title: TreeItem selection width in a TreeView
body: <p>I'm using JavaFX 8 and I'm currently doing some GUI developments. I have a little problem with my TreeView and I need your help.</p>
  
  <p>Do you know if it is possible, in a TreeView, to select just the label and not the whole width of the TreeCell ?</p>
