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.
Summary:
Uses the tablet classes introduced in kwayland.
Depends on D26858
Test Plan:
Scratched my tablet with a magic stick and it did things depending on the pressure.

Summary:
So far we were following a bit unique and rare doxygen comment style:
/**
* Contents of the comment.
**/
Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer
more traditional doxygen comment style, i.e.
/**
* Contents of the comment.
*/
Reviewing such changes has been a bit frustrating for me (so selfish!)
and for other contributors.
This change switches doxygen comment style in KWin to a more traditional
style. The main reason for doing this is to make code review process easier
for new contributors as well us.

Summary:
Currently code base of kwin can be viewed as two pieces. One is very
ancient, and the other one is more modern, which uses new C++ features.
The main problem with the ancient code is that it was written before
C++11 era. So, no override or final keywords, lambdas, etc.
Quite recently, KDE compiler settings were changed to show a warning if
a virtual method has missing override keyword. As you might have already
guessed, this fired back at us because of that ancient code. We had
about 500 new compiler warnings.
A "solution" was proposed to that problem - disable -Wno-suggest-override
and the other similar warning for clang. It's hard to call a solution
because those warnings are disabled not only for the old code, but also
for new. This is not what we want!
The main argument for not actually fixing the problem was that git
history will be screwed as well because of human factor. While good git
history is a very important thing, we should not go crazy about it and
block every change that somehow alters git history. git blame allows to
specify starting revision for a reason.
The other argument (human factor) can be easily solved by using tools
such as clang-tidy. clang-tidy is a clang-based linter for C++. It can
be used for various things, e.g. fixing coding style(e.g. add missing
braces to if statements, readability-braces-around-statements check),
or in our case add missing override keywords.
Test Plan: Compiles.

Summary:
At the moment it's broken for many of the laptops I've seen, this opens the possibility to start toying with them. The right fix would be to get the kernel to emit the right signals but I'm afraid for some hardware it will be close to impossible.
This includes a kconfig variable variable that will detect it as follows: if there's a touchscreen, when the touchpad gets removed we are on tablet mode (i.e. the pointing will be done using the finger), when it's connected back tablet mode will be restored.

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.

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

Summary:
The Connection exposes a new service called org.kde.KWin.InputDevice
and every Device registers an own object exposing all properties.
This allows an external configuration tool to change the behavior of
the devices at runtime. E.g. to test configuration settings.

From libinput documentation:
Also optional is a feature called "drag lock". With drag lock disabled,
lifting the finger will stop any drag process. When enabled, libinput
will ignore a finger up event during a drag process, provided the finger
is set down again within a implementation-specific timeout.
From libinput documentation:
A tap immediately followed by a finger down and that finger being held
down emulates a button press. Moving the finger around can thus drag
the selected item on the screen.
Summary:
Device has a static QVector<Device*> into which each created Device
is added and provides a static method to match a libinput_device* to
the already created Device.
This can be used by the the libinput Event class wrapper to properly
reference the Device the event is for.

Summary:
The LibInput::Device provides a way to enable/disable the device.
This is used by the Connection to toggle all touchpad devices on/off
when the touchpad key is pressed. For this KWin "steals" the global
shortcuts from the touchpad kded.
Detecting what is a touchpad is unfortunately not tivial. The code
uses the following approach:
* it's a pointer
* it's not also a keyboard or touch screen
* it's at least one of the following:
** supports multiple tap fingers
** supports disable while typing
** supports disable on external mouse
If the code finds a touchpad and changes it's state successfully,
it triggers the touchpadEnabledChanged on Plasma's osdService.
Test Plan: Tested on notebook with toggle touchpad button

Summary:
The configuration file kcminput, group Mouse is parsed to decide whether
pointer devices should be in left handed mode. The config is applied
whenever a new device is added.
In addition the Connection listens to KGlobalSettings for a mouse
settings changed signal which might be emitted by the mouse KCM.
When such a signal is emitted, all pointer devices are reconfigured.
This allows to change the mouse handed settings on Wayland.

Summary:
The Device class wraps all the information we can get from libinput
about the device, like whether it's a keyboard, pointer, touch, etc.
In addition some more information is queried to figure out how "useful"
a device is. For a keyboard all alphanumeric keys are checked whether
they exist, for a pointer all (normal) buttons are queried.
All the information is exposed as Q_PROPERTY and used by the
DebugConsole. The DebugConsole gained a new tab "Input Devices" which
renders all devices and their properties in a tree view. When plugging
in/out a device, the model gets reset, so it's always up to date.
The new Device class can be used in future to configure the device,
e.g. disable touch pad, set mouse acceleration, etc.
