class: Scrollbar

[35:7] extends: object

Shows a horizontal or vertical scrollbar. 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). # 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 [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.
