#[repr(transparent)]pub struct Scrollbar { /* private fields */ }
Expand description
The Scrollbar
widget is a horizontal or vertical scrollbar.
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 by a page (using e.g. the Page Down/Up
keys).
CSS nodes
scrollbar
╰── range[.fine-tune]
╰── trough
╰── slider
Scrollbar
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
Scrollbar
uses the AccessibleRole::Scrollbar
role.

impl Scrollbar
sourcepub fn new(
orientation: Orientation,
adjustment: Option<&impl IsA<Adjustment>>
) -> Scrollbar
pub fn new(
orientation: Orientation,
adjustment: Option<&impl IsA<Adjustment>>
) -> Scrollbar
Creates a new scrollbar with the given orientation.
orientation
the scrollbar’s orientation.
adjustment
the Adjustment
to use, or None
to create a new adjustment.
Returns
the new Scrollbar
.
sourcepub fn builder() -> ScrollbarBuilder
pub fn builder() -> ScrollbarBuilder
Creates a new builder-pattern struct instance to construct Scrollbar
objects.
This method returns an instance of ScrollbarBuilder
which can be used to create Scrollbar
objects.
