  * @class KAbstractFileItemActionPlugin kabstractfileitemactionplugin.h <KAbstractFileItemActionPlugin>
  *
  * @brief Base class for KFileItemAction plugins.
  *
  * KFileItemAction plugins allow dynamic features to be added to the context
  * menus for files and directories when browsing.
  *
  * Most filetype-based popup menu items can be implemented using servicemenus
  * linked to MIME types, and that should be the preferred way of doing this.
  * However, complex scenarios such as showing submenus with a variable number of
  * actions or only showing an item if exactly two files are selected need to be
  * implemented as a KFileItemAction plugin.
  *
  * To create such a plugin, subclass KAbstractFileItemActionPlugin and implement
  * actions() to return the actions to want to add to the context menu.  Then
  * create a plugin in the usual KPluginFactory based way:
  * \code
  * K_PLUGIN_CLASS_WITH_JSON(MyActionPlugin, "myactionplugin.json")
  * #include <thisfile.moc>
  * \endcode
  *
  * A desktop file is necessary to register the plugin with the KDE plugin system:
  *
  * \code
  * [Desktop Entry]
  * Type=Service
  * Name=My fancy action plugin
  * X-KDE-Library=myactionplugin
  * X-KDE-ServiceTypes=KFileItemAction/Plugin
  * MimeType=some/mimetype;
  * \endcode
  *
  * Note the \p KFileItemAction/Plugin service type which is used by
  * KFileItemActions::addServicePluginActionsTo() to load all available plugins
  * and the \p MimeType field which specifies for which types of file items
  * the setup() method should be called.
  *
  * The desktop file contents must also be compiled into the plugin as JSON data.
  * The following CMake code builds and installs the plugin:
  * \code
  * kcoreaddons_add_plugin(myactionplugin SOURCES myactionplugin.cpp INSTALL_NAMESPACE "kf5/kfileitemaction")
  * kcoreaddons_desktop_to_json(myactionplugin myactionplugin.desktop) # generate the json file
  *
  * target_link_libraries(myactionplugin KF5::KIOWidgets)
  * \endcode
  *
  * @note the plugin should be installed in the "kf5/kfileitemaction" subfolder of $QT_PLUGIN_PATH.
  * @note If the plugin has a lower priority and should show up in the "Actions" submenu,
  * you can set the X-KDE-Show-In-Submenu property to true.
  *
