How to change font and size of buttons and frame in tkinter using python?
提问by Abkb
This is the code that i used to generate a simple text box and a button in tkinter.
这是我用来在 tkinter 中生成一个简单的文本框和一个按钮的代码。
What should be the parameters to have a better look of the frame and buttons?
应该是什么参数才能更好地查看框架和按钮？
root = Tk.Tk()
def submit():
query = entry.get()
retrieve(query)
entry = Tk.Entry(root)
entry.pack()
button = Tk.Button(root, text='submit', command=submit)
button.pack()
root.mainloop()

UPDATE: The New Mexico Tech tkinter website has been archived on GitHub.
更新：新墨西哥科技 tkinter 网站已在 GitHub 上存档。
First the best reference for Tkinter is this New Mexico Tech website. In the toc you will find a section on fonts, and in the section on Button widgetsyou'll find the option font.
首先，Tkinter 的最佳参考是这个 New Mexico Tech 网站。在目录中，您会找到有关 fonts的部分，在有关 Button 小部件的部分中，您会找到选项font。
you must have a Tkinter object to create a font
你必须有一个 Tkinter 对象来创建字体
Python-2
Python-2
Support for Python-2 has officially ended as of Jan 1, 2020
自 2020 年 1 月 1 日起，对 Python-2 的支持已正式结束
from Tkinter import * # Note: UPPER case "T" in Tkinter
import tkFont
root = Tk()
Python-3
Python-3
Python-3 Tk wrappers differ from Python-2
from tkinter import * # Note: lower case "t" in tkinter
from tkinter import font as tkFont # for convenience
root = Tk()
create a font like the example from New Mexico Tech website
创建类似于 New Mexico Tech 网站示例的字体
helv36 = tkFont.Font(family='Helvetica', size=36, weight='bold')
# you don't have to use Helvetica or bold, this is just an example
(Note: recall for Python-3 fontwas imported as tkFontfor convenience)
（注意：为方便起见font，导入了 Python-3 的召回tkFont）
now you can set the font for buttoncreated from Buttonin the original post
现在您可以设置button从Button原始帖子中创建的字体
button['font'] = helv36
The size of the button will depend on your geometry manager, EG: gridor pack. Only the gridmethod is covered in the layouts sectionby New Mexico Tech site, but effbot.orgis also a great reference and he covers packpretty well.
按钮的大小取决于您的几何管理器 EG:grid或pack。New Mexico Tech 站点grid的布局部分仅介绍了该方法，但effbot.org也是一个很好的参考，他的介绍pack非常好。
try: # Python-2
from Tkinter import *
import tkFont
except ImportError: # Python-3
from tkinter import *
from tkinter import font as tkFont
# using grid
# +------+-------------+
# | btn1 | btn2 |
# +------+------+------+
# | btn3 | btn3 | btn4 |
# +-------------+------+
root = Tk()
# tkFont.BOLD == 'bold'
helv36 = tkFont.Font(family='Helvetica', size=36, weight=tkFont.BOLD)
btn1 = Button(text='btn1', font=helv36)
btn2 = Button(text='btn2', font=helv36)
btn3 = Button(text='btn3', font=helv36)
btn4 = Button(text='btn4', font=helv36)
btn5 = Button(text='btn5', font=helv36)
root.rowconfigure((0,1), weight=1) # make buttons stretch when
root.columnconfigure((0,2), weight=1) # when window is resized
btn1.grid(row=0, column=0, columnspan=1, sticky='EWNS')
btn2.grid(row=0, column=1, columnspan=2, sticky='EWNS')
btn3.grid(row=1, column=0, columnspan=1, sticky='EWNS')
btn4.grid(row=1, column=1, columnspan=1, sticky='EWNS')
btn5.grid(row=1, column=2, columnspan=1, sticky='EWNS')
Also try ttk.
也试试ttk。

tkdocs tutorialrecommends using named fonts and styles if you want to tweak the appearences:
如果您想调整外观，tkdocs 教程建议使用命名字体和样式：
import random
try:
import tkinter as Tk
import tkinter.ttk as ttk
import tkinter.font as font
except ImportError: # Python 2
import Tkinter as Tk
import ttk
import tkFont as font
def change_font_family(query, named_font):
named_font.configure(family=random.choice(font.families()))
root = parent = Tk.Tk()
root.title("Change font demo")
# standard named font (everything that uses it will change)
font.nametofont('TkDefaultFont').configure(size=5) # tiny
# you can use your own font
MyFont = font.Font(weight='bold')
query = Tk.StringVar()
ttk.Entry(parent, textvariable=query, font=MyFont).grid() # set font directly
ttk.Button(parent, text='Change Font Family', style='TButton', # or use style
command=lambda: change_font_family(query, MyFont)).grid()
query.set("The quick brown fox...")
# change font that widgets with 'TButton' style use
root.after(3000, lambda: ttk.Style().configure('TButton', font=MyFont))
# change font size for everything that uses MyFont
root.after(5000, lambda: MyFont.configure(size=48)) # in 5 seconds
root.mainloop()
