Abstract base class for KDE configuration entries.
This class forms the base for all KDE configuration. It is an abstract base class, meaning that you cannot directly instantiate objects of this class. Either use KConfig (for usual KDE configuration) or KSimpleConfig (for special needs as in ksamba), or even KSharedConfig (stores values in shared memory).
All configuration entries are key, value pairs. Each entry also belongs to a specific group of related entries. All configuration entries that do not explicitly specify which group they are in are in a special group called the default group.
If there is a $ character in an entry, KConfigBase tries to expand environment variable and uses its value instead of its name. You can avoid this feature by having two consecutive $ characters in your config file which get expanded to one.

when writing it back.

| void writeEntry ( const char *pKey, const QSize& rValue,
bool bPersistent = true, bool bGlobal = false,
bool bNLS = false )
| writeEntry |
| void setDollarExpansion ( bool _bExpand = true )
| setDollarExpansion |
Turns on or off "dollar expansion" (see KConfigBase introduction) when reading config entries. Dollar sign expansion is initially OFF.
Parameters:
| _bExpand | Tf true, dollar expansion is turned on. |
| bool isDollarExpansion ()
| isDollarExpansion |
[const]
Returns whether dollar expansion is on or off. It is initially OFF.
Returns: true if dollar expansion is on.
| void rollback ( bool bDeep = true )
| rollback |
[virtual]
Mark the config object as "clean," i.e. don't write dirty entries
at destruction time. If bDeep is false, only the global dirty
flag of the KConfig object gets cleared. If you then call
writeEntry() again, the global dirty flag is set again and all
dirty entries will be written at a subsequent sync() call.
Classes that derive from KConfigObject should override this method and implement storage-specific behaviour, as well as calling the KConfigBase::rollback() explicitly in the initializer.
Parameters:
| bDeep | If true, the dirty flags of all entries are cleared,
as well as the global dirty flag.
|
| void sync ()
| sync |
[virtual]
Flush all changes that currently reside only in memory back to disk / permanent storage. Dirty configuration entries are written to the most specific file available.
Asks the back end to flush out all pending writes, and then calls
rollback(). No changes are made if the object has readOnly
status.
You should call this from your destructor in derivative classes.
See also: rollback(), isReadOnly()
| bool isDirty ()
| isDirty |
[const]
Returns: true if the config file has any dirty (modified) entries.
| void setReadOnly (bool _ro)
| setReadOnly |
[virtual]
Set the config object's read-only status.
Parameters:
| _ro | If true, the config object will not write out any
changes to disk even if it is destroyed or sync() is called.
|
| bool isReadOnly ()
| isReadOnly |
[const]
Queries the read-only status of the config object.
Returns: The read-only status.
| bool hasKey ( const QString& pKey )
| hasKey |
[const pure virtual]
Check whether the key has an entry in the currently active group. Use this to determine whether a key is not specified for the current group (hasKey() returns false). Keys with null data are considered nonexistent.
Parameters:
| pKey | The key to search for. |
Returns: If true, the key is available.
| QMap<QString, QString> entryMap (const QString &pGroup)
| entryMap |
[const pure virtual]
Return 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.

| void reparseConfiguration ()
| reparseConfiguration |
[pure virtual]
Reparses all configuration files. This is useful for programs that use standalone graphical configuration tools. The base method implemented here only clears the group list and then appends the default group.
Derivative classes should clear any internal data structures and then simply call parseConfigFiles() when implementing this method.
See also: parseConfigFiles()
| enum ConfigState { NoAccess, ReadOnly, ReadWrite } | ConfigState |
Possible return values for getConfigState().
See also: getConfigState()
| ConfigState getConfigState ()
| getConfigState |
[const]
Retrieve the state of the app-config object.
Possible return values are NoAccess (the application-specific config file could not be opened neither read-write nor read-only), ReadOnly (the application-specific config file is opened read-only, but not read-write) and ReadWrite (the application-specific config file is opened read-write).
See also: ConfigState()
| void setLocale ()
| setLocale |
[protected]
Read the locale and put in the configuration data struct. Note that this should be done in the constructor, but this is not possible due to some mutual dependencies in KApplication::init()
| void setDirty (bool _bDirty = true)
| setDirty |
[protected virtual]
Sets the global dirty flag of the config object
Parameters:
| _bDirty | How to mark the object's dirty status |
| void parseConfigFiles ()
| parseConfigFiles |
[protected virtual]
Parse all configuration files for a configuration object.
The actual parsing is done by the associated KConfigBackEnd.
| KEntryMap internalEntryMap ( const QString& pGroup )
| internalEntryMap |
[protected const pure virtual]
Returns an 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.
| KEntryMap internalEntryMap ()
| internalEntryMap |
[protected const pure virtual]
Returns an 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.
| void putData (const KEntryKey &_key, const KEntry &_data)
| putData |
[protected pure virtual]
Insert a key,value pair into the internal storage mechanism of the configuration object. Classes that derive from KConfigBase will need to implement this method in a storage-specific manner.
Do not use this function, the implementation / return type are subject to change.
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. |
| KEntry lookupData (const KEntryKey &_key)
| lookupData |
[protected const pure virtual]
Look up an entry in the config object's internal structure. Classes that derive from KConfigBase will need to implement this method in a storage-specific manner.
Do not use this function, the implementation and return type are subject to change.
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.
