Connect to the relevant signal?
You can get access to the scrollbars using QScrollArea::verticalScrollBar() and horizontalScrollBar().

have you tried to look in the docs?
There are signals for each value change.

You must not cast to QAbstractSlider pointer type. A QScrollBar inherits from QAbstractSlider, so you can safely assign directly:

@
QAbstractSlider *VBar= scrollArea->verticalScrollBar();
@

And you're better off to assign it to a QScrollBar pointer, to have access to the other methods too, if necessary. And yes, you do have access to QAbstractSlider's methods and signals too.
