All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, Accessible, Scrollable

public class JTextArea
extends JTextArea

This JTextArea autoselects in contents when the focus comes in and does some improved selection management. We need to override instead of using a decorator, because setText needs to be caught (especially when used as an editor in a JTextAreaSelectAll). NOTE: JTextArea, JTextField and JFormattedTextField all have an SelectAll version which are very similar. Maybe these can be combined?
