title: How do I programmatically control the position of JScrollPane?
body: <p>I have a <code>JScrollPane</code> containing a <code>JPanel</code> and, in turn, a <code>JList</code>.  I want for the viewport to always show the <em>end</em> of the list (from which items are being removed or added).  I can accomplish this manually by dragging the <code>ScrollBar</code> to the bottom, where it stays, just the way I want it to.  What should I do to accomplish this automatically?</p>
