Its position and movement are controlled by the adjustment that is passed to or created by Scrollbar(). See Adjustment for more details. The Gtk.Adjustment:value field sets the position of the thumb and must be between Gtk.Adjustment:lower and Gtk.Adjustment:upper - Gtk.Adjustment:page-size. The Gtk.Adjustment:page-size represents the size of the visible scrollable area.

The fields Gtk.Adjustment:step-increment and Gtk.Adjustment:page-increment fields are added to or subtracted from the 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).

CSS nodes


 scrollbar
 ╰── range[.fine-tune]
     ╰── trough
         ╰── slider

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 ScrolledWindow include the positional classes (.left, .right, .top, .bottom) and style classes related to overlay scrolling (.overlay-indicator, .dragging, .hovering).

Accessibility
GtkScrollbar uses the Gtk.AccessibleRole.scrollbar role.
