Struct ScrollbarSpec 

pub struct ScrollbarSpec {
    pub thickness: f32,
    pub min_thumb_extent: f32,
    pub corner_radius: Option<f32>,
    pub colors: ScrollbarColors,
    pub hide_when_content_fits: bool,
}

How a Scrollbar is drawn and how short its thumb may get.

Fields

thickness: f32

Width across the short axis.

min_thumb_extent: f32

The shortest the thumb may get, in logical pixels.

corner_radius: Option<f32>

Corner radius of the track and the thumb. Defaults to a full pill.

colors: ScrollbarColors

Colors of the track and the thumb.

hide_when_content_fits: bool

Whether the bar disappears entirely when the content fits.

A bar left visible over content that cannot scroll invites a drag that does nothing.

Implementations

impl ScrollbarSpec

pub fn thickness(self, thickness: f32) -> Self

Sets the width across the short axis, in logical pixels. Negative values count as zero.

pub fn min_thumb_extent(self, extent: f32) -> Self

Sets the shortest the thumb may get, in logical pixels. Negative values count as zero.

pub fn corner_radius(self, radius: f32) -> Self

Sets the corner radius of the track and the thumb, in logical pixels. Negative values count as zero.

pub fn colors(self, colors: ScrollbarColors) -> Self

Sets the colors of the track and the thumb.

pub fn hide_when_content_fits(self, hide: bool) -> Self

Sets whether the bar disappears when the content fits.

pub fn resolved_corner_radius(&self, thickness: f32) -> f32

The corner radius to paint with on a bar of this thickness: a full pill unless the caller asked for something squarer.

pub fn thumb_bounds(&self, track: f32) -> ThumbBounds

How short the thumb may get on a track of track, as a fraction.
