It is converted into a <a class="el" href="classsigc_1_1slot.html" title="Convenience wrapper for the numbered sigc::slot# templates.">slot</a> implicitely.</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_1signal3.html#a025abd721a15f3d6a0d5e1bfe329d796" 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_1signal3.html#a3eae0b3796b2736be847f33a5124aacd" 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_1signal3.html#ab9606b708078956a758b81503f956bee" 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>The following template arguments are used:</p>
<ul>
<li><em>T_return</em> The desired return type for the <a class="el" href="classsigc_1_1signal3.html#a85f1768341d975b5b81418ac774b47d8" title="Triggers the emission of the signal.">emit()</a> function (may be overridden by the accumulator).</li>
<li><em>T_arg1</em> Argument type used in the definition of <a class="el" href="classsigc_1_1signal3.html#a85f1768341d975b5b81418ac774b47d8" title="Triggers the emission of the signal.">emit()</a>.</li>
<li><em>T_arg2</em> Argument type used in the definition of <a class="el" href="classsigc_1_1signal3.html#a85f1768341d975b5b81418ac774b47d8" title="Triggers the emission of the signal.">emit()</a>.</li>
<li><em>T_arg3</em> Argument type used in the definition of <a class="el" href="classsigc_1_1signal3.html#a85f1768341d975b5b81418ac774b47d8" title="Triggers the emission of the signal.">emit()</a>.</li>
<li><em>T_accumulator</em> The accumulator type used for emission. The default <code>nil</code> means that no accumulator should be used, i.e. <a class="el" href="classsigc_1_1signal.html" title="Convenience wrapper for the numbered sigc::signal# templates.">signal</a> emission returns the return value of the last <a class="el" href="classsigc_1_1slot.html" title="Convenience wrapper for the numbered sigc::slot# templates.">slot</a> invoked.</li>
</ul>
<p>You should use the more convenient unnumbered <a class="el" href="classsigc_1_1signal.html" title="Convenience wrapper for the numbered sigc::signal# templates.">sigc::signal</a> template. </p>
