in SLOT: determine which signal sent the signal?

[vonCZ]

hello-

I have a slot with the following code:

QSlider *locSlider = qobject_cast<QSlider *>(sender());
QButtonGroup *locBG = qobject_cast<QButtonGroup *>(sender());
 
if(  QButtonGroup *locBG = qobject_cast<QButtonGroup *>(sender())  )
{  etc...  }
 
if(locSlider == zXag[2])
{  etc....  }
 
if( (locSlider == NULL)  &&  (locBG == NULL) )
{  etc...  }

QSlider *locSlider = qobject_cast<QSlider *>(sender());
QButtonGroup *locBG = qobject_cast<QButtonGroup *>(sender());

if(  QButtonGroup *locBG = qobject_cast<QButtonGroup *>(sender())  )
{  etc...  }

if(locSlider == zXag[2])
{  etc....  }

if( (locSlider == NULL)  &&  (locBG == NULL) )
{  etc...  }

To copy to clipboard, switch view to plain text mode 

and 3 things connected to the slot: a QSlider, a QButtonGroup, and a custom signal, customSG. This works: if customSG makes the call, the appropriate conditional is entered (i.e. when locSlider and locBG are NULL). But... what if I want to connect two Signals? How can I determine which Signal made the call? Or in such situations, should I just code a 2nd SLOT?
