如何在 .kv 文件中垂直显示 kivy 面板？

Question

我有我的 kivy 文件和我的 python 文件。 我可以显示我的面板并在单击时显示它们的内容，但面板是水平方向的。 我希望这些选项卡垂直显示。 我试过使用

orientation: "vertical" 

这不是我检查过的重复问题，但从未真正找到答案。 这是代码：

    <SampBoxLayout>:
orientation: "vertical"
padding: 10
spacing: 10


BoxLayout:
    orientation: "vertical"
    height: 30

    BoxLayout:
        orientation: "vertical"
        size_hint_x: .25
        size_hint_y: .25

        TabbedPanel:
            do_default_tab: False
            size: 5, 5

            TabbedPanelItem:
                text: "Home"
                Label:
                    text: "Content of Home"
            TabbedPanelItem:
                text: "Browse"
                Label:
                    text: "Content of Browse"
            TabbedPanelItem:
                text: "Radio"
                Label:
                    text: "Content of Radio"
            TabbedPanelItem:
                text: "Made for You"
                Label:
                    text: "Content of Made For You"
            TabbedPanelItem:
                text: "Recently Played"
                Label:
                    text: "Content of Recently Played"
            TabbedPanelItem:
                text: "Favorite Songs"
                Label:
                    text: "Content of Recent Songs"
            TabbedPanelItem:
                text: "Albums"
                Label:
                    text: "Content of Albums"
            TabbedPanelItem:
                text: "Artists"
                Label:
                    text: "Content of Artists"
            TabbedPanelItem:
                text: "Stations"
                Label:
                    text: "Content of Stations"
            TabbedPanelItem:
                text: "Local Files"
                Label:
                    text: "Content of Local Files"
            TabbedPanelItem:
                text: "Videos"
                Label:
                    text: "Content of Videos"
            TabbedPanelItem:
                text: "Videos"
                Label:
                    text: "Content of Videos"
            TabbedPanelItem:
                text: "Podcasts"
                Label:
                    text: "Content of Podc

Answer 1

如果我明白您想要什么，您需要将tab_pos属性添加到您的TabbedPanel ，例如：

    TabbedPanel:
        do_default_tab: False
        tab_pos: 'left_top'

除非您对它们进行其他操作，否则您不需要所有这些BoxLayout项目。
