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.
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.
* 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
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.

Makes WindowAttributes public and adds window_attributes() getter to
WindowBuilder.
In version 0.27, the WindowAttributes struct was made private, but this
removed the ability to introspect the default WindowBuilder values.
* Use a bit less `unsafe` on iOS
I did test this in XCode 11.3's "Debug View Heirarchy", the NSStringRust problem is no longer applicable (likely because Rust got better at emitting correct debug info).
* Avoid using `id` on iOS
* fix clippy lints on Windows
* fix lints on other platforms

* again
* don't know what's goging on anymore
* fix examples

This adds `Window::set_window_level` to control the preferred
z level of the window.

Introduced in https://github.com/rust-windowing/winit/pull/2479; turns out the definitions were not entirely equal, the `kCFRunLoopEntry` that we were using previously was defined as `0` while the correct value is `1` (which meant the `unimplemented!()` branch suddenly started triggering)
Use the definitions that `core_foundation` exposes (almost the same, except `CFRunLoopSourceContext::perform` is not nullable, so we account for that as well).
Make sure `cargo doc` runs cleanly without any warnings in the CI - some
recently introduced but still allowing a PR to get merged.
In case someone wishes to add docs on private items, make sure those
adhere to the same standards.
This commit renames `Window::set_cursor_grab` to
`Window::set_cursor_grab_mode`. The new API now accepts enumeration
to control the way cursor grab is performed. The value could be: `lock`,
`confine`, or `none`.
This commit also implements `Window::set_cursor_position` for Wayland,
since it's tied to locked cursor.
Implements API from #1677.
This commit brings new Ime event to account for preedit state of input
method, also adding `Window::set_ime_allowed` to toggle IME input on
the particular window.
This commit implements API as designed in #1497 for desktop platforms.
