Constructors¶

BoxMeasurePolicy¶

constructor(alignment: Alignment)

Properties¶

arrangementSpacing¶

val arrangementSpacing: Int

Parameters

arrangementSpacing: Additional pixels added between siblings by the arrangement.

sumHeight¶

val sumHeight: Boolean

Parameters

sumHeight: When true, each child's height is subtracted from the remaining max-height before the next child is measured (Column behaviour).

sumWidth¶

val sumWidth: Boolean

Parameters

sumWidth: When true, each child's width is subtracted from the remaining max-width before the next child is measured (Row behaviour).

Functions¶

measure¶

open override fun measure(
    scope: MeasureScope, 
    measurables: List<Measurable>, 
    constraints: Constraints
): MeasureResult

Measures measurables within constraints and returns a MeasureResult.

Parameters

scope: The LayoutNode currently being measured (implements MeasureScope).
measurables: The child nodes to measure.
constraints: The size constraints imposed by the parent.

placeChildren¶

open override fun placeChildren(
    scope: MeasureScope, 
    measurables: List<Measurable>, 
    placeables: List<Placeable>, 
    width: Int, 
    height: Int
): MeasureResult

Positions all measured placeables within width × height and returns the MeasureResult.

Parameters

scope: The measuring LayoutNode.
measurables: The original measurables (for modifier access).
placeables: The measured placeables to position.
width: The resolved container width.
height: The resolved container height.
