title: Modify the scroll button of a JTabbedPan
body: <p>I'm working on a UI on Java with Swing, I want to change the scroll button of a JTabbedPane, so I use a new UI (MyTabbedPaneUI) that I create from the extends MetalTabbedPaneUI.</p>
  
  <p>But when I create my JTabbedPanel there are 2 tabs which appear and I don't want them. If I remove them my scroll bar disappear.</p>
  
  <p>The code :</p>
  
  <pre><code>  public class MyTabbedPaneUI extends MetalTabbedPaneUI{
  
          private Icon southIcon = new ImageIcon(MyTabbedPaneUI.class.getResource("south.png"));
          private Icon northIcon = new ImageIcon(MyTabbedPaneUI.class.getResource("north.png"));
          private Icon eastIcon  = new ImageIcon(MyTabbedPaneUI.class.getResource("flecheVerte-gauche-20px.png"));
          private Icon westIcon  = new ImageIcon(MyTabbedPaneUI.class.getResource("flecheVerte-droite-20px.png"));
  
  
          public static ComponentUI createUI( JComponent x ) {
              return new MyTabbedPaneUI();
          }
  
  
          @Override
          protected JButton createScrollButton(int direction) {
  
              if ((direction != SOUTH) &amp;&amp; (direction != NORTH) &amp;&amp; (direction != EAST) &amp;&amp; (direction != WEST)) {
                  throw new IllegalArgumentException("Direction must be one of: " + "SOUTH, NORTH, EAST or WEST");
              }
  
  
              JButton b = new JButton();
  
              //b.setText("");
              b.setPreferredSize(new Dimension(eastIcon.getIconWidth(), eastIcon.getIconHeight()));
  
              if (direction == SOUTH) {
                  b.setIcon(southIcon);
              } else if (direction == NORTH) {
                  b.setIcon(northIcon);
              } else if (direction == WEST) {
                  b.setIcon(westIcon);
              } else {
                  b.setIcon(eastIcon);
              }
  
              return b;
          }
  
      }
