使用剪裁圆忽略JavaFX AnchorPane maxHeight

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;
import javafx.scene.shape.Circle;
import javafx.stage.Stage;

public class Main extends Application {
    @Override
    public void start(Stage primaryStage) {
        AnchorPane anchorPane = new AnchorPane();
        anchorPane.setPrefSize(400, 400);
        anchorPane.setStyle("-fx-background-color: lightgray");

        double maxHeight = 200;

        Circle clipCircle = new Circle();
        clipCircle.setCenterX(anchorPane.getPrefWidth() / 2);
        clipCircle.setCenterY(anchorPane.getPrefHeight() / 2);
        clipCircle.setRadius(maxHeight / 2);

        anchorPane.setClip(clipCircle);

        Scene scene = new Scene(anchorPane);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}
