The UITextField class defines the component used by many Flex components to display text. For example, the mx.controls.Button control uses a UITextField component to define the label area of the Button control.

The UITextField class extends the flash.text.TextField class to support additional functionality required by Flex, such as CSS styles, invalidation/measurement/layout, enabling/disabling, tooltips, and IME (Input Method Editor) support for entering Chinese, Japanese, and Korean text.
