[Qt-interest] Dialog box and signal/slot question

[Phil]

Thank you for reading this.

I've moved on somewhat from my previous question and now I'm stuck with 
a signal/slot connection.

This is how I add items to a table shown on a dialog:

void Configuration::showDialog(QString str)
{
  Configuration configDlg;

  for(int col = 0; col < 4; col++)
  {
    QTableWidgetItem *item = new QTableWidgetItem(list[col +1]);
    item->setTextAlignment(Qt::AlignHCenter);
    configDlg.freqTableWidget->setItem(row, col, item);
  }

I now want to access a particular row in the table so I've added the following 
line to my Configuration constructor:

connect(freqTableWidget, SIGNAL(cellActivated(int, int)), this, 
SLOT(selectRow(int, int)));

The problem is that activating a cell does not connect to the selectRow slot.

It seems to me that I need to add "configDlg" to the connect code. But 
configDlg is declared in the showDialog function and is not known to the 
constructor.

I've tried adding "Configuration configDlg" as a private attribute in the 
Configuration header file and I've tried a pointer as well and new in the 
constructor. None of these methods are correct.

The addressbook example is close to what I'm trying to achieve but it's a 
little complex and I cannot relate it to my particular case.

By the way, the Configuration class is not the main window.
