QTableWidget test if the cell or item are empty

[jaca]

Hi!
I using Qt version 4.3.2.
How I make to test if the fields (cell or item) of QTableWidget are empty?
I made the test thus: testing row =0; and column = 0;

tableWidget = new QTableWidget(this);
tableWidget->setRowCount(3);
tableWidget->setColumnCount(3);
 
if (tableWidget->item(0,0)->text().isEmpty())
{
   ...
}

tableWidget = new QTableWidget(this);
tableWidget->setRowCount(3);
tableWidget->setColumnCount(3);

if (tableWidget->item(0,0)->text().isEmpty())
{
   ...
}

but without success.
