<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qfinalstate.html">QFinalState</a> class provides a final state.</p>
<p>A final state is used to communicate that (part of) a <a href="qstatemachine.html">QStateMachine</a> has finished its work. When a final top-level state is entered, the state machine's <a href="qstate.html#finished">finished</a>() signal is emitted. In general, when a final substate (a child of a <a href="qstate.html">QState</a>) is entered, the parent state's <a href="qstate.html#finished">finished</a>() signal is emitted. <a href="qfinalstate.html">QFinalState</a> is part of <a href="statemachine-api.html">The State Machine Framework</a>.</p>
<p>To use a final state, you create a <a href="qfinalstate.html">QFinalState</a> object and add a transition to it from another state. Example:</p>
<pre class="cpp">
<span class="type"><a href="../qtwidgets/qpushbutton.html">QPushButton</a></span> button;
<span class="type"><a href="qstatemachine.html">QStateMachine</a></span> machine;
<span class="type"><a href="qstate.html">QState</a></span> <span class="operator">*</span>s1 <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qstate.html">QState</a></span>();
<span class="type"><a href="qfinalstate.html#QFinalState">QFinalState</a></span> <span class="operator">*</span>s2 <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qfinalstate.html#QFinalState">QFinalState</a></span>();
s1<span class="operator">-</span><span class="operator">></span>addTransition(<span class="operator">&</span>button<span class="operator">,</span> SIGNAL(clicked())<span class="operator">,</span> s2);
machine<span class="operator">.</span>addState(s1);
machine<span class="operator">.</span>addState(s2);
<span class="type"><a href="qobject.html#QObject">QObject</a></span><span class="operator">::</span>connect(<span class="operator">&</span>machine<span class="operator">,</span> SIGNAL(finished())<span class="operator">,</span> <span class="type"><a href="../qtwidgets/qapplication.html">QApplication</a></span><span class="operator">::</span>instance()<span class="operator">,</span> SLOT(quit()));
machine<span class="operator">.</span>setInitialState(s1);
machine<span class="operator">.</span>start();
</pre>
