title: Unable to Center a Grid Using JavaFX
body: <p>I'm using <em>grid.setAlignment(Pos.CENTER);</em> to center my grid within the JavaFX scene however it doesn't seem to work. The grid always displays in the top left of the scene no matter what position I give it. Can anyone see what I'm doing wrong?</p>
  
  <p>My entire code (minus imports) is as follows:</p>
  
  <pre><code>*public class Main extends Application {
  @Override
  public void start(Stage stage) throws Exception {
  Scene scene = new Scene(new Group(), 450, 250);
  
  Button btn = new Button();
  btn.setText("Run");
  
  
  final ComboBox comboBox = new ComboBox();
  comboBox.getItems().addAll(
  "Phase 1",
  "Phase 2",
  "Phase 3",
  "Phase 4",
  "Phase 5"  
  );
  
  GridPane grid = new GridPane();
  grid.setAlignment(Pos.CENTER);
  grid.setVgap(10);
  grid.setHgap(10);
  grid.setPadding(new Insets(5, 5, 5, 5));
  grid.add(new Label("Select Phase: "), 0, 0);
  grid.add(comboBox, 1, 0);
  grid.add(new Label("Select Data: "), 0, 1);
  grid.add(btn, 0, 2);
  
  Group root = (Group)scene.getRoot();
  root.getChildren().add(grid);
  stage.setScene(scene);
  
  
  stage.show();
  }*
  </code></pre>
  
  <p>Thanks!</p>
