It's reasnoble to expect people to download an applet just before trying to change an existing applet using the alternatives system. Therefore doing the check at applet initialisation time is semantically wrong. Especially as it doesn't just disable the action but also skips creating it. Finally this gives a startup performance boost; loading all the applets metadata takes a small amount of time (~20 milliseconds) not really noticable when you're doing it once, but it adds up if you're doing it over multiple applets sequentially.
Plasma Framework
Foundational libraries, components, and tools of the Plasma workspaces
Introduction
The plasma framework provides the following:
- QML components
- A C++ library: libplasma
- Script engines
QML components
org.kde.plasma.core
Bindings for libplasma functionality, such as DataEngine and FrameSvg, see @ref core.
org.kde.plasma.components
Graphical components for common items such as buttons, lineedits, tabbars and so on. Compatible subset of the MeeGo components used on the N9, see @ref plasmacomponents.
org.kde.plasma.extras
Extra graphical components that extend org.kde.plasma.components but are not in the standard api, see @ref plasmaextracomponents.
org.kde.plasma.plasmoid
Attached properties for manipulating the current applet or containment, see @ref libplasmaquick
libplasma
This C++ library provides:
- rendering of SVG themes
- loading of files from a certain filesystem structure: packages
- data access through data engines
- loading of the plugin structure of the workspace: containments and applets
See @ref libplasma.
Script engines
Provides support to create applets or containments in various scripting languages.
