// Its position and movement are controlled by the adjustment that is passed to
// or created by [ctor@Gtk.Scrollbar.new]. See [class@Gtk.Adjustment] for more
// details. The [property@Gtk.Adjustment:value] field sets the position of the
// thumb and must be between [property@Gtk.Adjustment:lower] and
// [property@Gtk.Adjustment:upper] - [property@Gtk.Adjustment:page-size].
// The [property@Gtk.Adjustment:page-size] represents the size of the visible
// scrollable area.
//
// The fields [property@Gtk.Adjustment:step-increment] and
// [property@Gtk.Adjustment:page-increment] fields are added to or subtracted
// from the [property@Gtk.Adjustment:value] when the user asks to move by a step
// (using e.g. the cursor arrow keys) or by a page (using e.g. the Page Down/Up
// keys).

//
// `GtkScrollbar` has a main CSS node with name scrollbar and a subnode for its
// contents. The main node gets the .horizontal or .vertical style classes applied,
// depending on the scrollbar's orientation.
//
// The range node gets the style class .fine-tune added when the scrollbar is
// in 'fine-tuning' mode.
//
// Other style classes that may be added to scrollbars inside
// [class@Gtk.ScrolledWindow] include the positional classes (.left, .right,
// .top, .bottom) and style classes related to overlay scrolling (.overlay-indicator,
// .dragging, .hovering).
//
// # Accessibility
//
// `GtkScrollbar` uses the [enum@Gtk.AccessibleRole.scrollbar] role.
