Detailed Description

This is an abstract base class which defines an interface to which Plasma's Applet Loading logic can communicate with a parent application.

The plugin loader must be set before any plugins are loaded, otherwise (for safety reasons), the default PluginLoader implementation will be used. The reimplemented version should not do more than simply returning a loaded plugin. It should not init() it, and it should not hang on to it. The associated methods will be called only when a component of Plasma needs to load a new plugin.

listAppletMetaData()

QList< KPluginMetaData > Plasma::PluginLoader::listAppletMetaData

(

const QString &

category

)

Returns a list of all known applets.

This may skip applets based on security settings and ExcludeCategories in the application's config.

Parameters

category

Only applets matching this category will be returned. If "Misc" is passed in, then applets without a Categories= entry are also returned. If an empty string is passed in, all applets are returned.

Returns

list of applets

Since

5.28

Definition at line 129 of file pluginloader.cpp.

listAppletMetaDataForMimeType()

QList< KPluginMetaData > Plasma::PluginLoader::listAppletMetaDataForMimeType

(

const QString &

mimetype

)

Returns a list of all known applets associated with a certain mimetype.

Returns

list of applets

Since

5.36

Definition at line 188 of file pluginloader.cpp.

listAppletMetaDataForUrl()

QList< KPluginMetaData > Plasma::PluginLoader::listAppletMetaDataForUrl

(

const QUrl &

url

)

Returns a list of all known applets associated with a certain URL.

Returns

list of applets

Since

5.36

Definition at line 196 of file pluginloader.cpp.

listContainmentActionsMetaData()

QList< KPluginMetaData > Plasma::PluginLoader::listContainmentActionsMetaData

(

const QString &

parentApp

)

Returns a list of all known ContainmentActions.

Parameters

parentApp

the application to filter ContainmentActions on. Uses the X-KDE-ParentApp entry (if any) in the plugin metadata. The default value of QString() will result in a list of all ContainmentActions.

Returns

list of ContainmentActions

Since

5.77

Definition at line 235 of file pluginloader.cpp.

listContainmentsMetaData()

QList< KPluginMetaData > Plasma::PluginLoader::listContainmentsMetaData ( std::function< bool(const KPluginMetaData &)> filter = {} )

static

Returns a list of all known containments.

Parameters

filter

An optional predicate that can be used for filtering.

Returns

list of containments

Definition at line 217 of file pluginloader.cpp.

listContainmentsMetaDataOfType()

QList< KPluginMetaData > Plasma::PluginLoader::listContainmentsMetaDataOfType ( const QString & type )

static

Returns a list of containments of the specified type.

Parameters

type	The target containment type

Returns

list of containments

Definition at line 226 of file pluginloader.cpp.

loadApplet()

Applet * Plasma::PluginLoader::loadApplet	(	const QString &	name,
		uint	appletId = 0,
		const QVariantList &	args = QVariantList() )

Load an Applet plugin.

Parameters

name	the plugin name, as returned by KPluginInfo::pluginName()
appletId	unique ID to assign the applet, or zero to have one assigned automatically.
args	to send the applet extra arguments

Returns

a pointer to the loaded applet, or 0 on load failure

Definition at line 41 of file pluginloader.cpp.

loadContainmentActions()

ContainmentActions * Plasma::PluginLoader::loadContainmentActions	(	Containment *	parent,
		const QString &	containmentActionsName,
		const QVariantList &	args = QVariantList() )

Load a ContainmentActions plugin.

Returns a pointer to the containmentactions if successful. The caller takes responsibility for the containmentactions, including deleting it when no longer needed.

Parameters

parent

the parent containment.

Since

4.6 null is allowed.

Parameters

name	the plugin name, as returned by KPluginInfo::pluginName()
args	to send the containmentactions extra arguments

Returns

a ContainmentActions object

Definition at line 110 of file pluginloader.cpp.

self()

PluginLoader * Plasma::PluginLoader::self ( )

static

Return the active plugin loader.
