Detailed Description

The PySide.QtCore.QFinalState class provides a final state.

A final state is used to communicate that (part of) a PySide.QtCore.QStateMachine has finished its work. When a final top-level state is entered, the state machine’s PySide.QtCore.QStateMachine.finished() () signal is emitted. In general, when a final substate (a child of a PySide.QtCore.QState ) is entered, the parent state’s PySide.QtCore.QState.finished() () signal is emitted. PySide.QtCore.QFinalState is part of The State Machine Framework .

To use a final state, you create a PySide.QtCore.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();
