Col

Vertical flex layout container. Distributes available height among children.

Constructor

new Col(children: (Component | ColChild)[])

Plain Component values are wrapped as { component, flex: 1 }.

ColChild

interface ColChild {
  component: Component
  height?: number  // fixed height in rows
  flex?: number    // flex factor (default: 1)
}

Methods

render()

render(width: number, height: number): CharGrid

Same algorithm as Row but for vertical space. Fixed-height children first, then flex distribution.

Examples

// header + body + footer
new Col([
  { component: header, height: 3 },
  { component: body, flex: 1 },
  { component: footer, height: 1 },
])

// equal split
new Col([panelA, panelB])
