Qt - QIcon in QTableWidget cell

Question

I have tried numerous ways to display a QIcon in a QTableWidget cell and I am not sure why it is not working. I have a button that when pressed adds a row to the table. Here is the code...

void MainWindow::pressed()
{
    QTableWidgetItem *item = new QTableWidgetItem("Hello, world!");
    QTableWidgetItem *icon_item = new QTableWidgetItem;
    QIcon icon("/verified/path/to/icon.png");
    icon_item->setIcon(icon);

    int row = ui->tableFeed->rowCount();
    ui->tableFeed->insertRow(row);
    ui->tableFeed->setItem(row, 0, icon_item);
    ui->tableFeed->setItem(row, 1, item);
}

And it just doesn't work. Nothing is displayed in that cell. Any ideas?

EDIT: the setItem call where I set it to icon was a typo. The actual code sets it to the QTabeWidgetItem icon_item. I have corrected it in the code above.

You have to set the icon to a QTableWidgetItem and then load the icon item and not the icon itself.

QTableWidgetItem *item = new QTableWidgetItem("Hello, world!");
QTableWidgetItem *icon_item = new QTableWidgetItem;
QIcon icon("/verified/path/to/icon.png"); // It is better to load the icon from the
                                          // resource file and not from a path 
icon_item->setIcon(icon);

int row = ui->tableFeed->rowCount();
ui->tableFeed->insertRow(row);
ui->tableFeed->setItem(row, 0, icon_item);
ui->tableFeed->setItem(row, 1, item);

If you can see the string item and not the icon then something is wrong with the icon path.
