title: BoxLayout Left Alignment
body: <p>I'm trying to left align the class and neutral buttons so they are in line with the left most card button. For some reason, setAlignmentX only shifts the buttons half way. Here is the code. Is there away to align the buttons?</p>
  
  <pre><code>private String[] listEntries = {"a","a","a","a","a"};
  private JButton remove = new JButton("Remove");
  private JList list;
  private JButton b1 = new JButton("Class");
  private JButton b2 = new JButton("Neutral");

      rightPanel.setBorder(BorderFactory.createEmptyBorder(10,10,10,10));
      leftPanel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
      JLabel title  = new JLabel("Deck Constructor", SwingConstants.CENTER);
      title.setBorder(BorderFactory.createEmptyBorder(10,0,0,0));
