在窗口中居中许多小部件 [tkinter]

Question

我需要将两个按钮居中，我可能需要将更多按钮居中，但我不能居中超过一个按钮，所以我需要帮助......这是代码：from tkinter import *from tkinter.ttk import * import osroot = Tk()root.geometry("325x100")    def click():    pass        def click2():    pass            button = Button(root, text="Button 1", command=click, width=25)button.grid(row=0, column=0)button2 = Button(root, text="Button 2", command=click2, width=25)button2.grid(row=1, column=0)      root.grid_rowconfigure(0, weight=1)root.grid_columnconfigure(0, weight=1)      root.mainloop()

Answer 1

我做了一些测试，这就是我想出的。我使用了 .pack() 方法而不是 .grid() 方法，我还使用了一个框架。我是 Python 的新手，但在这里 :)

from tkinter import *

from tkinter.ttk import *

import os

root = Tk()

root.geometry("325x100")

def click():

    pass

def click2():

    pass

frame = Frame(root)

frame.pack(padx = 20, pady = 12)

button = Button(root, text="Button 1", command=click, width=25)

button.pack()

button2 = Button(root, text="Button 2", command=click2, width=25)

button2.pack()

root.mainloop()

这是它的样子：

Answer 2

不要在第一行增加重量。它迫使它扩张。不过，您可能还想考虑其他事情。您最终可能会在该行上放置其他东西，并且您可能需要那个东西来扩展该行。在当前状态下，这将导致您遇到“第 22 条军规”。您可能需要考虑创建一个框架来容纳所有按钮，并将整个框架放在根部。

立即修复：

from tkinter import *

from tkinter.ttk import * 

import os

root = Tk()

root.geometry("325x100")

    

def click():

    pass

        

def click2():

    pass

            

button = Button(root, text="Button 1", command=click, width=25)

button.grid(row=0, column=0)

button2 = Button(root, text="Button 2", command=click2, width=25)

button2.grid(row=1, column=0)

#this is forcing the top row to expand     

#root.grid_rowconfigure(0, weight=1)   

root.grid_columnconfigure(0, weight=1)

      

root.mainloop() 

可能是更好的方法：

from tkinter import *

from tkinter.ttk import * 

import os

root = Tk()

root.geometry("325x100")

    

def click():

    pass

        

def click2():

    pass

    

#by not defining row and column in grid() 

#~ row will be the next available one and column will be 0

    

button_frame = Frame(root)

button_frame.grid(sticky='nswe')

button_frame.grid_columnconfigure(0, weight=1)

#you only need to store a reference if you intend to change/reference/destroy/forget these

#if they are going to always be a button, as initially defined, a reference is dead weight          

Button(button_frame, text="Button 1", command=click, width=25).grid()

Button(button_frame, text="Button 2", command=click2, width=25).grid()

#now you can use grid_rowconfigure without it destroying your button layout      

root.grid_rowconfigure(0, weight=1)

root.grid_columnconfigure(0, weight=1)

      

root.mainloop()
