public class JLabeledTextArea
extends JPanel
implements JLabeledField, FocusListener

A Helper component that wraps a JTextField with a label into a JPanel (this). This component also has an efficient event handling mechanism for handling the text changing in the Text Field. The registered change listeners are only called when the text has changed.
