question: @ Override protected void propertyChange ( PropertyChangeEvent evt ) { if ( SeaGlassLookAndFeel . shouldUpdateStyle ( evt ) ) { updateStyle ( ( JTextComponent ) evt . getSource ( ) ) ; } super . propertyChange ( evt ) ; }
target:  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 ActionMap based upon an EditorKit change.
