<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. QFinalState is part of <a href="statemachine-api.html">The State Machine Framework</a>.</p>
<p>To use a final state, you create a QFinalState object and add a transition to it from another state. Example:</p>
<pre> QPushButton button;
QStateMachine machine;
QState *s1 = new QState();
QFinalState *s2 = new QFinalState();
s1->addTransition(&button, SIGNAL(clicked()), s2);
machine.addState(s1);
machine.addState(s2);
QObject.connect(&machine, SIGNAL(finished()), QApplication.instance(), SLOT(quit()));
machine.setInitialState(s1);
machine.start();</pre>
