Member Function Documentation

void pcl::cloud_composer::SignalMultiplexer::connect	(	QObject *	sender,
		const char *	signal,
		const char *	slot
	)

Use this connect function instead of QObject::connect() to connect an actions activation signal to the receiving, multiplexed object.

Parameters:

sender	the sending action or object
signal	the signal in the sender object that is connected to
slot	the slot in the receiving object that is set through setCurrentObject that the signal should be connected to.

void pcl::cloud_composer::SignalMultiplexer::connect	(	const char *	signal,
		QObject *	receiver,
		const char *	slot
	)

Use this connect function instead of QObject::connect() to connect a multiplexed object's (status) signal to an action object's slot.

Parameters:

signal	the signal in the multiplexed sender object that is set through setCurrentObject that the connection should be from
receiver	the receiving action or object
slot	the slot in the receiving object

bool pcl::cloud_composer::SignalMultiplexer::disconnect	(	QObject *	sender,
		const char *	signal,
		const char *	slot
	)

Disconnects a signal connection from a sending object to a multiplexed receiving object.

bool pcl::cloud_composer::SignalMultiplexer::disconnect	(	const char *	signal,
		QObject *	receiver,
		const char *	slot
	)

Disconencts a signal from a multiplexed object to a receiving (action) object.

void pcl::cloud_composer::SignalMultiplexer::setCurrentObject

(

QObject *

newObject

)

[slot]

Sets the current object the signals that are managed by the SignalMultiplexer instance should be connected to. Any connections of these signals to the previous object will be disconnected. After the connections are hooked to the new object, the currentObjectChanged signal will be emitted.

Parameters:

newObject

the new object that the signals should be connected to
