title: JavaFX TreeView: remove expand / collapse button (disclosure node) & functionality
body: <p>I want to have a TreeView that has all of its children permanently expanded, and I don't want the user to be able to expand or collapse any of the children.</p>
  
  <p>To do this I've found that I need to do the following:</p>
  
  <ul>
  <li>Remove icon with CSS (Done)
  
  <ul>
  <li><a href="https://stackoverflow.com/questions/15521806/change-expand-and-collapse-image-treeview-javafx-2-2">Change expand and collapse image TreeView JavaFX 2.2</a></li>
  <li>[edit] Above link should be used to change image; to remove completely, use this solution: <a href="https://stackoverflow.com/a/27831191/4430591">https://stackoverflow.com/a/27831191/4430591</a></li>
  </ul></li>
  <li>Remove double click functionality (Done)
  
  <ul>
  <li><a href="https://stackoverflow.com/questions/15509203/disable-treeitems-default-expand-collapse-on-double-click-javafx-2-2">Disable TreeItem&#39;s default expand/collapse on double click JavaFX 2.2</a></li>
  </ul></li>
  <li>[edit] Remove ability to collapse / expand using keyboard arrrow keys (Done)
  
  <ul>
  <li>Given in José Pereda's solution below ( <a href="https://stackoverflow.com/a/27831085/4430591">https://stackoverflow.com/a/27831085/4430591</a> )</li>
  </ul></li>
  <li>[edit] Remove ability to right click for a ContextMenu (Done)
  
  <ul>
  <li>Given in José Pereda's solution below ( <a href="https://stackoverflow.com/a/27831085/4430591">https://stackoverflow.com/a/27831085/4430591</a> )</li>
  </ul></li>
  <li><strong>Remove icon's clickablity (How do I do this?)</strong>
  
  <ul>
  <li>[edit] solution: <a href="https://stackoverflow.com/a/27831191/4430591">https://stackoverflow.com/a/27831191/4430591</a></li>
  </ul></li>
  </ul>
  
  <p>Even though the icon is no longer visible, it's still clickable. I don't see any way of filtering this; I only see ways to be able to respond to it after the fact.</p>
  
  <p>Also, if I'm missing anything else that I need to do to ensure this functionality, please let me know.</p>
