Detailed Description▲
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 finished() signal is emitted. In general, when a final substate (a child of a QState) is entered, the parent state's finished() signal is emitted. QFinalState is part of Qt State Machine Framework.
To use a final state, you create a QFinalState object and add a transition to it from another state. Example:
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();See Also▲
