how to connect different signals to one single slot?

slimhs

I want to connect some diffrent signals to the same slot. Is it possible?

@slimhs Sure is it possible as long as the signals provide the parameters the slot expects. Just connect each of the signals to the same slot.

slimhs

connect(button,SIGNAL(signal_1()),SIGNAL(signal_2()),this,SLOT(slot1()));
does this correct?

no you need to connect each signal separately with the slot.

Just a note: a signal is connectable with a slot if the slot has the same parameters or the slot less parameters. Means the following is also valid:

connect( sender, SIGNAL(signal(QString)), receiver, SLOT(slot()) );
connect( sender, SIGNAL(signal(int,QString), receiver, SLOT(slot(int)) );

so I can't push the diffrent signal in the same connect instruction?

QObject::connect is a static function, not an instruction, but yes, you can't do it in one call.

connect(button,SIGNAL(signal_1()),SIGNAL(signal_2()),this,SLOT(slot1()));
does this correct?

Syntax is :

connect(senderObject,SIGNAL(signalName()),receiverObject,SLOT(slotName()));
Both the signatures have to match.

Thanks,
