Inner panics could make it hard to trouble shoot the issues and for some
users ints not desirable.
The inner panics were left only when they are used to `assert!` during
development.
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.
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.
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.
A minimal example that shows an application running the event loop more
than once via `run_ondemand`
There is a 5 second delay between each run to help highlight problems
with destroying the window from the first loop.
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 utils in this module should help the users to activate the windows
they create, as well as manage activation tokens environment variables.
The API is essential for Wayland in the first place, since some
compositors may decide initial focus of the window based on whether
the activation token was during the window creation.
Fixes#2279.

This should provide a way to iterate all the tabs and select the last
tab. The tab indicies are now zero based as any other sane index.
Follow-up-to: c5941d105f (add tabbing API)
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.
Fixes issue on Wayland due to drop order, since TLS is being dropped
after the event loop, while it shouldn't. In particular it fixes the
crash in the window_run_return example.
The correct handling of this setting requires to change the events
we're getting from the macOS on the fly and call `interpretKeyEvents`,
which could affect handling of the next events, meaning that we can't
provide them on `KeyEvent`.
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.
