动态调整大小的数字，因为窗口在JavaFX中调整大小

我有一个任务，我想创建4个内部具有4个三角形的圆圈，以模仿粉丝，创建一个随机更改其每次运行程序的时间的时钟，以及创造一个hang子手的形象。我完成了所有这些数字，但最后一步是在窗口大小调整后，动态调整所创建的所有图形大小。我不确定如何完成这种动态调整大小，但我相信它处理的是我并不真正理解如何实现的绑定。如果有人可以帮助我，将不胜感激。以下是我的代码如下。动态调整大小的数字，因为窗口在JavaFX中调整大小

你可以简单地缩放gridPane到合适的大小，因为你可能会想保留原始宽高比，你可以将它包装在一个StackPane缩放后正确对齐内容：

// keep gridPane at original size 
gridPane.setMinSize(1500, 500); 
gridPane.setMaxSize(1500, 500); 

StackPane root = new StackPane(gridPane); 
// root.setAlignment(Pos.TOP_LEFT); 

// use gridPane size to determine the factor to scale by 
NumberBinding maxScale = Bindings.min(root.widthProperty().divide(1500), 
             root.heightProperty().divide(500)); 
gridPane.scaleXProperty().bind(maxScale); 
gridPane.scaleYProperty().bind(maxScale); 

Scene scene = new Scene(root, 1500, 500);

你只需更换你的下面的代码..

GridPane gridPane = new GridPane(); 
     gridPane.setPadding(new Insets(10)); 
     gridPane.setHgap(5); 
     gridPane.setVgap(5); 
     gridPane.add(gridCircles, 0, 0); 
     gridPane.add(gridClock, 1, 0); 
     gridPane.add(gridHangMan, 2, 0); 

     Scene scene = new Scene(gridPane, 1500, 500); 
     primoStage.setTitle("Assignment 6 Test"); 
     primoStage.setScene(scene); 
     primoStage.show();

与

ScalableContentPane scale = new ScalableContentPane(); 
    GridPane gridPane = new GridPane(); 
    gridPane.setPadding(new Insets(10)); 
    gridPane.setHgap(5); 
    gridPane.setVgap(5); 
    gridPane.add(gridCircles, 0, 0); 
    gridPane.add(gridClock, 1, 0); 
    gridPane.add(gridHangMan, 2, 0); 
    scale.setContent(gridPane); 
    Scene scene = new Scene(scale, 1650, 500); 
    primoStage.setTitle("Assignment 6 Test"); 
    primoStage.setScene(scene); 
    primoStage.show();

使用fololowing库.. https://mvnrepository.com/artifact/eu.mihosoft.jfx.scaledfx/scaledfx/0.3

我不能在JDK中使用本机以外的库作为我的任务。是否有其他可能的方式？ –

然后，您可以使用scaledfx github回购的源代码。 – CTN

@ B.Mack请接受答案，因为它为你工作。 – CTN

我有类似的东西，网页视图当我调整窗口的大小时，它也会调整为

WebView advertising = new WebView(); 
    WebEngine webEngine = advertising.getEngine(); 
    webEngine.load(urlAdvertising); 

    advertising.minHeightProperty().bind(view.widthProperty()); 
    advertising.minWidthProperty().bind(view.widthProperty());

希望它适合你！（;
