Threepenny-GUI：拖放 - 访问DragData

Question

我目前在获取拖动元素的DragData时遇到了困难，当调用on UI.drop时。我有如下代码:

tile <- UI.new
    # set UI.draggable True
    # set UI.dragData (show player)

field <- UI.new
    # set UI.droppable True

on UI.drop field $ \_ -> do
    -- How to receive the DragData here?

有人能帮我吗？先谢谢了！

问候， Moritz

我明白了：

on UI.drop field $ \dragData -> do
    d <- read dragData

也许对其他人有所帮助；)
