Detailed Description

Abstract base class for KDE configuration file loading/saving. KDE Configuration file loading/saving abstract base class.

This class forms the base for all classes that implement some manner of loading/saving to configuration files. It is an abstract base class, meaning that you cannot directly instantiate objects of this class. As of right now, the only back end available is one to read/write to INI-style files, but in the future, other formats may be available, such as XML or a database.

Constructor & Destructor Documentation

KConfigBackEnd::KConfigBackEnd KConfigBase   _config,
const QString   _fileName,
const char *    _resType,
bool    _useKDEGlobals
 

Constructs a configuration back end.

Parameters:
_config  Specifies the configuration object which values will be passed to as they are read, or from where values to be written to will be obtained from.
_fileName  The name of the file in which config data is stored. All registered configuration directories will be looked in in order of decreasing relevance.
_resType  the resource type of the fileName specified, _if_ it is not an absolute path (otherwise this parameter is ignored).
_useKDEGlobals  If true, the user's system-wide kdeglobals file will be imported into the config object. If false, only the filename specified will be dealt with.

virtual KConfigBackEnd::~KConfigBackEnd   [inline, virtual]
 

Destructs the configuration backend.

Member Function Documentation

virtual bool KConfigBackEnd::parseConfigFiles   [pure virtual]
 

Parses all configuration files for a configuration object.

This method must be reimplemented by the derived classes.

Returns:
Whether or not parsing was successful.

Implemented in KConfigINIBackEnd.

Referenced by KConfigBase::parseConfigFiles().

virtual void KConfigBackEnd::sync bool    bMerge = true [pure virtual]
 

Writes configuration data to file(s).

This method must be reimplemented by the derived classes.

Parameters:
bMerge  Specifies whether the old config file already on disk should be merged in with the data in memory. If true, data is read off the disk and merged. If false, the on-disk file is removed and only in-memory data is written out.

Implemented in KConfigINIBackEnd.

Referenced by KSimpleConfig::sync(), and KConfigBase::sync().

void KConfigBackEnd::changeFileName const QString   _fileName,
const char *    _resType,
bool    _useKDEGlobals
 

Changes the filenames associated with this back end.

You should probably reparse your config info after doing this.

Parameters:
_fileName  the new filename to use
_resType  the resource type of the fileName specified, _if_ it is not an absolute path (otherwise this parameter is ignored).
_useKDEGlobals  specifies whether or not to also parse the global KDE configuration files.
