pub struct Scrollbar { /* private fields */ }
Expand description

The Scrollbar widget is a horizontal or vertical scrollbar, depending on the value of the property::Orientable::orientation property.

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

CSS nodes

⚠️ The following code is in plain ⚠️

scrollbar[.fine-tune]
╰── contents
    ├── [button.up]
    ├── [button.down]
    ├── trough
    │   ╰── slider
    ├── [button.up]
    ╰── [button.down]

GtkScrollbar has a main CSS node with name scrollbar and a subnode for its contents, with subnodes named trough and slider.

The main node gets the style class .fine-tune added when the scrollbar is in ‘fine-tuning’ mode.

If steppers are enabled, they are represented by up to four additional subnodes with name button. These get the style classes .up and .down to indicate in which direction they are moving.

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).
