You have to implement drag on drop on the TreeCell.

Write a CellFactory like this:

TreeView<String> treeView = new TreeView<String>();
    treeView.setCellFactory(new Callback<TreeView<String>, TreeCell<String>>() {
        @Override
        public TreeCell<String> call(TreeView<String> stringTreeView) {
            TreeCell<String> treeCell = new TreeCell<String>() {
                protected void updateItem(String item, boolean empty) {
                    super.updateItem(item, empty);
                    if (item != null) {
                        setText(item);
                    }
                }
            };

            treeCell.setOnDragDetected(new EventHandler<MouseEvent>() {
                @Override
                public void handle(MouseEvent mouseEvent) {

                }
            });

            return treeCell;
        }
    });

Problem

I'm currently working with a JavaFx-2's TreeView representing a file system. I want to enable drag and drop to allow move operations, but it looks like TreeItem doesn't include drag events listeners. I was only able to implement drag and drop on the englobing TreeView object, but it doesn't work for sub-items. Am I missing something, or are drag and drop events not supported for TreeItems yet?
