`MenuItem` does not delete other people's `QAction` but it does not take kindly to the `QAction` being deleted under it. As a workaround recreate a dummy action when ours gets destroyed. This crash can easily be triggered by opening the Media Controller applet and quickly right-clicking its icon to open the context menu. Media Controller recreates its actions in `contextualActionsAboutToShow`, which removes and deletes them. Then the `Instantiator` in System Tray's `ExpandedRepresentation` updates its `model`, deleting the delegate items (`MenuItem` instances) it created. This prompts the `Menu` to run `removeMenuItem` on the now removed `MenuItem`, accessing its backing `action()` to remove it from the menu, resulting in a crash as it was deleted earlier.
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.
