< Development | Architecture/KDE4Revision as of 09:20, 14 July 2012 by AnneW (talk | contribs)(diff) ← Older revision | Latest revision (diff) | Newer revision → (diff) Plasma is the name of the new desktop planned to replace KDesktop in KDE4. You may think that it is a union of SuperKaramba and KDesktop, but it's more. It's a whole concept of functionality and beauty. Its implementation is based on the Qt Graphics View Framework introduced in Qt 4.2. From a developer point of view there are some classes in libplasma who play central roles. Corona: extends QGraphicsScene and provides functionality for adding applets and karamba themes. Widget: extends QGraphicsItem and works as simple elements in the desktop. There are some built-in in libplasma as icons or buttons. Applet: extends Widget and implements sophisticated functionality as rss display, a clock or system monitoring. DataEngine: The common use of a DataEngine is to provide data to an applet for display. This allows a user interface elements to show all sorts of data.
