详细说明
最终状态用于表示（部分）QStateMachine 已完成其工作。当进入最终顶级状态时，状态机的finished()信号会被触发。 通常，当进入一个最终子状态（QState 的子状态）时，会发出父状态的finished()信号。QFinalState是Qt State Machine 框架的一部分。
要使用最终状态，需创建一个 QFinalState 对象，并从另一个状态向其添加过渡。示例：
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();另请参阅 QState::finished()。
成员函数文档
QFinalState::QFinalState(QState *parent = nullptr)
使用给定的parent 状态构建一个新的QFinalState对象。
[virtual noexcept] QFinalState::~QFinalState()
销毁此最终状态。
[override virtual protected] bool QFinalState::event(QEvent *e)
重写了：QAbstractState::event(QEvent *e)。
[override virtual protected] void QFinalState::onEntry(QEvent *event)
重写了：QAbstractState::onEntry(QEvent *event)。
[override virtual protected] void QFinalState::onExit(QEvent *event)
重写了：QAbstractState::onExit(QEvent *event)。
