Hi hapciu,

JScrollbar may use subcomponents for arrow buttons.

Try to make a ScrollBarUI subclass instead (javax.swing.plaf package), and use it with your scrollbar:

  jscrollbar.setUI( new <yoursubclass_of_scrollbarUI>());

override the paint(Graphics g, JComponent c) method.

Since no method is abstract in ScrollBarUI or in its super classes, once you create a subclass of ScrollBarUI, you get a concrete class.
