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.

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.

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
The order in which Xwayland surfaces are associated with X11 windows is
undefined, meaning that we cannot assume that a newly created X11 window
won't have a surface associated with it already.
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.
