Detailed Description
Encapsulates a KCModule for embedding.
KCModuleProxy is a wrapper for KCModule intended for cases where modules are to be displayed. It ensures layout is consistent, handles root/administrator modules and in general takes care of the details needed for making a module available in an interface. A KCModuleProxy can be treated as a QWidget, without worrying about the details specific for modules such as library loading. KCModuleProxy is not a sub class of KCModule but its API closely resembles KCModule's.
Usually, an instance is created by passing one of the constructors a KService::Ptr, KCModuleInfo or simply the name of the module and then added to the layout as any other widget.
When the user have changed the module, changed( bool ) as well as changed ( KCModuleProxy * ) is emitted. KCModuleProxy does not take care of prompting for saving - if the object is deleted while changes is not saved the changes will be lost. changed() returns true if changes are unsaved.
KCModuleProxy does not take care of authorization of KCModules.
KCModuleProxy do lazy loading, meaning the library will not be loaded or any other initialization done before its show() function is called. This means modules will only be loaded when they are actually needed as well as it is possible to load many KCModuleProxy without any speed penalty.
KCModuleProxy should be used in all cases where modules are embedded in order to promote code efficiency and usability consistency.

KCModuleProxy::KCModuleProxy | ( | const KCModuleInfo & | info, | |

|||
QWidget * | parent = 0 , |
|||
const char * | name = 0 , |
|||
const QStringList & | args = QStringList() | |||
) |
Constructs a KCModuleProxy from a KCModuleInfo class.
- Parameters:
-
info The KCModuleInfo to construct the module from. withFallback If set to true and loading of the module fails, a alternative will be tried, resulting in the module appearing in its own window, if at all. The embedded module will be load()ed. parent the parent QWidget. name the module's name. args This is used in the implementation and is internal. Use the default.
Definition at line 482 of file kcmoduleproxy.cpp.
KCModuleProxy::KCModuleProxy | ( | const QString & | serviceName, | |
bool | withFallback = true , |
|||
QWidget * | parent = 0 , |
|||
const char * | name = 0 , |
|||
const QStringList & | args = QStringList() | |||
) |
Constructs a KCModuleProxy from a module's service name, which is equivalent to the desktop file for the kcm without the ".desktop" part.
Otherwise equal to the one above.
- Parameters:
-
serviceName The module's service name to construct from. withFallback If set to true and loading of the module fails, a alternative will be tried, resulting in the module appearing in its own window, if at all. The embedded module will be load()ed. parent the parent QWidget. name the module's name. args This is used in the implementation and is internal. Use the default.

bool | withFallback = true , |
|||
QWidget * | parent = 0 , |
|||
const char * | name = 0 , |
|||
const QStringList & | args = QStringList() | |||
) |
Constructs a KCModuleProxy from KService.
Otherwise equal to the one above.
- Parameters:
-
service The KService to construct from. withFallback If set to true and loading of the module fails, a alternative will be tried, resulting in the module appearing in its own window, if at all. The embedded module will be load()ed. parent the parent QWidget. name the module's name. args This is used in the implementation and is internal. Use the default.

Member Function Documentation
const KAboutData * KCModuleProxy::aboutData | ( | ) | const |
int KCModuleProxy::buttons | ( | ) | const |
void KCModuleProxy::changed | ( | KCModuleProxy * | mod | ) | [signal] |
This is emitted in the same situations as in the one above.
Practical when several KCModuleProxys are loaded.
- Since:
- 3.4
void KCModuleProxy::changed | ( | bool | state | ) | [signal] |
bool KCModuleProxy::changed | ( | ) | const |
- Returns:
- true if the module is modified and needs to be saved.
Definition at line 621 of file kcmoduleproxy.cpp.
void KCModuleProxy::childClosed | ( | ) | [signal] |
When a module running with root privileges and exits, returns to normal mode, the childClosed() signal is emitted.
- Since:
- 3.4
QCString KCModuleProxy::dcopName | ( | ) | const |
Returns the DCOP the module's DCOPClient and DCOPObject has(they are identical).
- Since:
- 3.4
Definition at line 636 of file kcmoduleproxy.cpp.
void KCModuleProxy::defaults | ( | ) | [slot] |
Calling it will cause the contained module to load its default values.
Definition at line 551 of file kcmoduleproxy.cpp.
void KCModuleProxy::deleteClient | ( | ) | [slot] |
Calling this, results in deleting the contained module, and unregistering from DCOP.
A similar result is achieved by deleting the KCModuleProxy itself.
- Since:
- 3.4
Definition at line 436 of file kcmoduleproxy.cpp.
void KCModuleProxy::emitQuickHelpChanged | ( | ) | [protected] |
void KCModuleProxy::init | ( | const KCModuleInfo & | info | ) | [protected] |
Internal intialization function, called by the constructors.
For internal use only.
- Since:
- 3.4
Definition at line 501 of file kcmoduleproxy.cpp.
KInstance * KCModuleProxy::instance | ( | ) | const |
Returns the embedded KCModule's KInstance.
- Returns:
- The module's KInstance.
Definition at line 616 of file kcmoduleproxy.cpp.
void KCModuleProxy::load | ( | ) |
Calling it will cause the contained module to run its load() routine.
Definition at line 515 of file kcmoduleproxy.cpp.
const KCModuleInfo & KCModuleProxy::moduleInfo | ( | ) | const |
- Returns:
- a KCModuleInfo for the encapsulated module
Definition at line 626 of file kcmoduleproxy.cpp.
QString KCModuleProxy::quickHelp | ( | ) | const |
void KCModuleProxy::quickHelpChanged | ( | ) | [signal] |
KCModule * KCModuleProxy::realModule | ( | ) | const |
Access to the actual module.
However, if the module is running in root mode, see rootMode(), this function returns a NULL pointer, since the module is in another process. It may also return NULL if anything goes wrong.
- Returns:
- the encapsulated module.
Definition at line 140 of file kcmoduleproxy.cpp.
bool KCModuleProxy::rootMode | ( | ) | const |
Returns whether the module is running in root mode.
A module is in root mode when runAsRoot() has been called. A session under root user will never reach root mode.
- Note:
- realModule() will return null when the module is running in root mode.
- Returns:
- true if the module is running with root privileges
- Since:
- 3.4
Definition at line 631 of file kcmoduleproxy.cpp.
QString KCModuleProxy::rootOnlyMsg | ( | ) | const |
- Returns:
- The module's custom root message, if it has one
Definition at line 606 of file kcmoduleproxy.cpp.
void KCModuleProxy::runAsRoot | ( | ) | [slot] |
Calling this will cause the module to be run in "administrator mode".
- Since:
- 3.4
Definition at line 298 of file kcmoduleproxy.cpp.
void KCModuleProxy::save | ( | ) |
Calling it will cause the contained module to run its save() routine.
If the module was not modified, it will not be asked to save.
Definition at line 527 of file kcmoduleproxy.cpp.
void KCModuleProxy::showEvent | ( | QShowEvent * | ev | ) | [protected] |
Reimplemented for internal purposes.
Makes sure the encapsulated module is loaded before the show event is taken care of.
Reimplemented from QWidget.
