setBounds on JScrollBar needs validate()?

Show all headers | View raw

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().
