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.
Commit 88cf8355 changed the behaviour of Mali (Lima) / PinePhone devices by disabling GLSL
88cf8355 got backported in 5.27.1 and broke PinePhone devices (White rectangle on topright quarter of a black screen)
This patch restores the behaviour of 5.27.0
VirtualDesktopManager::currentChanged() can be emitted with
previousDesktop being null/0. It can happen only on startup. After that,
it's always valid. In order to make the code that uses the
currentChanged signal less trickier, ensure that the current virtual
desktop is initialized when the virtual desktop config is loaded.
This merges Window::clientMinimized() and Window::clientUnminimized()
signals with the Window::minimizedChanged() signal to simplify some
code.
The avoid animation flag has been dropped because its main usage is to
avoid playing animation during window initialization. But it's not possible
to trigger minimize animation at that moment. API-wise it's better to avoid
having such flags too and rely on surface role to decide whether to play a
given animation.
This signal exists as a convenience helper, but it's not always emitted
as it's advertised to work. Instead of fixing it, let's drop the signal
to simplify virtual desktop code. Its effects can be accomplished by
monitoring Window::desktopChanged() and VirtualDesktopManager::currentChanged()
signals in effects and scripts where needed.
Checking if the pointer needs to be confined before doing `std::clamp` on
the position is useless and causes problems. With this change, the pointer
will always be confined to exactly the screen, without any fractional offsets.
BUG: 461911
Use input device specific apis to change the position of the cursor. The
main reason to do so is to break the assumption that Cursor position is
the same as pointer position, which I would like to rely on later to
merge tablet and pointer cursors.
Even though the names seem to match, QtWayland maps button values
to enum values in ascendung order (as it does on X11). The wrong
mapping is usually not a problem because we send the native button
events to clients. However when the Qt names or values are used
for communication between KWin and a client this leads to
misunderstandings.
BUG:465463
FIXED-IN:5.27.1
This installs a socket notifier onto our xwayland socket, when a user
connects we launch xwayland. The client then connections once kwin has
established itself as the compositor.
For a full desktop plasma session this patch effectively does nothing
too useful as we still start kcminit and make xrdb calls on startup
which in turn will launch X, but for the same reason this patch should
be harmless now as we're still processing the xrdb calls before any
clients will connect.

testLockScreen uses !eventSpy.wait() expression to check whether the

which is too much. We don't need to wait that much, in fact, even

* Allow to do quick tiling to custom tile geometries, windows will be snapped to tiles when dragged with the shift modifier pressed.
* Tile geometries are screen specific.
* The global shortcut Meta+T will trigger a fullscreen configuration ui as a QML effect for the tiles which allows to add, remove and resize tiles
* UI and behavior is a bit similar to the Windows Fancy Zones addon: https://docs.microsoft.com/en-us/windows/powertoys/fancyzones
* Its main scope is to help the workflow with very big monitors, especially ultra wide ones, where most application don't make sense maximized to the full screen (eventually also support games to be full screened to a given tile instead of the whole screen)
* it should get also some bindings for scripting, as its ain goal is not to replicate other popular tiling window managers, but should give the popular kwin tiling scripts to have a more robust infrastructure
* it will eventually get support for a set of predefined layouts, but this is for a second phase
BUG: 438788
We use KWIN_NAME, KWIN_INTERNAL_NAME_X11 and KWIN_INTERNAL_WAYLAND
properly only in a few places. In other, we use hardcoded names.
Let's not bother and hardcode kwin names everywhere rather than have one
foot in and one foot out, it's simpler.
Due to being a compositor, kwin has to conform to some certain
interfaces. It means a lot of virtual functions and function tables to
integrate with C APIs. Naturally, we not always want to use every
argument in such functions.
Since we get -Wunused-parameter from -Wall, we have to plumb those
unused arguments in order to suppress compiler warnings at the moment.
However, I don't think that extra work is worth it. We cannot change or
alter prototypes in any way to fix the warning the desired way. Q_UNUSED
and similar macros are not good indicators of whether an argument is
used too, we tend to overlook putting or removing those macros. I've
also noticed that Q_UNUSED are not used to guide us with the removal no
longer needed parameters.
Therefore, I think it's worth adding -Wno-unused-parameter compiler
option to stop the compiler producing warnings about unused parameters.
It changes nothing except that we don't need to put Q_UNUSED anymore,
which can be really cumbersome sometimes. Note that it doesn't affect
unused variables, you'll still get a -Wunused-variable compiler warning
if a variable is unused.
Makes it possible to follow the dbus service for locale configuration,
making it possible to have third parties integrate with Plasma.
This is done opt-in for now, it can be adopted generally in the future,
if necessary.
The entire approach behind that test is wrong. Even slight changes in
one pixel can make the test fail. There's no human-friendly way to
determine what the difference between reference and actual frames are.
The reference frame is generated in code rather than from an image on
the disk, which makes the tests even more error-prone.
The test is flaky too and constantly blocks merging patch submissions.
We need a different way to test rendering results, not what
testSceneQPainter currently does. Normally, I would say that we need
to add such an infrastructure before dropping the test, but it makes the
merging process so inconvenient and the test doesn't really bring any
value, it tests really basic cases which are noticeable right away after
launching kwin.
With the addition of KGlobalAccel::globalShortcutActiveChanged(),
there's a way to monitor all triggered actions without adding any
boilerplate code.
This change removes the KGlobalAccel bits from the Platform class. This
reduces the amount of boilerplate code; currently we need to be careful
about ensuring that Platform::setupActionForKGlobalAccel() is called.
Another reason behind this change is to simplify the api of Platform and
remove things that don't have anything to do with outputs.
Use isNull on QSizeF to check for a zero delta instead of comparing it
with a default-constructed QSizeF, which in practice initializes to
(-1.0,-1.0). This caused relative motion events to be omitted if the
delta happened to be equal to (-1.0,-1.0), causing mouse jumping in some
applications.
BUG: 444510
Signed-off-by: John Brooks <john@fastquake.com>
The signal will be emitted if text-input-v3 applies a new enable state
if it's already enabled.
In Gtk's implementation, sending text_input_v3.enable for the second
time has the similar semantics of text-input-v2.showInputPanel. Try to
connect them together and add corresponding test.
See also: a95cfb1c45/gtk/gtkimcontextwayland.c (L555)
Writing is what our guard is supposed to prevent, let's try to mmap it
for writing. It seems FreeBSD still allows PROT_READ for sealed-for-writing
mmaps.
When text input gets enabled, the sequence should be
1. enable
2. request to show the panel
3. panel gets added and shown
And showing the panel again after hiding is an important case to cover as
well.
QXkbCommon fails to map `Ё` to `~` when pressing `Shift+grave` and
sequenceEdit seems to have focus now.
On the other hand, does it make sense to bind global shortcuts with key
sequences such as "Shift+`"? The system settings doesn't even allow typing
in such key sequences.
testDbusInterface fails with Qt 6 build because QCOMPARE detects the
type difference between QString and QByteArray.
Since these properties being byte arrays has caused reasonable amount of
discomfort, let's make them QStrings. It will fix the test and make some
scripted effect code more cleaner.
PointerInputTest::testWarpingBetweenWindows() compares
QVariant(QPointF) with QPoint. While this works in Qt 5, Qt 6 seems to
take the type into account when comparing the two.
TestXdgShellWindow::testPointerInputTransform() compares
QVariant(QPointF) with QPoint. While this works in Qt 5, Qt 6 seems to
take the type into account when comparing the two.
In some cases, stateCommitted may fire after a new surface being focused
and in correctly set input method to be inactive. This can be reproduced
by switch client between an active text input v3 client and text input
v2 client.
The Workspace requires at least one output and no output has 0x0 size.
This fixes a crash in confineToBoundingBox() where qBound() asserts that
the min value is less than the max value, in our case the x coordinate
of the left edge of the workspace is less than the x coordinate of the
right edge of the workspace.
