/**
|

|
* @short 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:
|
||||||
|
*
|
||||||
|
* - 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.
