如何旋转整个kivy application main window？

Question

我构建了一个 kivy 应用程序，专为在纵向触摸屏设备中使用而设计。但是，设备本身（定制的）仅设置为运行个横向应用程序。

我需要将整个应用程序旋转 window 90° 但是当我使用

Window.rotation = 90

我所有的位置提示都被弄乱了，因为实际的宽度和高度被交换了

当我使用

canvas.before:
    PushMatrix
    Rotate:
        angle: 90
        origin: self.center
canvas.after:
    PopMatrix

纵横比似乎是正确的，但我最终 on_press 输入旋转了 90° 并且没有与显示的按钮对齐（即原始正确位置的不可见按钮和可见按钮由于旋转 window.

，现在位于新位置

是否有一个我没有找到的模块可以旋转整个应用程序？

您需要更改 raspberry pi 上的 config.ini 文件。它会在 .kivy 文件夹中。在文件中，您需要找到图形部分，然后在图形部分下找到旋转并将其更改为 90、180 或 270

但我运行遇到触摸不正确翻转的问题，需要在 pi 中进行更改。
