Ensures that m_active and the input context do not get out of sync and
that the right signals are always emitted by always using setActive to
activate.
Uses the context to define InputMethod::isActive.
Detach from the serials that the client send us, since they don't really
matter to the input method and track our own.
Also issue a commit state whenever we adopt a new input context. This
can happen for reasons that don't come from the client, like for example
the input method has just been enabled.
In practice, this solves an issue that we can easily see with maliit
where it would be left in a half-initialised state and would show
autocorrection fields on terminal applications when unnecessary and
possibly similar problems every now and then.
The current UI allows to remove the last desktop, but:
- If you remove it it will reappear on the next KCM launch
- The Add button does not work then
Prevent removing the last desktop by disabling the action
BUG: 437561
When the user applies a change like adding a desktop
DesktopsModel::syncWithServer is called and m_synchronizing is set to
true. The server then sends some kind of response (e.g. desktopCreated)
and updateModifiedState is called which sets m_synchronizing to false
again.
However if a setting is changed that does not trigger any server change
(e.g. the show OSD setting) m_synchonizing is never set to false again,
causing problems down the line.
Instead of relying on updateModifiedState to reset m_synchronizing track
the syncronizing state by refcounting the DBus calls

Not choosing any virtual keyboard is a valid option. In this case do not show the SNI since it isn't very useful then and takes up some space in the system tray.
BUG: 437171
Most distros use either systemd's logind or consolekit for session
management.
The main reason why there's direct session is because up to some point,
kwin had a class called VirtualTerminal which was kind of like a direct
session backend.
The VirtualTerminal was used in the fbdev backend in conjuction with the
logind session backend, which looked odd.
Since the drm backend supported only logind and consolekit for very
long time and we hadn't received any complaints about it, the fact that
direct session is unsupported should not be noticeable.
Given that, this change removes the support for direct session in order
to reduce the amount of platform-specific code and make it easier to
maintain kwin.
Currently the apply button will only be enabled when you press enter or
change focus away from the text field which is somewhat inintuitive.
Instead enable the apply button as soon as the text changed.
BUG: 435014
With high DPI we can't use the image size as a logical size directly.
The other change is use of QPainter::drawImage(QRect target, QImage
image, QRect source)
This slightly confusing method uses logical pixels for the target, but
the source rect is in native pixels of the source.
BUG: 422342
If the egl backend gets deleted this leaves a dangling pointer. In
order to prevent crashes with QPainter or EglStreams also don't try
to create dmabuf textures without a EglGbmBackend.
One can think that Item::scheduleRepaint() will trigger repaint of the
whole item, but it actually only schedules the next frame. If nothing
has changed on the screen, no real painting will be done unless maybe if
the rendering backend needs to repair the back buffer.
They are used only by X11Client, so make X11Client call relevants
methods on the surface item directly instead. In hindsight, it will be a
really good idea to make SurfaceItemX11 and SurfaceItemXwayland(?)
automatically manage the window pixmap. However, it can be done once
an item freezing api is added and we fix the cross-fade animation.
Currently, items depend on scene windows for creating pixmaps, repaint
scheduling, and caching quads.
This change moves repaint scheduling from scene windows to items to
make the scene items depend less on scene windows.
In hindsight, we may clean up the repaint scheduling machinery further
by introducing view objects.
So far we had a composition setup within kwinrc and kscreen. This
produces flickering sometime and makes the state a bit more flimsy.
This patch changes the kwin's behaviour to use the files produced by
kscreen which are anyways available down the line.
THis simplifies our behaviour down to just one format that we write to
and feed from. This also allows us to leverage it further by using this
format for default setups (which consist in the right file in
~/.local/share/kscreen).
With the introduction of scene items, the Scene::Window::bufferShape()
method was removed as it makes no sense on wayland - a window may have
several sub-surfaces, so a single region to indicate the shape of the
window won't work.
SurfaceItem::shape() returns the shape of a surface. On Wayland, it
corresponds to the rect of the wl_surface. On X11, it corresponds to the
client window rect inside the frame window, or custom shape region if
the client has set one.
On the other hand, EffectWindow::shape() wants a completely different
thing. If the window is decorated, it needs to return the rect of the
decoration. Otherwise it has to return the shape region if there's one.
In the future, the EffectWindow::shape() function must be removed as it
doesn't fit the item based design. The main reason why we have it at
all is because the x server doesn't support translucency, setting a
shape region is a (hacky) way to work around that limitation, xeyes is
a notable example.
BUG: 437138
BUG: 435862
One of the scene redesign goals is to make wayland surface items
re-usable. So we have the same rendering path for drag-and-drop icons,
software cursors, and window surfaces.
The biggest issue at the moment is that window pixmaps are tightly
coupled with scene windows.
This change de-couples window pixmaps from scene windows. In order to
achieve that, some architecture changes were made.
The WindowPixmap class was replaced with the SurfacePixmap class. A
surface pixmap is created by a surface item.
Under the hood, a SurfacePixmap will create a PlatformSurfaceTexture
object, which contains all the information necessary for the renderer.
The SceneOpenGLTexture class was removed. However, the GLX and the EGL
on X11 backends still mess with GLTexture's internals.
The Toplevel::clientContentPos() function is needed to map the surface
local coordinates to the global coordinates. But its name is highly
confusing as there's already a function with a similar name. This change
introduces a helper with a better name to fix the readability issue.
This is to improve code readability and make it easier to differentiate
between methods that are used during interactive move-resize and normal
move-resize methods in the future.
This makes the implementation of the buffer geometry consistent with the
frame geometry and the client geometry and removes a virtual method call
from a few hot paths.
We need to emit the clientFinishUserMovedResized signal to notify
effects such as translucency that the interactive move-resize is
finished. Otherwise, the set() animation won't be cancelled and the
window will get stuck frozen.
BUG: 409376
As is, kwin with the drm backend results in the most pleasant user
experience on Wayland. Given that and the fbdev being about to be
dropped, making libdrm a required dependency seems a reasonable decision.
Many reasons have been brought up over the years for why this effect is
not appropriate to be enabled by default:
- It was designed to highlight the whizzy technical feature of being
able to make windows transparent, which is no longer particularly
impressive today.
- It looks visually dated.
- It can produce a confusing visual soup by blending a window being
moved or resized with the content below it, which we recently disabled
for the Highlight Windows effect.
- If one window is covering up another as a way to deliberately hide the
content of the lower window, this effect will reveal the hidden
content whenever the upper window is moved or resized at all.
Overall it does not seem to have enough advantages to offset these
issues. Let's disable it by default--but only for the people who did not
modify its configuration at all. We can assume that those people like
it, so let's keep it on for them.

It's needed to make kwin_wayland properly systemd managed. A service
launched using systemctl --user is per user, not session.
As a consequence, user services run outside the session. Applications
that deal with user session need some quirks to work with systemd boot.
Unfortunately, GetSessionByPID() doesn't work well with systemd boot,
see bug 433364. GetSession(auto) is shown to work better.
With the client-side decoration changes, kwin will properly determine
whether the window needs to be configured even if the frame geometry has
not changed.
This change slightly changes the semantics of the setFrameGeometry()
method. Prior to this, it was possible to force a geometry, i.e. block
other geometry updates, however such a behavior is counter-intuitive and
it exponentially increases the complexity of code.
As far as I know, the force flag was needed to propagate geometry
changes if the frame geometry doesn't change, but the client geometry
does. With the client-side decoration changes, the force flag is not
needed, as kwin now takes into account the client geometry and the frame
geometry when determining whether to send a configure event.
If a minimized window is animated by the AnimationEffect, the final
layer repaint will be ineffective. In order to account for that, the
AnimationEffect adds the layer repaint to data.paint in the
prePaintScreen() hook. The issue with this hack is that it does not
work on Wayland with per screen rendering.
If a window is animated on screen B, but the layer repaint is added
to data.paint when screen A is painted, there will be a ghost of the
window on screen B.
In order to fix this issue, we need to use effects->addRepaint(), but
we cannot use it in prePaintScreen() as it won't have immediate effect.
effects->addRepaint() can be called either from window paint hooks
or from the postPaintScreen() hook. This change goes after the latter
option.
In the prePaintScreen() hook, AnimationEffect will only advance
animations. In the postPaintScreen() function, it will perform final
janitorial chore.
The internal EventQueue is a child of the registry object. This means
that after the registry is destroyed, all proxy objects in that event
queue are going to have invalid reference to it, which is not a problem
as long as the wl_display_dispatch() function is not called.
The wl_display_dispatch() function uses wl_proxy's queue reference to
enqueue incoming events to that queue.
Unfortunately, during teardown, the internal ConnectionThread may
dispatch events right after the registry object has been destroyed,
which can lead to a crash.
In order to fix the crash, we need to destroy all proxy objects and only
after that we can destroy the event queue. It's okay if wayland events
are dispatched in between.
This allows Task Switcher visualizations to know whether compositing is
active or not so they can adjust their visual representations
accordingly, if needed.
This reverts commit 110182b213.
The reverted commit has introduced a regression where interactively
moved windows jump back to their old position. This needs some time for
proper investigation. Due to beta rolling out quite soon, it will be
better to revert the change.
Rather than have an error prone way to detect whether a configure event
has good position information, handle the case where the plasma shell
surface has a position hint explicitly.
On X11, the lockscreen greeter is an override-redirect window so the
scale and the glide effect ignore it.
On Wayland, the lockscreen greeter is a regular window so both effects
try to animate it upon the screen being unlocked, which looks bad.
So far we were only tracking the first touch point, meaning that if 2
touch points were applied to the internal window and removed one, the
second's events would then be sent to Wayland, which would assert since
it didn't know it had been pressed in the first place.
This fixes InternalWindowTest::testTouch
We want panels to be behind fullscreen windows, but osd windows above
them. With the current layer promotion logic, the panel will be promoted
to the osd layer, which is undesirable. This change restores the old
behavior by allowing layer promotion only to ActiveLayer.
BUG: 436985
It's inherited by XdgToplevelConfigure and we need to make sure that the
object gets destroyed properly.
Alternatively we get a new-delete-type-mismatch error in ASAN and
rightfully so.
Workspace::constrainedStackingOrder() is a constant source of issues.
This change replaces the current logic that builds the stacking order to
hopefully make constrainedStackingOrder() less crashy.
With the new version, constrainedStackingOrder() doesn't perform layer
caching. On the other hand, it's quite rare to see apps in the wild that
have more than just 1 or 2 members in the window group.
BUG: 436095
Currently, the Workspace has no any api to constrain one window above
another. This results in having hacks such as keepDeletedTransientAbove()
This change introduces a basic api to constrain a given window above
another. It can be used for ensuring that transient windows are placed
above their parents. It also can be used for stacking the outline window
below the move-resize window.
Internal windows may also have transient parents. Because of that, this
change makes the workspace add internal clients to the stacking order by
default. The good thing about it is that it allows us unify some input
related code for "external" windows and internal windows.
According to the HIG, the InCubic easing curve should be used if the
animated item changes its state from visible to invisible and the
OutCubic easing curve if vice versa.
This feature was implemented in commit a66eb1a5b9 earlier
Double tap wake up is not a feature to be implemented at compositor
level but rather at the hardware/kernel level. Double tap timer here
means when screen is turned off, libinput will continue to poll the
touchscreen for new events.
double-tap-to-wakeup is generally interrupt at driver/hardware level
which have ability to wake system up even from the sleep.
Provide a option to disable the double tap timer on kwin side for
devices which makes use of suspend since when in suspend kwin can not
wake device up, and that provides confusing user experience.
This micro optimization is simply not worth having. raiseOrLowerClient()
is not in any hot path, besides that raiseClient() is not the only place
where a window can be raised above other windows. In addition to that,
the most_recently_raised check in raiseOrLowerClient() doesn't take into
account whether the cached window is on the current activity.
SurfaceItemInternal will discard the current pixmap if the buffer size
changes. Also, one of the goal of the scene redesign is to keep things
such as this out of Toplevel subclasses.
When the maximize mode changes from MaximizeFull to either
MaximizeHorizontal or MaximizeVertical, (max_mode & MaximizeFull) will
evaluate to true because MaximizeFull is defined as bitwise OR between
MaximizeHorizontal and MaximizeVertical.
