如何在Javafx中翻译滚动窗格的内容？

ScrollPane scrollPane = new ScrollPane();

VBox contentPane = new VBox();

scrollPane.setContent(contentPane);

Button translateButton = new Button("Translate");

translateButton.setOnAction(event -> {
    // 执行翻译操作
});

for (Node node : contentPane.getChildren()) {
    if (node instanceof Text) {
        Text textNode = (Text) node;
        String translatedText = translate(textNode.getText()); // 调用翻译API获取翻译后的文本
        textNode.setText(translatedText);
    }
}

Scene scene = new Scene(new VBox(scrollPane, translateButton), 400, 300);
primaryStage.setScene(scene);
primaryStage.show();
