如何使用python更改tkinter中按钮和框架的字体和大小？

这是我用来在tkinter中生成简单文本框和按钮的代码.

什么参数可以更好地了解框架和按钮？

 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()

首先,Tkinter的最佳参考是这个新墨西哥技术网站.在toc中,您将找到有关字体的部分,在Button小部件的部分中,您将找到该选项font.

你必须有一个Tkinter对象来创建一个字体

from Tkinter import *
import tkFont
root = Tk()

创建一个类似新墨西哥技术网站示例的字体

helv36 = tkFont.Font(family='Helvetica', size=36, weight='bold')
# you don't have to use Helvetica or bold, this is just an example

现在您可以设置按钮字体

button['font'] = helv36

按钮的大小取决于几何管理器EG:grid或pack.新墨西哥科技网站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,他的内容pack非常好.

from Tkinter import *
import 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')

Tkinter Button字体

也试试ttk.

如果你想调整外观,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',  , # 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()
