How To Define Custom Fonts – Python Tkinter GUI Tutorial #151

In this video I’ll show you how to define custom fonts for your tkinter app.

Setting custom fonts is incredibly useful because you can update all the fonts for all the widgets in your app with one quick change.

All we have to do is import Font from tkinter.font and we can define custom fonts to use in all the widgets of our app.

Python Code: fonts.py
(Github Code)

from tkinter import *
from tkinter.font import Font

root = Tk()
root.title('Codemy.com - Custom Fonts')
root.iconbitmap('c:/gui/codemy.ico')
root.geometry("500x500")

# Define Our Font
bigFont = Font(
	family="Times",
	size=40,
	weight="bold",
	slant="roman",
	underline=0,
	overstrike=0)

# Define Our Font
mediumFont = Font(
	family="Helvetica",
	size=24,
	weight="normal",
	slant="italic",
	underline=1,
	overstrike=0)

# Define A Button
my_button1 = Button(root, text="Big Text", font=bigFont)
my_button1.pack(pady=20)


# Label
my_label = Label(root, text="more big text", font=mediumFont)
my_label.pack(pady=20)

root.mainloop()
