\class QFinalState
\inmodule QtStateMachine
\brief The QFinalState class provides a final state.
\since 4.6
\ingroup statemachine
A final state is used to communicate that (part of) a QStateMachine has
finished its work. When a final top-level state is entered, the state
machine's \l{QStateMachine::finished()}{finished}() signal is emitted. In
general, when a final substate (a child of a QState) is entered, the parent
state's \l{QState::finished()}{finished}() signal is emitted. QFinalState
is part of \l{Qt State Machine Overview}{Qt State Machine Framework}.
To use a final state, you create a QFinalState object and add a transition
to it from another state. Example:
\code
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();
\endcode
\sa QState::finished()
