Detailed Description

The SignalEvent class represents a Qt signal event.

Since

4.6

A signal event is generated by a QStateMachine in response to a Qt signal. The QSignalTransition class provides a transition associated with a signal event. QStateMachine::SignalEvent is part of The State Machine Framework.

The sender() function returns the object that generated the signal. The signalIndex() function returns the index of the signal. The arguments() function returns the arguments of the signal.

Constructors and Destructors

SignalEvent()

QStateMachine::SignalEvent::SignalEvent	(	QObject *	sender,
