Inherits from QObject.

Inherited by QFinalState, QHistoryState, QState.

Description露

The QAbstractState class is the base class of states of a QStateMachine.

The QAbstractState class is the abstract base class of states that are part of a QStateMachine. It defines the interface that all state objects have in common. QAbstractState is part of The State Machine Framework.

The entered signal is emitted when the state has been entered. The exited signal is emitted when the state has been exited.

The parentState() function returns the state鈥檚 parent state. The machine() function returns the state machine that the state is part of.

Subclassing露

The onEntry() function is called when the state is entered; reimplement this function to perform custom processing when the state is entered.

The onExit() function is called when the state is exited; reimplement this function to perform custom processing when the state is exited.
