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).

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
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.
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.
* 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
* 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
* 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.
* Fix X11 screen resolution change using XrandR
The previous XF86 resolution switching was broken and everything
seems to have moved on to xrandr. Use that instead while cleaning
up the code a bit as well.
* Use XRandR for actual multiscreen support in X11
* Use actual monitor names in X11
* Get rid of ptr::read usage in X11
* Use a bog standard Vec instead of VecDeque
* Get rid of the XRandR mode switching stuff
Wayland has made the decision that apps shouldn't change screen
resolutions and just take the screens as they've been setup. In the
modern world where GPU scaling is cheap and LCD panels are scaling
anyway it makes no sense to make "physical" resolution changes when
software should be taking care of it. This massively simplifies the
code and makes it easier to extend to more niche setups like MST and
videowalls.
* Rename fullscreen options to match new semantics
* Implement XRandR 1.5 support
* Get rid of the FullScreen enum
Moving to just having two states None and Some(MonitorId) and then
being able to set full screen in the current monitor with something
like:
window.set_fullscreen(Some(window.current_monitor()));
* Implement Window::get_current_monitor()
Do it by iterating over the available monitors and finding which
has the biggest overlap with the window. For this MonitorId needs
a new get_position() that needs to be implemented for all platforms.
* Add unimplemented get_position() to all MonitorId
* Make get_current_monitor() platform specific
* Add unimplemented get_current_monitor() to all
* Implement proper primary monitor selection in X11
* Shut up some warnings
* Remove libxxf86vm package from travis
Since we're no longer using XF86 there's no need to keep the package
around for CI.
* Don't use new struct syntax
* Fix indentation
* Adjust Android/iOS fullscreen/maximized
On Android and iOS we can assume single screen apps that are already
fullscreen and maximized so there are a few methods that are implemented
by just returning a fixed value or not doing anything.
* Mark OSX/Win fullscreen/maximized unimplemented()!
These would be safe as no-ops but we should make it explicit so
there is more of an incentive to actually implement them.
* Rework MonitorId::get_native_identifier
* Try fix compilation
* Returns the monitor ID on wayland as well
* Try fix compilation
* Fix iOS compilation
Use the enum to make a single fullscreen API that's much more
consistent. Both set_fullscreen() and with_fullscreen() take the
same enum and support all the variations so you can build the window
however you want and switch between the modes at runtime.
There are two kinds of fullscreen. One where you take over the whole
output the other where you just set the window size to the screen
size and get rid of decorations. The first one already existed,
implement the second which is more common for normal desktop apps.
Use an enum to consolidate all the fullscreen states.
X11 always return the geometry in pixel units. Since
window.get_inner_size returns the size in points in other window manager
implementations X11 should also return in points instead of pixels.
ICCCM 4.1.2.5 (https://tronche.com/gui/x/icccm/sec-4.html#WM_CLASS)
states that:
> This property must be present when the window leaves the Withdrawn
> state and may be changed only while the window is in the Withdrawn
> state.
Previously, we would first map the window, and then set these
properties, causing sadness for window managers (#167,
tomaka/glutin#879). This patch changes that by setting the class and
name attributes immediately after the window is created, and before it
is mapped.
Fixes#167.
This expands input events to represent sub-pixel mouse positions, devices responsible for generating events, and raw
device-oriented events. The X11 back end is refactored to make full use of the new expressiveness. Other backends have
had new functionality minimally stubbed out, save for the macos backend which already supports sub-pixel mouse
positions.
