Constructor & Destructor Documentation
KConfig::KConfig | ( | const QString & | fileName = QString::null , |
|
bool | bReadOnly = false , |
|||
bool | bUseKDEGlobals = true , |
|||
const char * | resType = "config" | |||
) |
Constructs a KConfig object.
- Parameters:
-
fileName A file to parse in addition to the system-wide file(s). If it is not provided, only global KDE configuration data will be read (depending on the value of bUseKDEGlobals
).bReadOnly Set the config object's read-only status. Note that the object will automatically become read-only if either the user does not have write permission to fileName
or if no file was specified.bUseKDEGlobals Toggle reading the global KDE configuration file. resType the place to look in (config, data, etc) See KStandardDirs.

KConfig::~KConfig | ( | ) | [virtual] |
Destructs the KConfig object.
Writes back any dirty configuration entries, and destroys dynamically created objects.
Definition at line 87 of file kconfig.cpp.
Member Function Documentation
void KConfig::rollback | ( | bool | bDeep = true |
) | [virtual] |
Clears all entries out of the dirtyEntryMap
, so the values will not be written to disk on a later call to sync().
- Parameters:
-
bDeep If true, the dirty map is actually emptied. otherwise, the config object's global dirty flag is set to false, but the dirty entries remain in the dirty entry map.
- See also:
- KConfigBase::rollback
Reimplemented from KConfigBase.
Definition at line 94 of file kconfig.cpp.
QStringList KConfig::groupList | ( | ) | const [virtual] |
Returns a list of groups that are known.
- Returns:
- a list of of groups
Implements KConfigBase.
Definition at line 107 of file kconfig.cpp.
Returns a map (tree) of entries for all entries in a particular group.
Only the actual entry string is returned, none of the other internal data should be included.
- Parameters:
-
pGroup A group to get keys from.
- Returns:
- A map of entries in the group specified, indexed by key. The returned map may be empty if the group is not found.
Implements KConfigBase.
Definition at line 141 of file kconfig.cpp.
void KConfig::reparseConfiguration | ( | ) | [virtual] |
Clears all internal data structures and then reread configuration information from disk.
Implements KConfigBase.
Definition at line 161 of file kconfig.cpp.
void KConfig::setFileWriteMode | ( | int | mode | ) |
Set the file mode for newly created files.
- Parameters:
-
mode the mode for new files as described in chmod(2)
- See also:
- man:chmod(2) for a description of
mode
Definition at line 275 of file kconfig.cpp.
void KConfig::setForceGlobal | ( | bool | force | ) | [inline] |
Forces all following write-operations being performed on kdeglobals, independent of the bGlobal flag in writeEntry().
- Parameters:
-
force true to force writing in kdeglobals
- See also:
- forceGlobal
bool KConfig::forceGlobal | ( | ) | const [inline] |
Returns true if all entries are being written into kdeglobals.
- Returns:
- true if all entries are being written into kdeglobals
- See also:
- setForceGlobal
Checks whether the config file contains the update id
as contained in updateFile
.
If not, it runs kconf_update to update the config 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
- Since:
- 3.1
Definition at line 287 of file kconfig.cpp.
Copies all entries from this config object to a new config object that will save itself to file
.
Actual saving to file
happens when the returned object is destructed or when sync() is called upon it.
- Parameters:
-
file the new config object will save itself to. config optional config object to reuse
- Since:
- 3.2
Definition at line 303 of file kconfig.cpp.
KLockFile::Ptr KConfig::lockFile | ( | bool | bGlobal = false |
) |
Returns a lock file object for the configuration file or 0 if the backend does not support locking.
- Parameters:
-
bGlobal if true, return the lock file for the global config file
- Since:
- 3.3
Definition at line 280 of file kconfig.cpp.
bool KConfig::internalHasGroup | ( | const QCString & | group | ) | const [protected, virtual] |
Returns true if the specified group is known.
- Parameters:
-
group The group to search for.
- Returns:
- true if the group exists.
Implements KConfigBase.
Definition at line 254 of file kconfig.cpp.
KEntryMap KConfig::internalEntryMap | ( | const QString & | pGroup | ) | const [protected, virtual] |
Returns a map (tree) of the entries in the specified group.
This may or may not return all entries that belong to the config object. The only guarantee that you are given is that any entries that are dirty (i.e. modified and not yet written back to the disk) will be contained in the map. Some derivative classes may choose to return everything.
Do not use this function, the implementation / return type are subject to change.
- Parameters:
-
pGroup The group to provide a KEntryMap for.
- Returns:
- The map of the entries in the group.
Implements KConfigBase.
Definition at line 178 of file kconfig.cpp.
virtual KEntryMap KConfig::internalEntryMap | ( | ) | const [inline, protected, virtual] |
Returns a map (tree) of the entries in the tree.
Do not use this function, the implementation / return type are subject to change.
- Returns:
- A map of the entries in the tree.
Implements KConfigBase.
void KConfig::putData | ( | const KEntryKey & | _key, | |
const KEntry & | _data, | |||
bool | _checkGroup = true | |||
) | [protected, virtual] |
Inserts a (key, value) pair into the internal storage mechanism of the configuration object.
- Parameters:
-
_key The key to insert. It contains information both on the group of the key and the key itself. If the key already exists, the old value will be replaced. _data the KEntry that is to be stored. _checkGroup When false, assume that the group already exists.
Implements KConfigBase.
Definition at line 202 of file kconfig.cpp.
Looks up an entry in the config object's internal structure.
- Parameters:
-
_key The key to look up It contains information both on the group of the key and the entry's key itself.
- Returns:
- the KEntry value (data) found for the key. KEntry.aValue will be the null string if nothing was located.
Implements KConfigBase.
