How to get mouse press position relative to QScrollArea's widget

Question

If I have a wide widget in a QScrollArea, and I press the mouse on it, then I get a mouse position (in mousePressEvent()) relative to the scroll area (if I scroll, it changes).

How can I get the mouse position relative to that wide widget inside the scroll area?

I tried to use a combination of functions mapTo(), parentWidget(), viewport() and had no success.

At the moment I've got three similiar ways that work quite fine for me.

class MyWidget : public QScrollArea
{
// ...
};

void MyWidget::mousePressEvent(QMouseEvent *event)
{
    qDebug() << widget()->mapFromGlobal(QCursor::pos());     // 1
    qDebug() << widget()->mapFrom(viewport(), event->pos()); // 2
    qDebug() << widget()->mapFromParent(event->pos());       // 3
}
