question: public void updateUI ( ) { super . updateUI ( ) ; setBackground ( new Color ( 255 , 255 , 255 , 0 ) ) ; setWrapStyleWord ( true ) ; setHighlighter ( null ) ; setEditable ( false ) ; LookAndFeel . installBorder ( this , "Label.border" ) ; LookAndFeel . installColorsAndFont ( this , "Label.background" , "Label.foreground" , "Label.font" ) ; if ( resizeHandler != null ) { resizeHandler . componentResized ( null ) ; } SizePolicy policy = ( SizePolicy ) getClientProperty ( SizePolicy . class ) ; if ( policy != null ) { GUIUtils . restrictSize ( this , policy ) ; } }
target:  Tells the look and feel to reset some of the  values for this   component so that it doesn't use JTextArea's default values. DO NOT CALL THIS METHOD YOURSELF!
