Problem with KeyPressEvent

[sali555]

Hi,
I have a problem with the event for Key_Space:
my code:

void MainWindow::keyPressEvent(QKeyEvent *event)
{
    switch (event->key()) {
    case Qt::Key_Space: // THIS DOESNT WORK
        qDebug() << "space";
        break;
 
    case Qt::Key_A: // THIS WORKS FINE
        qDebug() << "A";
        break;
    default:
        QWidget::keyPressEvent(event);
        break;
    }
}

void MainWindow::keyPressEvent(QKeyEvent *event)
{
    switch (event->key()) {
    case Qt::Key_Space: // THIS DOESNT WORK
        qDebug() << "space";
        break;

    case Qt::Key_A: // THIS WORKS FINE
        qDebug() << "A";
        break;
    default:
        QWidget::keyPressEvent(event);
        break;
    }
}

To copy to clipboard, switch view to plain text mode 

Do you know where is the mistake. Thx
