List of all members.


Detailed Description

A class for one specific group in a KConfig object.

If you want to access the top-level entries of a KConfig object, which are not associated with any group, use an empty group name. A KConfigGroup can be read-only if it is constructed from a const config object or from another read-only group.

Constructor & Destructor Documentation

KConfigGroup::KConfigGroup (  ) 

Constructs a null group.

A null group is invalid.

See also:
isValid

Definition at line 511 of file kconfiggroup.cpp.

KConfigGroup::KConfigGroup ( KConfigBase *  master,
const QString &  group 
)

Construct a config group corresponding to group in master.

This allows to create subgroups, by passing an existing group as master.

group is the group name encoded in UTF-8.

Definition at line 537 of file kconfiggroup.cpp.

KConfigGroup::KConfigGroup ( KConfigBase *  master,
const char *  group 
)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Definition at line 542 of file kconfiggroup.cpp.

KConfigGroup::KConfigGroup ( const KConfigBase *  master,
const QString &  group 
)

Construct a read-only config group.

A read-only group will silently ignore any attempts to write to it.

This allows to create subgroups, by passing an existing group as master.

Definition at line 547 of file kconfiggroup.cpp.

KConfigGroup::KConfigGroup ( const KConfigBase *  master,
const char *  group 
)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Definition at line 552 of file kconfiggroup.cpp.

KConfigGroup::KConfigGroup ( const KSharedConfigPtr &  master,
const QString &  group 
)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Check whether the containing KConfig object acutally contains a group with this name.

Definition at line 639 of file kconfiggroup.cpp.

void KConfigGroup::sync (  )  [virtual]

Reimplemented from superclass.

Implements KConfigBase.

Definition at line 610 of file kconfiggroup.cpp.

template<typename T>
T KConfigGroup::readEntry ( const QString &  key,
const T &  aDefault 
) const [inline]

Reads the value of an entry specified by pKey in the current group.

This template method makes it possible to write QString foo = readEntry("...", QString("default")); and the same with all other types supported by QVariant. The return type of the method is simply the same as the type of the default value.

Note:
readEntry("...", Qt::white) cannot compile because Qt::white is an enum. You must turn it into readEntry("...", QColor(Qt::white)).

Only the following QVariant types are allowed : String, StringList, List, Font, Point, Rect, Size, Color, Int, UInt, Bool, Double, LongLong, ULongLong, DateTime and Date.

Parameters:
pKey The key to search for.
aDefault A default value returned if the key was not found.
Returns:
The value for this key, or aDefault.

Definition at line 186 of file kconfiggroup.h.

template<typename T>
T KConfigGroup::readEntry ( const char *  key,
const T &  aDefault 
) const [inline]

Definition at line 192 of file kconfiggroup.h.

QVariant KConfigGroup::readEntry ( const QString &  key,
const QVariant &  aDefault 
) const

Reads the value of an entry specified by key in the current group.

Parameters:
key The key to search for.
aDefault A default value returned if the key was not found.
Returns:
The value for this key.
Note:
The return value will always have the same QVariant::Type as aDefault. This implies that the only possible return value for aDefault == QVariant() is QVariant().

Definition at line 767 of file kconfiggroup.cpp.

QVariant KConfigGroup::readEntry ( const char *  key,
const QVariant &  aDefault 
) const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

key The key to search for.
aDefault A default value returned if the key was not found.
Returns:
The value for this key. Can be QString() if aDefault is null.

Definition at line 713 of file kconfiggroup.cpp.

) const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Warning:
This function doesn't convert the items returned to any type. It's actually a list of QVariant::String's. If you want the items converted to a specific type use readEntry(const char*, const QList<T>&) const
