title: Using MigLayout, how can I make JPanel appear
body: <p>I have this ridiculously simple code (actually directly copied from the miglayout white paper: <a href="http://www.miglayout.com/whitepaper.html" rel="nofollow">http://www.miglayout.com/whitepaper.html</a>). I added the panel.setVisible(true) at the end. The problem is, with or without that last line, nothing shows up.</p>
  
  <pre><code>MigLayout layout = new MigLayout("fillx", "[right]rel[grow,fill]", "[]10[]");
  JPanel panel = new JPanel(layout);
  
  panel.add(new JLabel("Enter size:"),   "");
  panel.add(new JTextField(""),          "wrap");
  panel.add(new JLabel("Enter weight:"), "");
  panel.add(new JTextField(""),          "");
  panel.setVisible(true);
  </code></pre>
