Kivy:如何更改窗口大小? [英] Kivy: How to change window size?

问题描述

我开始使用 kivy 编写程序，但是我在理解它的方式时遇到了一些问题处理尺寸.

I'm starting to write a program using kivy, but I have some problems understand how it deals with sizes.

例如:

import kivy
kivy.require('1.5.1')

from kivy.app import App
from kivy.uix.button import Button

class MyApp(App):
    def build(self): return Button(text='Some text')

MyApp().run()

上面的程序可以运行，但是会创建一个巨大窗口.尝试设置size=(100, 100)不会更改任何内容.设置size_hint=(None, None)将显示正确大小的按钮，但将其随机放置在 still 大窗口内. 尝试设置MyApp的大小也不会更改任何内容.

The above program works, but it creates a huge window. Trying to set size=(100, 100) does not change anything. Setting size_hint=(None, None) will show a button with the correct size, but it is placed randomly inside a still huge window. Trying to set the size of MyApp does not change anything too.

如何创建与按钮大小相同的窗口? 这应该是一个简单的任务，但是查看文档和示例，我对此一无所获.

How do I create a window with the same size of the button? It should be a simple enough task, but looking at the documentation and example I can't find anything about this.

推荐答案

当前有两种方法:

• 在创建窗口之前:

• Before the window is created:

import kivy
kivy.require('1.9.0')

from kivy.config import Config
Config.set('graphics', 'width', '200')
Config.set('graphics', 'height', '200')

动态创建窗口后:

Dynamically after the Window was created:

from kivy.core.window import Window
Window.size = (300, 100)
