在窗口[tkinter]中将许多小部件居中

Question

我需要将两个按钮居中，并且可能需要将多个按钮居中，但是我不能将多个按钮居中，所以我需要帮助...

这是代码：

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)
      
root.grid_rowconfigure(0, weight=1)
root.grid_columnconfigure(0, weight=1)
      
root.mainloop()

Answer 1

我做了一些测试，这是我想出的。我使用了.pack（）方法而不是.grid（）方法，并且我还使用了框架。我是Python的新手，但这里是：）

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

不要在第一行增加权重。它迫使它扩展。不过，您可能需要考虑其他事项。您最终可能会在该行上放置其他内容，并且可能需要该东西来扩展行。在当前状态下，这将为您造成“事故22”。您可能要考虑创建一个框架来容纳所有按钮，然后将整个框架放在根上。

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()

可能是一种更好的方法：

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()
