Member Function Documentation

QAction * Plasma::Corona::action ( QString name ) const

Returns the QAction with the given name from our collection.

Definition at line 716 of file corona.cpp.

QList< QAction * > Plasma::Corona::actions ( ) const

Returns all the actions in our collection.

Definition at line 731 of file corona.cpp.

void Plasma::Corona::addAction	(	QString	name,
		QAction *	action
	)

Adds the action to our collection under the given name.

Definition at line 721 of file corona.cpp.

KAction * Plasma::Corona::addAction ( QString name )

Since: 4.3 Creates an action in our collection under the given name

Returns: the new action FIXME I'm wrapping so much of kactioncollection API now, maybe I should just expose the collection itself :P

Definition at line 726 of file corona.cpp.

Containment * Plasma::Corona::addContainment	(	const QString &	name,
		const QVariantList &	args = `QVariantList()`
	)

Adds a Containment to the Corona.

Parameters

name	the plugin name for the containment, as given by KPluginInfo::pluginName(). If an empty string is passed in, the default containment plugin will be used (usually DesktopContainment). If the string literal "null" is passed in, then no plugin will be loaded and a simple Containment object will be created instead.
args	argument list to pass to the containment

Returns: a pointer to the containment on success, or 0 on failure. Failure can be caused by too restrictive of an Immutability type, as containments cannot be added when widgets are locked, or if the requested containment plugin can not be located or successfully loaded.

Definition at line 349 of file corona.cpp.

Containment * Plasma::Corona::addContainmentDelayed	(	const QString &	name,
		const QVariantList &	args = `QVariantList()`
	)

Loads a containment with delayed initialization, primarily useful for implementations of loadDefaultLayout.

The caller is responsible for all initializating, saving and notification of a new containment.

Parameters

name	the plugin name for the containment, as given by KPluginInfo::pluginName(). If an empty string is passed in, the defalt containment plugin will be used (usually DesktopContainment). If the string literal "null" is passed in, then no plugin will be loaded and a simple Containment object will be created instead.
args	argument list to pass to the containment

Returns: a pointer to the containment on success, or 0 on failure. Failure can be caused by the Immutability type being too restrictive, as containments can't be added when widgets are locked, or if the requested containment plugin can not be located or successfully loaded.

See also: addContainment

Definition at line 358 of file corona.cpp.

void Plasma::Corona::addOffscreenWidget ( QGraphicsWidget * widget )
