libinput_device_get_user_data() can be used to get the associated Device
object with libinput_device. That way, we won't need to maintain a
private list of all input devices.
The .clang-format file is based on the one in ECM except the following
style options:
- AlwaysBreakBeforeMultilineStrings
- BinPackArguments
- BinPackParameters
- ColumnLimit
- BreakBeforeBraces
- KeepEmptyLinesAtTheStartOfBlocks
The main motivation behind this change is to prepare input abstractions
for virtual input devices so the wl_seat can properly advertise caps or
the cursor getting properly mapped/unmapped when a fake pointer is
added/removed on a system without a hardware mouse connected.
With this, there are three abstractions - InputDevice, InputBackend, and
InputRedirection.
An InputDevice represents an input device such as a mouse, a keyboard, a
tablet, etc. The InputBackend class notifies the InputRedirection about
(dis-)connected devices. The InputRedirection manages the input devices.
Such design allows to unify the event flow for real and virtual input
devices.
There can be several input backends active. For example, the libinput
backend and an input backend that provides virtual input devices, e.g.
libeis or org_kde_kwin_fake_input.
Once in a while, we receive complaints from other fellow KDE developers
about the file organization of kwin. This change addresses some of those
complaints by moving all of source code in a separate directory, src/,
thus making the project structure more traditional. Things such as tests
are kept in their own toplevel directories.
This change may wreak havoc on merge requests that add new files to kwin,
but if a patch modifies an already existing file, git should be smart
enough to figure out that the file has been relocated.
We may potentially split the src/ directory further to make navigating
the source code easier, but hopefully this is good enough already.
Occasionally, I see complaints about the file organization of kwin,
which is fair enough.
This change makes the source code more relocatable by removing relative
paths from includes.
CMAKE_CURRENT_SOURCE_DIR was added to the interface include directories
of kwin library. This means that as long as you link against kwin target,
the real location of the source code of the library doesn't matter.
With autotests, things are not as convenient as with kwin target. Some
tests use cpp files from kwin core. If we move all source code in a src/
directory, they will need to be adjusted, but mostly only in build
scripts.
Warning messages are not the kind of messages that should be ignored,
they indicate that something is off or wrong.
Also, this makes triaging bugs easier as we no longer have to ask people
to run kwin with the QT_LOGGING_RULES environment variable set.
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.

We have lots of inconsistency at the moment in CMakeLists.txt files. Most
of it is due to kwin being a very old project. This change hopefully fixes
all of it.
Summary:
So far KWin didn't send axis_source, axis_discrete, and axis_stop. Even
though most of those events are optional, clients need them to work as
expected. For example, one needs axis_source and axis_stop to implement
kinetic scrolling; Xwayland needs axis_discrete to prevent multiple
scroll events when the compositor sends axis deltas greater than 10, etc.
BUG: 404152

Test Plan:
* Content of a webpage in Firefox is moved by one line per each mouse
wheel "click";
* Scrolled gedit using 2 fingers on GNOME Shell, sway, and KDE Plasma;
in all three cases wayland debug looked the same (except diagonal scroll
motions).

Summary:
When launching the touchpad kcm we see the following warning:
Error on d-bus read of "supportedButtons"
And the Gui shows "Error while loading values. See logs for more
information. Please restart this configuration module".
By extending the unit test for reading back the properties through DBus
I noticed that it's not trivially possible to export QFlags to DBus. As
the QFlags can be implicitly casted to int, the property is changed to
an int value.
Test Plan: Test case adjusted, did not pass prior to change, passes now.

Summary:
This change adds support for the switch devices introduces with libinput
1.7 (lid) and 1.9 (tablet mode). So far it's not yet used internally in
KWin, but only exposed through the Device and Events.
As KWin currently only requires libinput 1.5 and we are rather late in
the release cycle the new functionality is ifdef'ed. The requirement
will be raised once master is 5.13. It is already available on
build.kde.org, but e.g. Neon only has 1.6.
The switch events are interesting as they report whether the lid is
closed (might be interesting for e.g. powerdevil) and whether a
convertible is in tablet mode (supported for e.g. Lenovo Yogas with
recent kernel). This can be used by KWin internally to enable/disable
the virtual keyboard. And can be exposed globally to switch to Plasma
Mobile shell in future.
Test Plan:
Only through test case as my Lenovo Yoga uses Neon which has a
too old libinput

Summary:
This change finds the screen for a touch screen device based on:
* number available screens
* output name defined on the touch screen device
* internal screen
* and physical size
The id of the screen is stored in the Device allowing to adjust the
touch points accordingly. This means instead of transferring to the
combined display size the touch points are transferred into the output
space and the position of the output is added. Thus in a multi screen
system the touch points are properly mapped to the output.
Furthermore the screen orientation is passed to the Device and a
calibration matrix is set accordingly. Thus a transformed screen has the
touch screen transformed accordingly.
Please note that this only affects libinput on Wayland and not on X11!
The x11 standalone platform needs to gain similar code.

Summary:
KWin was quite good in ensuring that you don't need to install by
passing paths to the tests. The new way is much nicer, so code is
adjusted for the new way. Also if we require a newer ECM in future we
need to support the new way.
No guarantee that the tests don't pick something up from the system env,
that needs more testing.

Summary:
Libinput returns -1 when calling libinput_event_touch_get_slot on an event
from a single-touch touchscreen. The returned value is used in
DecorationEventFilter to determine the touch which is acting on it. The value -1
is used to signify that the decoration is not being acted on. Thus when
releasing the touch, it checks whether it was being dragged, and as it thinks
it isn't, it doesn't handle it and the decoration is still being dragged.
Clicking on the decoration then crashes kwin.
Test Plan: Move a window by dragging the decoration with a single-touch touchscreen.

Go for a more intuitive unset behaviour of scroll method and acceleration
profile properties.
Summary:
Unsetting a scroll method should only work, if the scroll method is currently
active. For example when scroll-two-finger is active (i.e. scroll-edge,
scroll-on-button-down is not active):
* unsetting scroll-two-finger should deactivate it and activate no-scroll
* but unsetting for example scroll-edge should _not_ deactivate scroll-two-
finger and _not_ activate no-scroll
Reworked setting scroll method auto test in order to test it.
Regarding acceleration profiles: Unsetting one, should always switch to the
other possible one as long as both are supported. In this case
LIBINPUT_CONFIG_ACCEL_PROFILE_NONE is not a valid option in contrast to the
definition of the scroll method enums.

This is a larger patch rewriting some parts of the config saving functionality
in device.cpp in order to:
1. Make it possible to save ScrollMode as integer instead of using three booleans
2. Simplify the addition of new keys or types in the future
Changes in detail:
a) Adds new ConfigKey ScrollMethod and removed now unnecessary keys per method
b) Adds constructors to the ConfigData struct. This allows to create ConfigData
entries for s_configData without the need of stating empty brackets and the
useage of default values.
c) Use plain member function pointers instead of std::function, in order to
compactify code and have better compile output in case something goes wrong.
c) Cleans up ScrollMethod functions and adds interface methods for transforming
the saved integer into type enum libinput_config_scroll_method.
d) Adjusts auto test for loading the ScrollMethod value from the config file.

Some small improvements / fixes to the libinput backend:
- Query libinput_device_config_left_handed_get_default
- Write leftHanded property to config file
- When saving the touchpad scroll mode, write false to all other ones.
Otherwise it will always enable the last read entry after reboot.
- Use macro for setLeftHanded(bool) and setNaturalScroll(bool)

Summary:
Device gets a KConfigGroup injected and supports loading device-specific
settings. This is invoked from Libinput::Connection when adding a new
Device.
Whenever a Device option is changed successfully through the DBus
interface it gets synced into the KConfigGroup, thus on next loading of
the Device it gets restored.
The config group follows a pattern of:
[libinput][vendor][product][name]
Thus every device has a specific and persistent configuration.
Test Plan: So far only tested through autotests
