<p><a class="el" href="classsigc_1_1signal.html" title="Convenience wrapper for the numbered sigc::signal# templates.">signal</a> can be used to <a class="el" href="classsigc_1_1signal7.html#adc55ac9b0f935fd87a67904022e03cb2" title="Add a slot to the list of slots.">connect()</a> slots that are invoked during subsequent calls to <a class="el" href="classsigc_1_1signal7.html#a5ee8eaa67f05f84ee185841142a34fb0" title="Triggers the emission of the signal.">emit()</a>. Any functor or <a class="el" href="classsigc_1_1slot.html" title="Convenience wrapper for the numbered sigc::slot# templates.">slot</a> can be passed into <a class="el" href="classsigc_1_1signal7.html#adc55ac9b0f935fd87a67904022e03cb2" title="Add a slot to the list of slots.">connect()</a>. It is converted into a <a class="el" href="classsigc_1_1slot.html" title="Convenience wrapper for the numbered sigc::slot# templates.">slot</a> implicitly.</p>
<p>If you want to connect one <a class="el" href="classsigc_1_1signal.html" title="Convenience wrapper for the numbered sigc::signal# templates.">signal</a> to another, use <a class="el" href="classsigc_1_1signal7.html#a0948c25035b18b01efa60d08b26f6d51" title="Creates a functor that calls emit() on this signal.">make_slot()</a> to retrieve a functor that emits the <a class="el" href="classsigc_1_1signal.html" title="Convenience wrapper for the numbered sigc::signal# templates.">signal</a> when invoked.</p>
<p>Be careful if you directly pass one <a class="el" href="classsigc_1_1signal.html" title="Convenience wrapper for the numbered sigc::signal# templates.">signal</a> into the <a class="el" href="classsigc_1_1signal7.html#adc55ac9b0f935fd87a67904022e03cb2" title="Add a slot to the list of slots.">connect()</a> method of another: a shallow copy of the <a class="el" href="classsigc_1_1signal.html" title="Convenience wrapper for the numbered sigc::signal# templates.">signal</a> is made and the signal's slots are not disconnected until both the <a class="el" href="classsigc_1_1signal.html" title="Convenience wrapper for the numbered sigc::signal# templates.">signal</a> and its clone are destroyed which is probably not what you want!</p>
<p>An STL-style list interface for the signal's list of slots can be retrieved with <a class="el" href="classsigc_1_1signal7.html#a68153d9079b4881352113079cd6216f7" title="Creates an STL-style interface for the signal's list of slots.">slots()</a>. This interface supports iteration, insertion and removal of slots.</p>

<p>To specify an accumulator type the nested class <a class="el" href="classsigc_1_1signal_1_1accumulated.html" title="Convenience wrapper for the numbered sigc::signal# templates.">signal::accumulated</a> can be used.</p>
