Question

我在我的kivy应用中使用弹出窗口作为暂停菜单。但我无法弄清楚如何用它来改变屏幕。我尝试过root.manager.current，但由于我的弹出窗口小部件不是屏幕，因此无效。我也尝试使用self.manager.current在python中创建一个函数但是唉也没用。这是我现在能想到的唯一想法，但它也不起作用。任何和所有的帮助表示赞赏。

python代码段

class PausePopup(Popup):
    pass

class MahScreenManager(ScreenManager):
    pass

class MahMenu(Screen):
    pass

class MahGame(Screen):

class MahGameApp(App):
    def build(self):
        window_color = get_color_from_hex("#eaeaea")
        Window.clearcolor = window_color
        return MahScreenManager()

MahGameApp().run()

KV

<MahScreenManager>:
    MahMenu:
        name: "menu"
        id: menu
    MahGame:
        name: "game"
        id: game 

<PausePopup>:
    title: "Gahme is paused"
    size_hint: .5, .7
    BoxLayout:
        orientation: "vertical"
        padding: 10
        spacing: 10
        Button:
            text: "Continue"
            on_release: root.dismiss()

        Button:
            text: "Settings"
            on_release: app.open_settings()
        Button:
            text: "Main Menu"
            on_release: Factory.MahGame().current = "menu"

<MahMenu>:
    BoxLayout:
        padding: 50
        spacing: 25
        orientation: "vertical"
        Button:
            text: "Start Mah Gahme"
            on_release:
                root.manager.transition.direction = "left"
                root.manager.current = "game"
        Button:
            text: "Quit"
            on_release: app.stop()

<MahGame>:
    Button:
        text: "Pause"
        size_hint: 0.1, 0.1
        on_release: Factory.PausePopup().open()

如果您在App课程中有屏幕管理员，可以这样做：

app.sm.current = "menu"

然后在你的App类中，这样做：

    self.sm = MahScreenManager()
    return self.sm
