Vlad Zahorodnii 4ce853e8e4 Prettify license headers 2020-08-07 19:57:56 +00:00
Vlad Zahorodnii 1fb9f6f13a Switch to SPDX license markers
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.

Nate Graham cc862fa674 [focuschain/task switcher] Remove special handling for minimized windows
Right now KWin moves minimized windows to the end of the task switcher's
ordering. However this is a rather confusing and undocumented behavior
that explicitly overrides the user's chosen sort ordering, be it
"Recently used" or "Stacking order". This makes it a hidden magic behavior
of the type that is at risk of being more annoying than useful.

This commit removes the special handling and lets minimized windows live
in the appropriate order in the task switcher.

Vlad Zahorodnii ffcbe24e2b Rename Client to X11Client
Summary:
Currently each managed X11 client is represented with an instance of
Client class, however the name of that class is very generic and the
only reason why it's called that way is because historically kwin
was created as an x11 window manager, so "Client" was a sensible choice.

With introduction of wayland support, things had changed and therefore
Client needs to be renamed to X11Client in order to better reflect what
that class stands for.

Renaming of Client to X11Client was agreed upon during the last KWin
sprint.

Test Plan: Compiles, the test suite is still green.

Vlad Zagorodniy 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.

Vlad Zagorodniy 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.

Martin Gräßlin d4f7445749 Remove remaining Client usage from FocusChain 2015-05-08 12:43:46 +02:00
Martin Gräßlin fe7a6834b2 FocusChain operates on AbstractClient instead of Client
As external interface it still returns Client* to not force the casts
to be done at usages. This will be changed once the users are migrated
to AbstractClient*.

Martin Gräßlin 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.

Martin Gräßlin 4a0a4bc27e Split out handling of focus chain into an own class
The new class FocusChain manages two different kind of focus chains.
First of all there is a most recently used focus chain which is primarily
used for TabBox.

Then there is one focus chain per virtual desktop. These chains are used
to determine which Client needs to be activated when e.g. switching to a
virtual desktop.

The individual chains are implemented as a simple QList of Client* with
the most recently used Client as the last element. That way one can see
it as a LIFO like structure.

The desktop focus chains are internally represented as a hash with the id
of the virtual desktop as the key and a list as described as the value.

FocusChain is a singleton which provides some methods to manipulate the
chains and to get a specific Client for a task (e.g. TabBox).

While splitting out the code some unused code inside TabBox got removed
as well as some activities related code (windows cannot be moved while
switching activities).
