title: JavaFX TreeView lines
body: <p>I often wonder why JavaFX does'nt provide an option to show tree lines in TreeView. I tried to search if someone has come up with an approach/solution/tweak. But could'nt find any.</p>
  <p>This is the most common implementation for tree structure. Do someone know why JavaFX didnt provide this feature? Is it because of any unavoidable issues or any performance related issues or is it pure design choice ?</p>
