This also fixes macOS returning `None` in `Window::theme()` if no theme
override is set, instead it now returns the system theme.
MacOS and Wayland were the only ones working correctly according to the
documentation, which was an oversight. The documentation was "fixed"
now.
Fixes#3837.
We decided to remove them because they contained too little information
for the user to be useful. The assumption is that they were originally
implemented to enable gamepad support, which we already decided we are
not going to add directly to Winit.
This had no real use because we don't expose any information on
`DeviceId` except on Windows. But there we only expose the name. The
assumption is that this was originally added for gamepad support, which
never made it into Winit.
This allows the user more control over how they pass their application state
to Winit, and will hopefully allow `Drop` implementations on the application
handler to work in the future on all platforms.
Let the users wake up the event loop and then they could poll their
user sources.

There are AV rules out there which cause almost any
program that contains github URLs to become marked as malware.
While those rules are spurious, they're years old, and AV vendors have a
very poor reputation at appropriately following up with these problems.
Remove these strings from the panic data present in the binary
prevents binaries linking the winit from being spuriously marked as
Trojan:Win32/Wacatac.B!ml.
Tracing is a modern replacement for the log crate that allows for
annotating log messages with the function that they come from.

Closes: #3482
Removes the once_cell dependency, instead using std::sync::OnceLock and a
minimal polyfill for std::sync::LazyLock, which may be stabilized soon
(see rust-lang/rust#121377).
This should not require a bump in MSRV, as OnceLock was stabilized in 1.70,
which this crate is using.
Replace the `CustomCursorBuilder` with the `CustomCursorSource` and
perform the loading of the cursor via the
`EventLoop::create_custom_cursor` instead of passing it to the builder
itself.
This follows the `EventLoop::create_window` API.
Creating window when event loop is not running generally doesn't work,
since a bunch of events and sync OS requests can't be processed. This
is also an issue on e.g. Android, since window can't be created outside
event loop easily.
Thus deprecate the window creation when event loop is not running,
as well as other resource creation to running event loop.
Given that all the examples use the bad pattern of creating the window
when event loop is not running and also most example existence is
questionable, since they show single thing and the majority of their
code is window/event loop initialization, they wore merged into
a single example 'window.rs' example that showcases very simple
application using winit.
Fixes#3399.
Mainly fix typos in comments, but also some minor code changes:
* Rename `apply_on_poiner` to `apply_on_pointer`.
* Rename `ImeState::Commited` to `ImeState::Committed`
* Correct `cfg_attr` usage: `wayland_platfrom` -> `wayland_platform`.
This was supposed to be rolled out with the rwh v0.6 update, but it
was left behind for some reason. I've added this type back.

* make `EventLoopWindowTarget` independent of UserEvent type
the `EventLoopWindowTarget` is needed for window creation. conceptually,
only `EventLoop` and `EventLoopProxy` need to be parameterized, and all
other parts of the backend should be agnostic about the user event type,
parallel to how `Event<T>` is parameterized, but `WindowEvent` is not.
this change removes the dependency on the type of user events from the
`EventLoopWindowTarget` for the Windows backend, but keep a phantom data
to keep the API intact. to achieve this, I moved the `Receiver` end of
the mpsc channel from `ThreadMsgTargetData` into `EventLoop` itself, so
the `UserEvent` is only passed between `EventLoop` and `EventLoopProxy`,
all other part of the backend just use unit type as a placeholder for
user events.
it's similar to the macos backend where an erased `EventHandler` trait
object is used so all component except `EventLoop` and `EventLoopProxy`
need to be parameterized. however `EventLoop` of the Windows backend
already use an `Box<dyn FnMut>` to wrap the user provided event handler
callback, so no need for an dedicated trait object, I just modified the
wrapper to replace the placeholder user event with real value pulled
from the channel. I find this is the approach which need minimum change
to be made to existing code. but it does the job and could serve as a
starting point to future Windows backend re-works.
* fix CI clippy failure.
* make UserEventPlaceholder a new type instead of alias
* invariance is maintained by top-level EventLoopWindowTarget<T>
this field is transitional and her to keep API compatibility only.
the correct variance and such is already ensured by the top-level
`EventLoopWindowTarget`, just use `PhantomData<T>` here.
There seems to be many PRs relating to this issue, but they don't include all
platforms and for some reason lost steam. This PR again tries to make this
feature happen, and does it for all desktop platforms (x11, wayland, macos,
windows, web).
I think the best user of this feature and the reason I'm doing this is Bevy and
game engines in general. There non laggy hardware cursors with custom images are
very important. Game devs also like their PNGs so supporting platform native
cursor files is not that important, but I guess could be added too.

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.
