18.57 java.awt.TextArea (JDK 1.0)

This class is a GUI component that displays and optionally edits multi-line text. The appendText(), insertText(), and replaceText() provide various techniques for specifying text to appear in the TextArea. Many important TextArea methods are defined by the TextComponent superclass.

See also TextComponent and TextField.
