Column

Column is a braced layout container whose main axis is vertical.

Arrange vertical content

Column {
  Text("Account", TextRole::Title),
  TextField(name).Label("Display name"),
  Button("Save").OnClick(SaveAccount),
}.With(
    Padding(24.0F),
    Spacing(12.0F),
    CrossAlign(CrossAxisAlignment::Stretch)
)

Spacing sets the gap between adjacent children. MainAlign distributes remaining vertical space; CrossAlign positions or stretches children horizontally. Children carrying Grow(factor) share available vertical space proportionally.

Preserve child order and identity

The container accepts individual View values and flattened Views groups from ForEach. Children retain declaration order for layout, painting, hit testing, and semantics.

API

• Construction: Column { children... } or an explicit std::vector<View> through its inherited Layout constructor.
• Layout modifiers: Spacing, MainAlign, CrossAlign, Padding, Frame.
• Child metadata: Grow.

Use Row for horizontal placement and Flow when items should wrap.
