Returns the state machine that this state is part of, or 0 if the state is not part of a state machine.

[pure virtual protected] void QAbstractState::onEntry(QEvent *event)

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.

[pure virtual protected] void QAbstractState::onExit(QEvent *event)

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.
