title: How to make TabPane borders green
body: <p>I implemented drag and drop example from the JavaFX tutorial.</p>
  
  <p>And I managed to add effect when I drag a tab over a target TabPane:</p>
  
  <pre><code>tabPane.setOnDragEntered(new EventHandler&lt;DragEvent&gt;() {
              @Override
              public void handle(DragEvent event) {
                  /* the drag-and-drop gesture entered the target */
                  /* show to the user that it is an actual gesture target */
                  if (event.getGestureSource() != tabPane
                          &amp;&amp; event.getDragboard().hasString()) {
                      tabPane.setCursor(Cursor.MOVE);
  
  
                      tabPane.setEffect(new Glow());
                  }
  
                  event.consume();
              }
          });
  
          tabPane.setOnDragExited(new EventHandler&lt;DragEvent&gt;() {
              @Override
              public void handle(DragEvent event) {
                  /* mouse moved away, remove the graphical cues */
                  tabPane.setCursor(Cursor.DEFAULT);
  
                  tabPane.setEffect(null);
  
                  event.consume();
              }
          });
  </code></pre>
  
  <p>But I would like to to make the borders of the target TabPane green instead of adding Glow effect. Is this possible?</p>
