<hr><a name="details"></a><h2>Detailed Description</h2>
The QSignalMapper class bundles signals from identifiable senders.
<p> 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.
<p>See also <a href="io.html">Input/Output and Networking</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QSignalMapper"></a>QSignalMapper::QSignalMapper ( <a href="qobject.html">QObject</a> * parent, const char * name = 0 )
</h3>
Constructs a QSignalMapper with parent <em>parent</em> and name <em>name</em>.
Like all QObjects, it will be deleted when the parent is deleted.
<h3 class=fn><a name="~QSignalMapper"></a>QSignalMapper::~QSignalMapper ()
</h3>
Destroys the QSignalMapper.
<h3 class=fn>void <a name="map"></a>QSignalMapper::map ()<tt> [slot]</tt>
</h3>
This slot emits signals based on which object sends signals
to it.
<p>Examples: <a href="i18n-example.html#x1376">i18n/main.cpp</a> and <a href="themes-example.html#x351">themes/themes.cpp</a>.
<h3 class=fn>void <a name="mapped"></a>QSignalMapper::mapped ( int )<tt> [signal]</tt>
</h3>
<p> This signal is emitted when <a href="#map">map</a>() is signaled from an object that
has an integer mapping set.
<p> <p>See also <a href="#setMapping">setMapping</a>().
<p>Examples: <a href="i18n-example.html#x1377">i18n/main.cpp</a> and <a href="themes-example.html#x352">themes/themes.cpp</a>.
<h3 class=fn>void <a name="mapped-2"></a>QSignalMapper::mapped ( const <a href="qstring.html">QString</a> & )<tt> [signal]</tt>
</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> This signal is emitted when <a href="#map">map</a>() is signaled from an object that
has a string mapping set.
<p> <p>See also <a href="#setMapping">setMapping</a>().
<h3 class=fn>void <a name="removeMappings"></a>QSignalMapper::removeMappings ( const <a href="qobject.html">QObject</a> * sender )
</h3>
Removes all mappings for <em>sender</em>. This is done automatically
when mapped objects are destroyed.
<h3 class=fn>void <a name="setMapping"></a>QSignalMapper::setMapping ( const <a href="qobject.html">QObject</a> * sender, int identifier )<tt> [virtual]</tt>
</h3>
Adds a mapping so that when <a href="#map">map</a>() is signaled from the given
<em>sender</em>, the signal <a href="#mapped">mapped</a>(<em>identifier</em>) is emitted.
<p> There may be at most one integer identifier for each object.
<p>Examples: <a href="i18n-example.html#x1378">i18n/main.cpp</a> and <a href="themes-example.html#x353">themes/themes.cpp</a>.
<h3 class=fn>void <a name="setMapping-2"></a>QSignalMapper::setMapping ( const <a href="qobject.html">QObject</a> * sender, const <a href="qstring.html">QString</a> & identifier )<tt> [virtual]</tt>
</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Adds a mapping so that when <a href="#map">map</a>() is signaled from the given
<em>sender</em>, the signal mapper(<em>identifier</em>) is emitted.
<p> There may be at most one string identifier for each object, and
it may not be null.
