QFinalState Class Reference
[QtCore module]

The QFinalState class provides a final state. More...

Inherits QAbstractState.


Detailed Description

The QFinalState class provides a final state.

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 The 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);

 QObject.connect(&machine, SIGNAL(finished()), QApplication.instance(), SLOT(quit()));
