Detailed Description

The base class for configuration modules.

Configuration modules are realized as plugins that are loaded only when needed.

The module in principle is a simple widget displaying the item to be changed. The module has a very small interface.

All the necessary glue logic and the GUI bells and whistles are provided by the control center and must not concern the module author.

To write a config module, you have to create a library that contains a factory function like the following:

#include <KPluginFactory>
 
K_PLUGIN_FACTORY(MyKCModuleFactory, registerPlugin<MyKCModule>() )

The constructor of the KCModule then looks like this:

YourKCModule::YourKCModule( QWidget* parent )
  : KCModule( parent )
{
  KAboutData *about = new KAboutData(
    <kcm name>, i18n( "..." ),
    KDE_VERSION_STRING, QString(), KAboutLicense::GPL,
    i18n( "Copyright 2006 ..." ) );
  about->addAuthor( i18n(...) );
  setAboutData( about );
  .
  .
  .
}

If you want to make the KCModule available only conditionally (i.e. show in the list of available modules only if some test succeeds) then you can use Hidden in the .desktop file. An example:

Hidden[$e]=$(if test -e /dev/js*; then echo "false"; else echo "true"; fi)

The example executes the given code in a shell and uses the stdout output for the Hidden value (so it's either Hidden=true or Hidden=false).

See http://techbase.kde.org/Development/Tutorials/KCM_HowTo for more detailed documentation.

Member Typedef Documentation

◆ Buttons

typedef QFlags< Button > KCModule::Buttons

Stores a combination of Button values.

Definition at line 100 of file kcmodule.h.

Member Enumeration Documentation

◆ Button

enum KCModule::Button

An enumeration type for the buttons used by this module.

You should only use Help, Default and Apply. The rest is obsolete. NoAdditionalButton can be used when we do not want have other button that Ok Cancel

See also: KCModule::buttons; KCModule::setButtons; Buttons

Definition at line 96 of file kcmodule.h.

Constructor & Destructor Documentation

◆ KCModule() [1/2]

KCModule::KCModule	(	const KAboutData *	aboutData,
		QWidget *	parent = `nullptr`,
		const QVariantList &	args = `QVariantList()`
	)

explicit

Base class for all KControlModules.

Note: do not emit changed signals here, since they are not yet connected to any slot.

Parameters

aboutData becomes owned by the KCModule

Deprecated:: since 5.85, use other constructor and setAboutData()

Definition at line 68 of file kcmodule.cpp.

◆ KCModule() [2/2]

KCModule::KCModule	(	QWidget *	parent = `nullptr`,
		const QVariantList &	args = `QVariantList()`
	)

explicit

Base class for all KControlModules.

Note: do not emit changed signals here, since they are not yet connected to any slot.

Definition at line 76 of file kcmodule.cpp.

◆ ~KCModule()

KCModule::~KCModule ( )

override

Destroys the module.

Definition at line 210 of file kcmodule.cpp.

Member Function Documentation

◆ aboutData()

const KAboutData * KCModule::aboutData ( ) const

virtual

This is generally only called for the KBugReport.

If you override you should have it return a pointer to a constant.

Returns: the KAboutData for this module

Deprecated:: since 5.90. Use the KPluginMetaData the KCModule was instantiated from.

Definition at line 286 of file kcmodule.cpp.

◆ addConfig() [1/2]

KConfigDialogManager * KCModule::addConfig	(	KConfigSkeleton *	config,
		QWidget *	widget
	)

protected

Adds a KConfigskeleton config to watch the widget widget.

This function is useful if you need to handle multiple configuration files.

Returns: a pointer to the KConfigDialogManager in use

Parameters

config	the KConfigSkeleton to use
widget	the widget to watch

Deprecated:: since 5.84, use addConfig(KCoreConfigSkeleton *config, QWidget *widget);

Definition at line 119 of file kcmodule.cpp.

◆ addConfig() [2/2]

KConfigDialogManager * KCModule::addConfig	(	KCoreConfigSkeleton *	config,
		QWidget *	widget
	)

protected

Adds a KCoreConfigskeleton config to watch the widget widget.

This function is useful if you need to handle multiple configuration files.

Returns: a pointer to the KCoreConfigDialogManager in use

Parameters

config	the KCoreConfigSkeleton to use
widget	the widget to watch

Definition at line 106 of file kcmodule.cpp.

◆ buttons()

KCModule::Buttons KCModule::buttons ( ) const

Indicate which buttons will be used.

The return value is a value or'ed together from the Button enumeration type.

See also: KCModule::setButtons

Definition at line 96 of file kcmodule.cpp.

◆ changed [1/2]

void KCModule::changed ( )

protectedslot

Calling this slot is equivalent to emitting changed(true).

Deprecated:: Since 5.64, use markAsChanged

Definition at line 323 of file kcmodule.cpp.

◆ changed [2/2]

void KCModule::changed ( bool state )

signal

Indicate that the state of the modules contents has changed.

This signal is emitted whenever the state of the configuration shown in the module changes. It allows the module container to keep track of unsaved changes.

◆ componentData()

KAboutData KCModule::componentData ( ) const

Deprecated:: since 5.90.

Use the KPluginMetaData the KCModule was instantiated from.

Definition at line 335 of file kcmodule.cpp.

◆ configs()

QList< KConfigDialogManager * > KCModule::configs ( ) const

Returns: a list of KConfigDialogManager's in use, if any.

Definition at line 366 of file kcmodule.cpp.

◆ defaulted

void KCModule::defaulted ( bool state )

signal

Indicate that the state of the modules contents matches the default settings.

This signal is emitted whenever the state of the configuration shown in the module changes. It allows the module container to keep track of defaults.

Since: 5.65

◆ defaults

void KCModule::defaults ( )

virtualslot

Sets the configuration to sensible default values.

This method is called when the user clicks the "Default" button. It should set the display to useful values.

If you use KConfigXT, you do not have to reimplement this function since the fetching and settings of default values is done automatically. However, if you reimplement and also are using KConfigXT, remember to call the base function at the very end of your reimplementation.

Reimplemented in KCModuleContainer.

Definition at line 233 of file kcmodule.cpp.

◆ defaultsIndicatorsVisible()

bool KCModule::defaultsIndicatorsVisible ( ) const

Returns whether an indicator is shown when a setting differs from default.

Since: 5.73

Definition at line 166 of file kcmodule.cpp.

◆ defaultsIndicatorsVisibleChanged

void KCModule::defaultsIndicatorsVisibleChanged ( bool show )

signal

Emitted when show defaults indicators changed.

Since: 5.73

◆ exportText()

QString KCModule::exportText ( ) const

Returns the value set by setExportText();.

Deprecated:: since 5.0, obsolete feature

Definition at line 342 of file kcmodule.cpp.

◆ load

void KCModule::load ( )

virtualslot

Load the configuration data into the module.

The load method sets the user interface elements of the module to reflect the current settings stored in the configuration files.

This method is invoked whenever the module should read its configuration (most of the times from a config file) and update the user interface. This happens when the user clicks the "Reset" button in the control center, to undo all of his changes and restore the currently valid settings. It is also called right after construction.

Reimplemented in KCModuleContainer, and KSettings::PluginPage.

Definition at line 217 of file kcmodule.cpp.

◆ managedWidgetChangeState()

bool KCModule::managedWidgetChangeState ( ) const

protected

Returns the changed state of automatically managed widgets in this dialog.

Definition at line 250 of file kcmodule.cpp.

◆ managedWidgetDefaultState()

bool KCModule::managedWidgetDefaultState ( ) const

protected

Returns the defaulted state of automatically managed widgets in this dialog.

Since: 5.65

Definition at line 261 of file kcmodule.cpp.

◆ markAsChanged

void KCModule::markAsChanged ( )

protectedslot

Calling this slot is equivalent to emitting changed(true).

Since: 5.64

Definition at line 329 of file kcmodule.cpp.

◆ needsAuthorization()

bool KCModule::needsAuthorization ( ) const

Returns the value previously set with setNeedsAuthorization() or setAuthAction().

By default it's false.

Returns: true if the module's save() method requires authorization, false otherwise

Definition at line 148 of file kcmodule.cpp.

◆ quickHelp()

QString KCModule::quickHelp ( ) const

virtual

Return a quick-help text.

This method may be called when the module is docked. The quick help would generally be used as "what's this" text if the view container supports the "what's this" system. The quick-help text should contain a short description of the module and links to the module's help files. You can use QML formatting tags in the text.

Note: make sure the quick help text gets translated (use i18n()).

Definition at line 361 of file kcmodule.cpp.

◆ quickHelpChanged

void KCModule::quickHelpChanged ( )

signal

Indicate that the module's quickhelp has changed.

Emit this signal whenever the module's quickhelp changes. Modules implemented as tabbed dialogs might want to implement per-tab quickhelp for example.

◆ rootOnlyMessage()

QString KCModule::rootOnlyMessage ( ) const

Get the RootOnly message for this module.

When the module must be run as root, or acts differently for root and a normal user, it is sometimes useful to customize the message that appears at the top of the module when used as a normal user. This function returns this customized message. If none has been set, a default message will be used.

See also: KCModule::setRootOnlyMessage

Definition at line 306 of file kcmodule.cpp.

◆ rootOnlyMessageChanged

void KCModule::rootOnlyMessageChanged	(	bool	use,
		QString	message
	)

signal

Indicate that the module's root message has changed.

Emits this signal whenever the module's root message changes.

Since: 4.4

◆ save

void KCModule::save ( )

virtualslot

Save the configuration data.

The save method stores the config information as shown in the user interface in the config files.

If necessary, this method also updates the running system, e.g. by restarting applications. This normally does not apply for KSettings::Dialog modules where the updating is taken care of by KSettings::Dispatcher.

save is called when the user clicks "Apply" or "Ok".

If you use KConfigXT, saving is taken care off automatically and you do not need to load manually. However, if you for some reason reimplement it and also are using KConfigXT, you must call this function, otherwise the saving of KConfigXT options will not work. Call it at the very end of your reimplementation, to avoid changed() signals getting emitted when you modify widgets.

Reimplemented in KCModuleContainer, and KSettings::PluginPage.

Definition at line 225 of file kcmodule.cpp.

◆ setAboutData()

void KCModule::setAboutData ( const KAboutData * about )

This sets the KAboutData returned by aboutData() The about data is now owned by KCModule.

Definition at line 292 of file kcmodule.cpp.

◆ setButtons()

void KCModule::setButtons ( Buttons btn )

protected

Sets the buttons to display.

Help: shows a "Help" button.

Default: shows a "Use Defaults" button.

Apply: in kcontrol this will show an "Apply" and "Reset" button, in kcmshell this will show an "Ok", "Apply", "Reset" and "Cancel" button.

If Apply is not specified, kcmshell will show a "Close" button.

See also: KCModule::buttons

Definition at line 101 of file kcmodule.cpp.

◆ setDefaultsIndicatorsVisible

void KCModule::setDefaultsIndicatorsVisible ( bool show )

slot

Show an indicator when settings value differ from default.

Since: 5.73

Definition at line 153 of file kcmodule.cpp.

◆ setExportText()

void KCModule::setExportText ( const QString & text )

Sets the export QString value, used for exporting data.

Deprecated:: since 5.0, obsolete feature

Definition at line 349 of file kcmodule.cpp.

◆ setNeedsAuthorization()

void KCModule::setNeedsAuthorization ( bool needsAuth )

Set if the module's save() method requires authorization to be executed.

The module can set this property to true if it requires authorization. It will still have to execute the action itself using the KAuth library, so this method is not technically needed to perform the action, but using this and/or the setAuthAction() method will ensure that hosting applications like System Settings or kcmshell behave correctly.

Called with true, this method will set the action to "org.kde.kcontrol.name.save" where "name" is aboutData()->appName() return value. This default action won't be set if the aboutData() object is not valid.

Note that called with false, this method will reset the action name set with setAuthAction().

Parameters

needsAuth Tells if the module's save() method requires authorization to be executed.

Definition at line 132 of file kcmodule.cpp.

◆ setQuickHelp()

void KCModule::setQuickHelp ( const QString & help )

protected

Sets the quick help.

Definition at line 355 of file kcmodule.cpp.

◆ setRootOnlyMessage()

void KCModule::setRootOnlyMessage ( const QString & message )

protected

Sets the RootOnly message.

This message will be shown at the top of the module if useRootOnlyMessage is set. If no message is set, a default one will be used.

See also: KCModule::rootOnlyMessage

Definition at line 300 of file kcmodule.cpp.

◆ setUseRootOnlyMessage()

void KCModule::setUseRootOnlyMessage ( bool on )

protected

Change whether or not the RootOnly message should be shown.

Following the value of on, the RootOnly message will be shown or not.

See also: KCModule::useRootOnlyMessage

Definition at line 311 of file kcmodule.cpp.

◆ unmanagedWidgetChangeState()

void KCModule::unmanagedWidgetChangeState ( bool changed )

protected

Call this method when your manually managed widgets change state between changed and not changed.

Definition at line 272 of file kcmodule.cpp.

◆ unmanagedWidgetDefaultState()

void KCModule::unmanagedWidgetDefaultState ( bool defaulted )

protected

Call this method when your manually managed widgets change state between defaulted and not defaulted.

Since: 5.65

Definition at line 278 of file kcmodule.cpp.

◆ useRootOnlyMessage()

bool KCModule::useRootOnlyMessage ( ) const

Tell if KControl should show a RootOnly message when run as a normal user.

In some cases, the module don't want a RootOnly message to appear (for example if it has already one). This function tells KControl if a RootOnly message should be shown

See also: KCModule::setUseRootOnlyMessage

Definition at line 317 of file kcmodule.cpp.

◆ widgetChanged

void KCModule::widgetChanged ( )

protectedslot

A managed widget was changed, the widget settings and the current settings are compared and a corresponding changed() signal is emitted.
