RowWindow

Which rows a scroll offset makes visible, so that a list costs a screenful rather than a list.

interface RowWindow

import type { RowWindow } from '@driftengine/ui2d';

In depth

An asset browser with ten thousand entries has to cost what a screenful costs. Without this the scene tree is unusable the first time somebody opens a real project, which is the moment nobody wants to discover it.

Overscan is applied before clamping, not after. Applied after, a window near either end runs past the row count and a caller indexes rows that do not exist.
