41 \class QFinalState-
42 \inmodule QtCore-
43-
44 \brief The QFinalState class provides a final state.-
45-
46 \since 4.6-
47 \ingroup statemachine-
48-
49 A final state is used to communicate that (part of) a QStateMachine has-
50 finished its work. When a final top-level state is entered, the state-
51 machine's \l{QStateMachine::finished()}{finished}() signal is emitted. In-
52 general, when a final substate (a child of a QState) is entered, the parent-
53 state's \l{QState::finished()}{finished}() signal is emitted. QFinalState-
54 is part of \l{The State Machine Framework}.-
55-
56 To use a final state, you create a QFinalState object and add a transition-
57 to it from another state. Example:-
58-
59 \code-
60 QPushButton button;-
61-
62 QStateMachine machine;-
63 QState *s1 = new QState();-
64 QFinalState *s2 = new QFinalState();-
65 s1->addTransition(&button, SIGNAL(clicked()), s2);-
66 machine.addState(s1);-
67 machine.addState(s2);-
68-
69 QObject::connect(&machine, SIGNAL(finished()), QApplication::instance(), SLOT(quit()));-
70 machine.setInitialState(s1);-
71 machine.start();-
72 \endcode-
