当用户运行程序时,我需要将场景的组件放置在窗口的中间,事实并非如此。我该如何解决?
该场景似乎只出现在右侧,而不出现在中央。
我附加了我得到的输出图像。
public class WelcomeScene extends Scene{
public WelcomeScene(Pane pane, double width, double height){
super(pane,width,height);
setFill(Color.PINK);
VBox vbox = new VBox();
Label label = new Label("Welcome to the typing\n practice world");
label.setFont(new Font("Cambria", 32));
label.setStyle("-fx-text-alignment: center;");
label.setTextFill(Color.RED);
label.centerShapeProperty().bind(pane.centerShapeProperty());
HBox hbox = new HBox();
Button StartTypingBtn = new Button("Start typing");
Button showFingurePosition = new Button("Check fingures prositions");
Button checkImprovement = new Button("Check Improvement");
hbox.setSpacing(10);
hbox.setAlignment(Pos.CENTER);
hbox.getChildren().add(StartTypingBtn);
hbox.getChildren().add(showFingurePosition);
hbox.getChildren().add(checkImprovement);
vbox.getChildren().addAll(label, new
ImageView("photos/hands_email.gif"),
hbox);
vbox.setAlignment(Pos.CENTER);
pane.getChildren().add(vbox);
pane.setCenterShape(true);
}
}
public class Touch extends Application {
@Override
public void start(Stage primaryStage) throws Exception {
Rectangle2D screenBounds = Screen.getPrimary().getVisualBounds();
primaryStage.setScene(new WelcomeScene(new Pane(),
screenBounds.getWidth(),screenBounds.getHeight()));
primaryStage.show();
}
public static void main(String [] args) {
Application.launch(args);
}
}
enter image description here
最佳答案
您可以做的一件事是将Pane
更改为StackPane
。
触摸
primaryStage.setScene(new WelcomeScene(new StackPane(),
screenBounds.getWidth(), screenBounds.getHeight()));
欢迎光临
public WelcomeScene(StackPane pane, double width, double height)

关于java - 为什么组件没有出现在屏幕中央?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/55950914/
