Basic Text Components - The Definitive Guide to Java Swing - page 514

JTextComponent Class
The JTextComponent class is the parent class for all the components used as textual views. It
describes the common behavior shared by all text components. Among other things, this common
behavior includes a Highlighter for selection support, a Caret for navigation throughout the
content, a set of commands supported through the actions property (an array of Action imple-
menters), a set of key bindings through a Keymap or InputMap / ActionMap combination, an
implementation of the Scrollable interface so that each of the specific text components can be
placed within a JScrollPane , and the text stored within the component. If that all sounds like a
lot to manage, don't worry. This chapter will guide you through each of the pieces.

JTextComponent Properties
Table 15-1 shows the 27 properties of JTextComponent . These properties cover the range of
capabilities you would expect from text components.
