Detailed Description

KisPart a singleton class which provides the main entry point to the application. Krita supports multiple documents, multiple main windows, and multiple components. KisPart manages these resources and provides them to the rest of Krita. It manages lists of Actions and shortcuts as well.

The terminology comes from KParts, which is a system allowing one KDE app to be run from inside another, like pressing F4 inside dolphin to run konsole.

Needless to say, KisPart hasn't got much to do with KParts anymore.
