    Test:


<MainWindow>:
    name: "main"

    GridLayout:
        cols:2


        Button:
            text: "New Order"
            on_release:
                app.root.current = "tabs"
                root.manager.transition.direction = "left"


        Button:
            text: "Basket"
            on_release:
                app.root.current = "second"
                root.manager.transition.direction = "left"


<SecondWindow>:
    name: "second"

    Button:
        text: "Go Back"
        on_release:
            app.root.current = "main"
            root.manager.transition.direction = "right"


<Test>:
    name: "test"
    size_hint: .5,.5
    pos_hint: {'center_x': .5,'center_y': .5}
    do_default_tab: False

    TabbedPanelItem:
        text: 'first tab'
        Label:
            text: 'First tab content area'
    TabbedPanelItem:
        text: 'tab2'
        BoxLayout:
            Label:
                text: 'Second tab content area'
            Button:
                text: 'Button that does nothing'
    TabbedPanelItem:
        text: 'tab3'
        RstDocument:
            text:
                '\\n'.join(("Hello world","-----------","You are in the third tab."))

我想要一个从按下按钮开始的过渡，这会导致选项卡式覆盖，但是屏幕管理器不接受使用选项卡式面板

 kivy.uix.screenmanager.ScreenManagerException: ScreenManager accepts only Screen widget.

怎么才能达到这个效果，我是kivy新手。我想按一个按钮转到另一个正常屏幕，而另一个按钮打开选项卡式屏幕，

解决方法

只需将您的 TabbedPanel 放入 Screen。

美好的一天。使用您的屏幕管理器在每个 screen 之间切换。然后屏幕包含您放置在其中的任何内容的独特布局。这可能包括带有标签的屏幕。
