Prerequisites: Tkinter
Tkinter provides a variety of fonts for different things i.e Heading, Caption, Text, Menu, etc. But the good thing is we can override these fonts using tkinter.font module.
Some fonts provided by the Tkinter are:
- TkDefaultFont
- TkMenuFont
- TkFixedFont
- TkSmallCaptionFont and so on.
In this article, we are going to change the default font. In order to do this, we need to override/ change the configuration of TkDefaultFont. Changing/ overriding the default font is very easy and can be done in the listed way:
- Create the font object using font.nametofont method.
- Use the configure method on the font object
- Then change font style such as font-family, font-size, and so on.
Given below is the proper approach for doing the same.
Approach
- Import module
- Create window
- Create the font object using font.nametofont method.
- Use the configure method on the font object
- Then change font style such as font-family, font-size, and so on.
- Add required elements
- Execute code
Program:
# Import tkinter.Tk and widgets from tkinter import Tk, font
from tkinter.ttk import Button, Label
class App:
def __init__( self , master: Tk) - > None :
self .master = master
# Creating a Font object of "TkDefaultFont"
self .defaultFont = font.nametofont( "TkDefaultFont" )
# Overriding default-font with custom settings
# i.e changing font-family, size and weight
self .defaultFont.configure(family = "Segoe Script" ,
size = 19 ,
weight = font.BOLD)
# Label widget
self .label = Label( self .master, text = "I'm Label" )
self .label.pack()
# Button widget
self .btn = Button( self .master, text = "I'm Button" )
self .btn.pack()
if __name__ = = "__main__" :
# Top level widget
root = Tk()
# Setting window dimensions
root.geometry( "300x150" )
# Setting app title
root.title( "Changing Default Font" )
print (font.names())
app = App(root)
# Mainloop to run application
# infinitely
root.mainloop()
