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 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 has 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 implements 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.

Constructor & Destructor Documentation

KCModuleProxy::KCModuleProxy ( const KCModuleInfo &  info,
QWidget *  parent = 0,
const QStringList &  args = QStringList() 
) [explicit]

Constructs a KCModuleProxy from a KCModuleInfo class.

Parameters:
info The KCModuleInfo to construct the module from.
parent the parent QWidget.
args This is used in the implementation and is internal. Use the default.

Definition at line 243 of file kcmoduleproxy.cpp.

KCModuleProxy::KCModuleProxy ( const QString &  serviceName,
QWidget *  parent = 0,
const QStringList &  args = QStringList() 
) [explicit]

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.
parent the parent QWidget.
args This is used in the implementation and is internal. Use the default.

Definition at line 250 of file kcmoduleproxy.cpp.

KCModuleProxy::KCModuleProxy ( const KService::Ptr &  service,
QWidget *  parent = 0,
const QStringList &  args = QStringList() 
) [explicit]

Constructs a KCModuleProxy from KService.

Otherwise equal to the one above.

Parameters:
service The KService to construct from.
parent the parent QWidget.
args This is used in the implementation and is internal. Use the default.

Definition at line 236 of file kcmoduleproxy.cpp.

KCModuleProxy::~KCModuleProxy (  ) 

Default destructor.

Definition at line 202 of file kcmoduleproxy.cpp.


Member Function Documentation

const KAboutData * KCModuleProxy::aboutData (  )  const
Returns:
the module's aboutData()

Definition at line 290 of file kcmoduleproxy.cpp.

KCModule::Buttons KCModuleProxy::buttons (  )  const
Returns:
what buttons the module needs

Definition at line 295 of file kcmoduleproxy.cpp.

void KCModuleProxy::changed ( KCModuleProxy *  mod  )  [signal]

This is emitted in the same situations as in the one above.

Practical when several KCModuleProxys are loaded.

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 317 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.

KComponentData KCModuleProxy::componentData (  )  const

Returns the embedded KCModule's KComponentData.

Returns:
The module's KComponentData.
Deprecated:

Definition at line 312 of file kcmoduleproxy.cpp.

QString KCModuleProxy::dbusPath (  )  const

Returns the DBUS Path.

Definition at line 335 of file kcmoduleproxy.cpp.

QString KCModuleProxy::dbusService (  )  const

Returns the DBUS Service name.

Definition at line 329 of file kcmoduleproxy.cpp.

void KCModuleProxy::defaults (  )  [slot]

Calling it will cause the contained module to load its default values.

Definition at line 278 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.

Definition at line 210 of file kcmoduleproxy.cpp.

void KCModuleProxy::load (  ) 

Calling it will cause the contained module to run its load() routine.

Definition at line 258 of file kcmoduleproxy.cpp.

QSize KCModuleProxy::minimumSizeHint (  )  const

Returns the recommended minimum size for the widget.

Definition at line 341 of file kcmoduleproxy.cpp.

KCModuleInfo KCModuleProxy::moduleInfo (  )  const
Returns:
a KCModuleInfo for the encapsulated module

Definition at line 323 of file kcmoduleproxy.cpp.

QString KCModuleProxy::quickHelp (  )  const
Returns:
the module's quickHelp();

Definition at line 285 of file kcmoduleproxy.cpp.

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 69 of file kcmoduleproxy.cpp.

QString KCModuleProxy::rootOnlyMessage (  )  const
Returns:
The module's custom root message, if it has one
Deprecated:

Definition at line 302 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 268 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.

Definition at line 187 of file kcmoduleproxy.cpp.

bool KCModuleProxy::useRootOnlyMessage (  )  const
Returns:
If the module is a root module.
Deprecated:

Definition at line 307 of file kcmoduleproxy.cpp.
