QFinalState露
- PyQt5.QtCore.QFinalState
Inherits from QAbstractState.
Description露
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鈥檚 finished() signal is emitted. In general, when a final substate (a child of a QState) is entered, the parent state鈥檚 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);
machine.addState(s1);
machine.addState(s2);
QObject::connect(&machine, SIGNAL(finished()), QApplication::instance(), SLOT(quit()));
machine.setInitialState(s1);
machine.start();
