QTableWidget

Hi, I'm trying to verify whether a QTableWidget is empty or partially empty, I want to assert that all cells of the table are filled out... before proceeding, how can I do this.. These are my silly attempts:

1st attempt

Code:

---

if (table->itemAt(1,i)->text().isEmpty())
{
      resultLabel->setText(QString("Please fill the table completely\n") +
      return false;
}

---

2nd attempt

Code:

---

if (!table->cellChanged(0,i))
{
      resultLabel->setText(QString("Please fill the table completely\n") +
      return false;
}

---

try

Code:

---

if (table->itemAt(1,i)->data(0).toString().isEmpty())
