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.
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.
Split `Key` into clear categories, like `Named`, `Dead`, Character`, `Unidentified`
removing the `#[non_exhaustive]` from the `Key` itself.
Similar action was done for the `KeyCode`.

Inner panics could make it hard to trouble shoot the issues and for some
users it's not desirable.
The inner panics were left only when they are used to `assert!` during
development.
This reverts commit 9f91bc413fe20618bd7090829832bb074aab15c3 which
reverted the original patch which was merged without a proper review.
Fixes: #500.

There's no need to force the static on the users, given that internally
some backends were not using static in the first place.

Lifetimes don't work nicely when dealing with multithreaded environments
in the current design of the existing winit's event handling model, so
remove it in favor of `InnerSizeWriter` fences passed to client, so they
could try to update the size.
Fixes#1387.
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.
Considering the possibility of re-running an event loop via run_ondemand
then it's more correct to say that the loop is about to exit without
assuming it's going to be destroyed.
This renames all internal implementations of pump_events_with_timeout
to pump_events and makes them public.
Since all platforms that support pump_events support timeouts there's
no need to have a separate API.
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()`
Fixes: #2709
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`.
Add named variants for physical back and forward keys which could
be found on some mice. The macOS bits may not work on all the
hardware given that apple doesn't directly support such a thing.

The use of `Filter` was confusing so it was removed inverting the
behavior of the enum and methods using it.

Overhaul the keyboard API in winit to mimic the W3C specification
to achieve better crossplatform parity. The `KeyboardInput` event
is now uses `KeyEvent` which consists of:
- `physical_key` - a cross platform way to refer to scancodes;
- `logical_key` - keysym value, which shows your key respecting the
layout;
- `text` - the text produced by this keypress;
- `location` - the location of the key on the keyboard;
- `repeat` - whether the key was produced by the repeat.
And also a `platform_specific` field which encapsulates extra
information on desktop platforms, like key without modifiers
and text with all modifiers.
The `Modifiers` were also slightly reworked as in, the information
whether the left or right modifier is pressed is now also exposed
on platforms where it could be queried reliably. The support was
also added for the web and orbital platforms finishing the API
change.
This change made the `OptionAsAlt` API on macOS redundant thus it
was removed all together.

- Pass WM_SYSKEYDOWN to DefWindowProc
- Avoid intercepting WM_SYSCHAR to allow ALT+Space to work: removes ReceivedCharacter events for alt+keypress
- Intercept WM_MENUCHAR to disable bell sound
This should force the use of system libraries for Fontconfig
and freetype instead of building them with cmake if missing.
This also fixes compilation failures on nightly.
Fixes#2373.
winit's notion of "focus" is very simple; you're either focused or not.
However, Windows has both notions of focused window and active window
and paying attention only to WM_SETFOCUS/WM_KILLFOCUS can cause a window
to believe the user is interacting with it when they're not. (this
manifests when a user switches to another application between when a
winit application starts and it creates its first window)
