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.

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

Definition at line 110 of file kcmodule.h.

Constructor & Destructor Documentation

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

Definition at line 75 of file kcmodule.cpp.

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 81 of file kcmodule.cpp.

KCModule::~KCModule ( )

override

Destroys the module.

Definition at line 185 of file kcmodule.cpp.

Member Function Documentation

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

Definition at line 238 of file kcmodule.cpp.

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 107 of file kcmodule.cpp.

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

Definition at line 116 of file kcmodule.cpp.

KAuth::Action KCModule::authAction ( ) const

Returns the action previously set with setAuthAction().

By default its an invalid action.

Returns: The action that has to be authorized to execute the save() method.

Definition at line 160 of file kcmodule.cpp.

void KCModule::authStatusChanged ( KAuth::Action::AuthStatus status )

protectedslot

The status of the auth action, if one, has changed.

Definition at line 165 of file kcmodule.cpp.

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 97 of file kcmodule.cpp.

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.

void KCModule::changed ( )

protectedslot

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

Definition at line 273 of file kcmodule.cpp.

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

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

Definition at line 304 of file kcmodule.cpp.

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 209 of file kcmodule.cpp.

QString KCModule::exportText ( ) const

Returns the value set by setExportText();.

Deprecated:: since 5.0, obsolete feature

Definition at line 283 of file kcmodule.cpp.

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 193 of file kcmodule.cpp.

bool KCModule::managedWidgetChangeState ( ) const

protected

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

Definition at line 221 of file kcmodule.cpp.

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 141 of file kcmodule.cpp.

QString KCModule::quickHelp ( ) const

virtual

Return a quick-help text.

This method is called when the module is docked. 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 299 of file kcmodule.cpp.

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.

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 257 of file kcmodule.cpp.

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

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 201 of file kcmodule.cpp.

void KCModule::setAboutData ( const KAboutData * about )

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

Definition at line 243 of file kcmodule.cpp.

void KCModule::setAuthAction ( const KAuth::Action & action )

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

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 method will ensure that hosting applications like System Settings or kcmshell behave correctly.

Parameters

action the action that will be used by this KCModule

Definition at line 147 of file kcmodule.cpp.

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" and "Cancel" button.

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

See also: KCModule::buttons

Definition at line 102 of file kcmodule.cpp.

void KCModule::setExportText ( const QString & text )

Sets the export QString value, used for exporting data.

Deprecated:: since 5.0, obsolete feature

Definition at line 288 of file kcmodule.cpp.

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.
