Detailed Description
The base class for plugins that provide backgrounds and applet grouping containers.
Containment objects provide the means to group applets into functional sets. They also provide the following:
creation of focusing event
- drawing of the background image (which can be interactive)
- form factors (e.g. panel, desktop, full screen, etc)
- applet layout management
Since containment is actually just a Plasma::Applet, all the techniques used for writing the visual presentation of Applets is applicable to Containtments. Containments are differentiated from Applets by being marked with the ServiceType of Plasma/Containment. Plugins registered with both the Applet and the Containment ServiceTypes can be loaded for us in either situation.
See techbase.kde.org for a tutorial on writing Containments using this class.

Member Enumeration Documentation
◆ Type
This enumeration describes the type of the Containment.
DesktopContainments represent main containments that will own a screen in a mutually exclusive fashion, while PanelContainments are accessories which can be present multiple per screen.
This value is specified in the "X-Plasma-ContainmentType" JSON-metadata value of containments.
