DataGridRow

Row controller for a DataGrid.

A standalone, persistent plain class — one per data row — mirroring the DataGridColumn controller pattern (and deliberately not TableRow, which is itself an element). It is the source-of-truth object for a row and serves as the row handle: code may hold it whether or not the row is on-screen.

It owns its measured height (null until measured — mirroring how a column owns width), so heights travel with the record across sorts/splices. The dumb, pooled row element is referenced as this.element only while windowed; the cumulative offset is read from the grid's rowGeometry, not stored here.

Constructor

new DataGridRow(options)
options : Object
grid : DataGrid
index : number

0-based position in grid.rows

record : *

Instance Properties

P   offset

Cumulative top offset (px) in body space — read from the grid's rowGeometry.

Instance Methods

F   cellOf()

The live cell element for a column (by identity), or null when off-screen.

F   measure()

Measure the (auto-height) row element and record it on the controller. Returns true if the height changed (so the grid can reflow geometry).

F   mount()

Mount (or reposition) this row into the grid body.

F   position()

Position via transform (no layout cost beyond the transform).

F   unmount()

Detach: return cells + the row element to their pools and drop references.
