Struct Column 

pub struct Column {
    pub id: Option<NodeId>,
    pub children: Vec<Node>,
    pub semantics: Option<Semantics>,
    pub flex_grow: f32,
    pub flex_shrink: f32,
    pub gap: Option<f32>,
    pub wrap: FlexWrap,
    pub align_items: AlignItems,
    pub justify_content: JustifyContent,
}

A vertical flex container that lays out children in a column.

Children are arranged top-to-bottom. Use align_items to control cross-axis (horizontal) alignment and justify_content for main-axis (vertical) distribution.

Example

Column {
    children: vec![
        Text::new("Title").size(24.0).into_node().into(),
        Text::new("Subtitle").size(14.0).into_node().into(),
    ],
    gap: Some(4.0),
    align_items: AlignItems::Stretch,
    ..Default::default()
}

Fields

id: Option<NodeId>

Explicit node identity.

children: Vec<Node>

The child widgets laid out top-to-bottom.

semantics: Option<Semantics>

Custom semantics for accessibility.

flex_grow: f32

Flex grow factor.

flex_shrink: f32

Flex shrink factor.

gap: Option<f32>

Spacing between children in layout points.

wrap: FlexWrap

Whether children wrap when they overflow.

align_items: AlignItems

Cross-axis (horizontal) alignment (default: Stretch).

justify_content: JustifyContent

Main-axis (vertical) distribution (default: Start).
