我有这个代码:
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);
}
我希望vbox1中的按钮填充剩余的空间(setfillwidth),但它不起作用。也许我没有正确使用它。
有人能向我解释一下吗?
感谢
尝试将按钮的maxWidth
属性设置为无穷大,以允许它占用所有可用空间。
bt.setMaxWidth(Double.POSITIVE_INFINITY);
