title: Fit VBox to parent GridPane
body: <p>I have GridPane which has two columns: first contains fixed-size ImageView, the second has VBox with Text elements. I need this VBox to fit the column width. Grid has right dimensions, ImageView too, but VBox in second column fits to text which it contains, not to parent (grid).</p>
  
  <pre><code>VBox box = new VBox();
  // all three texts can be changed during program execution by user
  // (so 'box' width cannot be based on children widths)
  box.getChildren().addAll(new Text("1"), new Text("2"), new Text("3"));
  box.setStyle("-fx-background-color: red;");
  
  Image image = ...; // image is always 150x150 px
  ImageView imgView = new ImageView(image);
  GridPane grid = new GridPane();
  grid.add(imgView, 0,0);
  grid.add(box,1,0);
  grid.add(new Text("another content"), 0,1,2,1);
  </code></pre>
  
  <p>According to given example i want 'box' to have the same width as second column of 'grid' object.
  How to fix this?</p>

  Container with green border: GridPane grid
  Container with lightblue border: VBox box
  GridPane has red background, VBox has pink background. You can see that it clearly DOES NOT fit it's parent width.</p>
  
  <p>Thanks in advance</p>
