title: Modify SeaGlass JComponents
body: <p>I'm trying to create a variant of JTextField to make it look more like a 'search' field, I've seen this on the SeaGlass website but am having trouble implementing it... The look and feel itself work perfectly, but I cannot access the JTextField.variant method... I'm testing it a the following class: </p>
  
  <pre><code>public class Stuff extends JFrame {
  
      JTextArea text;
      JTextField field;
  
      public Stuff() {
          text = new JTextArea("something");
          text.setEditable(false);
          field = new JTextField(20).variant("search");            
          setLayout(new FlowLayout());            
          add(text);
          add(field);            
          setVisible(true);
          setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          setSize(600, 300);
      }
  }
  </code></pre>
  
  <p>and calling it in this class: </p>
  
  <pre><code>public class SeaGlassTest {
  
      /**
       * @param args the command line arguments
       */
      public static void main(String[] args) {
          try {
              UIManager.setLookAndFeel("com.seaglasslookandfeel.SeaGlassLookAndFeel");
              new Stuff();
          } catch (Exception e) {
              e.printStackTrace();
          }
      }
  }
  </code></pre>
