question: 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 do nothing (i.e. the response to properties in JTextComponent itself are handled prior to calling this method).
