JavaFX TreeView - 如果相同的TreeCell位于两个TreeView中，则为Listener

Question

如果treeview2中存在树状单元，是否有可能添加一个更改treeview1中树状图形图形的侦听器？如果它被删除，也删除图形？

现在我的代码的简化MCVE，带有一个从一个treeView到另一个树视图添加treeItem的按钮：

        Button button2 = new Button("qq");
    final CategoryAxis xAxis = new CategoryAxis();
    final NumberAxis yAxis = new NumberAxis();

    TreeItem<String> treeRoot = new TreeItem<String>("Root Node");
    treeRoot.setExpanded(true);
    treeRoot.getChildren().addAll(
            new TreeItem<String>("Item 1"),
            new TreeItem<String>("Item 2"),
            new TreeItem<String>("Item 3")
    );
    TreeView<String> treeView = new TreeView<String>(treeRoot);

    TreeItem<String> treeRoot2 = new TreeItem<String>("Root Node2");
    treeRoot2.setExpanded(true);
    treeRoot2.getChildren().addAll(
            new TreeItem<String>("Item 1"),
            new TreeItem<String>("Item 2"),
            new TreeItem<String>("Item 3")
    );
    TreeView<String> treeView2 = new TreeView<String>(treeRoot2);

    button2.setOnAction(new EventHandler<ActionEvent>() {
        @Override
        public void handle(ActionEvent e) {
            treeRoot.getChildren().add(treeRoot2.getChildren().get(1));
        }
    });

    StackPane root = new StackPane();
    SplitPane splitPane = new SplitPane();
    splitPane.getItems().addAll(treeView, treeView2);
    root.getChildren().addAll(splitPane);
    root.getChildren().add(button2);
    Scene scene = new Scene(root, 1000, 1000);

    primaryStage.setTitle("Hello World!");
    primaryStage.setScene(scene);
    primaryStage.show();
