After splitting out the server part of KWayland into a separate repo,
all non-core protocol wrappers in KWayland::Client had become obsolete
and using them in new projects is highly discouraged.
The layer-shell protocol allows wayland clients to create surfaces that
can be used for building desktop environment components such as panels,
notifications, etc.
The support for the plasma-shell protocol will be dropped once plasma in
all its entirety is ported to the layer-shell protocol.
in XdgSurfaceClient setFrameGeometry is async,
so we can't rely on it having the final value immediately.
make setVirtualKeyboardGeometry a virtual.
in the implementation on setVirtualKeyboardGeometry
use requestedFrameGeometry() instead of frameGeometry()
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:
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.

Summary:
This change removes all traces of wl-shell in the test suite. That's a
prerequisite for dropping wl-shell support in KWin.
Given that wl-shell and xdg-shell are not interchangeable, some tests
were removed and initialization sequence in some tests was adjusted.
The most notable change is ensuring that each plasmashell window sets
its role and initial position before committing the surface. Setting
those properties before the first surface commit is important because
our window placement code needs to know window type in order to
avoid maximizing panels, popups, etc.

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:
Everything on the wl_surface is double buffered.
When we create an XdgShell toplevel or popup we shouldn't treat it as
attached until it's committed to the surface.
A client should commit the surface after it's sent it's initial state of
the Xdg topLevel; minimumSize, title, app_id, etc.
By blocking sending configure events we will have flushed the correct
initial state before sending a single atomic correct event to the
client. It also adds a hook to re-evaluate rules now that all properties
are set.
Arguably this applies to WlShellSurface too, but I've left it unchanged
as it's deprecated and hard to verify real client behaviour.

Summary:
In a recent patch the newly added xwayland class ended up being
responsible for continuing the startup, calling back into the main app
to spawn the workspace.
It moves the flow of startup about so it's not very readable or
following class structure.
This patch moves the code back into main_wayland and removes the
duplication between xwayland and non-xwayland modes.
There was also a misnaming of methods.
Previously:
continueStartupWithScreens was called after platform screens are created
continueStartupWithScene was called after the scene was created
continueStartupWithXwayland was called before xwayland is created
This was confusing, so the names have been shuffled around to follow a
consistent pattern of what has been done so far.

The connect to Compositor::sceneCreated must be disconnected again,
otherwise a restart of the Compositor results in Workspace being created
again.
Thanks to our autotests for finding this problem!
The integrationTest function takes a new optional argument whether the
test supports a Wayland Only mode. If that's the case the test is
compiled twice, once (as always) as "foo" with XWayland support and
once as "foo_waylandonly" without XWayland support.
This way we can ensure that our code always supports both modes. The
tests found multiple issues. At the moment fast running tests are
sporadically crashing on tear down. This needs further investigation.
Summary:
Adds XDGV6 support for the kwin side.
Popup placement support is limited to the stuff v5 had,
a simple offset, rather than the awesome new positioner.
But Qt doesn't make use of it yet either.
Also ideally we should do all the positioning before sending the first
configure, but again Qt doesn't actually do anything with that anyway.
Also integrate pinging clients

Summary:
There are two types of constraints supported:
1. Pointer confinement
2. Pointer locking
In the case of confinement the pointer is confined to a given region of
the surface. This is comparable to general operation where the pointer
is confined to the screen region.
In the second case the pointer gets locked. That means it cannot move at
all. No further position updates are provided, only relative motion
events can go to the application. There is a hint about cursor position
update on unlock which is not yet implemented in KWayland::Server, thus
also not in this change.
The implementation in KWin grants the requests for pointer constraints
when the pointer enters the constrained region, either by pointer
movement or by e.g. stacking order changes. There is no confirmation
from user required to enter that mode. But we want to show an OSD when
the pointer gets constrained, this is not yet implemented, though.
Breaking an active constraint is relatively easy. E.g. changing the
stacking order will break the constraint if another surface is under the
cursor. Also (in case of confinement) moving the pointer to an
overlapping window breaks the confinement. But as soon as one moves the
pointer back to the window a constraint might get honoured again.
To properly break there is a dedicated event filter. It listens for a
long press of the Escape key. If hold for 3sec the pointer constraint is
broken and not activated again till the pointer got moved out of the
window. Afterward when moving in the pointer might activate again.
The escape filter ensures that the key press is forwarded to the
application if it's a short press or if another key gets pressed during
the three seconds. If the three seconds way fires, the later escape
release is not sent to the application.
This basic interaction is also ensured through an added auto test.
This change implements T4605.

Summary:
So far when KWin intercepted a key event a leave was not sent to the
Wayland surface currently having keyboard focus. This could result in
the Wayland application to start repeating keys. E.g.
1. application gets key press event
2. This triggers an internal window to show
3. key release goes to KWin internal window
4. application starts to repeat key as there is no release
With this change whenever KWin intercepts the key event e.g. due to
* internal window
* Effects grabbing key event
* Tabbox
the focused keyboard surface is set to null, thus triggering a leave
event and the client not starting to repeat the event.

ShellClient gains some new ctors for the different variants and is

With this change KWin mostly supports xdg-shell protocol. Still missing
is support for the "geometry" request which is rather difficult to
implement in KWin.

the base set to be able to create a Surface and flags to create
additional interfaces. This replaces the KWayland connection dance in
init() methods. For cleanup() there is also a dedicated helper function.
In addition there are helper functions to:
* render a surface
* create a surface
* create a shell surface
* flush the wayland client connection
* access to the created interfaces - for compatibility with existing code
The idea is to extend this Test library also for other common use cases
like creating an X11 connection and X11 windows, etc.
