DESCRIPTION
The QSignalMapper class bundles signals from identifiable
senders.
Collects a set of parameterless signals, re-emitting them
with an integer or string parameters corresponding to the
object which sent the signal.
Examples: i18n/main.cpp
MEMBER FUNCTION DOCUMENTATIONQSignalMapper::QSignalMapper ( QObject * parent, const char *
name=0 )
Constructs a QSignalMapper. Like all QObjects, it will be
deleted when the parent is deleted.
QSignalMapper::~QSignalMapper ()
Destructs the QSignalMapper.
void QSignalMapper::map () [slot]
This slot emits signals based on which object sends
signals to it.
void QSignalMapper::mapped ( const QString & ) [signal]
This signal is emitted when map() is signalled from an
object which has a string mapping set.
See also setMapping(QString).

QSignalMapper(3qt)QSignalMapper(3qt)void QSignalMapper::mapped ( int ) [signal]
This signal is emitted when map() is signalled from an
object which has an integer mapping set.
See also setMapping(int).
void QSignalMapper::removeMappings ( const QObject * sender )
Removes all mappings for sender. This is done
automatically when mapped objects are destroyed.
void QSignalMapper::setMapping ( const QObject * sender, const
QString & identifier ) [virtual]
Adds a mapping such that when map() is signalled from the
given sender, the signal mapper(identifier) is emitted.
There may be at most one string identifier for each
object, and it may not be null.
Examples: i18n/main.cpp
void QSignalMapper::setMapping ( const QObject * sender, int
identifier ) [virtual]
Adds a mapping such that when map() is signalled from the
given sender, the signal mapped(identifier) is emitted.
There may be at most one integer identifier for each
object.
