signals and control arrays

[zorro68]

I have read obout sender() function and I need more help. I have programm this:

for (int i=0;i<max_contorno;i++){
		connect(SLDpaso[i], SIGNAL(valueChanged(int)), this, SLOT(setIsoValueInt(int)));
}

for (int i=0;i<max_contorno;i++){
		connect(SLDpaso[i], SIGNAL(valueChanged(int)), this, SLOT(setIsoValueInt(int)));
}

To copy to clipboard, switch view to plain text mode 

and in setIsoValueInt:

QSlider *SLDp = (QSlider *)sender();

QSlider *SLDp = (QSlider *)sender();

To copy to clipboard, switch view to plain text mode 

But i dont know how to obtain the index of the Sliders array

There:

int sldIndex = -1;
for(int i = 0; i != max_contorno; ++i)
  if(SLDpaso[i] == SLDp) 
  {
     sldIndex = i;
     break;
  }

int sldIndex = -1;
for(int i = 0; i != max_contorno; ++i)
  if(SLDpaso[i] == SLDp) 
  {
     sldIndex = i;
     break;
  }

To copy to clipboard, switch view to plain text mode 

So, you should test sldIndex to be a valid value.
