Struct ScrollbarDefaults 

Source 
pub struct ScrollbarDefaults;
Expand description

Material Design 3 defaults for the scrollbar components.

A Material 3 scrollbar is a rounded thumb over the content; it has no persistent track. The thumb uses the on-surface hue at a low opacity so it stays legible on both light and dark surfaces.

The opacities are tuned for the renderer’s linear-space compositing so the resting thumb keeps a comparable weight to a Material scrollbar on a light surface.

Implementations§

Source§

impl ScrollbarDefaults

Source

pub const THICKNESS: Dp

Default scrollbar thickness.

Source

pub const THUMB_ALPHA: f32 = 0.5

Source

pub const THUMB_HOVER_ALPHA: f32 = 0.7

Thumb opacity while the pointer hovers or drags the thumb.

Source

pub fn thumb_color(scheme: &MaterialColorScheme) -> Color

Returns the default thumb color for the provided scheme.

Source

pub fn thumb_hover_color(scheme: &MaterialColorScheme) -> Color

Returns the thumb color used while hovering or dragging.
