Setting areas of MainWindow that are click responsive

[yonibr]

I am working on a tic tac toe program. At the moment, I am trying to make it so that you can click where you want the "x" to go. I currently have an event handler for a mouse click:

void QWidget::mousePressEvent ( QMouseEvent *event )
{
    QPoint mousePos = mapFromGlobal(QCursor::pos());
}

void QWidget::mousePressEvent ( QMouseEvent *event )
{
    QPoint mousePos = mapFromGlobal(QCursor::pos());
}

My goal now is to set up 9 different areas in the main window. I then want to determine which area received the click. What would these functions look like?
The 9 areas would fall in between the squares of the tic tac toe board. The function that draws that is here:

void MainWindow::paintEvent(QPaintEvent *event)
{
    QPainter painter(this);
 
    // Draw Tic Tac Toe Board
    painter.setRenderHint(QPainter::Antialiasing, true);
    painter.setPen(QPen(Qt::black, 10, Qt::SolidLine, Qt::RoundCap,
                    Qt::MiterJoin));
    painter.drawLine(80, 20, 80, 250);
 
    painter.setRenderHint(QPainter::Antialiasing, true);
    painter.setPen(QPen(Qt::black, 10, Qt::SolidLine, Qt::RoundCap,
                    Qt::MiterJoin));
    painter.drawLine(170, 20, 170, 250);
 
    painter.setRenderHint(QPainter::Antialiasing, true);
    painter.setPen(QPen(Qt::black, 10, Qt::SolidLine, Qt::RoundCap,
                    Qt::MiterJoin));
    painter.drawLine(10, 90, 250, 90);
 
    painter.setRenderHint(QPainter::Antialiasing, true);
    painter.setPen(QPen(Qt::black, 10, Qt::SolidLine, Qt::RoundCap,
                    Qt::MiterJoin));
    painter.drawLine(10, 180, 250, 180);
}

void MainWindow::paintEvent(QPaintEvent *event)
{
    QPainter painter(this);

    // Draw Tic Tac Toe Board
    painter.setRenderHint(QPainter::Antialiasing, true);
    painter.setPen(QPen(Qt::black, 10, Qt::SolidLine, Qt::RoundCap,
                    Qt::MiterJoin));
    painter.drawLine(80, 20, 80, 250);

    painter.setRenderHint(QPainter::Antialiasing, true);
    painter.setPen(QPen(Qt::black, 10, Qt::SolidLine, Qt::RoundCap,
                    Qt::MiterJoin));
    painter.drawLine(170, 20, 170, 250);

    painter.setRenderHint(QPainter::Antialiasing, true);
    painter.setPen(QPen(Qt::black, 10, Qt::SolidLine, Qt::RoundCap,
                    Qt::MiterJoin));
    painter.drawLine(10, 90, 250, 90);

    painter.setRenderHint(QPainter::Antialiasing, true);
    painter.setPen(QPen(Qt::black, 10, Qt::SolidLine, Qt::RoundCap,
                    Qt::MiterJoin));
    painter.drawLine(10, 180, 250, 180);
}

Thanks for the help

There is a tic tac toe implementation available in Qt docs. Have a look at it.

Thanks, but is there a way to do it without Qt Quick?
Edit: And I don't want the "x"s and "o"s to be buttons. I have the code to draw them done already. I just need code to draw them where the click happens.

The example I mean is not using Qt Quick.
