The gtk.Scrollbar widget is an abstract base class for gtk.HScrollbar and gtk.VScrollbar. The position of the thumb in a scrollbar is controlled by the scroll adjustments. The gtk.Scrollbar uses the attributes in an adjustment (see gtk.Adjustment) as follows:

the adjustment.lower attribute is the minimum value of the scroll region
the adjustment.upper attribute is the maximum value of the scroll region
the adjustment.value attribute represents the position of the scrollbar, which must be between adjustment.lower and adjustment.upper - adjustment.page_size
the adjustment.page_size attribute represents the size of the visible scrollable area
the adjustment.step_increment attribute is the distance to scroll when the small stepper arrows are clicked
the adjustment.page_increment attribute is the distance to scroll when the Page Up or Page Down keys are pressed
