* Use AppKit's internal queuing mechanisms
This allows events to be queued in a more consistent order, they're now
interleaved with events that we handle immediately (like redraw events),
instead of being handled afterwards.
* Only queue events if necessary
This makes the call stack / backtraces easier to understand whenever
possible, and generally improves upon the order in which events are
delivered.
Changes relevant to Winit:
- `icrate` has been deprecated in favour of separate crates per
framework, in our case `objc2-foundation` and `objc2-app-kit` (and in
the future `objc2-ui-kit` on iOS).
- Moved `MainThreadMarker::run_on_main` to free-standing function
`run_on_main`.
- Changed how features work, this should result in less code that we
need to compile.
- Enums are now real structs instead of type-aliases and free constants.
This makes our use of `unsafe` to make the event handler temporarily 'static be local to a module, in a way that's (hopefully) much easier to reason about.
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.

Previously we had a sort of artificial split between these, but both were accessing each other's state, since it's really the same state!
It was especially difficult to follow what happens to the fullscreen state.
So instead, we basically merge the window and the delegate files.
This does unfortunately screw a bit with the git history, apologies to whoever reads this in the future!

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.
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 layers pump_events on a pump_events_with_timeout API, like we have
for Linux and Android.
This is just an internal implementation detail for now but we could
consider making pump_events_with_timeout public, or just making it so
that pump_events() takes the timeout argument.
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
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).
Use the definitions that `core_foundation` exposes (almost the same, except `CFRunLoopSourceContext::perform` is not nullable, so we account for that as well).
* Remove UnownedWindow::inner_rect
* Refactor custom view to use much less `unsafe`
The compiler fence is safe to get rid of now since `interpretKeyEvents` takes `&mut self`
* Refactor Window to use much less unsafe
* Refactor NSApplication usage to have much less unsafe
* Remove cocoa dependency
* Enable `deny(unsafe_op_in_unsafe_fn)` on macOS
Also re-enable clippy `let_unit_value` lint
* Remove #[macro_use] on macOS
* Refactor window delegate to use much less unsafe
* Begin abstraction over AppKit
* Clean up NSApplication delegate declaration
* Clean up NSApplication override declaration
* Clean up NSWindow delegate declaration
* Clean up NSWindow override declaration
* Clean up NSView delegate declaration
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.
