Adds fullscreen using native web APIs to the stdweb and web-sys backends.
Due to limitations of browser APIs, requests for fullscreen can only be fulfilled during a short-lived user-triggered event. This commit does automatically handle that under the hood, but it does introduce unavoidable latency in full-screening the canvas.

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.

* macOS/iOS: Fix auto trait impls of `EventLoopProxy`
`EventLoopProxy<T>` allows sending `T` from an arbitrary thread that
owns the proxy object. Thus, if `T` is `!Send`, `EventLoopProxy<T>` must
not be allowed to leave the main thread.
`EventLoopProxy<T>` uses `std::sync::mpsc::Sender` under the hood,
meaning the `!Sync` restriction of it also applies to
`EventLoopProxy<T>`. That is, even if `T` is thread-safe, a single
`EventLoopProxy` object cannot be shared between threads.

* Run rustfmt
* Add CHANGELOG entry and comment
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.
Closes#865
* Add relative pointer movement for Wayland
* Format changed code with rustfmt
* Wayland: merge window and device event queues into one
* Replace map_or_else call for simplification
* Format everything and add rustfmt to travis
* Remove extern crate winit from examples and add force_multiline_blocks
* Format the code properly
* Fix inconsistent period in PULL_REQUEST_TEMPLATE.md

This decorelates the window management from the actual user content,
meaning:
- the created window no longer needs the user to draw something to
start existing
- it reduces our need to do roundtrips during initialization to
avoid protocol errors
* Support listing available video modes for a monitor
* Use derivative for Windows `MonitorHandle`
* Update FEATURES.md
* Fix multiline if statement
* Add documentation for `VideoMode` type
The cursor visibility docs were still outdated from the rename and
talking about setting the invisibility, rather than visibility.
The platform-specific docs are unchanged since those should be fine and
the rest has been adapted using similar docs.
* Fix request_redraw with Poll and WaitUntil(time_in_the_past) on Windows
`Window::request_redraw` now fires a `RedrawRequested` event when
called from an `Event::EventsCleared` callback while the control
flow is set to `Poll`. A control flow of `WaitUntil(resume_time)`,
will now also fire the `RedrawRequested` event when `resume_time`
is in the past.
* Prevent panic on x11 when WaitUntil(resume_time) is in the past
* Prevent panic on wayland when WaitUntil(resume_time) is in the past
* First name consistency pass. More to come!
* Remove multitouch variable (hopefully this compiles!)
* Remove CreationError::NotSupported
* Add new error handling types
* Remove `get_` prefix from getters.
This is as per the Rust naming conventions recommended in
https://rust-lang-nursery.github.io/api-guidelines/naming.html#getter-names-follow-rust-convention-c-getter
* Make changes to Window position and size function signatures
* Remove CreationError in favor of OsError

iOS on a Windows machine (thanks apple :/) but this should be one of
several commits to get it working.

* port ios winit el2.0 implementation to the new rust-windowing repo
* unimplemented! => unreachable
trailing comma in CFRunLoopTimerCallback
* implement get_fullscreen
* add iOS specific platform documentation. Add a TODO about how to possibly extend the iOS backend to work have methods callable from more than just the main thread
* assert that window is only dropped from the main thread
* assert_main_thread called from fewer places
* Prevent the event loop from pausing after entering modal loop
After clicking the window title bar or border (for a drag or resize),
the event loop pauses until the mouse is moved. This change relays
the WM_NCLBUTTONDOWN message to the dummy window where it queues
a redraw and consumes the message. This effectively jumpstarts
the modal loop and it continues to fire draw requests.
* Handle WM_NCLBUTTONDOWN in public_window_callback instead of relaying.
Relaying the WM_NCLBUTTONDOWN message to the modal window turned out
to be unnecessary.
* Add additional numpad key mappings
Since some platforms have already used the existing `Add`, `Subtract`
and `Divide` codes to map numpad keys, the X11 and Wayland platform has
been updated to achieve parity between platforms. On macOS only the
`Subtract` numpad key had to be added.
Since the numpad key is different from the normal keys, an alternative
option would be to add new `NumpadAdd`, `NumpadSubtract` and
`NumpadDivide` actions, however I think in this case it should be fine
to map them to the same virtual key code.
* Add Numpad PageUp/Down, Home and End on Wayland
* Use `XRRGetScreenResourcesCurrent` when avail.

XNextEvent will block for input while holding the global Xlib mutex.
This will cause a deadlock in even the most trivial multi-threaded
application because OpenGL functions will need to hold the Xlib mutex
too.
Add EventsLoop::poll_one_event and EventsLoop::wait_for_input to provide
thread-safe functions to poll and wait events from the X11 event queue
using unix select(2) and XCheckIfEvent.
This is a somewhat ugly workaround to an ugly problem.

This commit restricts an Xfwm4-specific DPI-preserving hack to Xfwm4
only. The hack saves and restores the DPI-adjusted size until the actual
size matches. On tiling WMs like i3 this fails, since the size is
constrained by the layout. This in turn causes a never-ending
XResizeWindow vs. XConfigureWindow fight between the WM and the client,
making the WM, winit client, and Xorg consume all CPU cycles available.

In some cases, wl_outputs can be removed without the compositor
notifying the surfaces using leave/enter events. This breaks the DPI and
resize stuff since the windows' list of monitors were not updated.
Now, wl_output removals are handled and windows are updated accordingly.

* Add period at the end of sentences in documentation.
Motivation:
This allows VirtualKeyCode variants to be stored in a BTreeSet.
Unlike HashSets, BTreeSets implement Ord and Hash, allowing them to be
keys in a {Hash|BTree}Maps. This is nice, e.g. when implementing
keyboard shortcuts functionality, which maps a set of pressed keys to
some action.
Fixes#691
Dropping a window before running the `EventsLoop` results in events
still being queued when `XDestroyWindow` is called, so events like
`XI_Enter` (the culprit in this case) will still be processed.
Simply checking that the window still exists before calling
`query_pointer` was enough to solve the problem.
On Mojave, views automatically become layer-backed shortly after being added to
a window. Changing the layer-backedness of a view breaks the association
between the view and its associated OpenGL context. To work around this, on
Mojave we explicitly make the view layer-backed up front so that AppKit doesn't
do it itself and break the association with its context.
This was breaking the `window` example in `glutin`.

Fixes#523
Prior to changing the cursor state, we now check the current grab
state, since it can be invalidated by alt-tabbing and other things.
`CursorState::Hide` is also implemented now.
The cursor name is now wrapped in a `Cursor` struct to allow
multithreaded access.
`Window::set_cursor_state` has been reworked to use
`execute_in_thread`. Two unneeded `transmute` calls were also
removed.
The `WM_SETCURSOR` handler is much more readable now.
`MonitorId::get_adapter_name` has been removed, since it's dead
code and appears to be a relic from 4 years ago.
* Windows: CursorState::Grab no longer hides cursor
`MouseCursor::NoneCursor` has been implemented to allow for
equivalent behavior to the older implementation.
Windows and X11 now have consistent cursor grabbing behavior.
macOS still needs to be updated.
* Windows: Grabbing auto-hides again (for now)
This API needs more work, so let's stick to a bug fix and some
refactoring. However, it now hides using a different technique
than it did originally, which applies instantly instead of after
mouse movement.
* Windows: Fix panic for set_fullscreen(None) (#501)
* Add condition to prevent panic
Trying to call set_fullscreen(None) on a window that has never been in
fullscreen mode caused a panic before this change.
The responsible method now simply checks if this precondition is met and
returns (does nothing) otherwise.
* Add entry to CHANGELOG
* Add platform specification to CHANGELOG entry
Forgot to add that the to_fullscreen(None) bugfix is Windows only in
CHANGELOG.
* X11: General cleanup
This is almost entirely internal changes, and as usual, doesn't actually
fix any problems people have complained about.
- `XSetInputFocus` can't be called before the window is visible. This
was previously handled by looping (with a sleep) and querying for the
window's state until it was visible. Now we use `XIfEvent`, which blocks
until we receive `VisibilityNotify`. Note that this can't be replaced
with an `XSync` (I tried).
- We now call `XSync` at the end of window creation and check for
errors, assuring that broken windows are never returned. When creating
invisible windows, this is the only time the output buffer is flushed
during the entire window creation process (AFAIK). For visible windows,
`XIfEvent` will generally flush, but window creation has overall been
reduced to the minimum number of flushes.
- `check_errors().expect()` has been a common pattern throughout the
backend, but it seems that people (myself included) didn't make a
distinction between using it after synchronous requests and asynchronous
requests. Now we only use it after async requests if we flush first,
though this still isn't correct (since the request likely hasn't been
processed yet). The only real solution (besides forcing a sync *every
time*) is to handle asynchronous errors *asynchronously*. For future
work, I plan on adding logging, though I don't plan on actually
*handling* those errors; that's more of something to hope for in the
hypothetical async/await XCB paradise.
- We now flush whenever it makes sense to. `util::Flusher` was added to
force contributors to be aware of the output buffer.
- `Window::get_position`, `Window::get_inner_position`,
`Window::get_inner_size`, and `Window::get_outer_size` previously all
required *several* round-trips. On my machine, it took an average of
around 80µs. They've now been reduced to one round-trip each, which
reduces my measurement to 16µs. This was accomplished simply by caching
the frame extents, which are expensive to calculate (due to various
queries and heuristics), but change infrequently and predictably. I
still recommend that application developers use these methods sparingly
and generally prefer storing the values from `Resized`/`Moved`, as
that's zero overhead.
- The above change enabled me to change the `Moved` event to supply
window positions, rather than client area positions. Additionally, we no
longer generate `Moved` for real (as in, not synthetic)
`ConfigureNotify` events. Real `ConfigureNotify` events contain
positions relative to the parent window, which are typically constant
and useless. Since that position would be completely different from the
root-relative positions supplied by synthetic `ConfigureNotify` events
(which are the vast majority of them), that meant real `ConfigureNotify`
events would *always* be detected as the position having changed, so the
resultant `Moved` was multiple levels of misleading. In practice, this
meant a garbage `Moved` would be sent every time the window was resized;
now a resize has to actually change the window's position to be
accompanied by `Moved`.
- Every time we processed an `XI_Enter` event, we would leak 4 bytes via
`util::query_pointer` (`XIQueryPointer`). `XIButtonState` contains a
dynamically-allocated mask field which we weren't freeing. As this event
occurs with fairly high frequency, long-running applications could
easily accumulate substantial leaks. `util::PointerState::drop` now
takes care of this.
- The `util` module has been split up into several sub-modules, as it
was getting rather lengthy. This accounts for a significant part of this
diff, unfortunately.
- Atoms are now cached. Xlib caches them too, so `XInternAtom` wouldn't
typically be a round-trip anyway, but the added complexity is
negligible.
- Switched from `std::sync::Mutex` to `parking_lot::Mutex` (within this
backend). There appears to be no downside to this, but if anyone finds
one, this would be easy to revert.
- The WM name and supported hints are now global to the application, and
are updated upon `ReparentNotify`, which should detect when the WM was
replaced (assuming a reparenting WM was involved, that is). Previously,
these values were per-window and would never update, meaning replacing
the WM could potentially lead to (admittedly very minor) problems.
- The result of `Window2::create_empty_cursor` will now only be used if
it actually succeeds.
- `Window2::load_cursor` no longer re-allocates the cursor name.
- `util::lookup_utf8` previously allocated a 16-byte buffer on the heap.
Now it allocates a 1024-byte buffer on the stack, and falls back to
dynamic allocation if the buffer is too small. This base buffer size is
admittedly gratuitous, but less so if you're using IME.
- `with_c_str` was finally removed.
- Added `util::Format` enum to help prevent goofs when dealing with
format arguments.
- `util::get_property`, something I added way back in my first winit PR,
only calculated offsets correctly for `util::Format::Char`. This was
concealed by the accomodating buffer size, as it would be very rare for
the offset to be needed; however, testing with a buffer size of 1,
`util::Format::Long` would read from the same offset multiple times, and
`util::Format::Short` would miss data. This function now works correctly
for all formats, relying on the simple fact that the offset increases by
the buffer size on each iteration. We also account for the extra byte
that `XGetWindowProperty` allocates at the end of the buffer, and copy
data from the buffer instead of moving it and taking ownership of the
pointer.
- Drag and drop now reliably works in release mode. This is presumably
related to the `util::get_property` changes.
- `util::change_property` now exists, which should make it easier to add
features in the future.
- The `EventsLoop` device map is no longer in a mutex.
- `XConnection` now implements `Debug`.
- Valgrind no longer complains about anything related to winit (with
either the system allocator or jemalloc, though "not having valgrind
complain about jemalloc" isn't something to strive for).
* X11: Add better diagnostics when initialization fails
* X11: Handle XIQueryDevice failure
* X11: Use correct types in error handler
* Add Copy/Paste keys
This is only a tiny update which introduces the `Copy` and `Paste` keys
which are present on X11/Wayland/Windows. I'm not sure if this exists on
MacOS too, but I'm not able to test that and it doesn't have names but
just matches on the hex key values.
The "Copy" element is a reserved keyword in Rust but shouldn't cause any
conflicts in this scenario, this behavior falls in line with
https://docs.rs/winit/0.13.1/winit/enum.MouseCursor.html#variant.Copy,
but it would be possible to rename it. However `Copy` seems like the
most intuitive choice.
* Add Cut key, fix windows and update CHANGELOG
This introduces a bunch of minor fixes:
* The changes introduced by this branch have been added to the changelog
* Since related, the `Cut` key has also been added
* An attempt has been made to fix Windows
* Fix position of fallback comment
The new keys have been inserted at the wrong position, so the fallback
comment has been moved to the `_ => ...` section again.
* Fix windows build
Apparently there are no keys for Cut/Paste on Windows, so for now those
have been removed on Windows and only the `Copy` key has been added on
Windows, the changelog has been updated to reflect that.
Linux still implements Copy/Clone/Paste, but `Copy` is now working
properly on Wayland.
MacOS still does not have any of these keys.
* Remove Windows changes
Because the Windows design wasn't completely clear the VirtualKeyCode
variants are now only used on Linux with X11 and Wayland and ignored on
both MacOS and Windows.
The CHANGELOG has also been updated. Windows has been removed from it
and the Linux section has been clarified a bit.
* macOS: fix regression in 03c3e794097676888234b3cc82c01228dcbe48c8
fixed !decorations case and refactored logic to be a little easier to
read
* fix default case to inlude closable mask
* add comment to default case of macos platform attrs
* x11: Always receive Awakened event in run_forever
Do not reset the pending_wakeup boolean at the start of run_forever so
that each call to EventsLoopProxy::wakeup results in an Awakened event.
Fixes#462
* Update CHANGELOG.md
Fixes#467
All variants other than Text have been implemented. While Text can
be implemented using ToUnicode, that doesn't play nice with dead
keys, IME, etc.
Most of the mouse DeviceEvents were already implemented, but due
to the flags that were used when registering for raw input events,
they only worked when the window was in the foreground.
This is also a step forward for #338, as DeviceIds are no longer
useless on Windows. On DeviceEvents, the DeviceId contains that
device's handle. While that handle could ostensibly be used by
developers to query device information, my actual reason for
choosing it is because it's simply a very easy way to handle this.
As a fun bonus, this enabled me to create this method:
DevideIdExt::get_persistent_identifier() -> Option<String>
Using this gives you a unique identifier for the device that
persists across replugs/reboots/etc., so it's ideal for something
like device-specific configuration.
There's a notable caveat to the new DeviceIds, which is that the
value will always be 0 for a WindowEvent. There doesn't seem to be
any straightforward way around this limitation.
I was concerned that multi-window applications would receive n
copies of every DeviceEvent, but Windows only sends them to one
window per application.
Lastly, there's a chance that these additions will cause
antivirus/etc. software to detect winit applications as keyloggers.
I don't know how likely that is to actually happen to people, but
if it does become an issue, the raw input code is neatly
sequestered and would be easy to make optional during compilation.
* adding a multiwindow example
* Added NSAutoReleasepool for WindowDelegate::Drop
as setDelegate:nil autoreleases WindowDelegate during work.
Added NSAutoReleasepool for Window2::Create,
as it uses autorelease on objects while doing work.
Added NSAutoreleasepool for Window2::Drop
as nswindow::close uses autorelease on objects.
Added NSAutoreleasepool for IdRef.
Moved Window2 WinitWindow objc class to a static var, as we are creating
multiple windows.
* specifying return type for msg_send!
* removing example/recreate_window_leak.rs
* EventLoop, Shared, no need to retain dead weak ptr
* Change log entry added
* added comment about Shared.find_and_remove_window
* fixed code style errors
* Remove executable flag from os/macos.rs
This was causing me some grief while working on Windows, and it
doesn't belong here to begin with.
* Windows: get_position returns screen coordinates instead of workspace coordinates
Previously, get_position used GetWindowPlacement. As per the
documentation of WINDOWSTRUCT, the returned coordinates are in
workspace space, meaning they're relative to the taskbar. It's
also explicitly remarked that these coordinates should only be
used in conjunction with SetWindowPlacement, as mixing them with
functions expecting screen coordinates can cause unpleasantness.
Since our set_position (correctly) uses SetWindowPos, this meant
that passing the return of get_position to set_position would
cause the window to move.
We now use GetWindowRect, which returns screen coordinates. This
gives us both better consistency within the Windows backend and
across platforms.
Note that this only makes a difference if the taskbar is visible.
With the taskbar hidden, the values are exactly the same as before.
* Windows: Moved event position values are consistent with get_position
The old Moved values had two problems:
* They were obtained by casting a WORD (u16) straight to an i32.
This meant wrap-around would never be interpreted as negative,
thus negative positions (which are ubiquitous when using multiple
monitors) would result in positions around u16::MAX.
* WM_MOVE supplies client area positions, not window positions.
Switching to handling WM_WINDOWPOSCHANGED solves both of these
problems.
* Better documentation for Moved and Resized
* Replace Closed event with CloseRequested and Destroyed
Implements #434
The existing Closed event had ambiguous meaning, both in name and in
cross-platform behavior. Closed is now split into two more precise events:
* CloseRequested - the window has been requested to close, most commonly by
having clicked the window's close button. Whether or not you respond by
closing the window is up to you.
* Destroyed - the window has been destroyed, and can no longer be safely
used.
Most notably, now you can reliably implement classic patterns like
prompting the user to save their work before closing, and have the
opportunity to perform any necessary cleanup.
Migrating to the new API is straightforward. In most cases, you can simply
replace all existing usages of Closed with CloseRequested. For more
information, see the example programs, particularly handling_close and
multiwindow.
iOS applications must replace all usages of Closed with Destroyed, and
require no other changes.
* x11: Windows are Sync again
Fixes#472
* Add test ensuring that Window is Sync
Window must be Sync for Vulkano's Arc<FramebufferAbstract> to be usable.
This reverts commit 19cd53193b.
Testing fullscreen functionality revealed that windowDidResize is invoked in more cases than previously thought, causing the user's events to be eaten and HiDPI problems.
* Added helper function for make monitor from display.
* Implement get_current_monitor for macos
* Implemented with_fullscreen and set_fullscreen for macos

We are sending the mouse down event after the window resize has
completed, because Cocoa uses a modal event loop to implement window
resize. This leads to a mouse down without a matching mouse up.

Fixes#195Fixes#277Fixes#455
* Read `XMODIFIERS` explicitly/directly instead of calling `XSetLocaleModifiers` with an
empty string. This is useful for debugging purposes, and more clear to read and handle.
* Fallback to local input method if the one specified in `XMODIFIERS` is later closed on the
server end (i.e. if ibus/fcitx is terminated). Previously, that would cause the event loop
to freeze and usually also segfault.
* If using the fallback input method, respond to the `XMODIFIERS` input method later
becoming available. This means that the input method restarting is handled, and that even if
the program was started while ibus/fcitx/etc. was unavailable, it will start using it as
soon as it becomes available.
* Only one input method is opened for the whole event loop, with each window having its own
input context.
* IME works completely out of the box now, no longer requiring application developers to
call `setlocale` or `XSetLocaleModifiers`.
* Detailed error messages are provided if no input method could be opened. However, no
information is provided to the user if their intended `XMODIFIERS` input method failed to
open but the fallbacks (which will ostensibly always succeed) succeeded; in my opinion, this
is something that is best filled by adding a logging feature to winit.
XIM isn't thread-safe at all. Any call made to it from another thread will result in the
event loop freezing (this is why the old implementation of Drop for Window had that
problem).
XIM is now confined to one thread, and the existing API is maintained using channels. In
testing this with Alacritty, I initially thought the occasional slight lag on updating the
spot location was due to this change, but it's present without it as well.
* Try XOpenIM with different locale modifiers
Implements the solution suggested in
https://github.com/tomaka/winit/issues/277#issuecomment-337751136.
* Use empty XSetLocaleModifiers beforehand
Also, for modifiers, convert from length-based UTF-8 strings to
null-terminated bytestrings.
* Add CHANGELOG entry and comments
* make windows without decorations resizable and movable in macos

* On win32, force re-check of window size when changing min/max dimensions
* Fix freeze when setting min and max size
Fixes#79#414
This changes the implementation of Drop for Window to send a WM_DELETE_WINDOW ClientMessage,
offloading all the cleanup and window destruction to the event loop. Unsurprisingly, this
entails that the event loop now handles WM_DELETE_WINDOW using the behavior that was
previously contained in Window's Drop implementation, along with destroying the Window.
Not only does this mean that dropped windows are closed, but also that clicking the × button
on the window actually closes it now.
The previous implemention of Drop was also broken, as the event loop would be (seemingly
permenanently) frozen after its invocation. That was caused specifically by the mutex
locking, and is no longer an issue now that the locking is done in the event loop.
While I don't have full confidence that it makes sense for the Drop implementation to behave
this way, this is nonetheless a significant improvement. The previous behavior led to
inconsistent state, panics, and event loop breakage, along with not actually destroying the
window.
This additionally makes the assumption that users don't need Focused or CursorLeft events
for the destroyed window, as Closed is adequate to indicate unfocus, and users may not
expect to receive events for closed/dropped windows. In my testing, those specific events
were sent immediately after the window was destroyed, though this sort of behavior could be
WM-specific. I've opted to explicitly suppress those events in the case of the window no
longer existing.
* macOS: Allow hiding the title from the titlebar
* macOS: Allow making the titlebar transparent
* macOS: Give control over content view size
Allows setting `NSFullSizeContentViewWindowMask` with WindowBuilder.
* macOS: add `.with_titlebar_hidden` to WindowBuilderExt
* macOS: adds `titlebar_buttons_hidden` platform specific attribute
Due to the recent changes in the Rust compiler, unconstrained type
variables are now deduced to `!` instead of `()`. There are some
occurrences where `msg_send!` is used without constraining its return
type (relying on the assumption that they would be deduced to be `()`).
As a result, the macOS port of winit stopped working.
This PR fixes this issue (#426) by adding explicit return types to
such uses of `msg_send!`.
The fix for returning accurate window position lead to a regression
computing inner size in pixels. This commit resolves that by getting
inner size from the window ID winit caches and still resolving position
by climbing the window hierarchy.
Resolves#398
* x11: Support XRandR versions older than 1.5
Fixes#392
Previously, initializing the member `xrandr` of `XConnection` resulted
in a panic when symbols from XRandR version 1.5 were missing. There was
already code to handle older versions of XRandR but it was never
executed because of the panic.
The member `XConnection.xrandr` now contains only functions that can
safely be used with older versions. Additionally, this commit adds a new
member to `XConnection` of type `Option<ffi::XRandr>` that only contains
a value if version 1.5 functionality is present.
* x11: Document the xrandr* members of XConnection
Some window managers like i3wm will actually nest application windows
(like those opened by winit) within other windows to, for example, add
decorations. Initially when debugging this method on i3, the x and y
positions were always returned as "2".
The solution that other xlib abstractions use is to climb up the window
hierarchy until just below the root window, and that window must be used
to determine the appropriate position.
This patch doesn't take into account borders or the window's offset
within its parent, but it's much more usable than the original
implementation on certain WMs.
* macOS: Move the window if there is no title bar
On macOS by default windows can only be moved by clicking and
dragging on the titlebar, if we spawn a window without one we
need to set the `movableByWindowBackground` property.
Partial fix for #368
* macOS: Make moveByWindowBackground optional
Implements setting the property via WindowBuilderExt:
WindowBuilder::new()
.with_decorations(false)
.with_movable_by_window_background(true)
* Update CHANGELOG
This was previously hardcoded to 1.0. The values for physical size in
millimeters and pixel counts on each axis are used to compute the dpi
per monitor.
The `CursorMoved` events that are used to send position updates alongside `Focused` and
`CursorEntered` events were using incorrect values for the window ID. This is a direct
result of the X11 backend being hard to understand, as those values came from variables in
the top-level scope of the function, which one would assume to be valid throughout the
entirety of their scope. In reality, their validity is dependent on the event belonging to
the `XEvent` union, so very surprising things can happen if those variables are read in the
case of XInput2/XKB/etc. events. To prevent future accidents, the aforementioned variables
have been removed, and are now defined per-event instead.
Additionally, the `CursorMoved` event sent alongside `Focused` now uses the correct device
ID; it previously used the ID of a master keyboard, but now uses the ID of the pointer
paired to that keyboard. Note that for those using multi-pointer X, the correctness of this
ID is dependent on the correctness of the window manager's focus model.
This has been stubbed on all platforms other than X11. The X11 implementation has also been
revised to toggle correctly, as it was previously only able to remove decorations.
Fixes#256
`get_xlib_window` and `get_xlib_screen_id` previously returned `Option<*mut c_void>` by
casting integer IDs into pointers, which while producing no functionality issues, is
semantically incorrect and rather surprising. Worse still, the docs for `get_xlib_window`
stated that it was in fact a valid pointer.
Additionally, now all `unix::WindowExt` methods return `std::os::raw` types rather than
`libc` types; note that the two versions of `c_void` are not interchangeable in the eyes of
the compiler, so those wanting the `libc` type will need to explicitly cast.
This is a breaking change, and will require some trivial changes to glutin.
Previously, the maximization hints were being sent as two separate client messages: one for
horizontal, and one for vertical. That resulted in the window only being maximized
horizontally (at least with my WM). The corrected client message sets both of these hints at
once.
In the process of implementing that, the relevant components were refactored to use the util
module, as we gradually move towards a hopeful future of a more readable X11 backend.
Fixes#282
Some tiling window managers (i3, dwm, etc.) determine how a window should behave based on
its name. If the name is set after mapping, then window managers will check the name before
we set it, followed by them detecting it as a change when the name is actually set. That
results in the window briefly behaving in an unexpected way, followed by a rapid switch to
the expected behavior.
In accordance to section 4.1.2 of ICCCM, the name, decorations, size hints, and window
deletion redirection have all been moved up to be set before mapping.
* Update mouse pos after cursor enter event

* Send device_id
* Update other device id
* Fix windows import
* Remove deque for vec
* Just send event
* Use correct push_back method
* Push correct event
* Explicit mouse-related DeviceEvents
This makes the API more intuitive for common use-cases and allows us
to better propagate platform knowledge of motion semantics.
* Improve event naming consistency
* Clarify axis event forwards-compatibility
* Rename WindowEvent::MouseMoved/Entered/Left to CursorMoved/...
This emphasizes the difference between motion of the host GUI cursor,
as used for clicking on things, and raw mouse(-like) input data, as
used for first-person controls.
* Add support for windows and OSX, fix merging
* Fix warnings and errors on Linux
* Remove unnecessary breaking changes
* Add MouseWheel events to windows and OSX
* Fix bad push call.
* Fix docs, naming, and x11 events
* Remove mutability warning
* Add changelog entry
* wayland: upgrade wayland-window
This new version of wayland window considerably simplifies the
window handling for winit, meaning much of the previous juggling
is no longer needed, and the windows will appear even if nothing is
drawn.
* wayland: cleanup unused stuff
* Fix no primary monitor panic in XWayland
In this case try to use the first existing monitor instead of panicking.
Fixes#317
* Shift no monitor panic to x11::get_primary_monitor
* Update changelog with xll get_primary_monitor fallback
* Implement public API for high-DPI #105
* Recover get_inner_size_points and get_inner_size_pixels and change their implementation assuming get_inner_size() returns size in pixels
* Update changelog for high-DPI changes
This should trigger the compositor's mechanism for sending a
configure event, which should most of the time be processed
before any winit user actually tries to draw.
* Add an i386 target to travis
* Fix X11 on 32bit architectures
One would hope 32bit X11 was dead by now but apparently not :). Fix
the window hint setting code to not assume window IDs are 64bit as
apparently they are not in 32bit arches.
* wayland: don't create a second event_queue
As each EventsLoop has its own context, this is no longer necessary.
* wayland: buffer events rather than direct dispatch
Changes the behavior of the event loop to first internally
buffer the events generated by the wayland handlers, and then
dispatch them to the client's closure.
- It simplifies the event loop logic
- It makes it possible for the user to call window methods such as
`set_title()` or `set_inner_size()` without causing a deadlock
* wayland: add is_ready() & fix protocol errors
Adds a `is_ready()` method to the windows to advertize
when it is legal to start drawing, and fix a few wayland
protocol mishandling in the process.
