Expand description

Controls the spacing and visuals of a crate::ScrollArea.

There are three presets to chose from:

Fields§

§floating: bool

If true, scroll bars float above the content, partially covering it.

If false, the scroll bars allocate space, shrinking the area available to the contents.

This also changes the colors of the scroll-handle to make it more promiment.

§bar_width: f32

The width of the scroll bars at it largest.

§handle_min_length: f32

Make sure the scroll handle is at least this big

§bar_inner_margin: f32

Margin between contents and scroll bar.

§bar_outer_margin: f32

Margin between scroll bar and the outer container (e.g. right of a vertical scroll bar). Only makes sense for non-floating scroll bars.

§floating_width: f32

The thin width of floating scroll bars that the user is NOT hovering.

When the user hovers the scroll bars they expand to Self::bar_width.

§floating_allocated_width: f32

How much space i allocated for a floating scroll bar?

Normally this is zero, but you could set this to something small like 4.0 and set Self::dormant_handle_opacity and Self::dormant_background_opacity to e.g. 0.5 so as to always show a thin scroll bar.

§foreground_color: bool

If true, use colors with more contrast. Good for floating scroll bars.

§dormant_background_opacity: f32

The opaqueness of the background when the user is neither scrolling nor hovering the scroll area.

This is only for floating scroll bars. Solid scroll bars are always opaque.

§active_background_opacity: f32

The opaqueness of the background when the user is hovering the scroll area, but not the scroll bar.

This is only for floating scroll bars. Solid scroll bars are always opaque.

§interact_background_opacity: f32

The opaqueness of the background when the user is hovering over the scroll bars.

This is only for floating scroll bars. Solid scroll bars are always opaque.

§dormant_handle_opacity: f32

The opaqueness of the handle when the user is neither scrolling nor hovering the scroll area.

This is only for floating scroll bars. Solid scroll bars are always opaque.

§active_handle_opacity: f32

The opaqueness of the handle when the user is hovering the scroll area, but not the scroll bar.

This is only for floating scroll bars. Solid scroll bars are always opaque.

§interact_handle_opacity: f32

The opaqueness of the handle when the user is hovering over the scroll bars.

This is only for floating scroll bars. Solid scroll bars are always opaque.

Implementations§

source§

impl ScrollStyle

source

pub fn solid() -> Self

Solid scroll bars that always use up space

source

pub fn thin() -> Self

Thin scroll bars that expand on hover

source

pub fn floating() -> Self

No scroll bars until you hover the scroll area, at which time they appear faintly, and then expand when you hover the scroll bars.

source

pub fn allocated_width(&self) -> f32

Width of a solid vertical scrollbar, or height of a horizontal scroll bar, when it is at its widest.
