This article is about the window manager.

KWIN.
KWin is a window manager for the X Window System and is currently in the process of becoming a Wayland compositor.[3] It is released as part of KDE Plasma 5 for which it is the default window manager. KWin can also be used on its own or with other desktop environments.
KWin 5.x depends on KDE Frameworks 5. KWin 4.x depended on KDE Platform 4, which was a monolithic library. KWin 3.x and earlier depended on KDELibs.
KWin can be configured by scripting using QML or QtScript, both of which are based on ECMAScript.[4]
