The only breaking change is that x11rb no longer reports an error when
querying the WmSizeHints of a window that does not have this property
set. For this reason, the return type of WmSizeHintsCookie::Reply()
changed from Result<WmSizeHints, SomeError> to
Result<Option<WmSizeHints>, SomeError>.
In update_normal_hints(), previously a cryptic error would be reported
to the caller. Instead, this now uses unwrap_or_default() to get a
WmSizeHints. All fields of WmSizeHints are Options, so this produces an
empty object.
resize_increments() queries a value from the window and returns an
Option. Previously, the error for "missing property" was turned into
None via .ok(). This commit adds a call to flatten() to also turn
"property not set" into None.
Finally, request_user_attention() queries a window's WmHints property
and updates one field of it. The code already uses unwrap_or_default()
to deal with missing properties, so just a call to flatten() is needed
to merge "missing property" and "error while querying" into one.
Other changes in x11rb do not seem to affect this crate.
x11rb's MSRV increased from 1.56 to 1.63, which is still below the MSRV
of this crate, which is 1.65.

Keep the user provided size in the original values and convert only
when we're getting a `configure` event. On some compositors will
have a scale available, so it'll work, however with some we'll
still have old 'pick 1` as default.
Also configure_bounds when compositor tells the user to pick the size,
that will ensure that initial `with_inner_size` won't grow beyond the
working area.
Fixes#3187.
The cursor hittest was not reloaded on window size changes, only
when `Window::request_inner_size` was called leading to regions
of the window being not clickable.
Also, don't try to apply hittest logic when user never requested a
hittest.

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`.

Window builder is always accessed by winit on the thread event loop
is on, thus it's safe to mark the data it gets as `Send + Sync`.
Each unsafe object is marked individually as `Send + Sync` instead
of just implementing `Send` and `Sync` for the whole builder.
The update is pretty minor, however we support now
`WindowEvent::Occluded` when xdg-shell v6 is available.
It also adds support for `Window::show_window_menu`.
Fixes#2927.
The new implementation of select_xkb_events apparently misconfigures
the server. This commit does a temporary fix by just reverting it to its
previous implementation.
This is temporary until I can figure out what Xlib is doing behind the
scenes or until I read xkbproto.pdf.

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.

At the moment, the with_x11_visual function takes a pointer and
immediately dereferences it to get the visual info inside. As it is safe
to pass a null pointer to this function, it is unsound. This commit
replaces the pointer parameter with a visual ID, and then uses that ID
to look up the actual visual under
the X11 setup. As this is what was already practically happening before,
this change shouldn't cause any performance downgrades.
This is a breaking change, but it's done in the name of soundness so it
should be okay. It should be trivial for end users to accommodate it,
as it's just a matter of getting the visual ID from the pointer to the
visual before passing it in.

Nothing changed from the user point of view, other than they should
use the `raw-window-handle`, which is objectively better, given that
it reduces the amount of `cfg` guards in downstream code.
#2662 renamed `VirtualKeyCode` to `Key` yet references to the former
type still exist in `src/platform_impl/linux/x11/events.rs`. As it
turns out the `mod events;` in `x11/mod.rs` was removed in the same PR,
but the file accidentally stuck around without being referenced anywhere
else.
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.
Although we document that applications can't keep windows between
separate run_ondemand calls it's possible that the application has only
just dropped their windows and we need to flush these requests to the
server/compositor.
This fixes the window_ondemand example - by ensuring the window from
the first loop really is destroyed before waiting for 5 seconds
and starting the second 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
Wayland:
I found the calloop abstraction a little awkward to work with while I was
trying to understand why there was surprising workaround code in the wayland
backend for manually dispatching pending events.
Investigating this further it looks like there may currently be several issues
with the calloop WaylandSource (with how prepare_read is used and with (not)
flushing writes before polling)
Considering the current minimal needs for polling in all winit backends I do
personally tend to think it would be simpler to just own the responsibility for
polling more directly, so the logic for wayland-client `prepare_read` wouldn't
be in a separate crate (and in this current situation would also be easier to fix)
I've tried to maintain the status quo with calloop + workarounds.
X11:
I found that the recent changes (4ac2006cbc) to port the X11 backend
from mio to calloop lost the ability to check for pending events before
needing to poll/dispatch. (The `has_pending` state being queried
before dispatching() was based on state that was filled in during
dispatching)
As part of the rebase this re-introduces the PeekableReceiver and
WakeSender which are small utilities on top of
`std::sync::mpsc::channel()`. This adds a calloop `PingSource`
so we can use a `Ping` as a generic event loop waker.
For taking into account false positive wake ups the X11 source now
tracks when the file descriptor is readable so after we poll via
calloop we can then specifically check if there are new X11 events
or pending redraw/user events when deciding whether to skip the
event loop iteration.
Unfortunately this isn't a total removal, for two reasons:
- We still need "libc" for the Xlib XIM implementation, for locales.
- BSD requires libc to check for main-threadedness.
First one we can likely resolve in the near future, not so sure about
the second one without using some weird pthreads trick.
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.

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.
Instead of a single `bool` indicating that a key press has occured and
no key has been released since then, we store the scancode of the last
pressed key (if it is a key that repeats when held). This fixes a bug
where pressing a new key while one is already held down will be flagged
as a repeat even though it is obviously not a repeat.
The change to xinput2 completely disabled IME support, thus we've got
a dead keys reporting, because nothing was eating the key events
anymore, however that's not what we really need, given that not
working IME makes it impossible for some users to type.
The proper solution is to not use Xlib at all for that and rely on
xcb and its tooling around the XIM and text compose stuff, so
we'll have full control over what is getting sent to the XIM/IC or not.
Fixes#2888.
