Member Function Documentation
◆ action()
- Returns
- The action with the given name, if any
Definition at line 397 of file corona.cpp.
◆ actions()
- Returns
- all the actions supported by the corona
Definition at line 427 of file corona.cpp.
◆ availableScreenRect()
|
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
|
signal |
This signal indicates that a change in available screen geometry occurred.
◆ availableScreenRegion()
|
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
|
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
|
signal |
This signal indicates that the configuration file was flushed to disk.
◆ containmentAdded
|
signal |
This signal indicates a new containment has been added to the Corona: it may occur after creation or restore from config.
◆ containmentCreated
|
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.

- containmentAdded
- Since
- 5.16
◆ containmentForScreen()
Containment * Plasma::Corona::containmentForScreen | ( | int | screen, |
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
-
screen number of the physical screen to locate activity the activity id of the containment we want, and empty string if the activity is not important defaultPluginIfNonExistent the plugin to load by default; "null" won't create it and "default" creates the default plugin defaultArgs optional 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
-
activity the 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
-
screen the 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
-
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. 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()
|
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
-
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 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 248 of file corona.cpp.
◆ editModeChanged
|
signal |
◆ exportLayout()
void Plasma::Corona::exportLayout | ( | KConfigGroup & | config, |
QList< Containment * > | containments ) |
Exports a set of containments to a config file.
- Parameters

- Since
- 4.6
Definition at line 74 of file corona.cpp.
◆ freeEdges()
QList< Plasma::Types::Location > Plasma::Corona::freeEdges | ( | int | screen | ) | const |
This method is useful in order to retrieve the list of available screen edges for panel type containments.
- Parameters
-
screen the id of the screen to look for free edges.

Definition at line 377 of file corona.cpp.

|
signal |
emitted when immutability changes.
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.
◆ importLayout()
QList< Plasma::Containment * > Plasma::Corona::importLayout | ( | const KConfigGroup & | config | ) |
Imports an applet layout from a config file.
The results will be added to the current set of Containments.

Definition at line 225 of file corona.cpp.
◆ kPackage()
KPackage::Package Plasma::Corona::kPackage | ( | ) | const |
Accessor for the associated Package object if any.
A Corona package defines how Containments are laid out in a View, ToolBoxes, default layout, error messages and in general all the furniture specific of a particular device form factor.
- Returns

- Since
- 5.5
Definition at line 50 of file corona.cpp.

config the name of the config file to load from, or the default config file if QString()
Definition at line 132 of file corona.cpp.
◆ numScreens()
|
virtual |
Returns the number of screens available to plasma.

slot |
Schedules a time sensitive flush-to-disk synchronization of the configuration state.
Since this method does not provide any sort of event compression, it should only be used when an immediate disk sync is absolutely required. Otherwise, use
- See also
- requestConfigSync() which does do event compression.
Definition at line 127 of file corona.cpp.
