How does Plasma work?
Plasma’s components are widgets called Plasmoids. Plasmoids can take on a variety of functions, ranging from displaying your desktop and associated wallpaper, showing your laptop’s battery level, displaying your plugged in devices, and drawing the taskbar: basically, they are small applications that live on the desktop. Plasmoids can be grouped together in “containers” called containments. On a default desktop, there are two main elements: the Panel and the desktop itself. Both are containments in the Plasma sense.
