我已经编写了用于拖动任何此类DraggableNode的事件处理程序。

Class DraggableNode extends Node
{
    ...
     onMouseDraggedProperty().set(new EventHandler<MouseEvent>() {
            @Override
            public void handle(MouseEvent event) {
               offsetX = dragStartPoitionX - event.getSceneX();
               offsetY = dragStartPoitionY - event.getSceneY();
               setLayoutX (event.getSceneX());
               setLayoutY (event.getSceneY());
                 ...
            }
     }
 }
