Member Function Documentation
Returns the QAction with the given name from our collection.
Definition at line 765 of file corona.cpp.
Returns all the actions in our collection.
Definition at line 780 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 775 of file corona.cpp.
Adds the action to our collection under the given name.
Definition at line 770 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 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
Definition at line 465 of file corona.cpp.
| Containment * Plasma::Corona::addContainmentDelayed | ( | 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 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
Definition at line 470 of file corona.cpp.
| void Plasma::Corona::addOffscreenWidget | ( | QGraphicsWidget * | widget | ) |
Adds a widget in the topleft quadrant in the scene.
Widgets in the topleft quadrant are normally never shown unless you specifically aim a view at it, which makes it ideal for toplevel views etc.
- Parameters:
-
widget the widget to add.
Definition at line 475 of file corona.cpp.
| void Plasma::Corona::addShortcuts | ( | KActionCollection * | newShortcuts | ) |
- Since:
- 4.3 Adds a set of actions to the shortcut config dialog. don't use this on actions in the corona's own actioncollection, those are handled automatically. this is for stuff outside of that.
Definition at line 800 of file corona.cpp.

Definition at line 294 of file corona.cpp.
| 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 550 of file corona.cpp.
| void Plasma::Corona::availableScreenRegionChanged | ( | ) | [signal] |
This signal inicates that a change in available screen goemetry occurred.

Definition at line 708 of file corona.cpp.
| void Plasma::Corona::immutabilityChanged | ( | Plasma::ImmutabilityType | immutability | ) | [signal] |
emitted when immutability changes.
this is for use by things that don't get contraints 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.
Initializes the layout from a config file.
This will first clear any existing Containments, load a layout from the requested configuration file, request the default layout if needed and update immutability.
- Parameters:
-
config the name of the config file to load from, or the default config file if QString()
Definition at line 331 of file corona.cpp.
| void Plasma::Corona::loadDefaultLayout | ( | ) | [protected, virtual] |
Loads the default (system wide) layout for this user.
Definition at line 689 of file corona.cpp.
Load applet layout from a config file.
The results will be added to the current set of Containments.
- Parameters:
-
config the name of the config file to load from, or the default config file if QString()
Definition at line 351 of file corona.cpp.
| int Plasma::Corona::numScreens | ( | ) | const [virtual] |

Definition at line 312 of file corona.cpp.
| void Plasma::Corona::requireConfigSync | ( | ) | [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 326 of file corona.cpp.
Save applets layout to file.

- Since:
- 4.3 emitted when the user changes keyboard shortcut settings connect to this if you've put some extra shortcuts in your app that are NOT in corona's actioncollection. if your code's not in shells/ it probably shouldn't be using this function.
- See also:
- addShortcuts
| void Plasma::Corona::updateShortcuts | ( | ) |
- Since:
- 4.3 Updates keyboard shortcuts for all the corona's actions. If you've added actions to the corona you'll need to call this for them to be configurable.
