title: How to hide scrollbars in the JavaFX WebView
body: <p>I'm trying to remove the scrollbars in a javafx webview. 
  Search on forums, the suggestion is to make them invisible as follows:</p>
  
  <pre><code>browser.getChildrenUnmodifiable().addListener(new ListChangeListener&lt;Node&gt;() {
      @Override public void onChanged(Change&lt;? extends Node&gt; change) {
          Set&lt;Node&gt; deadSeaScrolls = browser.lookupAll(".scroll-bar");
          for (Node scroll : deadSeaScrolls) {
              scroll.setVisible(false);
          }
      }
  })
  </code></pre>
  
  <p>However, I receive the following error:</p>
  
  <p>"trait ListChangeListener is abstract; cannot be instantiated"</p>
  
  <p>I can understand why its failing, but then again, why are people using this code with success? I'm using Eclipse and the code is surrounded in Scala code.</p>
  
  <p>Thanks!
  S</p>
