Member Function Documentation

◆ action()

QAction * Plasma::Corona::action ( const QString & name) const
Returns
The action with the given name, if any

Definition at line 397 of file corona.cpp.

◆ actions()

QList< QAction * > Plasma::Corona::actions ( ) const
Returns
all the actions supported by the corona

Definition at line 427 of file corona.cpp.

◆ availableScreenRect()

QRect Plasma::Corona::availableScreenRect ( int id) const
virtual

Returns the available rect for a given screen.

The difference between this and availableScreenRegion() is that this method returns only a rectangular available space (it doesn't care if your panel is not 100% width). The available rect excludes panels and similar windows. Valid screen ids are 0 to numScreens()-1. By default this method returns a rectangular region equal to screenGeometry(id); subclasses that need another behavior should override this method.

Definition at line 272 of file corona.cpp.

◆ availableScreenRectChanged

void Plasma::Corona::availableScreenRectChanged ( int id)
signal

This signal indicates that a change in available screen geometry occurred.

◆ availableScreenRegion()

QRegion Plasma::Corona::availableScreenRegion ( int id) const
virtual

Returns the available region for a given screen.

The available region excludes panels and similar windows. Valid screen ids are 0 to numScreens()-1. By default this method returns a rectangular region equal to screenGeometry(id); subclasses that need another behavior should override this method.

Definition at line 267 of file corona.cpp.

◆ availableScreenRegionChanged

void Plasma::Corona::availableScreenRegionChanged ( int id)
signal

This signal indicates that a change in available screen geometry occurred.

◆ config()

KSharedConfigPtr Plasma::Corona::config ( ) const

Returns the config file used to store the configuration for this Corona.

Definition at line 230 of file corona.cpp.

◆ configSynced

void Plasma::Corona::configSynced ( )
signal

This signal indicates that the configuration file was flushed to disk.

◆ containmentAdded

void Plasma::Corona::containmentAdded ( Plasma::Containment * containment)
signal

This signal indicates a new containment has been added to the Corona: it may occur after creation or restore from config.

◆ containmentCreated

void Plasma::Corona::containmentCreated ( Plasma::Containment * containment)
signal

This signal indicates a new containment has been created in the Corona.

Compared to containmentAdded it can only happen after the creation of a new containment.

const QString & activity,
const QString & defaultPluginIfNonExistent,
const QVariantList & defaultArgs = QVariantList() )

Returns the Containment for a given physical screen and desktop, creating one if none exists.

Parameters
screennumber of the physical screen to locate
activitythe activity id of the containment we want, and empty string if the activity is not important
defaultPluginIfNonExistentthe plugin to load by default; "null" won't create it and "default" creates the default plugin
defaultArgsoptional arguments to pass in when creating a Containment if needed
Since
5.45

Definition at line 157 of file corona.cpp.

◆ containments()

QList< Containment * > Plasma::Corona::containments ( ) const
Returns
all containments on this Corona

Definition at line 220 of file corona.cpp.

◆ containmentsForActivity()

QList< Containment * > Plasma::Corona::containmentsForActivity ( const QString & activity)

Returns all containments which match a particular activity, for any screen.

Parameters
activitythe activity id we want
Returns
the list of matching containments if any, empty if activity is an empty string
Since
5.45

Definition at line 187 of file corona.cpp.

◆ containmentsForScreen()

QList< Containment * > Plasma::Corona::containmentsForScreen ( int screen)

Returns all containments which match a particular screen, for any activity.

Parameters
screenthe screen number we want
Returns
the list of matching containments if any, empty if screen is < 0
Since
5.45

Definition at line 203 of file corona.cpp.

◆ createContainment()

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

Adds a Containment to the Corona.

Parameters
namethe 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.
argsargument 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. If the requested containment plugin can not be located or successfully loaded, the Containment will have an invalid pluginInfo().

Definition at line 239 of file corona.cpp.

◆ createContainmentDelayed()

Containment * Plasma::Corona::createContainmentDelayed ( const QString & name,
const QVariantList & args = QVariantList() )
protected

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

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

Parameters
namethe 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.
argsargument 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.

signal

this is for use by things that don't get constraints events, like plasmaapp. it's NOT for containments or applets or any of the other stuff on the scene. if your code's not in shells/ it probably shouldn't be using it.
