详细描述

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);
  machine.addState(s1);
  machine.addState(s2);

  QObject::connect(&machine, SIGNAL(finished()), QApplication::instance(), SLOT(quit()));
  machine.setInitialState(s1);
  machine.start();

参见 QState::finished().

成员函数

QFinalState::QFinalState(QState **parent* = Q_NULLPTR)

Constructs a new QFinalState object with the given parent state.
