Dear ZikO,

I unfortunately have another problem...

I successfully performed a connection between the comboBoxes, and the slot function, I'm only able to get the argument of the selected data, but not of the current ComboBox which has been clicked...

for (unsigned int row = 0; row < columns_number; row++)
connect(ComboBox[row], SIGNAL(currentIndexChanged(int)), this, SLOT(data_assign(int)));

Would you have any tip ??

Thanks in advance, and Best Regards !!

Stéphane
