title: Apply css on specific rows on javaFX
body: <p>I'm using a TreeTableView in my project, and I would like to do something specific when the user selects a row:</p>
  
  <p>I would like this row to have a different background color, but i would also like its childs and parents to have this color too.</p>
  
  <p>I found a way to access every rows and children, but I just don't know how to specify this background color. I tried to do this using my customs TreeTableCells and adding the style in my updateItem method, but this method is not called each time an item is selected.</p>
  
  <p>So i wanted to try to add listener in my treetableview, which seems to be a better idea, but in fact i'm not able to access the rows to give them any style.</p>
