以下代码测试可行

    1. private final TextArea inputTv = new TextArea();
    3. inputTv.setOnDragExited(new EventHandler<DragEvent>() {
    4.     @Override
    5.     public void handle(DragEvent event) {
    6.         List<File> files = event.getDragboard().getFiles();
    7.         if (files!=null&&!files.isEmpty()){
    8.             inputTv.setText(files.get(0).getAbsolutePath());
    9.         }
    10.     }
