## Arguments

`Item` |  | The component to extract.

## Function result

The extracted component, or Nil if none was found.

## Description

Extract removes a component (Item) from the list, without destroying it. It overrides the implementation of TObjectList so only TComponent descendents can be extracted. It introduces no new behaviour.
