kivy：如何连接Imagebutton？

Question

这是我的代码。我想在按钮中添加 Open_file。

<ImgButton>
    id: open_file
    FloatLayout:
        orientation: "vertical"
        spacing: dp(5)
        ImageButton:
            source:'.\download (1).jfif'
            pos: 50,450
            size_hint : .8,.4
            allow_stretch: False
            keep_ratio: True
            on_press: root.button()

如何连接按钮？

class ImgButton(Screen):
  pass

谁能帮我看看这些代码是怎么做的？
