Question

我在使用Scatter（FloatView）的边界框功能时遇到了一些问题。我的构建代码是;

MapPopup = Popup(title='Map')
def openMap(self):
    box = BoxLayout(orientation='vertical')
    stack = StackLayout(orientation='tb-lr', padding=0, spacing=1)
    grid = GridLayout(orientation='vertical', cols=1)
    button = Button(markup=True,bold=True,text='B\nA\nC\nK',width=40,size_hint_x=None)
    button.bind(on_press=partial(self.backButton))
    stack.add_widget(button)
    source = os.path.join(os.getcwd(), 'Games', str(CURRENT_GAME[0]), 'map.png')
    if os.path.isfile(source):
        img = PILImage.open(source)
        width, height = img.size
        scatter = Scatter(size_hint=(None, None), size=(width,height), auto_bring_to_front=False, bbox=((10,10),(10,10)))
        image = Image(source=source, size=(width,height))
        scatter.add_widget(image)
        grid.add_widget(scatter)
    else:
        label = Label(text="Please Start/Load a Game")
        grid.add_widget(label)
    stack.add_widget(grid)
    box.add_widget(stack)
    Container.MapPopup.content = box
    Container.MapPopup.open()

我在bbox=((?,?),(?,?))放入的值无关紧要我收到了错误;

TypeError: 'NoneType' object is not callable

删除bbox并且一切正常，但我正在容纳的图像溢出弹出框。我不想使用scale=调整图片大小。

来自文档：

bbox Added in 1.0.0
Bounding box of the widget in parent space:
 ((x, y), (w, h))

我认为我的问题是它是scatter.scatter.bbox而不是scatter.bbox，因为ScatterLayout实现了FloatLayout，Scatter实现了ScatterLayout，或类似的东西 - 任何人都可以帮助？

非常感谢！
