Qt: get text from button in QTableWidget

I have QTableWidget in my Qt application, and I add buttons to it like that:

QPushButton *startButton = new QPushButton("start");
ui->tableWidget_tvConnection->setCellWidget(row, col, startButton);
connect(startButton, SIGNAL(clicked()), this, SLOT(startButtonPressed()));

And when it is pressed I need to get text from it, so I tried this:

void MainWindow::startButtonPressed()
{
    ...
    QPushButton *button = ui->tableWidget_tvConnection->cellWidget(row, col);
    qDebug() << button->text();
}

But compiler doesn't allow me to convert from QWidget* to QPushButton*:

error: invalid conversion from 'QWidget*' to 'QPushButton*' [-fpermissive]

So Is it even possible to get text from button inside QTableWidget? If it isn't I have another way how to handle this in my application, but this would be really nice.

You get QWidget, so you should cast it to QPushButton. After that, you will be able to use this as a normal pushbutton. Try this:

QPushButton *button = qobject_cast<QPushButton *>(ui->tableWidget_tvConnection->cellWidget(row, col));

if(button) {
    //success
} else {
    //bad
}
