Use input device specific apis to change the position of the cursor. The
main reason to do so is to break the assumption that Cursor position is
the same as pointer position, which I would like to rely on later to
merge tablet and pointer cursors.
We use the PMF syntax so the isValid() check is unnecessary as the
compiler will notify about wrong signal at compile time. It makes
writing autotests feel less boilerplaty.
Things such as Output, InputDevice and so on are made to be
multi-purpose. In order to make this separation more clear, this change
moves that code in the core directory. Some things still link to the
abstraction level above (kwin), they can be tackled in future refactors.
Ideally code in core/ should depend either on other code in core/ or
system libs.
This change adjusts the window management abstractions in kwin for the
drm backend providing more than just "desktop" outputs.
Besides that, it has other potential benefits - for example, the
Workspace could start managing allocation of the placeholder output by
itself, thus leading to some simplifications in the drm backend. Another
is that it lets us move wayland code from the drm backend.
With fractional scaling integer based logical geometry may not match
device pixels. Once we have a floating point base we can fix that. This
also is
important for our X11 scale override, with a scale of 2 we could
get logical sizes with halves.
We already have all input being floating point, this doubles down on it
for all remaining geometry.
- Outputs remain integer to ensure that any screen on the right remains
aligned.
- Placement also remains integer based for now.
- Repainting is untouched as we always expand outwards
(QRectF::toAdjustedRect().
- Decoration is untouched for now
- Rules are integer in the config, but floating in the adjusting/API
This should also be fine.
At some point we'll add a method to snap to the device pixel
grid. Effectively `round(value * dpr) / dpr` though right now things
mostly work.
This also gets rid of a lot of hacks for QRect right and bottom which
are very
confusing.
Parts to watch out in the port are:
QRectF::contains now includes edges
QRectF::right and bottom are now sane so previous hacks have to be
removed
QRectF(QPoint, QPoint) behaves differently for the same reason
QRectF::center too
In test results some adjusted values which are the result of
QRect.center because using QRectF's center should behave the same to the
user.
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.
The .clang-format file is based on the one in ECM except the following
style options:
- AlwaysBreakBeforeMultilineStrings
- BinPackArguments
- BinPackParameters
- ColumnLimit
- BreakBeforeBraces
- KeepEmptyLinesAtTheStartOfBlocks
With a "Surface" type in kwin, KWayland::Client::Surface without fully
specified namespace will conflict with kwin's Surface type.
In some way, it also improves readability as it's clear where Surface
comes from.
Since the Screens class is a convenience wrapper around AbstractOutput
objects that come from the Platform, it should not be platform-specific.
By dropping createScreens(), output-related code becomes simpler.
The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.
In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.
The new signal is emitted when the Application has fully been initialized.
It allows us to change the startup sequence, for example create workspace
before starting the Xwayland server, without making any adjustments in our
test suit.
Summary:
As is KWin only had 1 Cursor which was a singleton. This made it impossible for
us to properly implement the tablet (as in drawing tablets) support and show where
we're drawing.
This patch makes it possible to have different Cursors in KWin, it makes all the
current code still follow the mouse but the tablet can still render a cursor.
Test Plan: Tests pass, been using it and works as well as before but with beautiful tablet cursors.

Summary:
xdg-shell stable has been around for quite a while. A quick analysis
showed that many distros ship GTK and Qt that support both xdg-shell
v6 and stable. Therefore, we can drop support for legacy v6 protocol.

Summary:
Currently, we have only one shell client type - XdgShellClient. We use
it when we are dealing with Wayland clients. But it isn't really a good
idea because we may need to support shell surfaces other than xdg-shell
ones, for example input panel surfaces.
In order to make kwin more extensible, this change replaces all usages
of the XdgShellClient class with the AbstractClient class.
Test Plan: Existing tests pass.

Summary:
Currently we have two signals that are emitted when the Toplevel's geometry
changes - geometryShapeChanged() and geometryChanged(). The former signal
is used primarily to invalidate cached window quads and the latter is
sort of emitted when the frame geometry changes. But it's not that easy. We
have a bunch of connects that link those signals together...
The worst part about all of this is that the window quads cache gets
invalidated every time a geometry update occurs, for example when user
moves a window around on the screen.
This change introduces a new signal and deprecates the existing geometryChanged
signal. frameGeometryChanged is similar to geometryChanged except that it is
emitted when an _actual_ geometry change has occurred.
We do still emit geometryShapeChanged signal. However, in long term, we
need to get rid of this signal or come up with something that makes sense
and doesn't require us to waste computational resources.

Summary:
In order to properly implement xdg_surface.set_window_geometry we need
two kinds of geometry - frame and buffer. The frame geometry specifies
visible bounds of the client on the screen, excluding client-side drop
shadows. The buffer geometry specifies rectangle on the screen that the
attached buffer or x11 pixmap occupies on the screen.
This change renames the geometry property to frameGeometry in order to
reflect the new meaning assigned to it as well to make it easier to
differentiate between frame geometry and buffer geometry in the future.
