强制将Kivy小部件的方向设置为横向/纵向 [英] Forcing a Kivy widget's orientation to be landscape/portrait

问题描述

我正在开发一个我希望ScreenManager的屏幕之一横向放置的应用程序.我不希望它本身变成垂直.到目前为止，我了解到的只有buildozer.spec文件可以更改应用程序的方向.我想要的是更改小部件的方向.有什么办法吗?

I'm developing an app where I want one of ScreenManager's screen to be in landscape orientation. I don't want it to change to vertical by itself. As of now, what I learned is only buildozer.spec file can change the app's orientation. What I want is to change the widget's orientation. Is there any way to do this?

推荐答案

您可以将屏幕内容放在分散的布局上，然后旋转它:

You can place a content of the screen on a scatter layout, and then rotate it:

test.kv:

ScreenManager:

    Screen:
        name: 'normal'

        Grid

    Screen:
        name: 'flipped'

        ScatterLayout:
            do_rotation: False
            do_scale: False
            do_translation: False
            rotation: 90
            pos_hint: {'center_x': 0.5, 'center_y': 0.5}
            size_hint: None, None
            size: root.height, root.width

            Grid


<Grid@GridLayout>:
    cols: 1

    Button:
        text: 'normal'
        on_press: app.root.current = 'normal'
    Button:
        text: 'flipped'
        on_press: app.root.current = 'flipped'

main.py:

#!/usr/bin/env python2
# -*- coding: utf-8 -*-
from kivy.app import App


class Test(App):
    pass


Test().run()
