title: How does one make a component in the .CENTER of a Borderlayout occupy all center space and resize with the app?
body: <p>My app/JFrame, using Borderlayout, has a toolbar at the top or north, a statusbar at the bottom or south and a JPanel.JTabbedPane.JScrollPane.JTable in the center. The JPanel is always a fixed size which is roughly adjustable using the various set*Size() methods applied in various combinations to the various components. But it's always a fixed size and always has east and west gaps. The north and south components stay fixed height and resize horizontally as one would expect.</p>
  
  <p>Surely this is not a new or unique design.</p>
  
  <p>Is this normal behaviour?
  Is there some trick I've missed?</p>
