For some reason, while touch doesn't have a middle button, the
taphandler for middle click close still triggered on tap. So make it
explicitly only support mouse/pen so we exclude touch events.
BUG: 445755
For many windows it will be invisible, so there's little point for
creating it ahead of time. Another reason for loading the close button
on demand is that Plasma components are typically heavy.
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.
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().
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
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.

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.
After user edits the name of a desktop, the search field is no longer
focused. If the user starts typing text, one could expect that it will
be forwarded to the search field without requiring a click.
This change forwards unhandled key events to the search field to ensure
that searching is intuitive.
Since binary effects are installed in their own directory, checking
service type is redundant. Also, KPluginMetaData::serviceTypes() has
been deprecated.

The role of enabledByDefaultMethod was misinterpreted. It exists only
for kcms so they can display undetermined state. EnabledByDefault should
still be set to a valid value.
For optimization purposes, kwin will ignore repaint regions scheduled by
invisible windows, e.g. hidden docks, minimized windows, etc.
The problem is that it sort of breaks w->addRepaintFull(). If a lot of
animation frames are dropped, for example due to heavy cpu load, the
sliding popups animation can jump from the middle of animation right up
to the end. It will schedule a repaint but it will be ignored.
In order to work around that issue, this change makes the sliding popups
effect schedule workspace repaints in postPaintScreen() to ensure that
the Scene will always repaint dirty regions.
Hopefully, this should fix bugs where auto-hide panels sometimes flicker
on Wayland.
BUG: 444502
The screen count can be retrieved by checking the number of items in the
EffectHandler.screens property.
The replacement for the numberScreensChanged signal are the screenAdded
and the screenRemoved signals.
The main motivation behind this change is to clean up the screens api
and reduce the number of usages of the Screens class.
This provides a way to create, destroy, and rename virtual desktops in
the overview effect as well as switch between desktops.
The mechanics of switching between virtual desktops can be revisited
later though.
Linking builtin effects against KCMs is really awkward. This change
decouples builtin effects from KCMs that use EffectsModel.
In order to discover builtin effects, metadata files are installed in
kwin's data dir, which will be subsequently read by EffectsModel.
The main motivation behind this change is to prepare kwin for importing
kwayland-server code in libkwin.
As is, builtin effects are linked with libkwin. Some builtin effects
have wayland specific code. If we move wayland stuff in libkwin, there's
going to be a circular dependency between kwin4_effect_builtins and
libkwin targets.
This change intends to break that dependency by linking builtin effects
to kwin executable.
The main issue with that is that EffectLoader would need to discover the
effects indirectly. QStaticPlugin is used for that purpose.
Besides breaking the cyclic dependency, it makes builtin effects use the
same plugin infrastructure in libkwineffects that external effects use.
Metadata in src/effects/effect_builtins.cpp was converted in a list of
python dictionaries, which was fed to a python script that generated
main.cpp and metadata.json files.
As is, libkwineffects doesn't use any specific apis in kwayland-server,
it simply "forwards" wayland display and surfaces from libkwin. Given
that, there is no need to link libkwineffects with kwayland-server. If
an effect needs to access wayland specific stuff, it can link explicitly
against kwayland-server.
The main motivation behind this change is to further loosen up
dependencies between various kwin components and kwayland-server so the
latter can be moved back to kwin.
Currently, cpp source files are included partially in effect sub-folders
and src/effects/CMakeLists.txt, which is really confusing and hard to
follow.
With this change, effect targets will be defined in their own subfolders.
This makes build files more straightforward.
Effect sub-targets are eventually merged into a monolithic
kwin4_effect_builtins target.
Another reason for modularizing builtin effects is that no two effects
can generate moc files with the same name atm even though they are in
different sub-folders. This can be potentially useful in the future, e.g.
making effects static plugins in order to decouple builtin effects from
libkwin (every effect subfolder would need a main.cpp or plugin.cpp file,
which will include the associated moc file).
The GLTexture class is forward declared and the ShowFpsEffect class has
a QScopedPointer<GLTexture> field. We either need to include the
kwinglutils.h header file or add a destructor that does nothing and
define it in the cpp file, where kwinglutils.h is included.
clientArea() was changed to forbid "-1" screen ids, but it seems like
the thumbnail aside effect can pass it to refer to the active screen.
This change makes the thumbnail aside effect handle "-1" screen id case
explicitly. It will be also useful for EffectScreen transition.
BUG: 443166
ksmserver provides the backing window (the hidden black one) for the
lockscreen. We don't want to animate this fading out.
It no longer provides the logout prompt since several plasma releases.
This makes ExpoLayout easier to maintain. As is, the main issue with it
is the number of layout algorithms.
With this, the ExpoLayout is going to have two layout algorithms - one is
very simple and the other not so.
With per-screen rendering, the projection matrix is no longer created
with the workspace geometry, i.e. all screen geometries united, so the
center of the workspace geometry may not map to (0, 0) in the clip
coordinates.
GLRenderTarget::virtualScreenGeometry() can be used to query the rect
that was used to create the projection matrix.
BUG: 442770
Removing (WIP) will result in more work for translators. There are other
ways to indicate the effect is not ready for its prime time yet, e.g.
being disabled by default.
The present windows allows the user to search windows by their caption
or window role. This change brings that functionality to this effect.
BUG: 441302
The previous implementation added noise in linear space, which resulted in
the effect becoming more pronounced on black backgrounds. This patch
changes the process to be applied in perceptual space, by making the noise
addition pass a separate draw call and disabling GL_FRAMEBUFFER_SRGB during
that.
After this change, noise will look much more suppressed and almost never
grainy. This change also changes the range of the noise from
[-strength..strength) to [0..strength), as blending can only be either
additive or subtractive. As a result, users might need to ramp up their
noise parameter after this change.
v2: Add more explanation around the draw call.
v3: Fix noise not fading out with the fade out effect.
v4: Restore an accidentally removed comment.
v5: Add CCBUG.
v6: Rebase.
v7: Fix a formatting issue.
CCBUG: 409620
