Python3.x 如何将 tkinter 窗口设置为恒定大小

通过设置pack_propagate(0)可以关闭pack_propagate

在这里关闭pack_propagate基本上是说不要让框架内的小部件控制它的大小.所以你把它的宽度和高度设置为500.关闭propagate stills可使其达到此大小，而无需小部件更改框架的大小以填充其各自的宽度/高度，这是正常情况下会发生的情况

要关闭调整根窗口大小，可以设置root.resizable(0, 0)，其中x和y方向分别允许调整大小.

要将maxsize设置为window，如另一个答案中所述，您可以设置maxsize属性或minsize，尽管您可以只设置根窗口的几何图形，然后关闭调整大小.更灵活一点.

当你在小部件上设置grid或pack时，它将返回None.所以，如果你想保持对小部件对象的引用，你不应该在小部件上设置变量，在这个小部件上调用grid或pack.您应该将变量设置为小部件Widget(master, ....)，然后在小部件上调用pack或grid.

import tkinter as tk

def startgame():

    pass

mw = tk.Tk()

#If you have a large number of widgets, like it looks like you will for your
#game you can specify the attributes for all widgets simply like this.
mw.option_add("*Button.Background", "black")
mw.option_add("*Button.Foreground", "red")

mw.title('The game')
#You can set the geometry attribute to change the root windows size
mw.geometry("500x500") #You want the size of the app to be 500x500
mw.resizable(0, 0) #Don't allow resizing in the x or y direction

back = tk.Frame(master=mw,bg='black')
back.pack_propagate(0) #Don't allow the widgets inside to determine the frame's width / height
back.pack(fill=tk.BOTH, expand=1) #Expand the frame to fill the root window

#Changed variables so you don't have these set to None from .pack()
go = tk.Button(master=back, text='Start Game', command=startgame)
go.pack()
close = tk.Button(master=back, text='Quit', command=mw.destroy)
close.pack()
info = tk.Label(master=back, text='Made by me!', bg='red', fg='black')
info.pack()

mw.mainloop()
