This change moves some pieces of the Overview effect in a new
QuickSceneEffect class that can be useful for other QtQuick based
effects.
The QuickSceneEffect class is meant to deal with rendering bits, input
handling, etc.
As the user of the QuickSceneEffect class, you need to override the
createView() method. The createView() method is invoked by the
QuickSceneEffect when it wants to create a QtQuick scene for the given
screen.
The design of the QuickSceneEffect is based on the Overview effect.
EffectQuickScene is not used strictly by effects, aurorae decorations
use it too to render window decorations.
This change renames the EffectQuickView/Scene to
OffscreenQuickView/Scene to clear up the naming scheme.
Add `tabletToolEvent()` to DecorationEventFilter class so it can handle
tablet events.
Add `tabletToolEvent()` to MoveResizeFilter class to avoid incorrect
titlebar highlight after a window is resized by using a stylus.
Add `tabletToolEvent()` to WindowActionInputFilter class so window focus
can be changed by clicking on the window content area when using a stylus.
Add `update()` to `TabletInputRedirection::tabletToolEvent()` to enable
switching window focus by using a stylus.

This prevents flickering behind plasma panels after changing compositing
settings.
If the contrast effect is disabled, the destructor of the ContrastEffect will
start the contrast manager remove timer. When it expires, the contrast manager
global will be removed and it will be finally destroyed after 5s (to work
around the wl_global race condition).
If compositing is toggled, the destructor of the ContrastEffect will start
the remove timer and the constructor of the ContrastEffect will stop the
timer, the contrast manager object will be unaffected.
The contrast effect has no options that could affect the shader, so the
reconfigure() method was removed.
This prevents flickering behind plasma panels after changing compositing
settings.
If the blur effect is disabled, the destructor of the BlurEffect will
start the blur manager remove timer. When it expires, the blur manager
global will be removed and it will be finally destroyed after 5s (to work
around the wl_global race condition).
If compositing is toggled, the destructor of the BlurEffect will start
the remove timer and the constructor of the BlurEffect will stop the
timer, the blur manager object will be unaffected.
The blur effect options don't affect the generated shader code, so the
shader status check was removed in reconfigure().
This enables kwin to get notified when a memory has been lost in the
system, allowing the driver to purge all the memory and have kwin create
new contexts.
This matches what we do on GLX.
The current code for creating the root shared context is very naive and
does not take into account aspects like robustness or versions.
It is not always possible to mix attributes, in particular robustness
meaning we are unable to opt into these features in future contexts.
This refactors everything to use a common path to make all contexts.
In the KPluginSelector we don't have the possibility to set the args for
each KCM. Because of that we use the metadata of the KPluginFactory as a
fallback to read the plugin keyword, which specifies the KCM we want to display.
This requires kcmutils 54b196a9bad88732debe0b49111af4755268f09f, which landed in the last release.
BUG: 445667
The person that added krunner search integration uses vim. It seemed
intuitive to that person that the Escape key should quit the search mode
instead of quitting the effect. But it seems like more intuitive thing
is to actually stop the effect.
BUG: 445708
If the opacity property is set to 0, the item will still receive mouse
events. One either needs to set the enabled or the visible property to
false to ensure that the WindowHeap receives no mouse events.
The reason for setting the opacity to 0 instead of the visible property
to false was that I thought later will nuke the paint node, but it seems
like that's not the case.
BUG: 445707
This is needed to ensure that mouse release events go to the view that
received mouse press events; otherwise some views can get stuck in a
state thinking that button xyz is pressed.
Currently, cursor shape set by QtQuick is not sync'ed, which can be seen
as the pointer not changing its shape to i-beam when hovering the search
field.
Currently, every time you launch the overview effect, QtQuick will go
out and parse QML files. With the overview effect gaining more features
and the code size getting bigger, it takes more time for the overview to
present the first frame after it got triggered.
With this change, the overview effect will keep the ScreenView
QQmlComponent object around that can be used to avoid reparsing qml code
every time the overview effect is launched.
It also ports the Overview effect from de-facto deprecated qml context
to initial properties, which yield slightly better startup times.
BUG: 445666
This allows effects to support touch input.
Unfortunately, Qt's TouchEvents require the full touch point state,
whereas KWin's internal touch handling only deals with one point at a
time. So we need to keep track of the touch state in EffectQuickView and
pass that on to Qt. Additionally, we need a QTouchDevice as lots of Qt
code depends on it.
On my Nvidia machine there was a massive lag exitingthe overview effect.
Hotspot showed it as being in QOpenGLVertexArrayObjectPrivate::destroy.
In this method we clean up some shared objects used in the context when
the context closes.
In order to do this we need the context to be current. If it is not
current Qt currently internally creates a temporary offscreen surface.
To fix this we need to have our context current during destruction,
which includes changing order so it is destroyed before the surface.
With this change, user will be able to press Tab and use Enter, Delete,
and F2 keys to activate, remove, and rename virtual desktops, respectively.

If a window wants to be initially shown in fullscreen mode, it will
issue an xdg_toplevel.set_fullscreen request before the first surface
commit.
If a window wants to be shown in fullscreen mode and there hasn't been
any first surface commit, kwin will cache the request and apply
fullscreen mode when checking window rules in the initialize() function.
On the other hand, window rules are disabled for plasma surfaces. The
motivation behind that was to forbid user from messing with plasma's
surfaces (this change was suggested during redesign of xdg-shell
implementation).
As it turns out, there are cases where plasma may ask to show a window
in fullscreen mode, which also has a plasma surface installed, e.g.
fullscreen application dashboard.
In order to fix the dashboard, this change allows window rules to be
applied to xdg-toplevel windows that also have plasma surfaces installed.
As is, xdg-toplevel surfaces and plasma surfaces are very different in
nature. Adding more quirks to handle plasma surfaces in
XdgToplevelClient is not worth the effort and there are better
alternatives, e.g. layer-shell.
Based on user feedback, it will be great to have krunner functionality
integrated in the overview/present windows effect.
This change ports the overview effect to Milou for search results. With
it, one can search for existing windows or launch new applications.
BUG: 445207
kwin-strip-effect-metadata needs to run on the host. First, one needs to
build it, e.g.
cmake --build build-native --target kwin-strip-effect-metadata
then when cross-compiling, point cmake to the native build directory, e.g.
cmake -DKWIN_HOST_TOOLING=${path}/build-native
This improves plugin loading times. As is, the main issue is the number
of builtin effects and the fact that each has a lot of translated
strings, which combined adds up to noticeable loading times. KWin itself
will never read those translated strings, it only needs two pieces - the
plugin id and whether the plugin is enabled by default.
This change adds a little helper to strip unnecessary info from metadata
files.
Fixes a crash I have with dpms + suspend, which was caused by the udev
event for updating outputs being called before the output got enabled
again. When DrmGpu::updateOutputs got called it removed the crtc from
the inactive output and then disabled the output afterwards. Instead,
only remove crtcs if an output is really disabled.
This also allows to generalize the logic for lease outputs, and could
in the future allow for faster dpms on/off switching.
