setFillWidth不起作用JavaFX中

Question

我有這樣的代碼：

public class Minesweeper extends Application { 

private MenuBar menuBar; 
private Stage primaryStage; 
private final VBox vbox = new VBox(8); 
private GridPane gridpane; 

@Override 
public void start(Stage primaryStage) { 

    this.primaryStage=primaryStage; 
    /*createMenu(); 

    //ImageViewPane viewPane = new ImageViewPane(gridpane); 

    vbox.getChildren().addAll(menuBar,gridpane); 
    vbox.setBackground(new Background(fills));*/ 

    HBox hbox = new HBox(50); 
    hbox.setAlignment(Pos.CENTER); // default TOP_LEFT 

    VBox vbox1 = new VBox(); 
    //vbox1.setAlignment(Pos.BOTTOM_CENTER); 
    vbox1.setStyle("-fx-border-style: solid;" 
      + "-fx-border-width: 1;" 
      + "-fx-border-color: black"); 
    vbox1.setPrefSize(300, 300); 
    vbox1.setFillWidth(true); 

    VBox vbox2 = new VBox(10); 
    vbox2.setAlignment(Pos.CENTER); 
    vbox2.setStyle("-fx-border-style: solid;" 
      + "-fx-border-width: 1;" 
      + "-fx-border-color: black"); 

    VBox vbox3 = new VBox(20); 
    vbox3.setAlignment(Pos.TOP_CENTER); 
    vbox3.setStyle("-fx-border-style: solid;" 
      + "-fx-border-width: 1;" 
      + "-fx-border-color: black"); 

    for (int i = 0; i < 5; i++) 
    { 
     Button bt = new Button("Button " + (i+1)); 
     Button bt2 = new Button("Button " + (i+1)); // unfortunately there´s no "clone" or "copy" method 
     Button bt3 = new Button("Button " + (i+1)); 

     vbox1.getChildren().add(bt); 
     vbox2.getChildren().add(bt2); 
     vbox3.getChildren().add(bt3); 
    } 

    hbox.getChildren().addAll(vbox1, vbox2, vbox3); 
    Scene scene = new Scene(hbox, 350, 250); // the hbox is the root node 
    //Scene scene = new Scene(vbox,600,600); 
    primaryStage.setScene(scene); 
    primaryStage.setTitle("Minesweeper"); 
    primaryStage.show(); 

} 

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

，我想在vbox1的按鈕來填充剩餘空間（setfillwidth），但它不工作。也許我沒有正確使用它。

有人可以向我解釋這一點。

感謝

嘗試按鈕maxWidth屬性設置爲無窮大，以允許其採取一切可用的空間。

bt.setMaxWidth(Double.POSITIVE_INFINITY);
