Scaffold

Scaffold is the canonical border layout. The center view is the required constructor argument; top, bottom, leading, and trailing edges are optional and attached via chain methods.

func Scaffold(center any) *viewNode
 
func (n *viewNode) Top(v any) *viewNode
func (n *viewNode) Bottom(v any) *viewNode
func (n *viewNode) Leading(v any) *viewNode
func (n *viewNode) Trailing(v any) *viewNode

Example

gova.Scaffold(
    gova.ScrollView(content),
).Top(
    gova.Text("Title").Font(gova.Title).Bold(),
).Bottom(
    gova.HStack(
        gova.TextField(input).Placeholder("...").Grow(),
        gova.Button("Send", onSend),
    ),
)

Why Scaffold, not Border

A positional Border(top, bottom, leading, trailing, center) is easy to write wrong. Named chain methods make intent explicit and allow omitting edges without nil placeholders.

Sizing

The center occupies all space the edges do not claim. Each edge uses its natural size along the axis it pins against. If you need more complex layout, nest a VStack or HStack inside the center.
