Question

我正在使用两个彼此重叠的SubScenes实现一个应用程序。第一个以3d形式保存节点，第二个ui组件（2d形状）。 Ui工作正常，但是例如使用“ setOnMouseClicked”时，无法到达3d子场景中的节点。

我的代码如下例：

public class Main extends Application {

@Override
public void start(Stage primaryStage) throws Exception {

    final double width = 500.0;
    final double height = 500.0;

    // init scene
    Group root = new Group();
    Scene scene = new Scene(root, width, height);
    scene.setFill(Color.BLACK);

    root.setOnMouseClicked(clicked -> System.out.println("I'm root!"));
    scene.setOnMouseClicked(clicked -> System.out.println("I'm scene!"));

    // init sub scene 'red'
    AnchorPane redRoot = new AnchorPane();
    SubScene red = new SubScene(redRoot, width, height);
    Rectangle redRec = new Rectangle(100, 100, Color.RED);
    AnchorPane.setTopAnchor(redRec, 100.0);
    AnchorPane.setLeftAnchor(redRec, 100.0);
    redRoot.getChildren().add(redRec);

    red.setOnMouseClicked(clicked -> System.out.println("I'm red!"));
    redRoot.setOnMouseClicked(clicked -> System.out.println("I'm red root!"));
    redRec.setOnMouseClicked(clicked -> System.out.println("I'm red rec!"));

    // init sub scene 'blue'
    AnchorPane blueRoot = new AnchorPane();
    SubScene blue = new SubScene(blueRoot, width, height);
    Rectangle blueRec = new Rectangle(100, 100, Color.BLUE);
    AnchorPane.setBottomAnchor(blueRec, 100.0);
    AnchorPane.setRightAnchor(blueRec, 100.0);
    blueRoot.getChildren().add(blueRec);

    blue.setOnMouseClicked(clicked -> System.out.println("I'm blue!"));
    blueRoot.setOnMouseClicked(clicked -> System.out.println("I'm blue root!"));
    blueRec.setOnMouseClicked(clicked -> System.out.println("I'm blue rec!"));

    // add sub scenes
    root.getChildren().addAll(red, blue);
    //root.getChildren().addAll(blue, red);

    // init stage
    primaryStage.setScene(scene);
    primaryStage.setTitle("Subscene test");
    primaryStage.show();
}

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

运行此示例并单击红色矩形输出：

I'm blue root!
I'm blue!
I'm root!
I'm scene!

单击蓝色将输出预期的结果：

I'm blue rec!
I'm blue root!
I'm blue!
I'm root!
I'm scene!

为什么事件分发链没有到达红色矩形？

感谢您的帮助！
