Python-Kivy中的窗口大小调整

Kivy是Python中与平台无关的GUI工具。由于可以在Android，IOS，Linux和Windows等操作系统上运行，因此Kivy为您提供了编写代码一次并在不同平台上运行的功能。它基本上用于开发Android应用程序，但这并不意味着它不能在桌面应用程序上使用。

Kivy是该平台，其大小无关紧要，因为它可以进行自我调整，但是如果我们要在某种程度上固定大小（无论是高方向还是宽度方向还是不受边界限制）怎么办取决于用户需求。

示例

# When there is no fix window size i.e fully resizable according to user:

from kivy.config import Config

# 0 being off 1 being on as in true / false you can use 0 or 1 && True or False

Config.set('graphics', 'resizable', True)

# import kivy module

import kivy

# this restrict the kivy version i.e below this kivy version you cannot use the app

kivy.require("1.9.1")

# base Class of your App inherits from the App class. app:always refers to the instance of your #application

from kivy.app import App

# if you not import label and use it through error

from kivy.uix.label import Label

# defining the App class

class MyLabelApp(App):

def build(self):

# label display the text on screen

# markup text with different colour

l2 = Label(text ="[color = ff3333][b]Hello !!!!!!!!!!![/b]

[/color]\n [color = 3333ff]World!!! !!:):):):)[/color]",

font_size ='20sp', markup = True)

return l2

# creating the object

label = MyLabelApp()# run the window

label.run()

# No resizing, fixed size with the width:

from kivy.config import Config

# 0 being off 1 being on as in true / false

# you can use 0 or 1 && True or False

Config.set('graphics', 'resizable', '0')

# fix the width of the window

Config.set('graphics', 'width', '500')

#fixing the height of the window

from kivy.config import Config

# 0 being off 1 being on as in true / false

# you can use 0 or 1 && True or False

Config.set('graphics', 'resizable', '0')

# fix the height of the window

Config.set('graphics', 'height', '400')
