The `_lwp_self` function cannot be used to reliably determine the main
thread, see
https://github.com/alacritty/alacritty/issues/2631#issuecomment-676723289.
It might always be equal to the PID, but it's certainly not always 1
when the thread is the main thread.
However, Rust's built in `Thread::id` and `Thread::name` function will
always return `ThreadId(1)` and `Some("main")`. Since converting the
thread's ID to a number is not supported on stable Rust, checking that
the thread is labeled `Some("main")` seems like the most reliable
option. It should also be a good fallback in general.
* Move `ModifiersChanged` variant to `WindowEvent`
* macos: Fix flags_changed for ModifiersChanged variant move
I haven't look too deep at what this does internally, but at least
cargo-check is fully happy now. :)

* macos: Fire a ModifiersChanged event on window_did_resign_key
From debugging, I determined that macOS' emission of a flagsChanged
around window switching is inconsistent. It is fair to assume, I think,
that when the user switches windows, they do not expect their former
modifiers state to remain effective; so I think it's best to clear that
state by sending a ModifiersChanged(ModifiersState::empty()).

I don't know enough about the code to implement the fix as it is done on

* windows: Send ModifiersChanged(ModifiersState::empty) on KILLFOCUS
Very similar to the changes made in [1], as focus is lost, send an event
to the window indicating that the modifiers have been released.
It's unclear to me (without a Windows device to test this on) whether
this is necessary, but it certainly ensures that unfocused windows will
have at least received this event, which is an improvement.

* macos: Add a hook to update stale modifiers
Sometimes, `ViewState` and `event` might have different values for their
stored `modifiers` flags. These are internally stored as a bitmask in
the latter and an enum in the former.
We can check to see if they differ, and if they do, automatically
dispatch an event to update consumers of modifier state as well as the
stored `state.modifiers`. That's what the hook does.
This hook is then called in the key_down, mouse_entered, mouse_exited,
mouse_click, scroll_wheel, and pressure_change_with_event callbacks,
which each will contain updated modifiers.

Now, cover all events (that I can think of, at least) where stale

a ModifiersChanged event to be fired if something has changed.

Signed-off-by: Kristofer Rye <kristofer.rye@gmail.com>
* window_delegate: Synthetically set modifiers state to empty on resignKey
This logic is implemented similarly on other platforms, so we wish to
regain parity here. Originally this behavior was implemented to always
fire an event with ModifiersState::empty(), but that was not the best as
it was not necessarily correct and could be a duplicate event.
This solution is perhaps the most elegant possible to implement the
desired behavior of sending a synthetic empty modifiers event when a
window loses focus, trading some safety for interoperation between the
NSWindowDelegate and the NSView (as the objc runtime must now be
consulted in order to acquire access to the ViewState which is "owned"
by the NSView).

* Check for modifiers change in window events
* Fix modifier changed on macOS
Since the `mouse_entered` function was generating a mouse motion, which
updates the modifier state, a modifiers changed event was incorrectly
generated.
The updating of the modifier state has also been changed to make sure it
consistently happens before events that have a modifier state attached
to it, without happening on any other event.
This of course means that no `CursorMoved` event is generated anymore
when the user enters the window without it being focused, however I'd
say that is consistent with how winit should behave.

This restores default portable 'C' locale when target locale is unsupported
by X11 backend (Xlib).
When target locale is unsupported by X11, some locale-dependent Xlib
functions like `XSetLocaleModifiers` fail or have no effect triggering
later failures and panics.
When target locale is not valid, `setLocale` should normally leave the
locale unchanged (`setLocale` returns 'C'). However, in some situations,
locale is accepted by `setLocale` (`setLocale` returns the new locale)
but the accepted locale is unsupported by Xlib (`XSupportsLocale` returns
`false`).
Fix#636
* On Wayland, fix coordinates in touch events when scale factor isn't 1
* Explicitly state that Wayland is using LogicalPosition internally
* Fix CHANGELOG
* Don't discard high-precision cursor position data
Most platforms (X11, wayland, macos, stdweb, ...) provide physical
positions in f64 units, which can contain meaningful fractional
data. For example, this can be empirically observed on modern X11
using a typical laptop touchpad. This is useful for e.g. content
creation tools, where cursor motion might map to brush strokes on a
canvas with higher-than-screen resolution, or positioning of an object
in a vector space.
* Update CHANGELOG.md

* Rename hidpi_factor to scale_factor
* Deprecate WINIT_HIDPI_FACTOR environment variable in favor of WINIT_X11_SCALE_FACTOR
* Rename HiDpiFactorChanged to DpiChanged and update docs
I'm renaming it to DpiChanged instead of ScaleFactorChanged, since I'd
like Winit to expose the raw DPI value at some point in the near future,
and DpiChanged is a more apt name for that purpose.

* Another error pass
* Replace bad type signatures
* more fixins
* Fix compile errors
* Use `mio` for the X11 event loop
* Removes `calloop` from the X11 event loop, as the method of draining a
source using a closure provided to the `calloop::EventLoop` instance
conflicts with the need to deliver events directly to the callback
provided to `EventLoop::run`, in order to respond to the value provided by
`WindowEvent::HiDpiFactorChanged`.
* Implement interactive `HiDpiFactorChanged` event for X11
* Implement interactive `HiDpiFactorChanged` event for Wayland
* Run cargo fmt
* Fix Wayland not processing events from EventQueue
* Backport #981
* On X11, make `WINIT_HIDPI_FACTOR` dominate `Xft.dpi` in some cases
This commit makes `WINIT_HIDPI_FACTOR` dominate `Xft.dpi` in general and
adds a special value `0` for `WINIT_HIDPI_FACTOR` to use winit computed
DPI factor with randr over Xft.dpi.
* Use `randr` instead of `0` for auto dpi scaling
* Update CHANGELOG
* blow up on wrong env var
* Allow empty string for env var
* Move DeviceEvent handling to the message target window.
Previously, device events seem to have only been sent to one particular
window, and when that window was closed Winit would stop receiving
device events. This also allows users to create windowless event loops
that process device events - an intriguing idea, to say the least.

* Only issue `RedrawRequested` on final `Expose` event
Mutter can reposition window on resize, if it is behind mutter's "bounding box".
So, when you start winit window in maximized mode with CSD, mutter places its CSD
behind the GNOME's status bar initially, and then sends configure with the
exact same size as your current window. If winit decides to optimize calling
frame.resize(..) in this case, we won't call set_geometry(we're calling
it through resize) and GNOME won't reposition your window to be inside the
"bounding box", which is not a desired behavior for the end user.

replacing them with `pub(crate)` methods.
* Cleanup modifier state update using a macro
* Remove keys from modifier state when updating
* X11: Fix window creation hangs when another application is fullscreen
Previously, the X11 backend would block until a `VisibilityNotify` event
is received when creating a Window that is visible or when calling
`set_visible(true)` on a Window that is not currently visible. This
could cause winit to hang in situations where the WM does not quickly
send this event to the application, such as another window being
fullscreen at the time.
This behavior existed to prevent an X protocol error caused by setting
fullscreen state on an invisible window. This fix instead stores desired
fullscreen state when `set_fullscreen` is called (iff the window is not
visible or not yet visible) and issues X commands to set fullscreen
state when a `VisibilityNotify` event is received through the normal
processing of events in the event loop.
* Add window_debug example to facilitate testing
* Add a CHANGELOG entry
* Call `XUnmapWindow` if `VisibilityNotify` is received on an invisible window
* Prevent EventLoop from getting initialized outside the main thread
This only applies to the cross-platform functions. We expose functions
to do this in a platform-specific manner, when available.

Just before starting to poll/wait on calloop(mio), check if there
are already events pending in the internal buffer of our wayland
event queue. If so, dispatch them and force an instant wakeup from
the polling, in order to behave as if we were instantly woken up by
incoming wayland events.
When using OpenGL, mesa shares our wayland socket, and also reads
from it, especially if vsync is enabled as it'll do blocking reads.
When doing so, it may enqueue events in the internal buffer of our
event queue.
As the socket has been read, mio will thus not notify it to calloop
as read, and thus calloop will not know it needs to dispatch. In some
cases this can lead to some events being delivered much later than
they should. Combined with key repetition this can actually cause some
flooding of the event queue making this effect event worse.

Internally, `XFlush` calls `_XSend` to write data. It then calls
`XEventsQueued(display, QueuedAfterReading)`, which reads data from the
X server connection. This prevents the event loop source callback from
being run, as there is no longer data waiting on the socket.
Ideally, we would want to call `_XSend` directly to ensure that no
output is buffered by Xlib. However, this function is not exported as
part of Xlib's public API.
Testing with the `XFlush` call removed does not appear to adversely
affect the performance of an application. If any bugs should eventually
arise from this change, perhaps another function may be used in place of
`XFlush`, such as `XPending`, which writes buffered output but does not
so aggressively read from the X server connection.
