Computes the content height without a trailing row gap

Available since @roku-sdk/flex-grid 3.3.0

import { computeTotalContentHeight } from "@roku-sdk/flex-grid/geometry";

Also exported as computeTotalContentHeight from @roku-sdk/flex-grid (deprecated).

Deprecated: computeTotalContentHeight. Import from @roku-sdk/flex-grid/geometry instead. The root export will be removed in the next major version.

computeTotalContentHeight(params: FixedFocusYParams): number

Description

Computes the content height without a trailing row gap.

Zero rows returns zero without calling either row accessor. Row indices are zero-based; positions and heights must describe the same content coordinate system.

Parameters

Return values

The last row start plus its height in pixels, or zero for no rows.

Example

computeTotalContentHeight({ containerY: 0, viewportHeight: 200, numRows: 2, getRowY: r => r * 100, getRowHeight: () => 100 }); // 200
