Interface: FlexChild

Defined in: layout/flex.ts:17

Minimal child contract the flex strategy needs. Any object that exposes a size mode per axis and can be measured under constraints qualifies — the strategy never touches anything else, so it stays decoupled from SceneNode/TransformNode and is reusable outside the node tree.

Properties

gapScale?

optional gapScale?: number

Defined in: layout/flex.ts:33

Per-child gap weight in [0, 1] for animated insert/remove: the fraction of a full gap this child contributes on each of its sides. Undefined → 1 (normal layout). The animated addChildAt/removeChildAt overloads tween this 0 ↔ 1 so a collapsing/growing child opens or closes exactly one gap's worth of space in lockstep with its box.

heightMode

heightMode: SizeInput

Defined in: layout/flex.ts:19

mainFlex?

optional mainFlex?: number

Defined in: layout/flex.ts:25

Proportional weight for dividing the main-axis free space among fill children. Only consulted when this child fills the main axis; ignored otherwise. Undefined is treated as 1.

widthMode

widthMode: SizeInput

Defined in: layout/flex.ts:18
