Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.
This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).
Test Plan: Compiles.

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:
Switch to Q_ASSERT in order to make code a bit more consistent. We have
places where both assert and Q_ASSERT are used next to each other. Also,
distributions like Ubuntu don't strip away assert(), let's hope that
things are a bit different with Q_ASSERT.
Test Plan: Compiles.

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:
So far the ThumbnailItem in TabBox mode used the window id for finding
the window it should render a thumbnail on. In the Wayland world this is
not unique. The window id could be either an X11 window or a wayland
window. We don't guarantee that there are no conflicting ids.
With the internal id we have a way to properly identify the windows, so
this element should use them.
To support this the property changed the type to QUuid and the
clientmodel also provides the QUuid. As in TabBox the way to get the
window is through the model this should be compatible for all themes.
It's tested and verified with the Breeze switcher.
For declarative KWin scripts the ThumbnailItem also provides the
AbstractClient as a property, so there should not be any script which
uses wid. If it does, this could break, but well the script should use
the intended API.
Test Plan: ctest passes, manual testing of Breeze alt-tab switcher

Summary:
KWin used to do a quirky trick to send key events to the topmost QQuickItem
rather than things going to the activeFocus item.
Sending it to the window previously would have failed as the window
didn't think it was active.
Since 66986d4afd we can just let the
window process the events in a normal QtQuick manner.

When I'm explicitly cycling through the windows of an application it makes no sense to show the "global" desktop window.
BUG: 378662
FIXED-IN: 5.12.0
Differential Revision: https://phabricator.kde.org/D9661
Summary:
Commit 5d9027b110 introduced a regression in TabBox by using the generic
framework inside KWin to test for same application. What I did not
consider was that the code in TabBox was "broken by design". It didn't
use the generic check as that is too strict and considers windows from
different processes as not belonging to the same application. But this
is not wanted in the case of TabBox.
On the other hand the change itself is an improvement to also support
Wayland in a better way and not have special handling situations. Thus
just reverting would not help.
Instead this change addresses the problem by extending the internal API
and to allow more adjustements. So far there was already an
"active_hack" boolean flag. This is extended to proper flags with an
additional flag to allow cross application checks.
The checks in Client which would filter out different applications check
for this flag and are skipped if set. In addition ShellClient also adds
support for this flag and compares for the desktop file name.
Thus we get in TabBox the same behavior as before with the advantage of
having a better shared code base working on both X11 and Wayland.

Summary:
If an Effect has replaced the TabBox and wants to react on mouse events
the EffectsHandlerImpl also has an X11Filter, so we only need to make
sure the events go to that filter.
Motion: TabBox did not filter out, so events will go to the Effects
filter.
Press/Release: TabBox should not operate if Effects take the events.
The events are filtered out by Effects if there is a grab, so just
check for that and go out. Effects will take care.

Summary:
Creating the X11Filter directly on startup caused a regression as the
filter got too early in the chain and stole events from the
XInputIntegrationFilter. We don't need the filter all the time, but only
when we have established the TabBox grab. Likewise we can destroy the
filter again when releasing the TabBox grab. So it's much more
encapsulated now.

better, in a standardized way and even across windowing system.

Summary:
There is a special mode in TabBox which is the noModifierGrab mode. This
is Alt+Tab active without a modifier being hold. This mode is entered
when being activated through screen edges (either pointer or touch). So
far this was not exposed to QtQuick and thus one could not end the mode
using pointer or touch. It is possible to select another window, but not
to activate it. That required the press of a keyboard key.
This setup is rather unfortunate. By exposing the mode to QtQuick we can
react from QtQuick side to it and invoke already exposed functionality to
select and item and directly activate it - existing left-over from the
Plasma Active window switcher.
Test Plan:
Tested on X11 and Wayland with an adjusted lnf package. It kind
of works, but there are additional issues on both X11 and Wayland.

Summary:
Prior to this change various event filters performed deep calls into
Xkb class to figure out the modifiers relevant for global shortcuts (aka
consumed modifiers). This shows that this is a general useful
information which should be available to all input event filters
directly.
Thus it's now added to the input events and exposed directly in
InputRedirection so that the calls into Xkb are no longer needed.

Summary:
The TabBox performs the scrolling of the items by itself in order to
support wheel events even if the mouse is not on the TabBox. For that
KWin grabs pointer events on X11 (on Wayland an input filter is used)
and forwards them to the TabBox.
Qt uses Xinput2 for scrolling on the QQuickWindow. Due to that KWin
does not get any xcb core button press/release events when scrolling
inside the QQuickWindow and thus scrolling doesn't work.
There are three possible approaches to fix this:
1. Implement scrolling support in each of the QML switchers
2. Add an xinput2 filter to TabBox
3. Intercept the QWheelEvents on the QQuickWindow
The first approach has the disadvantage that all themes need
adjustment and that there might be behaviorial difference whether one
scrolls on the TabBox window or outside the window.
The second approach would be most in line with the other filters, but
is difficult due to the nature of xinput2 (no xcb bindings, etc).
Thus the third approach might be the best solution. Wheel events are
only delivered to the QQuickWindow if the native events were not already
intercepted, thus we know it won't have side effects for the case that
Wayland is used or xinput2 is not supported.
The implementation installs an event filter on the QQuickWindow which
gets created when showing the TabBox and inside the filter waits till
there is an angleDelta of +/-120 and scrolls by one per every 120 angle
delta as described in the QWheelEvent documentation.

Summary:
The interaction is changed to trigger the check for release from the
TabBoxInputFilter instead of reacting on modifier changes. That way
it's possible to check for the relevant modifiers getting released
instead of getting all modifiers in. Also this means that the checks
are only performed when relevant.
