Detailed Description

The QtFinalState class provides a final state.

A final state is used to communicate that (part of) a QtStateMachine 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 QtState) is entered, a QtStateFinishedEvent is generated for the final state's parent state. QtFinalState is part of The State Machine Framework.

To use a final state, you create a QtFinalState object and add a transition to it from another state. Example:

 QPushButton button;

 QtStateMachine machine;
 QtState *s1 = new QtState();
 QtFinalState *s2 = new QtFinalState();
 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 QtStateFinishedTransition.

Constructs a new QtFinalState object with the given parent state.

QtFinalState::~QtFinalState ()

Destroys this final state.
