title: How to grow Labels within a VBox
body: <p>I got the following setup:</p>
  
  <pre><code>Label errorLabel = new Label("Hello Hans");
  Label warningLabel = new Label("HEEELLLOOOOOOOOOOOOOOOOOOOOOOOOO");
  VBox box = new VBox();
  box.getChildren().addAll(errorLabel, warningLabel);
  Tooltip t = new Tooltip();
  t.setGraphic(box);
  t.show();
  </code></pre>
  
  <p>My problem is, that <code>warningLabel</code> and <code>errorLabel</code> have different sizes. They should both grow to the same size horizontally. I don't want to put a specific size. The size of both must be whichever label needs more to display the whole text.</p>
  
  <p>The problem is, that both Labels have a background and you can see that the warningLabel takes more space. I need both backgrounds of those label grow equally.</p>
