JavaFX 2 TreeView Styling - lines from parents to children

问题

I have a pretty big structure of data, which I want to show in the TreeView. When a lot of branches and sub-branches are opened, it's not clear what belongs to what.

Is there a way (CSS?) how to style the TreeView, so it will be showing the lines from parents to children like in Swing?

Thank you for any ideas...
