The new window rule allows to overwrite the stack layer. It can be
useful on wayland to force picture-in-picture surfaces (which are
xdg-toplevels at the moment) to be placed above fullscreen windows.
Keep above flag is unsuitable because fullscreen windows are placed
higher "above" windows.
CCBUG: 466016
Currently there is a 150ms delay before screen edge actions and
hotcorners are triggered; the cursor has to spend that much time there
before they'll activate. This is good for preventing accidental
activations, but also prevents and delays deliberate activations, which
are likely to be more annoying for the user.
To alleviate this, the delay is reduced to 75ms, which still prevents
most of the accidental activations in my testing, while making
deliberate activations faster and easier.
If the user wants to move a tiled window but changes their mind and tiles the window back to the previous
position, quickTileGeometryRestore() will return an error value beacause m_electricMaximizing is true and
the m_electricGeometryRestore is the same as the geometry of the window in the last tiled mode.
Now the geometry restore of the tiled window is true when starting interactive move, so we no longer need
to precompute it.
Changes for testQuickTilingPointerMove:
We need to attach a new image after the tiling window, so that updateElectricGeometryRestore can obtain
the same framegeometry as the framegeometry obtained during actual runtime.
Now testQuickTilingPointerMove can detect the error：If the user wants to move a tiled window but changes
their mind and tiles the window back to the previous position, quickTileGeometryRestore() will return an
error value beacause m_electricMaximizing is true and the m_electricGeometryRestore is the same as the
geometry of the window in the last tiled mode.

Currently when input panel is using overlay mode and the cursor rectangle
is below or above the screen area, the input panel may be placed off the
screen. The change ensure it is always placed within the screen area
using similar math like xdg_popup's slide_y constrain.
The wayland spec is not quite clear about the transforms, but the buffer
transform indicates a transform from wl_surface to wl_buffer or compositor
global coordinate space to composited buffer.
On the other hand, SurfaceItem assumes that the order is vice versa.
`flip-y | rotate-N` transforms are equivalent to `flip-x | rotate-N`.
However, it is not intuitive to express transforms that flip the y axis
via flip-x transforms. This change adds convenience aliases to improve
code readability and keep code intuitive, which is going to be needed in
order to drop TextureTransforms flags.
These can be useful in case a QRect needs to be mapped. One could
convert the QRect into a QRectF and then back to QRect, but given that
these conversion helpers are present in rendering hot paths, it would
be great to be more efficient and also potentially loosing precision
because of floating point arithmetic.
Makes it possible to easily target things in a window near your panel edge,
without bringing up your panel.
The `m_client` condition this MR removes appears to have been added solely to make autohiding panels appear instantly. See c4140d6f4e.

Instead of killing the window without asking, show the kill prompt
like it's done for X11 windows.
The window in question is exported through XDG foreign so the kill
helper can parent itself to it, and an activation token is also provided.
Also, the more contemporary desktop file name is now used for
identification rather than window class.
A no-display desktop file is installed for the kill helper so that it
can get a proper window icon and suppress startup notification.
This makes it consistent with the timeout used on X11.
The current ping timeout was also generally quite short, causing apps
to desaturate for brief moments when they were busy e.g. starting up
or loading large files.
Bouce keys suppresses additional key presses during a given interval
This is used by people with motor impairments or bad keyboards
It works by remembering the last input timestamp for a key
If an event's timestamp is too close to the last timestamp for that key the event is rejected

This allows KWin to securely identify the client for a given connection,
without relying on the process name.
This patch does not do anything meaningful with the application ID other
than store it.
This first version does not support kwin restarts, it can come
afterwards.
Testing done:
With latest flatpak, running `WAYLAND_DEBUG=1 flatpak run org.telegram.desktop |& grep security`
shows that flatpak itself bound the security context, and the client did not see it advertised.
It doesn't make sense for a window to become 1x1 pixels small. When we have
server side decorations we also know that the decoration takes a lot of
space, so this commit enforces a bigger minimum size for decorated windows

By default, hyper keys are interpreted as meta keys. However, due to
a Qt bug, it had been incorrectly mapped.
Commit b45b9090c3b66d541f57f8d049c22247f8c115ca in qtbase repo fixed it,
so the test needs adjustments.
Window::acceptsFocus() is not taken into account when a window is
activated using Workspace::activateWindow(). The main reason is because
of different input models on X11.
Instead, Window::takeFocus() should check itself if the window accepts
focus.
While applications are still restricted to sRGB, this allows working on sRGB
content on displays with a wide color gamut as the whole profile gets applied,
instead of just the VCGT.
CCBUG: 439135
libkwineffects was introduced when kwin used to be an executable. It
provided an api to implement effects and shielded from the technical
quirks in kwin.
Over the time, kwin internals had been split and abstractions were
refactored so they can be consumed in scripts or plugins. Besides that,
new ways to implement extensions have been introduced, which use
kwin's internal abstractions.
On the other hand, effects continue using libkwineffects specific apis.
This has a few issues: qtquick effects use both apis and it bites us,
duplicating same apis.
The best solution so far is to merge libkwineffects with libkwin, and
replace libkwineffects abstractions with libkwin abstractions, e.g.
EffectScreen -> Output, etc. This change takes care of adjusting libs.
Obviously, the main disadvantage of doing so is that binary effects
have to be recompiled every time new libkwin is released. But it's
already the case with libkwineffects too.
Some apps, notably Tablet KCM, will rebind the tablet interface and consume all events that should be sent to the GUI toolkit.
This commit sends events to every consumer and also stores the latest cursor indexed by wl_client instead of wl_resource.
BUG:473126
This makes the api of EffectWindow more similar to the api of Window. It
also makes more sense to keep such signals in EffectWindow. In the future,
the effect window can be dropped in favor of the window.
Instead of an external service (like KScreen) storing and restoring output configurations,
with this commit KWin takes over that responsibility. This allows it to, among other things,
generate appropriate configs for new sets of outputs immediately, and take KWin-internal information
about outputs into account when generating them.

At the moment, the wayland compositor has to handle the case of having
no workspace. This should be unnecessary and it creates a pesky cycling
dependency between Workspace and Compositor.
Given that the Workspace acts more like a container and kwin starts
accepting client connections after starting compositing, it's possible
to create the Workspace earlier and simplify the start() function a bit.
There's "major" and "minor" defines that can get implicitly included, for
example with musl libc. To prevent that from breaking compilation, rename
the methods
In many cases it's irrelevant, what we care about is whether given effect
is loaded and performs its function. So remove these paranoid checks
except the tests where it's important to use OpenGL compositing.
Instead, creating contexts that miss these features should fail directly,
making KWin fall back to software rendering.
While this commit also drops workarounds for broken drivers that do software
emulation for features we need, such workarounds belong into these drivers and
the user can still manually turn off compositing if needed.
Currently when we move the mouse the one render loop triggers a repaint.
When the cursor layer needs a new update we end up in the compositor
repainting the main content.
Even though painting should mostly no-op it still goes through all
existing items and effects to collect damage, still potentially making
the GL context current which could stall. A waste when we know we
haven't got anything to do. It's enough to cause noticable mouse lag on
some hardware.

Ensures that e.g. context menus move about with their parents when they
get moved around.
However, as per spec don't re-constrain the window when its positioner
is non-reactive. This change calculates the offset from its parent window
once initially and places the window relative to that whenever the parent
moves.
Only when the positioner is reactive, will it recalculate the placement fully.
BUG: 461994
`Placements::placeSmart` searches for an optimal position for windows, attempting to minimize overlap. The core of this algorithm tracks the
client's height and width in `ch` and `cw`, which have been adjusted by -1. This simplifies logic determining the bottom and right points of a
window when you are starting at the top and left points.
However, this decision requires adjusting that number by +1 when doing the opposite: determining the top and left points when you start with
the bottom and right points.
placeSmart cycles through window locations, searching for acceptable nooks and crannies to fit a window in, nicely. It begins by checking
for places to put the top left corner of the window which abut another constraint. If that fails, it then tries to place the bottom right
abutting a constraining feature.
After finding a suitable bottom (or right) location, the top (or left) location must be determined, requiring the -1 adjustment to be undone.
This patch adds that +1 back in.
# The bug it solves
This error can be seen by opening a bunch of windows that are placed using the "Minimal Overlapping" rule. The open space on the screen will be tiled from left to right, and then top to bottom in the windows. Once no more windows can be placed like that, the next window will be placed at the extreme bottom-right corner. However, it will be one pixel too low and one pixel too far to the right---if you try to move the window, it will "snap" to the correct spot.
This single pixel may seem minor or even irrelevant, but when you use the "Present Windows" desktop effect on a multiple-monitor setup, this one pixel will cause the window to show up on both monitors.
Pending buffers for drm planes and crtcs are no longer tracked in the planes
and crtcs themselves, but instead in a DrmCommit object that is used as
the user data for the pageflip handler. This way multiple commits can be
pending at the same time without causing conflicts, and the handling of
pending buffers is simplified as well.
This separate thread submits commits as late as possible, so that until
immediately before vblank the cursor position can still be updated, reducing
its latency and opening the door for more optimizations.
* speeds up incremental builds as changes to a header will not always
need the full mocs_compilation.cpp for all the target's headers rebuild,
while having a moc file sourced into a source file only adds minor
extra costs, due to small own code and the used headers usually
already covered by the source file, being for the same class/struct
* seems to not slow down clean builds, due to empty mocs_compilation.cpp
resulting in those quickly processed, while the minor extra cost of the
sourced moc files does not outweigh that in summary.
Measured times actually improved by some percent points.
(ideally CMake would just skip empty mocs_compilation.cpp & its object
file one day)
* enables compiler to see all methods of a class in same compilation unit
to do some sanity checks
* potentially more inlining in general, due to more in the compilation unit
* allows to keep using more forward declarations in the header, as with the
moc code being sourced into the cpp file there definitions can be ensured
and often are already for the needs of the normal class methods
There are use cases for the headers to be used, e.g. when implementing
wayland-specific workflows from an Effect.
In order to be able to use these, we also need to expose libkwin to be
imported as it carries the interfaces' symbols.

Static plugins being linked with shared libraries doesn't work smoothly.
POSITION_INDEPENDENT_CODE target property needs to be set for
every such plugin. However, there can be targets that we have no control
over, which need POSITION_INDEPENDENT_CODE to be set too. Asking such
projects to add this property and them refusing to do so would be
reasonable because kwin's entire static plugin pipeline is weird.
The test framework was made a shared library because kwin build
directory used to get really big (in 10s of gigabytes).
Due to the -fPIC issues, this change makes the test framework a static
lib again. Obviously, this brings back the big build directory problem.
But, it's not as terrible as it used to be. With this change, kwin build
directory is a couple of gigabytes in debug build, which is a lot but
not as bad as it used to be before.
The InputConfig was introduced to handle tests that don't have valid
kwinApp object. Those tests have been either reworked or dropped, so
let's drop the InputConfig to tidy the config stuff.
Interactions with KScreen cause settings to be reset to the default when the lid
gets closed, so handling lid closing in KWin needs to wait until KScreen no longer
writes configs
BUG: 471282
This change ports the drm backend to the GraphicsBuffer and
GraphicsBufferAllocator.
The main motivation is to unify graphics buffer abstractions across
various backends and to prepare it for output layers, which could be
nicer if we could have direct control over the buffers.
This change makes the EffectsHandler emit the windowAdded signal as soon
as the Workspace::windowAdded signal is received and minimize the
difference between the states observed in kwin core and effects.
The test is flaky. We work around it by passing --repeat until-pass, but
lately even it doesn't help us with this issue.
So skip the test when running it inside KDE CI for a few months until
it gets a newer kernel.
It makes decorations lighter as they don't need to bundle its
configuration logic.
Deprecates the kcmodule property in favour of kcmoduleName which instead
of assuming that the kcm is local to the plugin, it provides the plugin
name to find and load.
The Effects API has one signal screenEdgeApproaching with effects
monitoring the last signal to stay in sync.
If an Edge is destroyed whilst visible, effects currently do not get
notified and it can stay there forever.
This patch emits screenEdgeApproaching if appropriate with a factor of 0
when an edge is destroyed.

StrutsTest::testLeftScreenSmallerBottomAligned() used to pass because
one of the previous tests changes the maximize policy to maximize.
A window will be maximized only if it's larger than the maximize area
but smaller than the screen area. That's not the case and the test makes
an incorrect assumption about how X11Windows are placed.

Use CursorSource::image() instead.
Cursor caching in the ScreenCastStream has been changed so
QImage::cacheKey() is not being used. This is rather a preparation for
making kwin grab the contents of the cursor scene.
This change introduces InputDevice::pointerFrame(). The main motivation
behind it is to allow batching multiple pointer events within a single
event frame.
BUG: 454428
Qt requires xcb-icccm 0.3.9. On the other hand, 0.3.9 contains all the
types and functions used by kwin, so remove the corresponding
XCB_ICCM_FOUND checks to simplify the code.
The quick tile test waits 1s to ensure that the quick tile combine timer
is not active. On the other hand, if the active window changes, it makes
sense to reset quick tile combine status. That also lets us get rid of
the QTest::qWait() in QuickTilingTest::testShortcut().
The test used to verify that kwin doesn't crash when ShellClient sets
new geometry. ShellClient used to access decoration borders without
checking whether decoration() is null.
On the other hand, we've added a bunch of new test cases in
testXdgShellWindow, so let's remove this one. If the bug is back, that
test will fail.
This makes it possible to ensure type safety for enums, as each drm property
object can have its own type now, and it reduces the amount of typing needed
to access properties
The test needs OpenGL in order to ensure that the window view effect is
loaded and it registers a screen edge. On the other hand, we could
register a screen edge ourselves and thus allow running the test on
freebsd.
testXdgShellWindow already tests intricate subsurface size changes. The
surface pixmaps are handled differently now too, so the test is not
useful as it used to be 4 or 5 years ago.
Before Deleted merge, it used to be equivalent to waiting until the
window is closed.
This fixes tests waiting until the window closing animation completes
and the Window object is destroyed.
testPointerInput requires OpenGL compositing because it wants to test
cursor push back in the window view effect and the window view effect is
available only if OpenGL is supported.
On the other hand, ScreenEdgesTest::testPushBack() already tests similar
scenario, so let's drop relevant test in testPointerInput to allow
running it when using software rendering.
The virtual backend uses the surfaceless platform. On the other hand, we
move in a direction where the graphics buffer type is explicit, which
creates issues for the virtual backend.
This change ports the virtual backend to gbm so we could manually
allocate dmabuf buffers in order to unify buffer handling in kwin.
Its main drawback is that you won't be able to use the virtual backend
on setups without render nodes. On the other hand, given that the
compositor is meaningless without clients being able to share buffers
with it, it's reasonable to require some way to create and export prime
buffers.
WAYLAND_ONLY will create two tests: one with Xwayland, the other without
Xwayland. This is somewhat wasteful and it results in higher CI times.
On the other hand, Xwayland is started on demand. If a test doesn't need
Xwayland, it won't start.
So let's remove WAYLAND_ONLY in order to lighten kwin on CI resources.
If wayland only tests are needed, we can consider passing the operation
mode to the WAYLANDTEST_MAIN helper, but there aren't such tests afaik.
Window::desktop() is obsolete. On the other hand, X11 doesn't support
having a window on several virtual desktops, so we still need it. As a
compromise, this change moves it to X11Window instead.
Currently, managed and override-redirect windows are split in two types:
X11Window and Unmanaged. While looking at it strictly from type
perspective, this is great. But it creates other problems, e.g. we need
to put shared X11-specific code in the base Window class or mess with
"base" classes.
As an alternative solution, this change merges the Unmanaged class into
the X11Window class and disables some functionality based on the value
of isUnmanaged().
X11Window::manage() is used to create a managed Window. X11Window::track()
is used to create an unmanaged Window.
Currently, the normal window lifecycle looks as follows: create Window,
wait until it's shown, add it to Workspace, wait until it's closed,
create a Deleted, copy properties from the original window to the
deleted one, destroy the original window, wait until the last deleted
window reference is dropped.
There are a couple of issues with this design: we can't nicely
encapsulate X11 or Wayland specific implementation details if they need
to be accessed for closed windows; manual copying of properties is
cumbersome and error prone and we've had a dozen of cases where effects
worked incorrectly because some properties had not been copied.
The goal of this patch is to drop Deleted and extend the lifetime of the
original window, but with a special state set: Window::isDeleted().
The main danger is that somebody can try to do something with deleted
windows that they should not do, but on the other hand, such code needs
to be guarded with relevant checks too.
Workspace::outputAt() casts vectors to four rectangle corners and uses
the shortest one to decide which output is the closest to the given
point.
This works poorly on dual monitor setups where on the left side you have
a monitor with landscape orientation and one with portrait orientation
on the right hand side. In that case, outputAt() will prefer the left
monitor even though the right monitor is the closest one if you cast a
perpendicular from the given point to the right monitor.
In order to improve the handling of that case, this change makes
Workspace::outputAt() compute the closest point to the output geometry
rectangle and use the squared distance as the score.
The indirection contributes unnecessary complexity. The usage of
std::weak_ptr and std::shared_ptr complicates the things further, e.g.

Ideally, same should be done with TabBox and TabBoxHandler, but that can be done in another MR.
Tabbox supports two operation modes: switching between windows and
desktops. Switching between windows is more commonly used. Desktop
switching is not exposed in user settings and it requires some advanced
knowledge of kwin's internals to enable it.
On the other hand, over the past years, we've double downed on effects
like desktop grid and overview to provide graphical means to switch
between virtual desktops.
This change drops desktop switching because it's effectively unused to
simplify the tabbox code, which can be very handy for the future
refactorings of window switching.
Currently windows are scattered in a few separate lists. If you need to
go through the windows, you have to do it piece by piece. On the other
hand, with the overhaul of window types, we've started converging
towards one universal type: Window. Keeping windows in the separate
buckets goes against this design.
Workspace::stackingOrder() already contains all windows. This change
repurposes Workspace::allClientList() from a list of "normal" windows to
all windows, i.e. Workspace::windows(), to be consistent.
There's one API change though. Scripting API will expose other window
types too. This is an intentional change so scripted effects could
operate with all windows. It also matches the current behavior observed
in libkwineffects, which exposes all windows as well.
Instead of having every DrmProperty store pending values, store the data
for the next commit in a separate and temporary type. This simplifies the
code and makes it possible to do commits in a separate thread
Currently Deleted are destroyed with a delay to avoid dangling pointers
within the middle of painting.
On the other hand, it's reasonable to require not to delete windows when
kwin starts painting the screen.
Over the years, we refactored how deleted windows. They are always
unreferenced after finishing the current frame. So it should be fine to
destroy Deleted immediately now.
Qt::AA_UseHighDpiPixmaps has no any effect now.
We used to rely on the fact that Qt::AA_UseHighDpiPixmaps is disabled by
default in Qt 5 in kwin_x11. It's not clear what to do about it now.
It doesn't test anything useful. It's hard to make it test useful things
too due to needing to change the system time. Linking with it also
breaks the encapsulation and it won't work when using MODULE library.
