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.

§content_margin: Margin

Extra margin added around the contents of a crate::ScrollArea.

The scroll bars will be either on top of this margin, or outside of it, depending on the value of Self::floating.

§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 is 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.

§fade: ScrollFadeStyle
