JAVAFX imageview拖放

Question

我有一个Tilepane（源码），它载有我存储在数据库中的图像， 我想拖动我的Tilepane中加载的任何图像并将其拖放到我在FXML场景构建器中提供的某个Imageview（目标）。

left:source , right:Target

我在startDragAndDrop（TransferMode.MOVE）中遇到了麻烦，因为我的源中的图像不是最终的imageview，因为它们是从数据库加载的。

我需要一个如何处理从我的Tilepane（源）中将图像放入JavaFX ImageView（目标）的示例。

感谢和问候， 步骤。

  try {  

        Try2.pstmtGetAlbumPhoto = Try2.getConnection().prepareStatement(RetrievePhoto);
        ResultSet RSphoto = Try2.pstmtGetAlbumPhoto.executeQuery();

        while(RSphoto.next()){      
            imageView = new ImageView();
            imageView.setFitWidth(120);
            imageView.setFitHeight(70);          
            String Path = RSphoto.getString("Path");                   
            System.out.println(Path);    
            BufferedImage images = null;

            try {    
                images = ImageIO.read(new File(Path));                
             } catch (IOException ex) {
                System.out.println("Image failed to load.");
             }
            WritableImage wr = null;
            if (images != null) {
                wr = new WritableImage(images.getWidth(), images.getHeight());
                PixelWriter pw = wr.getPixelWriter();
                for (int x = 0; x < images.getWidth(); x++) 
                {
                    for (int y = 0; y < images.getHeight(); y++) {
                    pw.setArgb(x, y, images.getRGB(x, y));
                    }
                }
            }    
    imageView.setImage(wr); 

    final ImageView currentImage = new ImageView();
    currentImage.setImage(wr);
    currentImage.setId(this.getClass().getSimpleName() + System.currentTimeMillis());


    imageView.setOnDragDetected(new EventHandler<MouseEvent>() {
    public void handle(MouseEvent event) {

    Dragboard db = currentImage.startDragAndDrop(TransferMode.ANY);
    ClipboardContent content = new ClipboardContent();
    content.putImage(currentImage.getImage());
    content.putString(getName());
    db.setContent(content);
    event.consume();
    }
    });  

    target.setOnDragOver(new EventHandler<DragEvent>() {
    public void handle(DragEvent event) {
    Dragboard db = event.getDragboard();
    if (db.hasImage() || db.hasFiles()) {
            event.acceptTransferModes(TransferMode.COPY);
        }  
    }
    });    

    target.setOnDragDropped(new EventHandler<DragEvent>() {
        public void handle(DragEvent event) {
            Dragboard db = event.getDragboard();
        if (db.hasImage()) {
            target.setImage(db.getImage());
            String x = db.getString();
            System.out.println(x);
            ;
            event.setDropCompleted(true);
        } 

    }
    });

    TilePane3.getChildren().addAll(imageView);  
    }      
    } catch (SQLException ex) {
        Logger.getLogger(FXMLDocumentController.class.getName()).log(Level.SEVERE, null, ex);
   }
