title: JPanel doesn't show in BorderLayout
body: <p>I have a border layout, and a JPanel on the right. The JPanel has absolute layout, and it doesn't contain anything because I'm using it to draw graphics (overriding paintComponent(Graphics g))</p>
  
  <p>The problem is that the panel doesn't show (it's there but like 1 pixel wide). I tried to setSize on the panel.. but that doesn't work..</p>
  
  <p>How do I do it?</p>
  
  <pre><code>frame = new JFrame();
  frame.setBounds(100, 100, 450, 300);
  JPanel panelCenter = new JPanel();
  panelRight = new ActorDrawer();
  frame.getContentPane().add(panelRight, BorderLayout.EAST);
  panelRight.setSize(200, 400);
  panelRight.setLayout(null);
  frame.getContentPane().add(panelCenter, BorderLayout.CENTER);
  frame.getContentPane().add(panelBottom, BorderLayout.SOUTH);
  table = new JTable(new MyTableModel());
  JScrollPane scrollPane = new JScrollPane(table);
  table.setFillsViewportHeight(true);
  panelCenter.add(scrollPane);
  </code></pre>
