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 is required to help hardware accelerated libraries like glutin
that accept WindowBuilder instead of RawWindowHandle, since the api
to access builder properties directly was removed.

Commit f10a984 added `EventLoopWindowTarget::set_device_event_filter`
with for a mutable reference, however most winit APIs work with
immutable references, so altering API to play nicely with existing APIs.
This also disables device event filtering on debug example.
The `ndk` crate now implements [`HasRawWindowHandle` directly on
`NativeWindow`], relieving the burden to reimplement it on `winit`.
[`HasRawWindowHandle` directly on `NativeWindow`]: https://github.com/rust-windowing/android-ndk-rs/pull/274
Previously on X11, by default all global events were broadcasted to
every winit application. This unnecessarily drains battery due to
excessive CPU usage when moving the mouse.
To resolve this, device events are now ignored by default and users must
manually opt into it using
`EventLoopWindowTarget::set_filter_device_events`.
Fixes (#1634) on Linux.
This reverts commit 78e5a395da.
It was discovered that in some cases mesa will lock the back
buffer, e.g. when making context current, leading to resize
missing. Given that applications can restructure their rendering
to account for that, and that winit isn't limited to playing
nice with mesa reverting the original commit.
Since there's a "Platform-specific" header, it makes sense to put the
Linux-specific part under it. On the other hand, "Can only be called on
the main thread." is true for all platforms, not just iOS, so there is
no reason to call it out for iOS specifically.
When the window switches mode from normal to tabbed one, it doesn't
get resized, however the frame gets resized. This commit makes
winit to track resizes when frame changes instead of window.
Fixes#2191.
While most compositors provide server side decorations, the GNOME
does not, and won't provide them. Also Wayland clients must render
client side decorations.
Winit was already drawing some decorations, however they were bad
looking and provided no text rendering, so the title was missing.
However this commit makes use of the SCTK external frame similar to
GTK's Adwaita theme supporting text rendering and looking similar to
other GTK applications.
Fixes#1967.
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

`wl_pointer::set_cursor` expects a serial number of the last
`wl_pointer::enter` event. However other calls expect latest
observed pointer serial, so this commit tracks both and
use them as required by specification.
Fixes#2273.
This makes X11 and Wayland follow Windows and macOS, so the size of the
window could be set even though it has resizable attribute set to false.
Fixes#2242.
Both APIs are used to set application name. This commit unifies the API
between Wayland and X11, so downstream applications can remove platform
specific code when using `WindowBuilderExtUnix`.
Fixes#1739.
When all the receive from the compositor is `TouchEvent::Down` and
`TouchEvent::Up` for the same id, we would record the touch position in
the touch_points vector the first time. On `TouchEvent::Up` we'd find it
and report `TouchPhase::Ended` with that location. The next time we
receive `TouchEvent::Down` for the same id, we'd however unconditionally
append a new `TouchPoint` to `inner.touch_points`, with the new
position. On release however we'd find the earlier point and report its
location, which basically means that `TouchPhase::Ended` always and
forever reported the location of the very first touch down event.
Instead, this patch updates an existing touch point location with the
same id on `TouchDown`.
Fixes#1996
The commit without buffer attached should be done after setting all
top level size/application related properties. While c4df7ad7a added
commit after setting decorations, it accounted just for decorations,
however we should account for the min/max size and other attributes.
This commit brings `is_resizable` and `is_decorated`. Since the client
is responsible for both of them, they could be tracked without deep
syncing with server.
The scale factor being sent when the only monitor is disconnected and
reconnected is hard coded to 1.0. That may work by chance, if that's the
scale factor in use currently, but it does not work in the general case.
As a result, clients may end up with wrongly scaled or laid out window
contents after reconnect, as was reported over in
https://github.com/alacritty/alacritty/issues/5703, for example.
The problem was introduced by change 125ee0b, which caused an additional
ScaleFactorChanged event to be sent on monitor reconnect, but got the
scale factor wrong when the only monitor is disconnected and
reconnected.
This change fixes the problem by using the current monitor's scale
factor in this case. The event is still being sent as intended by
125ee0b.
Fixes#2123.
* Use NSView's inputContext instead of creating our own
This means that `set_ime_position` now properly invalidates the character coordinates.
* Make `set_ime_position` robust against moving windows
If you try to use `EventLoop::run_return` API in a way that you do on
demand polling of events it won't actually poll, since in such strategy
the `ControlFlow::Exit` is sent right before Wayland backend starts to
poll.
This was observed with smithay compositor Anvil which was doing this
particular thing leading to GNOME thinking that app isn't responding,
due to connection not being polled.
This commit adds an `EventLoopBuilder` struct to simplify event loop
customization and providing options to it upon creation. It also
deprecates the use of `EventLoop::with_user_event` in favor of the same
method on new builder, and replaces old platforms specific extension
traits with the new ones on the `EventLoopBuilder`.

The `cocoa` crate links to AppKit, which made the symbol `CGDisplayCreateUUIDFromDisplayID` from ApplicationServices/ColorSync (which AppKit uses internally) available to us on macOS 10.8 to 10.13.
However, this does not work on macOS 10.7 (where AppKit does not link to ColorSync internally). Instead of relying on this, we should just link to ApplicationServices directly.

* In MacOS, only disable menu bar in exclusive fullscreen
* Save and restore fullscreen options in set_fullscreen
* Don't always cache presentation options when entering exclusive fullscreen
This commit caches presentation options when entering exclusive fullscreen
only if we're coming from borderless fullscreen.
Then, when transitioning from exclusive -> borderless, if no cached presentation
options are present, then the default borderless options are applied.
This fixes the menu bar being unavailable when taking the following path:
[not fullscreen] -> [exclusive fullscreen] -> [borderless fullscreen].
Without this commit, the presentation options from [not fullscreen] were being
cached and then applied to [borderless fullscreen].
* Restore the window level when switching to exclusive fullscreen
The hack of using `CGShieldingWindowLevel() + 1` in borderless fullscreen needs
to be undone when switching from [borderless] -> [exclusive] fullscreen,
otherwise there are menu bar glitches when following a path through
[borderless] -> [exclusive] -> [borderless] modes.
Now, this might appear to conflict with the 'always on top' feature which uses
the 'floating window' level, but this feature appears to be broken anyway when
entering and exiting fullscreen with an always-on-top window. So, rather than
introducing logic to attempt to restore to the 'floating' level here, I think
it's better to do the simple thing for now and then introduce logic for
always-on-top windows when fixing the overall fullscreen behaviour.

Some video drivers could set display metrics to odd values, which can result in
extra large scale factors (e.g. winit is sending 720 for 5k screen on nvidia
binary drivers), so let's just drop them to prevent clients from using them.
The value 20 was picked, because the DPR for 8k @ 5 inch is ~18.36.
Fixes#1983.

* Use .map instead of a match, and remove comments saved by git
* Remove unnecessary pub keywords on `WakeSender` in x11/mod.rs
When disconnect the only monitor, scale factor is reset to 1.0. We need
to set it back when the monitor is reconnected.
We previously assume current window must be on an existing monitor, but
that's not true in case of reconnecting the only one monitor.
This commit also drops 'Theme' trait with its support types
in favor of 'FallbackFrame' meaning that winit will use some
predefined frame for the time being, since porting 'ConceptFrame'
will require adding font rendering librarires right into winit,
which is not desired.
Fixes#1889.
The inability to set the cursor using any of the named cursor files
likely indicates an error in the system on which we are running.
'WinitPointer::set_cursor' also does not have any way of returning an
error so just log the error to assist users in diagnosing the problem.

Fixes#1488.
`is_key_down` was only set to true when `insertText` was called.
Therefore `is_key_down` was actually meant to store whether the most
recently pressed key generated an `insertText` event, at which, winit
produces a `ReceivedCharacter`. The issue is that `insertText` is *not*
called for "key repeat", but winit wants to send `ReceivedCharacter`
events for "key repeat" too. To solve this, the `is_key_down` variable
was then checked in the `key_down` function to determine whether it was
valid to produce repeated `ReceivedCharacter` events during "key
repeat". However this check is not needed since `ReceivedCharacter` must
always be called if the key event has a non-empty `characters` property.
Furthermore `is_key_down` didn't actually store whether the previously
pressed character had an `insertText` event, because it was incorrectly
set to false on every "key up". This meant that if two keys were pressed
consecutively and then the first was released, then `is_key_down` was
set to false even if the most recent keypress did actually produce an
`insertText`.

This is called internally by NSApplication.run, and is not something we should call - I couldn't find the reasoning behind this being there in the first place, git blame reveals c38110cac from 2014, so probably a piece of legacy code.
Removing this fixes creating new windows when you have assigned a main menu to the application.
We allow to have RunLoop running only on the main thread. Which means if
we call Window::request_redraw() from other the thread then we have to
wait until some other event arrives on the main thread. That situation
is even worse when we have ControlFlow set to the `Wait` mode then user
will not ever render anything.

* Restore the ability to have fully transparent windows on Windows
Besides its original purpose, commit 6343059b "Fix Windows transparency
behavior to support fully-opaque regions (#1621)" also included some
changes considered cleanups, one of them was:
* Remove the `CreateRectRgn` call, since we want the entire window's region to
have blur behind it, and `DwnEnableBlurBehindWindow` does that by default.
But the original code actually disabled the blur effect for the whole
window by creating an empty region for it, because that allows for the
window to be truely fully transparent. With the blur effect in place,
the areas meant to be transparent either blur the things behind it
(until Windows 8) or are darkened (since Windows 8). This also means
that on Windows 8 and newer, the resulting colors are darker than
intended in translucent areas when the blur effect is enabled.
This restores the behaviour from winit <0.24 and fixes#1814.
Arguably, one might want to expose the ability to control the blur
region, but that is outside the scope of this commit.
* Remove useless WS_EX_LAYERED from transparent windows on Windows
`WS_EX_LAYERED` is not supposed to be used in combination with
`CS_OWNDC`. In winit, as it is currently used, `WS_EX_LAYERED` actually
has no effect at all. The only relevant call is to
`SetLayeredWindowAttributes`, which is required to make the window
visible at all with `WS_EX_LAYERED` set, but is called with full
opacity, i.e. there's no transparency involved at all.
The actual transparency is already achieved by using
`DwmEnableBlurBehindWindow`, so `WS_EX_LAYERED` and the call to
`SetLayeredWindowAttributes` can both be removed.
* Add DeviceEvent::MouseMove on web platform to support pointer lock
* Update changelog
* Add support for stdweb too
* Add mouse_delta to stdweb

* Conditionally link through ColorSync only if WINIT_LINK_COLORSYNC is set

* Document new macos env var in README
Following the changes in [1] this bumps ndk and ndk-glue to 0.3 and uses
the new constants. The minor version has been bumped to prevent
applications from running an older winit (without #1826) with a newer
ndk/ndk-glue that does not pass this `ident` through the `data` pointer
anymore.
[1]: https://github.com/rust-windowing/android-ndk-rs/pull/112
The issue was caused by calling SetCapture on a window which already
had the capture. The WM_CAPTURECHANGED handler assumed that it would
only run if the capture was lost, but that wasn't the case. This made
the handler to try to lock the window state mutex while it was already
locked.
The issue was introduced in #1797 (932cbe4).
ndk-glue currently sets both the `ident` field and user-data pointer to
`0` or `1` for the event pipe and input queue respectively, to tell
these sources apart. While it works to reinterpret this `data` pointer
as integer identifier it shouldn't be abused for that, in particular
when one may wish to provide extra information with an event in the
future; then the `data` field is used as pointer (or abused as abstract
value) for that.
This commit forwards "unknown" Wayland mouse buttons downstream via
'MouseButton::Other'. Possible values for those could be found in
<linux/input-event-codes.h>.
Also, since Wayland just forwards buttons from the kernel, which are
'u16', we must adjust 'MouseButton::Other' to take 'u16' instead of
'u8'.
This commit introduces a cross platform way to request a user attention
to the window via a 'request_user_attention' method on a Window struct.
This method is inspired by macOS's 'request_user_attention' method and
thus reuses its signature and semantics to some extent.
* Fix WindowEvent::ReceivedCharacter on web
The event was never sent to the application because of the unconditional
preventDefault() call on keydown.
Fixes#1741
* Don't scroll when pressing space on a focused canvas
After reaching keypress, we should prevent further propagation.
Relates to #1741
Building window with 'set_min_inner_size' was setting 'max_inner_size'
under the hood, thus completely disabling window resize, since
the window isn't resizeable on Wayland when its minimum size
is equal to its maximum size.
This patch removes an unneeded workaround for transparent windows on the
Windows platform. In addition, it simplifies a couple of related API calls:
* Remove the `CreateRectRgn` call, since we want the entire window's region to
have blur behind it, and `DwnEnableBlurBehindWindow` does that by default.
* Remove the `color_key` for `SetLayeredWindowAttributes`, since it's not used
(we're not passing `winuser::LWA_COLORKEY` to the flags).
The initial media query that's used to watch for device pixel ratio
changes should match. Unfortunately it doesn't with Safari and the
corresponding assertion fails. This is because resolution is not a
supported support property for queries. As a workaround, this patch
extends the query to optionally match for the webkit specific DPR
property directly.
This fixes#1734
* Update SCTK to 0.11.0
Updates smithay-client-toolkit to 0.11.0. The major highlight
of that updated, is update of wayland-rs to 0.27.0. Switching
to wayland-cursor, instead of using libwayland-cursor. It
also fixes the following bugs:
- Disabled repeat rate not being handled.
- Decoration buttons not working after tty switch.
- Scaling not being applied on output reenable.
- Crash when `XCURSOR_SIZE` is `0`.
- Pointer getting created in some cases without pointer capability.
- On kwin, fix space between window and decorations on startup.
- Incorrect size event when entering fullscreen when using
client side decorations.
- Client side decorations not being hided properly in fullscreen.
- Size tracking between fullscreen/tiled state changes.
- Repeat rate triggering multiple times from slow callback handler.
- Resizable attribute not being applied properly on startup.
- Not working IME
Besides those fixes it also adds a bunch of missing virtual key codes,
implements proper cursor grabbing, adds right click on decorations
to open application menu, disabled maximize button for non-resizeable
window, and fall back for cursor icon to similar ones, if the requested
is missing.
It also adds new methods to a `Theme` trait, such as:
- `title_font(&self) -> Option<(String, f32)>` - The font for a title.
- `title_color(&self, window_active: bool) -> [u8; 4]` - The color of
the text in the title.

* web: Allow event to be queued from inside the EventLoop handler
The Runner is behind a RefCell, which is mutably borrowed when the event
handler is being called. To queue events, `send_events` needs to check
`is_closed()` and the `is_busy` flag, but it cannot be done since the
RefCell is already locked. This commit changes the conditions to work
without needing a successful borrow.

Certain platforms like Wayland don't have a concept of
primary Monitor in particular. To indicate that
'primary_monitor' will return 'None' as well as in cases
where the primary monitor can't be detected.
Fixes#1683.
On certain platforms window couldn't be on any monitor
resulting in failures of 'current_monitor' function.
Such issue was happening on Wayland, since the window
isn't on any monitor, unless the user has drawn something into it.
Returning 'Option<MonitorHandle>' will give an ability to
handle such situations gracefully by properly indicating that
there's no current monitor.
Fixes#793.

On all platforms other than Linux/X11, the Subtract key was uniformly
used only for the Numpad. To make this cross-platform compatible, the
`-` key will now map to `Minus` on X11 instead of `Subtract`.
Since people have been confused about the difference between `Minus` and
`Subtract` in the past, the `Subtract` key has also been renamed to
`NumpadSubtract`. This is a breaking change that might be annoying to
downstream since there's no direct improvement, but it should help new
users in the future. Alternatively this could just be documented, rather
than explicitly mentioning the Numpad in the name.
