我需要使绘制的矩形鼠标透明，以便看到桌面。以下代码绘制了我的矩形。我应该添加什么来获得它？感谢帮助

public void start(Stage primaryStage) {
    Group group = new Group();

    Rectangle rect = new Rectangle(20,20,200,200);

    rect.setArcHeight(15);
    rect.setArcWidth(15);

    rect.setStroke(Color.BLACK);
    group.getChildren().add(rect);

    Scene scene = new Scene(group, 300, 200);
    primaryStage.setScene(scene);
    primaryStage.show();
}

使用下面的代码(感谢这里的几个帖子),我画了一个矩形,我想要可调整大小和可移动.两个锚(左上角和右下角)做我想要的,最后一个(中下)移动矩形,但是两个第一个锚不跟随矩形.

当我让它们移动时,它们的监听器会调整矩形的大小.
