e144748c7a Add some const &
Summary:
Won't make things go much faster since everything that was
being passed by value is refcounted but still const & is a bit faster
than refcounting

For shared pointers instead of adding const & we move them into the
destination variable saving some cpu usage but at the same time making
clear the pointer is being stored by not being const &

684b4b635e Use more traditional doxygen style
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.

8af2fa73dc Run clang-tidy with modernize-use-override check
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.

7b20e1f66f Overhaul doxygen comments
Summary:
We have a mix of different doxygen comment styles, e.g.

    /*!
      Foo bar.
     */

    /**
     * Foo bar.
     */

    /** Foo bar.
     */

    /**
     * Foo bar.
     */

    /**
     * Foo bar.
     **/

To make the code more consistent, this change updates the style of all
doxygen comments to the last one.

Test Plan: Compiles.

7274aed544 Fix VirtualDesktopManager::createVirtualDesktop
Summary:
Currently, there are several issues with
VirtualDesktopManager::createVirtualDesktop:

(a) The method expects the number parameter to be in range [1, count + 1],
    but we pass [0, count];
(b) It doesn't correctly update X11 desktop numbers.

This change tries to address all previously mentioned issues.

BUG: 403312
FIXED-IN: 5.15.0

Test Plan: No longer able to reproduce bug 403312.

Summary:
* save changes to the config files when the layout is saved
* :name() works even if netrootinfo isn't there
* as soon a rootinfo is set, connect all the desktops with name changes

Test Plan:
* tested with the kcm to add, remove and rename desktops, all of that works
* setting the number of rows still only partly works: kwin notices it but
the pager doesn't notice, a plasma restart is needed

7e8facc3fd [wayland] Use the new plasma virtual desktop protocol
Summary:
implement virtual desktop support for Wayland.
use the new virtual desktop protocol from D12820
The VirtualDesktopManager class needed some big change in order
to accomodate it, which is where most changes are.
Other than that, it's mostly connections to wire up
VirtualDesktopsManager and VirtualDesktopsManagement(the wayland protocol impl)

Depends on D12820
Other notable detail, is the client visibility updated to reflect the presence
of the client in the plasmavirtualdesktop.
(and the unSetDesktop concept)

Test Plan: used a bit a plasma session together with D12820, D13748 and D13746

f988a5f654 Reload VirtualDesktop settings after passing RootInfo on VirtualDesktopManager
Summary:
The load method and updateLayout ensure the virtual desktop information
is synced to RootInfo and thus to other X11 applications. Thus we need
to call it again when initing X11.

BUG: 385260

Test Plan: Not tested as I'm on Wayland, but given the changes it's obvious.

bf99d9ffdd Introduce support for keyboard layout switching policies
Summary:
This change introduces the initial support for keyboard layout switching
policies like in the X11 session. This first change only adds support for
Global and Virtual Desktop policy. This means the current layout is
stored in context to the current virtual desktop. Whenever one changes
the virtual desktop the previous layout is restored. If the user has not
yet navigated to this virtual desktop a switch to default layout is
performed.

This is the first code interacting with the new Virtual Desktop API which
is not based on integer ids. To fully support this the API is slightly
extended.

Test Plan: Added test case

22c91df2ec Add support for global touchpad swipe gestures
Summary:
This change adds global touchpad swipe gestures to the
GlobalShortcutsManager and hooks up the swipe gestures as defined at the
Plasma Affenfels sprint:
 * swipe up: Desktop Grid
 * swipe down: Present Windows
 * swipe left: previous virtual desktop
 * swipe right: next virtual desktop

The main work is handled by two new classes: SwipeGesture and
GestureRecognizer. This is implemented in a way that it can be extended
to also recognize touch screen gestures and pinch gestures.

The SwipeGesture defines what is required for the gesture to trigger.
Currently this includes the minimum and maximum number of fingers
participating in the gesture and the direction. The gesture gets
registered in the GestureRecognizer.

The events for the gesture are fed into the GestureRecognizer. It
evaluates which gestures could trigger and tracks them for every update
of the gesture. In the process of the gesture tracking the
GestureRecognizer emits signals on the Gesture:
 * started: when the Gesture gets considered for a sequence
 * cancelled: the Gesture no longer matches the sequence
 * triggered: the sequence ended and the Gesture still matches

The remaining changes are related to hook up the existing shortcut
framework with the new touchpad gestures. The GlobalShortcutManager
gained support for it, InputRedirection and EffectsHandler offer methods
to register a QAction. VirtualDesktopManager, PresentWindows and
DesktopGrid are adjusted to support the gesture.

c0b2e5dc8b VirtualDesktopGrid operates on VirtualDesktop objects
Summary:
The VirtualDesktopGrid is ported to the new VirtualDesktop objects. The
grid consists now of QVector<VirtualDesktop*> rows and a QVector of
those rows.

This change requires to adjust the code using the VirtualDesktopGrid.
This mostly affects VirtualDesktopManger. The methods for toLeft, above,
next, etc are now all operating on VirtualDesktop with the uint variants
- if still present - only delegating to the new method. The Functor
objects are also adjusted, though mostly still providing the old API for
compatibility.

In KWin core only one now ambiguous call is adjusted (useractions) and
the desktop grid usage in EffectsHandlerImpl is adjusted. Other usages
are not yet adjusted and need porting to fully get rid of the old
uint-based API.

Test Plan: VD test still passes

4f4d9d5cfe Introduce a VirtualDesktop class
Summary:
This is the first change for a larger virtual desktop refactoring. So
far for X11 virtual desktops are just a number. The current virtual
desktop is a number between 1 and the count of virtual desktops.

Similar a Toplevel is on the virtual desktop by setting the number as a
property.

In the long run we want to change that and allow to have windows on
multiple virtual desktops and also support virtual desktops on Wayland.
On Wayland a virtual desktop will be an object.

As a first step a VirtualDesktop class is introduced which currently is
just a glorifed wrapper around the x11 desktop number. The
VirtualDesktopManager now holds a pointer to the current desktop and the
available desktops are a QVector of VirtualDesktops. The implicit
mapping to counting of desktops is removed. Though the internal API is
still completely count based. In follow up changes this will be turned
into being more and more VirtualDesktop based. At least the Core should
be completely transferred to be VirtualDesktop based instead of uint
based.

Test Plan:
virtual desktop auto test still passes (test coverage 97 % line,
83 % conditionals)

0fb27fd12e Defines to create the boilerplate code for KWin's singleton classes
The define KWIN_SINGLETON adds to a class definition:

public:
    static Foo *create(QObject *parent = 0);
    static Foo *self() { return s_self; }
protected:
    explicit Foo(QObject *parent = 0);
private:
    static Foo *s_self;

There is an additional define KWIN_SINGLETON_VARIABLE to set a different
name than s_self.

The define KWIN_SINGLETON_FACTORY can be used to generate the create
method. It expands to:

Foo *Foo::s_self = 0;
Foo *Foo::create(QObject *parent)
{
    Q_ASSERT(!s_self);
    s_self = new Foo(parent);
    return s_self;
}

In addition there are defines to again set a different variable name and
to create an object of another inheriting class.

All the classes currently using this pattern are adjusted to use these
new defines. In a few places the name was adjusted. E.g. in Compositor
the factory method was called createCompositor instead of create.

334b4bf622 Move handling of Virtual Desktops into a VirtualDesktopManager
The ownership for virtual desktops is moved from Workspace into a new
VirtualDesktopManager. The manager is responsible for providing the count
of virtual desktops and keeping track of the currently used virtual
desktop.

All methods related to moving between desktops are also moved from
Workspace to the new manager, though all methods related to Clients on
Virtual Desktops remain in Workspace for the time being. This is to have
the new manager as independent from KWin core as possible.

An rather important change for the handling of virtual desktops is that
the count and the id of a desktop is now an unsinged integer instead of
an integer. The reason for that is that we cannot have a negative count
of desktops as well as it is not possible to be on a desktop with a
negative identifier.

In that regard it is important to remember that a Client can be on a
desktop with a negative identifier. The special value for a Client being
on all desktops is handled by using -1 as a desktop. For the time being
this is not adjusted but instead of comparing the virtual desktop ids one
should prefer to use the convenient methods like isOnDesktop and
isOnAllDesktops. This would allow in future to internally change the
representation for on all desktops.
