Detailed Description

Information about a plugin.

This holds all the information about a plugin there is. It's used for the user to decide whether he wants to use this plugin or not.

Author

Matthias Kretz kretz[email protected]@kde[email protected].org

Deprecated:

since 5.88, use QPluginLoader or the KPluginFactory::loadFactory/KPluginFactory::instantiatePlugins methods instead to create objects from the plugins. For accessing the metadata, use KPluginMetaData instead. To embed json metadata in your plugin, use K_PLUGIN_CLASS_WITH_JSON(MyClass, "mypluginmetadata.json")

The reading of the enabled state can be done using the KPluginMetaData::isEnabled method. Writing the config should be done manually. Consider using KPluginWidget for the configuration of plugins in the UI.

Constructor & Destructor Documentation

KPluginInfo() [1/6]

KPluginInfo::KPluginInfo ( const QString &  filename )

explicit

Read plugin info from filename.

The file should be of the following form:

KPluginInfo() [3/6]

KPluginInfo::KPluginInfo ( const QVariantList &  args, const QString &  libraryPath = QString()  )

explicit

Read plugin info from arguments passed to the plugin.

These arguments should contain the plugin's metadata (as read from QPluginLoader::metaData(). This constructor uses the metadata read from the QVariantList. It reads the first QVariantMap it finds in a field called "MetaData".

Use (Q|K)PluginLoader and build the metadata into the plugin using K_PLUGIN_CLASS_WITH_JSON( ..., "mypluginmetadata.json")

You can use the "desktoptojson tool to generate a .json file from your .desktop file. The .json file should look like this:

 {
     "Comment": "Date and time by timezone",
     "Icon": "preferences-system-time",
     "Name": "Date and Time",
     "Type": "Service",

     "X-KDE-PluginInfo-Depends": [
     ],
     "X-KDE-PluginInfo-Email": "[email protected]",

     "X-KDE-PluginInfo-License": "LGPL",
     "X-KDE-PluginInfo-Name": "time",
     "X-KDE-PluginInfo-Version": "1.0",
     "X-KDE-PluginInfo-Website": "http://plasma.kde.org/",
     "X-KDE-ServiceTypes": [
         "Plasma/DataEngine"
     ],
     "X-KDE-FormFactors": [
         "tablet",
         "handset"
     ]
 }

Parameters

args	QVariantList with arguments, should contain a QVariantMap, keyed "MetaData" as provided by QPluginLoader::metaData()
libraryPath	The path to the plugin file on disk
