title: JavaFX ListView on scroll show
body: <p>I was wandering, is there a property, to which I can attach a listener, that represents the action of "When the list view starts to show the ScrollBar"?</p>
  
  <p>The thing is, that I have an output to the ListView, and at some point the ListView's scrollBar triggers. I want to capture that event and scroll to the bottom so the next addition to the ListView object will automatically scroll to the bottom.</p>
  
  <p>I do understand that I may use the listener for the item change, but I want to preserve the behavior when I decide to scroll up and it will not scroll back to the last position as soon as an item gets added.</p>
