public abstract class Item
extends Object

A superclass for components that can be added to a Form and Alert. All Item objects have a label field, which is a string that is attached to the item. The label is typically displayed near the component when it is displayed within a screen. This means that the implementation tries to keep the label on the same horizontal row with the item or directly above the item. If the screen is scrolling, the implementation tries to keep the label visible at the same time with the Item.

In some cases, when the user attempts to interact with an Item, the system will switch to a system-generated screen where the actual interaction takes places. If this occurs, the label will generally be carried along and displayed within this new screen in order to provide the user with some context for the operation. For this reason it is recommended that applications supply a label to all interactive Item objects. However, this is not required, and a null value for a label is legal and specifies the absence of a label.
