Constructor & Destructor Documentation

KPluginInfo::KPluginInfo ( const QString &  filename)
explicit

Read plugin info from filename.

The file should be of the following form: 

[Desktop Entry]

X-KDE-PluginInfo-License=GPL
X-KDE-PluginInfo-EnabledByDefault=true

The Name and Comment fields must always be present.

The "X-KDE-PluginInfo" keys you may add further entries which will be available using property(). The Website,Category,Require keys are optional. For EnabledByDefault look at isPluginEnabledByDefault.

Parameters
filenameThe filename of the .desktop file.
resourceIf filename is relative, you need to specify a resource type (e.g. "service", "apps"... KStandardDirs). Otherwise, resource isn't used.

Definition at line 239 of file kplugininfo.cpp.

KPluginInfo::KPluginInfo ( const KService::Ptr  service)
explicit

Read plugin info from a KService object.

The .desktop file should look like this: 

[Desktop Entry]

Deprecated:
since 5.0, use (Q|K)PluginLoader instead and build the metadata into the plugin using K_PLUGIN_CLASS_WITH_JSON( ..., "mypluginmetadata.json")

Definition at line 287 of file kplugininfo.cpp.

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-EnabledByDefault": true,
     "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-FormFactors": [
         "tablet",
         "handset"
     ]
 }
Parameters
argsQVariantList with arguments, should contain a QVariantMap, keyed "MetaData" as provided by QPluginLoader::metaData()
