Method Details

getRenderedComponent

public static Component getRenderedComponent(Grid.Column<?> column,
 String itemKey)

Gets the component the column has rendered for the item with the given key.

A component renderer keeps one component per item for as long as the client has the row, and that is the component the browser shows. Flow exposes no API for it: the mapping lives in AbstractComponentDataGenerator.renderedComponents, and the generator itself is reachable only through the private data generators of the column, so both are read reflectively. The accessor belongs upstream, on Grid.Column in vaadin/flow-components or on AbstractComponentDataGenerator in vaadin/flow.

Parameters:

column - the column that renders the cell

itemKey - key of the item the cell shows

Returns:

the rendered component, or null when the column has rendered no component for the item
