2dae807c4f On X11, filter out tiny device mouse events
Usually, if mouse events are equal to (0, 0) we filter them out.
However, if the event is very close to zero it will still be given to
the user. In some cases this can be caused by bad float math on the X11
server side.

Fix it by filtering absolute values smaller than floating point epsilon.

016fd47d0d On X11, force resend modifiers when focus changes
Given that `ModifiersChanged` is a window event, it means that clients
may track it for each window individually, thus not sending it between
focus changes may result in modifiers getting desynced on the consumer
side.

cb855b87cc On X11, use events modifiers to detect state
While there's a separate event to deliver modifiers for keyboard,
unfortunately, it's not even remotely reflects the modifiers state.

Thus use events along side regular modifier updates to correctly
detect the state. Also, apply the modifiers from the regular
key event by converting their state to xkb modifiers state.

bd2d2760f0 On Windows, apply ScaleFactorChanged new size if different than OS
This fixes an issue when setting the position of the window on a new
monitor and immediately maximizing it

```rs
window.set_outer_position::<PhysicalPosition<u32>>((2000, 200).into());
window.set_maximized(true);
```

Due to the nature of the event loop, the requested position and
maximization state will apply correctly but due to the fact that the new
position is a different monitor, a `ScaleFactorChanged` is emitted
afterwards to the evenloop and a new size is set while the window is
still maximized which results in a window that has `WS_MAXIMZE` window
style but doesn't cover the whole monitor.

c9030f06c0 On Wayland, send Focused(false) once seats left
Given that we merge all the seats, we should consider that window
is not focused once all seats wl_keyboards are no longer present.

We use seats instead of keyboards to track focus to protect against
wl_keyboard::leave not being delivered when removing the seat
(usually it's not the case though).

57cb3126d6 On Wayland, disable Occluded handling
Change in state requires a redraw, however drawing when getting
`Occluded` with vsync will block indefinitely, thus the event in
it's current state is rather useless.

To solve this issue winit needs a way to determine whether the user
paused/continued their render loop, so it can commit on their behalf.

This commit also forces redraw when getting configure.

221b2e71cd bugfix: Fix swapped instance and general class names on X11
This let statement swapped the two names, resulting in incorrect
behavior since commit d7ec899d. That commit did not actually introduce
the swap, but the previous code swapped it again before setting the
WM_CLASS property, so no issue was ever observed.

It also brings the documentation in line with the implementation since the
parent commit, and with the ICCCM standard, which states the following
about the WM_CLASS property [1]:

  The two strings, respectively, are:
  * A string that names the particular instance of the application [...]
  * A string that names the general class of applications [...]

5b4f97edac On X11, query for higher Xrandr version
This appears to be the solution for the elusive #3335 issue. Previously,
in the Xlib backend, we used the "XRRQueryVersion" function to query for
the Xrandr version, and used that to determine whether we should use the
"GetScreenResources" call or the "GetScreenResourcesCurrent" call.

However, we passed the version "0, 0" into "XRRQueryVersion".
Previously with Xlib this wasn't a problem, as Xlib ignores the version
you pass in and substitutes it with the version of RandR it expects.

https://gitlab.freedesktop.org/xorg/lib/libxrandr/-/blob/master/src/Xrandr.c?ref_type=heads#L386-387

The way that "XRRQueryVersion" is implemented on the server end, it
compares the version passed into the request with the version supported
by the server. If the server's version is greater than the client
version, it just returns the client version. If the client's version is
greater, it passes the server's version. Since we were passing in "0, 0"
this means that the server returned "0, 0".

https://gitlab.freedesktop.org/xorg/xserver/-/blob/master/randr/rrdispatch.c?ref_type=heads#L50-59

To determine whether we use "GetScreenResources" or
"GetScreenResourcesCurrent", we compare the version returned by the
server against "1, 3". Since we got "0, 0"- a version of XRandR so old
it doesn't even exist- we use "GetScreenResources".

The problem manifests in that "GetScreenResources" can take several
seconds to query the screen state based on the current hardware
configuration. On the other hand, "GetScreenResourcesCurrent" is fast;
it uses the server's hardware cache if it is available.

This problem is visible in XTrace. On the latest `master`:

```
000:<:00c2: 12: RANDR-Request(140,0): QueryVersion major-version=0 minor-version=0
000:>:00c2:32: Reply to QueryVersion: major-version=0 minor-version=0
000:<:00c3:  8: RANDR-Request(140,8): GetScreenResources window=0x0000076e
000:>:00c3:1600: Reply to GetScreenResources:
```

On the `v0.28.0` tag:

```
000:<:0019: 12: RANDR-Request(140,0): QueryVersion major-version=1 minor-version=6
000:>:0019:32: Reply to QueryVersion: major-version=1 minor-version=6
...later
000:<:002d:  8: RANDR-Request(140,25): GetScreenResourcesCurrent window=0x0000076e
000:>:002d:1600: Reply to GetScreenResourcesCurrent
```

This commit fixes this issue by requesting "1, 3" instead. This returns
the version we expect, where we can now use "GetScreenResourcesCurrent"
properly.

Fixes #3335

5011a67f6d m: Update to x11rb 0.13.0
The only breaking change is that x11rb no longer reports an error when
querying the WmSizeHints of a window that does not have this property
set. For this reason, the return type of WmSizeHintsCookie::Reply()
changed from Result<WmSizeHints, SomeError> to
Result<Option<WmSizeHints>, SomeError>.

In update_normal_hints(), previously a cryptic error would be reported
to the caller. Instead, this now uses unwrap_or_default() to get a
WmSizeHints. All fields of WmSizeHints are Options, so this produces an
empty object.

resize_increments() queries a value from the window and returns an
Option. Previously, the error for "missing property" was turned into
None via .ok(). This commit adds a call to flatten() to also turn
"property not set" into None.

Finally, request_user_attention() queries a window's WmHints property
and updates one field of it. The code already uses unwrap_or_default()
to deal with missing properties, so just a call to flatten() is needed
to merge "missing property" and "error while querying" into one.

Other changes in x11rb do not seem to affect this crate.

x11rb's MSRV increased from 1.56 to 1.63, which is still below the MSRV
of this crate, which is 1.65.

a97309690e On Wayland, fix wl_surface being dropped first
The surface was automatically dropped due to new RAII type in SCTK
when dropping the Window, which was not the case at some point with
SCTK.

Thus destroying objects associated with it where causing issues
with some window managers.

7103514ae8 Disable default-features for the ndk crate
We decided to add `rwh_06` to the `default` list of features in the
`ndk` to [nudge users to upgrade], but this forces `winit` to always
(transitively) include `raw-window-handle 0.6` even if the user has
set a different `rwh_xx` feature on the `winit` crate.  `winit` already
forwards the respective `rwh_xx` feaure to the `ndk` crate anyway, so
this default should just be turned off.

At the time of writing this is the only `default` feature of the `ndk`.

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.

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.

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.

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.

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.

d83188befd Rename Window::set_inner_size to Window::request_inner_size
Some systems could resize the window immediately and we'd rather
inform the users right away if that was the case, so they could
create e.g. EGLSurface without waiting for resize, which is really
important for Wayland.

Fixes #2868.

7a4ce631bd On X11, avoid false positive key repeats
Instead of a single `bool` indicating that a key press has occured and
no key has been released since then, we store the scancode of the last
pressed key (if it is a key that repeats when held). This fixes a bug
where pressing a new key while one is already held down will be flagged
as a repeat even though it is obviously not a repeat.

8d5f82f0c0 Stop using &mut in Objective-C delegate methods (#2925)
* Make iOS declared classes not use &mut

* 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:
### Submitting your work and handling review
- 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
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.
## Making a pull request
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].
When making a code contribution to winit, before opening your pull request, please make sure that:
When editing markdown files (`.md`) they must be wrapped at 80 characters.
- 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.
[toolchains]: https://rust-lang.github.io/rustup/concepts/toolchains.html
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.
#### Handling review
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).
During the review process certain events could require an action from your side,
common patterns and reactions are described below.
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.
_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.
## Maintainers & Testers
_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.
The current maintainers are listed in the [CODEOWNERS](.github/CODEOWNERS) file.
_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.
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!
[prs]: https://github.com/rust-windowing/winit/pulls
[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
## 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.
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. 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
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

# 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 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.

### 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 the 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 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 = "0.29.13", 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`.

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

/// On iOS, the [`resumed()`] method is called in response to an [`applicationDidBecomeActive`]
/// callback which means the application is about to transition from the inactive to active
/// state (according to the [iOS application lifecycle]).

///
/// ### Web
///
/// On Web, the [`resumed()`] method is called in response to a [`pageshow`] event if the
/// page is being restored from the [`bfcache`] (back/forward cache) - an in-memory cache

/// ### Android
///
/// On Android, the [`resumed()`] method is called when the `Activity` is (again, if after a
/// prior [`suspended()`]) being displayed to the user. This is a good place to begin drawing
/// visual elements, running animations, etc. It is driven by Android's [`onStart()`] method.

/// Emitted from the point onwards the application should create render surfaces.
///
/// See [`destroy_surfaces()`].
///
/// ## Portability
///
/// It's recommended that applications should only initialize their render surfaces after the
/// [`can_create_surfaces()`] method is called. Some systems (specifically Android) won't allow
/// applications to create a render surface until that point.
///
/// For consistency, all platforms call this method even if they don't themselves have a formal
/// surface destroy/create lifecycle. For systems without a surface destroy/create lifecycle the
/// [`can_create_surfaces()`] event is always emitted after the [`StartCause::Init`] event.
///
/// Applications should be able to gracefully handle back-to-back [`can_create_surfaces()`] and
/// [`destroy_surfaces()`] calls.
///
/// ## Platform-specific
///
/// ### Android
///
/// On Android, the [`can_create_surfaces()`] method is called when a new [`NativeWindow`]
/// (native [`Surface`]) is created which backs the application window. This is expected to
/// closely correlate with the [`onStart`] lifecycle event which typically results in a surface
/// to be created after the app becomes visible.
///
/// Applications that need to run on Android must wait until they have received a surface before
/// they will be able to create a render surface (such as an `EGLSurface`, [`VkSurfaceKHR`]
/// or [`wgpu::Surface`]) which depend on having a [`NativeWindow`]. Applications must handle
/// [`destroy_surfaces()`], where their render surfaces are invalid and should be dropped.

/// spuriously. For these reasons, you should not rely on the number of times that this was
/// called.
///
/// The order in which this is emitted in relation to other events is not guaranteed. The time

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
The sections should follow the order `Added`, `Changed`, `Deprecated`,
`Removed`, and `Fixed`.
Platform specific changed should be added to the end of the section and grouped
by platform name. Common API additions should have `, implemented` at the end
for platforms where the API was initially implemented. See the following example
on how to add them:
```md
### Added
- Add `Window::turbo()`, implemented on X11, Wayland, and Web.
- On X11, add `Window::some_rare_api`.
- On X11, add `Window::even_more_rare_api`.
- On Wayland, add `Window::common_api`.
- On Windows, add `Window::some_rare_api`.
```
When the change requires non-trivial amount of work for users to comply
with it, the migration guide should be added below the entry, like:
```md
- Deprecate `Window` creation outside of `EventLoop::run`
This was done to simply migration in the future. Consider the
following code:
// Code snippet.
To migrate it we should do X, Y, and then Z, for example:
// Code snippet.
```
The migration guide could reference other migration examples in the current
changelog entry.
## Unreleased
### Added
- Add `ActiveEventLoop::create_proxy()`.
- On Web, add `ActiveEventLoopExtWeb::is_cursor_lock_raw()` to determine if
`DeviceEvent::MouseMotion` is returning raw data, not OS accelerated, when using
`CursorGrabMode::Locked`.
- On Web, implement `MonitorHandle` and `VideoModeHandle`.
Without prompting the user for permission, only the current monitor is returned. But when
prompting and being granted permission through
`ActiveEventLoop::request_detailed_monitor_permission()`, access to all monitors and their
details is available. Handles created with "detailed monitor permissions" can be used in
`Window::set_fullscreen()` as well.
Keep in mind that handles do not auto-upgrade after permissions are granted and have to be
re-created to make full use of this feature.
- Implement `Clone`, `Copy`, `Debug`, `Deserialize`, `Eq`, `Hash`, `Ord`, `PartialEq`, `PartialOrd`
and `Serialize` on many types.
- Add `MonitorHandle::current_video_mode()`.
- Add `ApplicationHandlerExtMacOS` trait, and a `macos_handler` method to `ApplicationHandler` which returns a `dyn ApplicationHandlerExtMacOS` which allows for macOS specific extensions to winit.
- Add a `standard_key_binding` method to the `ApplicationHandlerExtMacOS` trait. This allows handling of standard keybindings such as "go to end of line" on macOS.
- On macOS, add `WindowExtMacOS::set_unified_titlebar` and `WindowAttributesExtMacOS::with_unified_titlebar`
to use a larger style of titlebar.
- Add `WindowId::into_raw()` and `from_raw()`.
- Add `PointerKind`, `PointerSource`, `ButtonSource`, `FingerId`, `primary` and `position` to all
pointer events as part of the pointer event overhaul.
- Add `DeviceId::into_raw()` and `from_raw()`.
- Added `Window::surface_position`, which is the position of the surface inside the window.
- Added `Window::safe_area`, which describes the area of the surface that is unobstructed.
- On X11, Wayland, Windows and macOS, improved scancode conversions for more obscure key codes.
- Add ability to make non-activating window on macOS using `NSPanel` with `NSWindowStyleMask::NonactivatingPanel`.
- Implement `MonitorHandleProvider` for `MonitorHandle` to access common monitor API.
- On X11, set an "area" attribute on XIM input connection to convey the cursor area.
- Implement `CustomCursorProvider` for `CustomCursor` to access cursor API.
- Add `CustomCursorSource::Url`, `CustomCursorSource::from_animation`.
- Implement `CustomIconProvider` for `RgbaIcon`.
- Add `icon` module that exposes winit's icon API.
### Changed
- Change `ActiveEventLoop` and `Window` to be traits, and added `cast_ref`/`cast_mut`/`cast`
methods to extract the backend type from those.
- `ActiveEventLoop::create_window` now returns `Box<dyn Window>`.
- `ApplicationHandler` now uses `dyn ActiveEventLoop`.
- On Web, let events wake up event loop immediately when using `ControlFlow::Poll`.
- Bump MSRV from `1.70` to `1.73`.
- Changed `ApplicationHandler::user_event` to `user_wake_up`, removing the
generic user event.
Winit will now only indicate that wake up happened, you will have to pair
this with an external mechanism like `std::sync::mpsc::channel` if you want
to send specific data to be processed on the main thread.
- Changed `EventLoopProxy::send_event` to `EventLoopProxy::wake_up`, it now
only wakes up the loop.
- On X11, implement smooth resizing through the sync extension API.
- `ApplicationHandler::can_create|destroy_surfaces()` was split off from
`ApplicationHandler::resumed/suspended()`.
`ApplicationHandler::can_create_surfaces()` should, for portability reasons
to Android, be the only place to create render surfaces.
`ApplicationHandler::resumed/suspended()` are now only emitted by iOS, Web
and Android, and now signify actually resuming/suspending the application.
- Rename `platform::web::*ExtWebSys` to `*ExtWeb`.
- Change signature of `EventLoop::run_app`, `EventLoopExtPumpEvents::pump_app_events` and
`EventLoopExtRunOnDemand::run_app_on_demand` to accept a `impl ApplicationHandler` directly,
instead of requiring a `&mut` reference to it.
- On Web, `Window::canvas()` now returns a reference.
- On Web, `CursorGrabMode::Locked` now lets `DeviceEvent::MouseMotion` return raw data, not OS
accelerated, if the browser supports it.
- `(Active)EventLoop::create_custom_cursor()` now returns a `Result<CustomCursor, ExternalError>`.
- Changed how `ModifiersState` is serialized by Serde.
- `VideoModeHandle::refresh_rate_millihertz()` and `bit_depth()` now return a `Option<NonZero*>`.
- `MonitorHandle::position()` now returns an `Option`.
- On macOS, remove custom application delegates. You are now allowed to override the
application delegate yourself.
- On X11, remove our dependency on libXcursor. (#3749)
- Renamed the following APIs to make it clearer that the sizes apply to the underlying surface:
- `WindowEvent::Resized` to `SurfaceResized`.
- `InnerSizeWriter` to `SurfaceSizeWriter`.
- `WindowAttributes.inner_size` to `surface_size`.
- `WindowAttributes.min_inner_size` to `min_surface_size`.
- `WindowAttributes.max_inner_size` to `max_surface_size`.
- `WindowAttributes.resize_increments` to `surface_resize_increments`.
- `WindowAttributes::with_inner_size` to `with_surface_size`.
- `WindowAttributes::with_min_inner_size` to `with_min_surface_size`.
- `WindowAttributes::with_max_inner_size` to `with_max_surface_size`.
- `WindowAttributes::with_resize_increments` to `with_surface_resize_increments`.
- `Window::inner_size` to `surface_size`.
- `Window::request_inner_size` to `request_surface_size`.
- `Window::set_min_inner_size` to `set_min_surface_size`.
- `Window::set_max_inner_size` to `set_max_surface_size`.
To migrate, you can probably just replace all instances of `inner_size` with `surface_size` in your codebase.
- Every event carrying a `DeviceId` now uses `Option<DeviceId>` instead. A `None` value signifies that the
device can't be uniquely identified.
- Pointer `WindowEvent`s were overhauled. The new events can handle any type of pointer, serving as
a single pointer input source. Now your application can handle any pointer type without having to
explicitly handle e.g. `Touch`:
- Rename `CursorMoved` to `PointerMoved`.
- Rename `CursorEntered` to `PointerEntered`.
- Rename `CursorLeft` to `PointerLeft`.
- Rename `MouseInput` to `PointerButton`.
- Add `primary` to every `PointerEvent` as a way to identify discard non-primary pointers in a
multi-touch interaction.
- Add `position` to every `PointerEvent`.
- `PointerMoved` is **not sent** after `PointerEntered` anymore.
- Remove `Touch`, which is folded into the `Pointer*` events.
- New `PointerKind` added to `PointerEntered` and `PointerLeft`, signifying which pointer type is
the source of this event.
- New `PointerSource` added to `PointerMoved`, similar to `PointerKind` but holding additional
data.
- New `ButtonSource` added to `PointerButton`, similar to `PointerKind` but holding pointer type
specific buttons. Use `ButtonSource::mouse_button()` to easily normalize any pointer button
type to a generic mouse button.
- New `FingerId` added to `PointerKind::Touch` and `PointerSource::Touch` able to uniquely
identify a finger in a multi-touch interaction. Replaces the old `Touch::id`.
- In the same spirit rename `DeviceEvent::MouseMotion` to `PointerMotion`.
- Remove `Force::Calibrated::altitude_angle`.
- On X11, use bottom-right corner for IME hotspot in `Window::set_ime_cursor_area`.
- On macOS and iOS, no longer emit `ScaleFactorChanged` upon window creation.
- On macOS, no longer emit `Focused` upon window creation.
- On iOS, emit more events immediately, instead of queuing them.
- Update `smol_str` to version `0.3`
- Rename `VideoModeHandle` to `VideoMode`, now it only stores plain data.
- Make `Fullscreen::Exclusive` contain `(MonitorHandle, VideoMode)`.
- Reworked the file drag-and-drop API.
The `WindowEvent::DroppedFile`, `WindowEvent::HoveredFile` and `WindowEvent::HoveredFileCancelled`
events have been removed, and replaced with `WindowEvent::DragEntered`, `WindowEvent::DragMoved`,
`WindowEvent::DragDropped` and `WindowEvent::DragLeft`.
The old drag-and-drop events were emitted once per file. This occurred when files were *first*
hovered over the window, dropped, or left the window. The new drag-and-drop events are emitted
once per set of files dragged, and include a list of all dragged files. They also include the
pointer position.
The rough correspondence is:
- `WindowEvent::HoveredFile` -> `WindowEvent::DragEntered`
- `WindowEvent::DroppedFile` -> `WindowEvent::DragDropped`
- `WindowEvent::HoveredFileCancelled` -> `WindowEvent::DragLeft`
The `WindowEvent::DragMoved` event is entirely new, and is emitted whenever the pointer moves
whilst files are being dragged over the window. It doesn't contain any file paths, just the
pointer position.
- Updated `objc2` to `v0.6`.
- Updated `windows-sys` to `v0.59`.
- To match the corresponding changes in `windows-sys`, the `HWND`, `HMONITOR`, and `HMENU` types
now alias to `*mut c_void` instead of `isize`.
- Removed `KeyEventExtModifierSupplement`, and made the fields `text_with_all_modifiers` and
`key_without_modifiers` public on `KeyEvent` instead.
- Move `window::Fullscreen` to `monitor::Fullscreen`.
- Renamed "super" key to "meta", to match the naming in the W3C specification.
`NamedKey::Super` still exists, but it's non-functional and deprecated, `NamedKey::Meta` should be used instead.
- Move `IconExtWindows` into `WinIcon`.
### Removed
- Remove `Event`.
- Remove already deprecated APIs:
- `EventLoop::create_window()`
- `EventLoop::run`.
- `EventLoopBuilder::new()`
- `EventLoopExtPumpEvents::pump_events`.
- `EventLoopExtRunOnDemand::run_on_demand`.
- `VideoMode`
- `WindowAttributes::new()`
- `Window::set_cursor_icon()`
- On iOS, remove `platform::ios::EventLoopExtIOS` and related `platform::ios::Idiom` type.
This feature was incomplete, and the equivalent functionality can be trivially achieved outside
of `winit` using `objc2-ui-kit` and calling `UIDevice::currentDevice().userInterfaceIdiom()`.
- On Web, remove unused `platform::web::CustomCursorError::Animation`.
- Remove the `rwh_04` and `rwh_05` cargo feature and the corresponding `raw-window-handle` v0.4 and
v0.5 support. v0.6 remains in place and is enabled by default.
- Remove `DeviceEvent::Added` and `DeviceEvent::Removed`.
- Remove `DeviceEvent::Motion` and `WindowEvent::AxisMotion`.
- Remove `MonitorHandle::size()` and `refresh_rate_millihertz()` in favor of
`MonitorHandle::current_video_mode()`.
- On Android, remove all `MonitorHandle` support instead of emitting false data.
- Remove `impl From<u64> for WindowId` and `impl From<WindowId> for u64`. Replaced with
`WindowId::into_raw()` and `from_raw()`.
- Remove `dummy()` from `WindowId` and `DeviceId`.
- Remove `WindowEvent::Touch` and `Touch` in favor of the new `PointerKind`, `PointerSource` and
`ButtonSource` as part of the new pointer event overhaul.
- Remove `Force::altitude_angle`.
- Remove `Window::inner_position`, use the new `Window::surface_position` instead.
- Remove `CustomCursorExtWeb`, use the `CustomCursorSource`.
- Remove `CustomCursor::from_rgba`, use `CustomCursorSource` instead.
- Remove `ApplicationHandler::exited`, the event loop being shut down can now be listened to in
the `Drop` impl on the application handler.
- Remove `NamedKey::Space`, match on `Key::Character(" ")` instead.
- Remove `PartialEq` impl for `WindowAttributes`.
### Fixed
- On Orbital, `MonitorHandle::name()` now returns `None` instead of a dummy name.
- On iOS, fixed `SurfaceResized` and `Window::surface_size` not reporting the size of the actual surface.
- On macOS, fixed the scancode conversion for audio volume keys.
- On macOS, fixed the scancode conversion for `IntlBackslash`.
- On macOS, fixed redundant `SurfaceResized` event at window creation.

## 0.10.0
- Add support for `Touch` for emscripten backend.
- Added support for `DroppedFile`, `HoveredFile`, and `HoveredFileCancelled` to X11 backend.
- **Breaking:** `unix::WindowExt` no longer returns pointers for things that aren't actually pointers; `get_xlib_window` now returns `Option<std::os::raw::c_ulong>` and `get_xlib_screen_id` returns `Option<std::os::raw::c_int>`. Additionally, methods that previously returned `libc::c_void` have been changed to return `std::os::raw::c_void`, which are not interchangeable types, so users wanting the former will need to explicitly cast.
- Added `set_decorations` method to `Window` to allow decorations to be toggled after the window is built. Presently only implemented on X11.
- Raised the minimum supported version of Rust to 1.20 on MacOS due to usage of associated constants in new versions of cocoa and core-graphics.
- Added `modifiers` field to `MouseInput`, `MouseWheel`, and `CursorMoved` events to track the modifiers state (`ModifiersState`).
- Fixed the emscripten backend to return the size of the canvas instead of the size of the window.

- Dead keys now work properly on X11, no longer resulting in a panic.
- On X11, input method creation first tries to use the value from the user's `XMODIFIERS` environment variable, so application developers should no longer need to manually call `XSetLocaleModifiers`. If that fails, fallbacks are tried, which should prevent input method initialization from ever outright failing.

## 0.13.0
- Implement `WindowBuilder::with_maximized`, `Window::set_fullscreen`, `Window::set_maximized` and `Window::set_decorations` for MacOS.
- Implement `WindowBuilder::with_maximized`, `Window::set_fullscreen`, `Window::set_maximized` and `Window::set_decorations` for Windows.
- On Windows, `WindowBuilder::with_fullscreen` no longer changing monitor display resolution.
- Overhauled X11 window geometry calculations. `get_position` and `set_position` are more universally accurate across different window managers, and `get_outer_size` actually works now.
- Fixed SIGSEGV/SIGILL crashes on macOS caused by stabilization of the `!` (never) type.
- Implement `WindowEvent::HiDPIFactorChanged` for macOS
- On X11, input methods now work completely out of the box, no longer requiring application developers to manually call `setlocale`. Additionally, when input methods are started, stopped, or restarted on the server end, it's correctly handled.
- Implemented `Refresh` event on Windows.
- Properly calculate the minimum and maximum window size on Windows, including window decorations.
- Map more `MouseCursor` variants to cursor icons on Windows.
- Corrected `get_position` on macOS to return outer frame position, not content area position.
- Corrected `set_position` on macOS to set outer frame position, not content area position.
- Added `get_inner_position` method to `Window`, which gets the position of the window's client area. This is implemented on all applicable platforms (all desktop platforms other than Wayland, where this isn't possible).
- **Breaking:** the `Closed` event has been replaced by `CloseRequested` and `Destroyed`. To migrate, you typically just need to replace all usages of `Closed` with `CloseRequested`; see example programs for more info. The exception is iOS, where `Closed` must be replaced by `Destroyed`.

## 0.14.0
- Created the `Copy`, `Paste` and `Cut` `VirtualKeyCode`s and added support for them on X11 and Wayland
- Fix `.with_decorations(false)` in macOS
- On Mac, `NSWindow` and supporting objects might be alive long after they were `closed` which resulted in apps consuming more heap then needed. Mainly it was affecting multi window applications. Not expecting any user visible change of behaviour after the fix.
- Fix regression of Window platform extensions for macOS where `NSFullSizeContentViewWindowMask` was not being correctly applied to `.fullsize_content_view`.
- Corrected `get_position` on Windows to be relative to the screen rather than to the taskbar.
- Corrected `Moved` event on Windows to use position values equivalent to those returned by `get_position`. It previously supplied client area positions instead of window positions, and would additionally interpret negative values as being very large (around `u16::MAX`).
- Implemented `Moved` event on macOS.
- On X11, the `Moved` event correctly use window positions rather than client area positions. Additionally, a stray `Moved` that unconditionally accompanied `Resized` with the client area position relative to the parent has been eliminated; `Moved` is still received alongside `Resized`, but now only once and always correctly.
- On Windows, implemented all variants of `DeviceEvent` other than `Text`. Mouse `DeviceEvent`s are now received even if the window isn't in the foreground.
- `DeviceId` on Windows is no longer a unit struct, and now contains a `u32`. For `WindowEvent`s, this will always be 0, but on `DeviceEvent`s it will be the handle to that device. `DeviceIdExt::get_persistent_identifier` can be used to acquire a unique identifier for that device that persists across replugs/reboots/etc.
- Corrected `run_forever` on X11 to stop discarding `Awakened` events.
- Various safety and correctness improvements to the X11 backend internals.
- Fixed memory leak on X11 every time the mouse entered the window.
- On X11, drag and drop now works reliably in release mode.
- Added `WindowBuilderExt::with_resize_increments` and `WindowBuilderExt::with_base_size` to X11, allowing for more optional hints to be set.
- Rework of the wayland backend, migrating it to use [Smithay's Client Toolkit](https://github.com/Smithay/client-toolkit).
- Added `WindowBuilder::with_window_icon` and `Window::set_window_icon`, finally making it possible to set the window icon on Windows and X11. The `icon_loading` feature can be enabled to allow for icons to be easily loaded; see example program `window_icon.rs` for usage.
- Windows additionally has `WindowBuilderExt::with_taskbar_icon` and `WindowExt::set_taskbar_icon`.

- Fixed detection of `Pause` and `Scroll` keys on Windows.
- On Windows, alt-tabbing while the cursor is grabbed no longer makes it impossible to re-grab the cursor.
- On Windows, using `CursorState::Hide` when the cursor is grabbed now ungrabs the cursor first.
- Implemented `MouseCursor::NoneCursor` on Windows.
- Added `WindowBuilder::with_always_on_top` and `Window::set_always_on_top`. Implemented on Windows, macOS, and X11.

- More hints are set by default on X11, including `_NET_WM_PID` and `WM_CLIENT_MACHINE`. Note that prior to this, the `WM_CLASS` hint was automatically set to whatever value was passed to `with_title`.

## 0.16.2
- On Windows, non-resizable windows now have the maximization button disabled. This is consistent with behavior on macOS and popular X11 WMs.
- Corrected incorrect `unreachable!` usage when guessing the DPI factor with no detected monitors.
## 0.16.1
- Added logging through `log`. Logging will become more extensive over time.
- On X11 and Windows, the window's DPI factor is guessed before creating the window. This _greatly_ cuts back on unsightly auto-resizing that would occur immediately after window creation.
- Fixed X11 backend compilation for environments where `c_char` is unsigned.
## 0.16.0
- Windows additionally has `WindowBuilderExt::with_no_redirection_bitmap`.
- **Breaking:** Removed `VirtualKeyCode::LMenu` and `VirtualKeyCode::RMenu`; Windows now generates `VirtualKeyCode::LAlt` and `VirtualKeyCode::RAlt` instead.
- On X11, exiting fullscreen no longer leaves the window in the monitor's top left corner.
- **Breaking:** `Window::hidpi_factor` has been renamed to `Window::get_hidpi_factor` for better consistency. `WindowEvent::HiDPIFactorChanged` has been renamed to `WindowEvent::HiDpiFactorChanged`. DPI factors are always represented as `f64` instead of `f32` now.
- The Windows backend is now DPI aware. `WindowEvent::HiDpiFactorChanged` is implemented, and `MonitorId::get_hidpi_factor` and `Window::hidpi_factor` return accurate values.
- Implemented `WindowEvent::HiDpiFactorChanged` on X11.
- On macOS, `Window::set_cursor_position` is now relative to the client area.
- On macOS, setting the maximum and minimum dimensions now applies to the client area dimensions rather than to the window dimensions.
- On iOS, `MonitorId::get_dimensions` has been implemented and both `MonitorId::get_hidpi_factor` and `Window::get_hidpi_factor` return accurate values.
- On Emscripten, `MonitorId::get_hidpi_factor` now returns the same value as `Window::get_hidpi_factor` (it previously would always return 1.0).
- **Breaking:** The entire API for sizes, positions, etc. has changed. In the majority of cases, winit produces and consumes positions and sizes as `LogicalPosition` and `LogicalSize`, respectively. The notable exception is `MonitorId` methods, which deal in `PhysicalPosition` and `PhysicalSize`. See the documentation for specifics and explanations of the types. Additionally, winit automatically conserves logical size when the DPI factor changes.
- **Breaking:** All deprecated methods have been removed. For `Window::platform_display` and `Window::platform_window`, switch to the appropriate platform-specific `WindowExt` methods. For `Window::get_inner_size_points` and `Window::get_inner_size_pixels`, use the `LogicalSize` returned by `Window::get_inner_size` and convert as needed.
- HiDPI support for Wayland.
- `EventsLoop::get_available_monitors` and `EventsLoop::get_primary_monitor` now have identical counterparts on `Window`, so this information can be acquired without an `EventsLoop` borrow.
- `AvailableMonitorsIter` now implements `Debug`.
- Fixed quirk on macOS where certain keys would generate characters at twice the normal rate when held down.
- On X11, all event loops now share the same `XConnection`.
- **Breaking:** `Window::set_cursor_state` and `CursorState` enum removed in favor of the more composable `Window::grab_cursor` and `Window::hide_cursor`. As a result, grabbing the cursor no longer automatically hides it; you must call both methods to retain the old behavior on Windows and macOS. `Cursor::NoneCursor` has been removed, as it's no longer useful.
- **Breaking:** `Window::set_cursor_position` now returns `Result<(), String>`, thus allowing for `Box<Error>` conversion via `?`.
