.SH DESCRIPTION
|
|
The QSignalMapper class bundles signals from identifiable senders.
|
|
.PP
|
|
This class collects a set of parameterless signals, and re-emits them with integer or string parameters corresponding to the object that sent the signal.
|
|
.PP
|
|
See also Input/Output and Networking.
|
|
.SH MEMBER FUNCTION DOCUMENTATION
|
|
.SH "QSignalMapper::QSignalMapper ( QObject * parent, const char * name = 0 )"
|
|
Constructs a QSignalMapper called \fIname\fR, with parent \fIparent\fR. Like all QObjects, it will be deleted when the parent is deleted.
|
|
.SH "QSignalMapper::~QSignalMapper ()"
|
|
Destroys the QSignalMapper.
|
|
.SH "void QSignalMapper::map ()\fC [slot]\fR"
|
|
This slot emits signals based on which object sends signals to it.
|
|
.PP
|
|
Examples:
|
|
.)l i18n/main.cpp and themes/themes.cpp.
|
|
.SH "void QSignalMapper::mapped ( int )\fC [signal]\fR"
|
|
This signal is emitted when map() is signaled from an object that has an integer mapping set.
|
|
.PP
|
|
See also setMapping().
|
|
.PP
|
|
Examples:
|
|
.)l i18n/main.cpp and themes/themes.cpp.
|
|
.SH "void QSignalMapper::mapped ( const QString & )\fC [signal]\fR"
|
|
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
|
|
.PP
|
|
This signal is emitted when map() is signaled from an object that has a string mapping set.
|
|
.PP
|
|
See also setMapping().
|
|
.SH "void QSignalMapper::removeMappings ( const QObject * sender )"
|
|
Removes all mappings for \fIsender\fR. This is done automatically when mapped objects are destroyed.
|
|
.SH "void QSignalMapper::setMapping ( const QObject * sender, int identifier )\fC [virtual]\fR"
|
|
Adds a mapping so that when map() is signaled from the given \fIsender\fR, the signal mapped(\fIidentifier\fR) is emitted.
|
|
.PP
|
|
There may be at most one integer identifier for each object.
|
|
.PP
|
|
Examples:
|
|
.)l i18n/main.cpp and themes/themes.cpp.
|
|
.SH "void QSignalMapper::setMapping ( const QObject * sender, const QString & identifier )\fC [virtual]\fR"
|
|
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
|
|
.PP
|
|
Adds a mapping so that when map() is signaled from the given \fIsender\fR, the signal mapper(\fIidentifier\fR) is emitted.
|
|
.PP
|
|
There may be at most one string identifier for each object, and it
|
|
may not be empty.
