Threepenny - GUI:拖放 - 访问 DragData
Threepenny-GUI: Drag'n'Drop - Access DragData
我目前正在努力在调用 on UI.drop
时访问被拖动元素的 DragData
。我有这样的东西:
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?
有人可以帮助我吗?提前致谢!
您好,

我知道了:
on UI.drop field $ \dragData -> do
d <- read dragData
也许对其他人有帮助 ;)
