Struct Scroll 

pub struct Scroll {
    pub id: Option<NodeId>,
    pub child: Option<Box<Node>>,
    pub direction: FlexDirection,
    pub width: Option<f32>,
    pub height: Option<f32>,
    pub show_scrollbar: bool,
    pub flex_grow: f32,
    pub flex_shrink: f32,
}

A scrollable container that clips its child and tracks scroll offset.

Scroll direction can be horizontal (FlexDirection::Row) or vertical (FlexDirection::Column). The runtime manages scroll state automatically in response to pointer scroll events.

Example

Scroll {
    direction: FlexDirection::Column,
    show_scrollbar: true,
    flex_grow: 1.0,
    child: Some(Box::new(long_content)),
    ..Default::default()
}

Fields

id: Option<NodeId>

Explicit node identity (used for scroll-offset tracking).

child: Option<Box<Node>>

The scrollable content.

direction: FlexDirection

Scroll axis: Column for vertical, Row for horizontal.

width: Option<f32>

Fixed width in layout points.

height: Option<f32>

Fixed height in layout points.

show_scrollbar: bool

Whether to render a scrollbar indicator.

flex_grow: f32

Flex grow factor.

flex_shrink: f32

Flex shrink factor.
