AbstractOutput is not so Abstract and it's common to avoid the word
"Abstract" in class names as it doesn't contribute any new information.
It also significantly reduces the line width in some places.
Input event flow has been refactored so all input events originate from
input devices.
The X11 backend uses InputRedirection so make it forward events to
relevant input device handlers.
GLRenderTarget doesn't provide a generic abstraction for framebuffer
objects, so let's call GLRenderTarget what it is - a framebuffer.
Renaming the GLRenderTarget class allows us to use the term "render
target" which abstracts fbos or shm images without creating confusion.
Using the global coordinate system when specifying output layer damage
regions would be very confusing. In order to make the coordinate system
comprehensible, use the layer-local coordinate system.
The infinite region is used to tell the Compositor when it needs to
repaint the entire layer.
The .clang-format file is based on the one in ECM except the following
style options:
- AlwaysBreakBeforeMultilineStrings
- BinPackArguments
- BinPackParameters
- ColumnLimit
- BreakBeforeBraces
- KeepEmptyLinesAtTheStartOfBlocks
The anonymous variant of qmlRegisterType() is deprecated in Qt5 and
gone in Qt6.
This however now requires us to specify a module URI and major version
number. I used the names and (lowest) versions used already for other
types nearby where available, and fell back to "org.kde.kwin" and 0
otherwise.
In 52bc46069e, some code was shuffled
around to improve code readability. However, it was overlooked that
spa_meta_bitmap->offset is initialized too late, after QImage dest is
constructed. That's the reason why the left edge of the cursor is
wrapped around horizontally.
This change fixes the cursor glitch by ensuring that
spa_meta_bitmap->offset is initialized to proper value before getting
pointer to bitmap data. While on this, this change also moves
spa_meta_bitmap initialization code around to make spa_meta_bitmap setup
look less like a bowl of spaghetti, i.e. spa_meta_bitmap is initialized
first, and QImage dest is created with spa_meta_bitmap's values.
when an aurorae theme does not contain "mask" element we can safely assume that blur is not supported. In such case all blur calculations must not run at all. This will make all solid aurorae themes much lighter by default.
when aurorae decorated windows become maximized and back to normal, after a while they all start to disable blur for their decorated maximized windows.
- bug was tracked down to aurorae fault sending empty QRegions for its maximized windows. What probably happens is that because mask FrameSvgItem enabled borders change from AllBorders to NoBorder, mask FrameSvgItem calculations can not catch up
- the new approach is lighter than the previous one and simpler as margins and enabledborders for mask framesvgitem are not changed and in the c++ side no QRegions calculations are needed at all for maximized windows
- in my system with the new code changing from normal window to maximized one feels a bit snapper
Qt6 insists on that. We can do this either by including the moc files,
or by including the corresponding headers in the header defining the
properties, the former seems cleaner when possible.
This is an approach for aurorae engine to publish masks for its decorated windows in order to avoid out of window blurring at the decoration corners. Aurorae themes are now able to specify a **mask** element inside **decoration.svg** file like plasma themes already do. Mask is used afterwards to calculate theme's blur region.

This allows us to make the GLRenderTarget a bit nicer when using it to
wrap the default fbo as we don't know what the color attachment texture
is besides its size.
This means that the responsibility of ensuring that the color attachment
outlives the fbo is now up to the caller. However, most of kwin code
has been written that way, so it's not an issue.
Because the GLRenderTarget and the GLVertexBuffer use the global
coordinate system, they are not ergonomic in render layers.
Assigning the device pixel ratio to GLRenderTarget and GLVertexBuffer is
an interesting api design choice too. Scaling is a window system
abstraction, which is absent in OpenGL or Vulkan. For example, it's not
possible to create an OpenGL texture with a scale factor of 2. It only
works with device pixels.
This change makes the GLRenderTarget and the GLVertexBuffer more
ergonomic for usages other than rendering the workspace by removing all
the global coordinate system and scaling stuff. That's the
responsibility of the users of those two classes.
QPlatformScreen::virtualSiblings() must return a list of screens on the
virtual desktop, otherwise QToolTip will use
QGuiApplication::primaryScreen() instead of looking up the screen where
the decoration tooltip must be shown using QDesktopWidget::screenNumber().

recordFrame requires an openGL context. This is typically done after a
frame is rendered, but when we send a frame after a cursor move this is
not guaranteed.
