Snapshot does not work with (invisible) WebView nodes

    Details

    • Subcomponent:
      web

      Description

      Snapshot only works when pressing on (uncommented) snapshot button. In this case the WebView was rendered on screen before, otherwise the png only shows the test-label.

      private final String INITIAL_TEXT = "<head></head><body><p style=\"text-align: center; font-size:36pt;\"><font face=\"Arial\">emptyText</font></p></body>";

      @Override
      public void start(Stage stage) {
      stage.setTitle("WebView Snapshot Sample");
      stage.setWidth(500);
      stage.setHeight(500);
      Scene scene = new Scene(new Group());

      final VBox root = new VBox();
      root.setPadding(new Insets(8, 8, 8, 8));
      root.setSpacing(5);

      WebView webView = new WebView();
      webView.getEngine().loadContent(INITIAL_TEXT);

      // Button snapshotButton = new Button("Snapshot");
      // snapshotButton.setOnAction(new EventHandler<ActionEvent>() {
      //
      // @Override
      // public void handle(ActionEvent arg0) {
      // createSnapShot(root);
      // }
      // });
      //
      // root.getChildren().addAll(webView, new Label("Test Label"), snapshotButton);
      root.getChildren().addAll(webView, new Label("Test Label"));

      scene.setRoot(root);
      stage.setScene(scene);

      createSnapShot(root);

      stage.show();
      }

      private void createSnapShot(final Node node) {
      Platform.runLater(new Runnable() {

      @Override
      public void run() {
      SnapshotParameters params = new SnapshotParameters();
      Image image = node.snapshot(params, null);
      System.out.println("snapshot image created");

      try {
      ImageIO.write(SwingFXUtils.fromFXImage(image, null), "png", new File("d:\\output.png"));
      } catch (IOException e) {
      e.printStackTrace();
      }

      }
      });
      }

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