Public methods

layout

open fun layout(
    width: Int,
    height: Int,
    alignmentLines: Map<AlignmentLine, Int> = emptyMap(),
    placementBlock: Placeable.PlacementScope.() -> Unit
): MeasureResult

Sets the size and alignment lines of the measured layout, as well as the positioning block that defines the children positioning logic. The placementBlock is a lambda used for positioning children. Placeable.placeAt should be called on children inside placementBlock. The alignmentLines can be used by the parent layouts to decide layout, and can be queried using the Placeable.get operator. Note that alignment lines will be inherited by parent layouts, such that indirect parents will be able to query them as well.
