Detailed Description

The central class of the KDE configuration data system.

Quickstart:

Get the default application config object via KGlobal::config().

Load a specific configuration file:

KConfig config( "/etc/kderc", KConfig::SimpleConfig );

Load the configuration of a specific component (taking into account possible custom directories in KStandardDirs):

KConfig config( componentData(), "pluginrc" );

In general it is recommended to use KSharedConfig instead of creating multiple instances of KConfig to avoid the overhead of separate objects or concerns about synchronizing writes to disk even if the configuration object is updated from multiple code paths. KSharedConfig provides a set of open methods as counterparts for the KConfig constructors.

See also: KSharedConfig, KConfigGroup, the techbase HOWTO on KConfig.

Member Enumeration Documentation

enum KConfig::OpenFlag

Determines how the system-wide and user's global settings will affect the reading of the configuration.

If CascadeConfig is selected, system-wide configuration sources are used to provide defaults for the settings accessed through this object, or possibly to override those settings in certain cases.

IncludeGlobals does the same, but with the global settings sources.

Note that the main configuration source overrides the cascaded sources, which override those provided to addConfigSources(), which override the global sources. The exception is that if a key or group is marked as being immutable, it will not be overridden.

Note that all values other than IncludeGlobals and CascadeConfig are convenience definitions for the basic mode. Do not combine them with anything.

Enumerator
IncludeGlobals	Blend kdeglobals into the config object.
CascadeConfig	Cascade to system-wide config files.
SimpleConfig	Just a single config file.
NoCascade	Include user's globals, but omit system settings.
NoGlobals	Cascade to system settings, but omit user's globals.
FullConfig	Fully-fledged config, including globals and cascading to system settings.

Constructor & Destructor Documentation

KConfig::KConfig	(	const QString &	file = `QString()`,
		OpenFlags	mode = `FullConfig`,
		const char *	resourceType = `"config"`
	)

explicit

Creates a KConfig object to manipulate a configuration file for the current application.

If an absolute path is specified for file, that file will be used as the store for the configuration settings. If a non-absolute path is provided, the file will be looked for in the standard directory specified by resourceType. If no path is provided, a default configuration file will be used based on the name of the main application component.

mode determines whether the user or global settings will be allowed to influence the values returned by this object. See OpenFlags for more details.

Note: You probably want to use KSharedConfig::openConfig instead.

Parameters

file	the name of the file. If an empty string is passed in and SimpleConfig is passed in for the OpenFlags, then an in-memory KConfig object is created which will not write out to file nor which requires any file in the filesystem at all.
mode	how global settings should affect the configuration options exposed by this KConfig object
resourceType	The standard directory to look for the configuration file in (see KStandardDirs)

See also: KSharedConfig::openConfig(const QString&, OpenFlags, const char*)

Definition at line 211 of file kconfig.cpp.

KConfig::KConfig	(	const KComponentData &	componentData,
		const QString &	file = `QString()`,
		OpenFlags	mode = `FullConfig`,
		const char *	resourceType = `"config"`
	)

explicit

Creates a KConfig object to manipulate the configuration for a specific component.

If an absolute path is specified for file, that file will be used as the store for the configuration settings. If a non-absolute path is provided, the file will be looked for in the standard directory specified by resourceType. If no path is provided, a default configuration file will be used based on the component's name.

mode determines whether the user or global settings will be allowed to influence the values returned by this object. See KConfig::OpenFlags for more details.

Note: You probably want to use KSharedConfig::openConfig instead.

Parameters

componentData	the component that you wish to load a configuration file for
file	overrides the configuration file name if not empty; if it is empty and SimpleConfig is passed in for the OpenFlags, then an in-memory KConfig object is created which will not write out to file nor which requires any file in the filesystem at all.
mode	how global settings should affect the configuration options exposed by this KConfig object. See OpenFlags
resourceType	The standard directory to look for the configuration file in

See also: KSharedConfig::openConfig(const KComponentData&, const QString&, OpenFlags, const char*)

Definition at line 221 of file kconfig.cpp.

KConfig::KConfig	(	const QString &	file,
		const QString &	backend,
		const char *	resourceType = `"config"`
	)

Creates a KConfig object using the specified backend. If the backend can not be found or loaded, then the standard configuration parser is used as a fallback.

Parameters

file	the file to be parsed
backend	the backend to load
resourceType	where to look for the file if an absolute path is not provided

Member Function Documentation

KConfig::AccessMode KConfig::accessMode ( ) const

virtual

configuration object state

Reimplemented from superclass.

Implements KConfigBase.

Definition at line 672 of file kconfig.cpp.

void KConfig::addConfigSources ( const QStringList & sources )

extra config files

Adds the list of configuration sources to the merge stack.

Currently only files are accepted as configuration sources.

The first entry in sources is treated as the most general and will be overridden by the second entry. The settings in the final entry in sources will override all the other sources provided in the list.

The settings in sources will also be overridden by the sources provided by any previous calls to addConfigSources().

The settings in the global configuration sources will be overridden by the sources provided to this method (

See also: IncludeGlobals). All the sources provided to any call to this method will be overridden by any files that cascade from the source provided to the constructor (; CascadeConfig), which will in turn be overridden by the source provided to the constructor (either explicitly or implicity via a KComponentData).

Note that only the most specific file, ie: the file provided to the constructor, will be written to by this object.

The state is automatically updated by this method, so there is no need to call reparseConfiguration().

Parameters

sources A list of extra config sources.

Definition at line 678 of file kconfig.cpp.

void KConfig::checkUpdate	(	const QString &	id,
		const QString &	updateFile
	)

Ensures that the configuration file contains a certain update.

If the configuration file does not contain the update id as contained in updateFile, kconf_update is run to update the configuration file.

If you install config update files with critical fixes you may wish to use this method to verify that a critical update has indeed been performed to catch the case where a user restores an old config file from backup that has not been updated yet.

Parameters

id	the update to check
updateFile	the file containing the update

Definition at line 475 of file kconfig.cpp.

const KComponentData & KConfig::componentData ( ) const

Returns the component data this configuration is for.

Definition at line 255 of file kconfig.cpp.

KConfig * KConfig::copyTo	(	const QString &	file,
		KConfig *	config = `0`
	)		const

Copies all entries from this config object to a new config object that will save itself to file.

The configuration will not actually be saved to file until the returned object is destroyed, or sync() is called on it.

Do not forget to delete the returned KConfig object if config was 0.

Parameters

file	the new config object will save itself to
config	if not 0, copy to the given KConfig object rather than creating a new one

Returns: config if it was set, otherwise a new KConfig object

Definition at line 486 of file kconfig.cpp.

void KConfig::deleteGroupImpl	(	const QByteArray &	group,
		WriteConfigFlags	flags = `Normal`
	)

protectedvirtual

Implements KConfigBase.

Definition at line 778 of file kconfig.cpp.

QMap< QString, QString > KConfig::entryMap ( const QString & aGroup = QString() ) const

Returns a map (tree) of entries in a particular group.

The entries are all returned as strings.

Parameters

aGroup The group to get entries from.

Returns: A map of entries in the group specified, indexed by key. The returned map may be empty if the group is empty, or not found.

bool KConfig::isConfigWritable ( bool warnUser )

Whether the configuration can be written to.

If warnUser is true and the configuration cannot be written to (ie: this method returns false), a warning message box will be shown to the user telling them to contact their system administrator to get the problem fixed.

The most likely cause for this method returning false is that the user does not have write permission for the configuration file.

Parameters

warnUser whether to show a warning message to the user if the configuration cannot be written to

Returns: true if the configuration can be written to, false if the configuration cannot be written to

Definition at line 796 of file kconfig.cpp.

bool KConfig::isDirty ( ) const

Returns true if sync has any changes to write out.

Since: 4.12

Definition at line 721 of file kconfig.cpp.

void KConfig::reparseConfiguration ( )

Updates the state of this object to match the persistent storage.

Definition at line 557 of file kconfig.cpp.

void KConfig::setForceGlobal ( bool force )

global

Deprecated:

Forces all following write-operations to be performed on kdeglobals, independent of the Global flag in writeEntry().

Parameters

force true to force writing to kdeglobals

See also: forceGlobal

Definition at line 740 of file kconfig.cpp.

bool KConfig::setLocale ( const QString & aLocale )

Sets the locale to aLocale.

The global locale is used by default.

Note: If set to the empty string, no locale will be matched. This effectively disables reading translated entries.

Returns: true if locale was changed, false if the call had no effect (eg: aLocale was already the current locale for this object)

Definition at line 705 of file kconfig.cpp.

void KConfig::setReadDefaults ( bool b )

defaults

When set, all readEntry calls return the system-wide (default) values instead of the user's settings.

This is off by default.

Parameters

b	whether to read the system-wide defaults instead of the user's settings
