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's parent state. The machine() function returns the state machine that the state is part of.
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.
Constructs a new state with the given parent state.
Destroys this state.
This signal is emitted when the state has been entered (after onEntry() has been called).
Reimplemented from QObject::event().
This signal is emitted when the state has been exited (after onExit() has been called).
Returns the state machine that this state is part of, or 0 if the state is not part of a state machine.
This function is called when the state is entered. The given event is what caused the state to be entered. Reimplement this function to perform custom processing when the state is entered.
This function is called when the state is exited. The given event is what caused the state to be exited. Reimplement this function to perform custom processing when the state is exited.
Returns this state's parent state, or 0 if the state has no parent state.
