javafx - 带有 Esri MapView 的 Javafx 应用程序。与 Graphic 交互后将 setOnMouseDragged 返回到 MapView 的问题

Question

我目前正在开发一个利用 Javafx 和 ArcGIS esri 映射功能的应用程序。我遇到的问题是与地图上的图形符号进行交互后，无论是删除还是移动/拖动，应用程序的地图（MapView 场景视图）不再响应鼠标拖动（放大和缩小继续起作用）尽管所有功能起作用，例如删除和移动等。我几乎按照https://developers.arcgis.com/java/sample-code/update-graphics/的示例进行了操作，该示例也表现出相同的行为。关于处理鼠标功能有更好的方法吗？我当前的代码如下。任何建议表示赞赏。

@FXML
void selectSymbol(MouseEvent event) throws InterruptedException, ExecutionException {
    if (event.getButton() == MouseButton.PRIMARY && event.isStillSincePress() && event.getClickCount() == 2) {
        // set the cursor to default
        sceneView.setCursor(Cursor.DEFAULT);

        // clear any selected graphic
        graphicsOverlay.clearSelection();

        // create a point where the user clicked
        mapViewPoint = new Point2D(event.getX(), event.getY());

        // identify graphics on the graphics overlay
        identifyGraphics = sceneView.identifyGraphicsOverlayAsync(graphicsOverlay, mapViewPoint, 10, false);

        identifyGraphics.addDoneListener(() -> {

            try {
                if (!identifyGraphics.get().getGraphics().isEmpty()) {
                    // get the first identified graphic
                    identifiedGraphic = identifyGraphics.get().getGraphics().get(0);
                    // select the identified graphic
                    identifiedGraphic.setSelected(true);

                    sceneView.setOnMouseDragged(e -> {

                            sceneView.setCursor(Cursor.CLOSED_HAND);
