Detailed Description

Represent a service, like an application or plugin bound to one or several MIME types (or servicetypes) as written in its desktop entry file.

The starting point you need is often the static methods, like createInstance(). The types of service a plugin provides is taken from the accompanying desktop file where the 'X-KDE-ServiceTypes=' field is used.

For a tutorial on how to build a plugin-loading mechanism and how to write plugins in general, see http://techbase.kde.org/Development/Tutorials#Services:_Applications_and_Plugins

const

A desktop file name that this service is an alias for.

This is used when a NoDisplay service is used to enforce specific handling for an application. In that case the NoDisplay service is an AliasFor another service and be considered roughly equal to the AliasFor service (which should not be NoDisplay=true) For example okular supplies a desktop file for each supported format (e.g. PDF), all of which NoDisplay and merely there to selectively support specific file formats. A UI may choose to display the aliased entry org.kde.okular instead of the NoDisplay entries.

The keyword is defined with X-KDE-PluginKeyword in the .desktop file and with registerPlugin<T>(keyword) in the K_PLUGIN_FACTORY macro when implementing the plugin.

Deprecated:

Since 5.87, the metadata should be embedded in the actual plugin. Consequently this property is obsolete. In case there is only one plugin in the library the usage is not needed. In case there are different base classes registered the keyword is not needed too. If there are multiple classes of a common base class registered they should be split up in separate libs.
