question: @ Override protected void paintTabBackground ( Graphics g , int tabPlacement , int tabIndex , int x , int y , int w , int h , boolean isSelected ) { if ( isSelected ) { if ( tabPlacement == TOP ) { g . setColor ( Color . white ) ; g . fillRoundRect ( x , y , w , h + R + R , R , R ) ; } } else { } }
target:  Give selected tab blue color with a gradient!!. FIXME: with Plastic L&F the unselected background is too dark
