I have created a component that extends JPanel and implements LayoutManager. This component contains a JScrollBar child. When my layoutContainer() method is called due to a resize, I call scrollbar.setBounds() and everything draws correctly. But when I need to reset the position of the scrollbar due to some internal action in my component, when I call scrollbar.setBounds() the scrollbar gets the correct size, but the arrows and slider are not updated unless I also call scrollbar.validate(). I would have thought that this would be done automatically when I resize the JScrollBar. This is the only component I have found that acts this way. For example, a JSlider repaints itself properly after setBounds(), without having to call validate().
