public class BasicTextAreaUI extends BasicTextUI
Provides the look and feel for a plain text editor. In this implementation the default UI is extended to act as a simple view factory.
Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

Description copied from class: BasicTextUI
Initializes component properties, such as font, foreground, background, caret color, selection color, selected text color, disabled text color, and border color.

protected void propertyChange(PropertyChangeEvent evt)
This method gets called when a bound property is changed on the associated JTextComponent. This is a hook which UI implementations may change to reflect how the UI displays bound properties of JTextComponent subclasses. This is implemented to rebuild the View when the WrapLine or the WrapStyleWord property changes.
