Placeable

A child that has been laid out and knows its size, but not yet where it sits.

Only the framework can make one — the constructor is internal — which is what lets PlacementScope.place trust childIndex. place is an extension on this type rather than a function taking an index, so the index travels with the placeable and cannot be fabricated to place a child at the wrong slot.

Properties

height

val height: Int

The height this child occupies, margins included, within the constraints it was measured at.

measuredHeight

val measuredHeight: Int

The height this child asked for. The other axis of measuredWidth.

measuredWidth

val measuredWidth: Int

The width this child asked for, margins included, before it was kept within its constraints. Differs from width only when the child does not fit them: it is then centred in width.

width

val width: Int

The width this child occupies, margins included, within the constraints it was measured at.
