Enum ScrollbarMode 

pub enum ScrollbarMode {
    Visible,
    Hidden,
    Auto,
}

When a scrolling node’s bars are drawn. Spelled by the scrollbar row (crate::schema::SCROLLBARS, in this order).

Variants

Visible

The stock bar: drawn whenever the content overflows.

Hidden

No thumb is drawn and no track takes the press. The wheel, the keyboard, reveal and the caret still scroll the node — a list drawing its own indicator, or one whose bar would sit on a border.

Auto

The bar shows while the scroll state is changing — the offset or the content’s extent moved since the last frame, the pointer is on its track, or a thumb is being dragged — and for a second after, then fades out over a quarter of one. A node first seen shows its bar the same second. What an overlay bar does on macOS. Needs the driver’s clock (Core::set_time); without one it is Visible, since a fade with no clock could never end.

Implementations

impl ScrollbarMode

pub const ALL: [ScrollbarMode; 3]

Every mode, in the scrollbar row’s order: what a binding that spells modes as numbers indexes (C’s KUI_SCROLLBAR_* are these plus one).
