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). REVIEW: 107494

Split out screen handling from Workspace into own class Screens Following the approaches of other split out functionality Screens is a singleton class created by Workspace. The class takes over the responsibility for: * screenChanged signal delayed by timer * number of screens * geometry of given screen * active screen * config option for active screen follows mouse The class contains a small abstraction layer and has a concrete subclass wrapping around QDesktopWidget, but the idea is to go more low level and interact with XRandR directly to get more detailed information. All over KWin the usage from QDesktopWidget is ported over to the new Screens class. REVIEW: 109839

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. REVIEW: 109865

Use nullptr everywhere 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.

Use explicit Chain type in the focus chain Summary: The explicit Chain type makes code more cleaner. Test Plan: Still compiles. Reviewers: #kwin, davidedmundson Reviewed By: #kwin, davidedmundson Subscribers: kwin Tags: #kwin Differential Revision: https://phabricator.kde.org/D14431

Use nullptr everywhere 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.

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). REVIEW: 107494

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*.
