared`.

164dce2b8a Add EventLoopExtPumpEvents and EventLoopExtRunOnDemand
This adds two new extensions for running a Winit event loop which will
replace `EventLoopExtRunReturn`

The `run_return` API is trying to solve multiple problems and address
multiple, unrelated, use cases but in doing so it is not succeeding
at addressing any of them fully.

The notable use cases we have are:
1. Applications want to be able to implement their own external
   event loop and call some Winit API to poll / pump events, once
   per iteration of their own loop, without blocking the outer,
   external loop. Addressing #2706
2. Applications want to be able to re-run separate instantiations
   of some Winit-based GUI and want to allow the event loop to exit with
   a status, and then later be able to run the loop again for a new
   instantiation of their GUI. Addressing #2431

It's very notable that these use cases can't be supported across
all platforms and so they are extensions, similar to
`EventLoopExtRunReturn`

The intention is to support these extensions on:
- Windows
- Linux (X11 + Wayland)
- macOS
- Android

These extensions aren't compatible with Web or iOS though.

Each method of running the loop will behave consistently in terms of how
`NewEvents(Init)`, `Resumed` and `LoopDestroyed` events are dispatched
(so portable application code wouldn't necessarily need to have any awareness
of which method of running the loop was being used)

Once all backends have support for these extensions then we can
remove `EventLoopExtRunReturn`

For simplicity, the extensions are documented with the assumption that
the above platforms will be supported.

This patch makes no functional change, it only introduces these new
extensions so we can then handle adding platform-specific backends
in separate pull requests, so the work can be landed in stages.

* Prepare `init` methods for not having access to &mut self

* Prepare WinitWindow methods for not having access to &mut self

* Convert a bit of WinitView's to use interior mutability

* Convert a bit more of WinitView's to use interior mutability

* Convert the rest of WinitView to use interior mutability

* Use interior mutability instead of a Mutex for the CursorState

* Use interior mutability in WinitWindowDelegate

# Contribution Guidelines
# Winit Contributing Guidelines
This document contains guidelines for contributing code to winit. It has to be
followed in order for your patch to be approved and applied.
## 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.
## Contributing
Anyone can contribute to winit, however given that it's a cross platform
windowing toolkit getting certain changes incorporated could be challenging.
## Reporting an issue
To save your time it's wise to check already opened [pull requests][prs] and
[issues][issues]. In general, bug fixes and missing implementations are always
accepted, however larger new API proposals should go into the issue first. When
in doubt contact us on [Matrix][matrix] or via opening 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:
### Windows
- if it is a bug, please provide 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
To run the examples on Windows, you must have symlinks enabled, see
[this][git-windows-symlinks].
## Making a pull request
[git-windows-symlinks]: https://gitforwindows.org/symbolic-links.html
When making a code contribution to winit, before opening your pull request, please make sure that:
### Submitting your work and handling review
- your patch builds with Winit's minimal supported rust version - Rust 1.65.
- 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.
All patches have to be sent on Github as [pull requests][prs]. To simplify your
life during review it's recommended to check the "give contributors write access
to the branch" checkbox.
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.
We use unstable Rustfmt options across the project, so please run
`cargo +nightly fmt` before submitting your work. If you are unable to do so,
the maintainers can do it for you before merging, just state so in your pull
request description. For details on how to use nightly, consult [the
documentation][toolchains].
Once your PR is open, you can ask for 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).
When editing markdown files (`.md`) they must be wrapped at 80 characters.
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.
[toolchains]: https://rust-lang.github.io/rustup/concepts/toolchains.html
## Maintainers & Testers
#### Handling review
The current maintainers are listed in the [CODEOWNERS](.github/CODEOWNERS) file.
During the review process certain events could require an action from your side,
common patterns and reactions are described below.
If you are interested in being pinged when testing is needed for a certain platform, please add yourself to the [Testers and Contributors](https://github.com/rust-windowing/winit/wiki/Testers-and-Contributors) table!
_Event:_ The CI fails to build, but it looks like it is not your fault. Not
communicating so could result in maintainers not looking into your patch,
since they may assume that you're still working on it.\
_Desired behaviour:_ Write a message saying roughly the following "The CI
failure is unrelated", so that the maintainers will fix it for you.
## Release process
_Event:_ Maintainer requested changes to your PR.\
_Desired behavior:_ Once you address the request, you should re-request a review
with GitHub's UI. If you don't agree with what maintainer suggested, you
should state your objections and re-request the review. That will indicate that
the ball is on maintainer's side.
_Event:_ You've opened a PR, but maintainer shortly after commented that they
want to work on that themselves.\
_Desired behavior:_ Discuss with the maintainer regarding their plans if they
were not outlined in the initial response, because such response means that they
are not interested in reviewing your code. Such thing could happen when
underestimating complexity of the task you're solving or when your patch
mandate certain downstream designs. In general, the maintainer will likely
close your PR in order to prevent work being done on it.

[issues]: https://github.com/rust-windowing/winit/issues
[matrix]: https://matrix.to/#/#rust-windowing:matrix.org
## Maintainers
Winit has plenty of maintainers with different backgrounds, different time
available to work on Winit, and reasons to be winit maintainer in the first
place. To ensure that Winit's code quality does not decrease over time and to
make it easier to teach new maintainers the "winit way of doing things" the
common policies and routines are defined in this section.
The current maintainers for each platform are listed in [this file][CODEOWNERS].
### Contributions handling
The maintainers must ensure that the external contributions meet Winit's
quality standards. If it's not, it **is the maintainer's responsibility** to
bring it on par, which includes:
- Ensure that formatting is consistent and `CHANGELOG` messages are clear
for the end users.
- Improve the commit message, so it'll be easier for other maintainers to
understand the motivation without going through all the discussions on the
particular patch/PR.
- Ensure that the proposed patch doesn't break platform parity. If the
breakage is desired by contributor, an issue should be opened to discuss
with other maintainers before merging.
- Always fix CI issues before merging if they don't originate from the
submitted work.
However, maintainers should give some leeway for external contributors, so they
don't feel discouraged contributing, for example:
- Suggest a patch to resolve style issues, if it's the only issue with the
submitted work. Keep in mind that pushing the resolution yourself is not
desired, because the contributor might not agree with what you did.
- Be more explicit on how things should be done if you don't like the
approach.
- Suggest to finish the PR for them if they're absent for a while and you need
the proposed changes to move forward with something. In such cases the
maintainer must preserve attribution with `Co-authored-by`, `Suggested-by`,
or keep the original committer.
- Rebase their work for them when massive changes to the Winit codebase were
introduced.
When reviewing code of other maintainers all of the above is on the maintainer
who submitted the patch. Interested maintainers could help push the work over
the finish line, but teaching other maintainers should be preferred.
For a _regular_ contributor to winit, the maintainer should slowly start
requiring contributor to match *maintainer* quality standards when writing
patches and commit messages.
### Contributing
When submitting a patch, the maintainer should follow the general contributing
guidelines, however greater attention to detail is expected in this case.
To make life simpler for other maintainers it's suggested to create your branch
under the project repository instead of your own fork. The naming scheme is
`github_user_name/branch_name`. Doing so will make your work easier to rebase
for other maintainers when you're absent.
### Administrative Actions
Some things (such as changing required CI steps, adding contributors, ...)
require administrative permissions. If you don't have those, ask about the
change in an issue. If you have the permissions, discuss it with at least one
other admin before making the change.
### Release process
Given that winit is a widely used library, we should be able to make a patch
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`
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. Update released `cfg_attr` in `src/changelog/mod.rs` to `v0.2.md`
4. Move entries from `src/changelog/unreleased.md` into
`src/changelog/v0.2.md`
5. In the branch, the version is bumped to `v0.2.0`
6. The new commit in the branch is tagged `v0.2.0`
7. The version is pushed to crates.io
8. A GitHub release is created for the `v0.2.0` tag
9. 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`
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 4-9 of the regular release example
[CODEOWNERS]: .github/CODEOWNERS
4. Follow steps 3-7 of the regular release example

## 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 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.

## 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 the window.
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.
## CONTRIBUTING
### Cargo Features
For contributing guidelines see [CONTRIBUTING.md](./CONTRIBUTING.md).
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.

### Platform-specific usage
Check out the [`winit::platform`](https://docs.rs/winit/latest/winit/platform/index.html) module for platform-specific usage.
#### Wayland
### Repository License
Note that windows don't appear on Wayland until you draw/present to them.
Note that the license in `LICENSE` doesn't apply in full to the DPI package [./dpi](./dpi).
Full details can be found in that folder's README.
<!-- This doesn't apply to users of the Winit crate, but this is also the repository level README -->
#### WebAssembly
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 example code using Winit with WebAssembly, check out the [web example]. For
information on using Rust on WebAssembly, check out the [Rust and WebAssembly
book].

[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 entrypoint. 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`] which is 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/rib/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 = "0.29.3", 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]. You should consider creating your windows
inside `Event::Resumed`.

its orbital display server provides it.

# 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
## 0.1.2
- Added `Insets`, `LogicalInsets` and `PhysicalInsets` types.
- Make `no_std` compatible. If you use this functionality, DPI's license has changed.
## 0.1.1
- Derive `Debug`, `Copy`, `Clone`, `PartialEq`, `Serialize`, `Deserialize` traits for `PixelUnit`.
## 0.1.0
- Add `LogicalUnit`, `PhysicalUnit` and `PixelUnit` types and related functions.

# DPI
Full docs can be found on docs.rs.
## License
Most of DPI is licensed under the Apache License, Version 2.0 ([LICENSE](LICENSE)).
All files except for `src/libm.rs` (and `LICENSE-LIBM-MIT`) are available solely under that license.
For its `no_std` support, DPI uses code from the [libm](https://crates.io/crates/libm) crate.
This is in the `libm.rs` file, and is licensed solely under the MIT Licence ([LICENSE-LIBM-MIT](LICENSE-LIBM-MIT)).
That file contains details of all potentially applicable copyright notices.
This is feature gated to only be included if you disable the `std` feature, otherwise it will not be compiled into your final binary
(and so these license terms will not apply).
Overall, this means that the license for this crate depends on what features you have enabled.
If you enable the `std` feature, then DPI uses only code available under the Apache-2.0 license, and so can be used under the terms of that license.
However, if you disable the `std` feature, then both these licenses must be followed to use the crate as a whole.

When using so called 'natural scrolling' (scrolling that acts like on a touch screen), this is what to expect:
Moving your finger downwards on a scroll wheel should make the window move down, and you should see a positive Y scroll value.
When moving fingers on a trackpad down and to the right, you should see positive X and Y deltas, and the window should move down and to the right.
With reverse scrolling, you should see the inverse behavior.
In both cases the example window should move like the content of a scroll area in any other application.
In other words, the deltas indicate the direction in which to move the content (in this case the window)."

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

//! Winit is a cross-platform window creation and event loop management library.
//!
//! # Building windows
//!
//! Before you can build a [`Window`], you first need to build an [`EventLoop`]. This is done with the
//! [`EventLoop::new()`] function.
//!
//! ```no_run
//! use winit::event_loop::EventLoop;
//! let event_loop = EventLoop::new().unwrap();
//! ```
//!
//! Once this is done there are two ways to create a [`Window`]:
//!
//! - Calling [`Window::new(&event_loop)`][window_new].
//! - Calling [`let builder = WindowBuilder::new()`][window_builder_new] then [`builder.build(&event_loop)`][window_builder_build].
//!
//! The first method is the simplest, and will give you default values for everything. The second
//! method 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`].
//!
//! # Event handling
//!
//! Once a [`Window`] has been created, it will generate different *events*. A [`Window`] object can
//! generate [`WindowEvent`]s when certain input events occur, such as a cursor moving over the
//! window or a key getting pressed while the window is focused. Devices can generate
//! [`DeviceEvent`]s, which contain unfiltered event data that isn't specific to a certain window.
//! Some user activity, like mouse movement, can generate both a [`WindowEvent`] *and* a
//! [`DeviceEvent`]. You can also create and handle your own custom [`Event::UserEvent`]s, if desired.
//!
//! You can retrieve events by calling [`EventLoop::run()`]. This function will
//! dispatch events for every [`Window`] that was created with that particular [`EventLoop`], and
//! will run until [`exit()`] is used, at which point [`Event::LoopExiting`].
//!
//! Winit no longer uses a `EventLoop::poll_events() -> impl Iterator<Event>`-based event loop
//! model, since that can't be implemented properly on some platforms (e.g web, iOS) and works poorly on
//! most other platforms. However, this model can be re-implemented to an extent with
#![cfg_attr(
any(
windows_platform,

//! [^1]. See that method's documentation for more reasons about why
//! it's discouraged, beyond compatibility reasons.
//!
//!

//! use winit::{
//! event::{Event, WindowEvent},
//! event_loop::{ControlFlow, EventLoop},
//! window::WindowBuilder,
//! };
//!
//! let event_loop = EventLoop::new().unwrap();
//! let window = WindowBuilder::new().build(&event_loop).unwrap();
//!
//! // ControlFlow::Poll continuously runs the event loop, even if the OS hasn't
//! // dispatched any events. This is ideal for games and similar applications.
//! event_loop.set_control_flow(ControlFlow::Poll);
//!
//! // ControlFlow::Wait pauses the event loop if no events are available to process.
//! // This is ideal for non-game applications that only update in response to user
//! // input, and uses significantly less power/CPU time than ControlFlow::Poll.
//! event_loop.set_control_flow(ControlFlow::Wait);
//!
//! event_loop.run(move |event, elwt| {
//! match event {
//! Event::WindowEvent {
//! event: WindowEvent::CloseRequested,
//! ..
//! } => {
//! println!("The close button was pressed; stopping");
//! elwt.exit();
//! },
//! Event::AboutToWait => {
//! // Application update code.
//!
//! // Queue a RedrawRequested event.
//! //
//! // You only need to call this if you've determined that you need to redraw, in
//! // applications which do not always need to. Applications that redraw continuously
//! // can just render here instead.
//! window.request_redraw();
//! },
//! Event::WindowEvent {
//! event: WindowEvent::RedrawRequested,
//! ..
//! } => {
//! // Redraw the application.
//! //
//! // It's preferable for applications that do not render continuously to render in
//! // this event rather than in AboutToWait, since rendering in here allows
//! // the program to gracefully handle redraws requested by the OS.
//! },
//! _ => ()
//! }
//! });
//! ```
//!
//! [`WindowEvent`] has a [`WindowId`] member. In multi-window environments, it should be
//! compared to the value returned by [`Window::id()`] to determine which [`Window`]
//! dispatched the event.
//!
//! # Drawing on the window
//!
//! Winit doesn't directly provide any methods for drawing on a [`Window`]. However it allows you to
//! retrieve the raw handle of the window and display (see the [`platform`] module and/or the
//! [`raw_window_handle`] and [`raw_display_handle`] methods), which in turn allows
//! you to create an OpenGL/Vulkan/DirectX/Metal/etc. context that can be used to render graphics.
//!
//! Note that many platforms will display garbage data in the window's client area if the
//! application doesn't render anything to the window by the time the desktop compositor is ready to
//! display the window to the user. If you notice this happening, you should create the window with
//! [`visible` set to `false`](crate::window::WindowBuilder::with_visible) and explicitly make the
//! window visible only once you're ready to render into it.

/// ```
///
/// **Note:** This is not a portable API, and its usage involves a number of
/// caveats and trade offs that should be considered before using this API!
///
/// You almost certainly shouldn't use this API, unless you absolutely know it's
/// the only practical option you have.
///
/// ## Synchronous events
///
/// Some events _must_ only be handled synchronously via the closure that
/// is passed to Winit so that the handler will also be synchronized with
/// the window system and operating system.
///
/// This is because some events are driven by a window system callback
/// where the window systems expects the application to have handled the
/// event before returning.
///
/// **These events can not be buffered and handled outside of the closure
/// passed to Winit.**
///
/// As a general rule it is not recommended to ever buffer events to handle
/// them outside of the closure passed to Winit since it's difficult to
/// provide guarantees about which events are safe to buffer across all
/// operating systems.
///
/// Notable events that will certainly create portability problems if
/// buffered and handled outside of Winit include:
/// - `RedrawRequested` events, used to schedule rendering.
///
/// macOS for example uses a `drawRect` callback to drive rendering
/// within applications and expects rendering to be finished before
/// the `drawRect` callback returns.
///
/// For portability it's strongly recommended that applications should
/// keep their rendering inside the closure provided to Winit.
/// - Any lifecycle events, such as `Suspended` / `Resumed`.
///
/// The handling of these events needs to be synchronized with the
/// operating system and it would never be appropriate to buffer a
/// notification that your application has been suspended or resumed and
/// then handled that later since there would always be a chance that
/// other lifecycle events occur while the event is buffered.
///
/// ## Supported Platforms
/// - Windows
/// - Linux
/// - MacOS
/// - Android
///
/// ## Unsupported Platforms
/// - **Web:** This API is fundamentally incompatible with the event-based way in which
/// Web browsers work because it's not possible to have a long-running external
/// loop that would block the browser and there is nothing that can be
/// polled to ask for new new events. Events are delivered via callbacks based
/// on an event loop that is internal to the browser itself.
/// - **iOS:** It's not possible to stop and start an `NSApplication` repeatedly on iOS so
/// there's no way to support the same approach to polling as on MacOS.
///
/// ## Platform-specific
/// - **Windows**: The implementation will use `PeekMessage` when checking for
/// window messages to avoid blocking your external event loop.
///
/// - **MacOS**: The implementation works in terms of stopping the global `NSApp`
/// whenever the application `RunLoop` indicates that it is preparing to block
/// and wait for new events.
///
/// This is very different to the polling APIs that are available on other
/// platforms (the lower level polling primitives on MacOS are private
/// implementation details for `NSApp` which aren't accessible to application
/// developers)
///
/// It's likely this will be less efficient than polling on other OSs and
/// it also means the `NSApp` is stopped while outside of the Winit
/// event loop - and that's observable (for example to crates like `rfd`)
/// because the `NSApp` is global state.
///
/// If you render outside of Winit you are likely to see window resizing artifacts
/// since MacOS expects applications to render synchronously during any `drawRect`
/// callback.
