GridPane留中心，而调整窗口的大小

Question

目前我gridpane撑集中在X轴上，而调整窗口的大小，我怎样才能得到它留在Y轴为中心呢？

我有这样的一个TabPane标签：

GridPane grid = new GridPane(); 
    grid.setPadding(new Insets(20, 0, 0, 0)); 
    grid.setAlignment(Pos.CENTER); 
    grid.setHgap(20); 
    grid.setVgap(20); 

    this.setContent(grid);

这里的关键是VBox.setVgrow(tabPane, Priority.ALWAYS);

import javafx.application.Application; 
import javafx.scene.Scene; 
import javafx.scene.control.MenuBar; 
import javafx.scene.control.TabPane; 
import javafx.scene.layout.Priority; 
import javafx.scene.layout.VBox; 
import javafx.stage.Stage; 

/** 
* 
* @author blj0011 
*/ 
public class JavaFXApplication65 extends Application 
{ 

    @Override 
    public void start(Stage primaryStage) 
    { 
     VBox root = new VBox(); 
     MenuBar mb = new MenuBar(); 

     TabPane tabPane = new TabPane(); 
     root.getChildren().addAll(mb, tabPane); 


     //StackPane stackPane = new StackPane(); 
     CreateProfilePane cp = new CreateProfilePane(); 
     tabPane.getTabs().add(cp); 
     VBox.setVgrow(tabPane, Priority.ALWAYS); 



     Scene scene = new Scene(root, 300, 250); 

     primaryStage.setTitle("Hello World!"); 
     primaryStage.setScene(scene); 
     primaryStage.show(); 
    } 

    /** 
    * @param args the command line arguments 
    */ 
    public static void main(String[] args) 
    { 
     launch(args); 
    } 

}
