.GtkScrollbar
widget is an abstract base class for GtkHScrollbar
and
GtkVScrollbar
. It is not very useful in itself. The position of the thumb in a scrollbar is controlled by the scroll
adjustments. See GtkAdjustment
for the fields in an adjustment - for
GtkScrollbar
, the "value" field represents the position of the
scrollbar, which must be between the "lower" field and "upper -
page_size." The "page_size" field represents the size of the visible
scrollable area. The "step_increment" and "page_increment" fields are
used when the user asks to step down (using the small stepper arrows)
or page down (using for example the PageDown key).fixed-slider-length
