# Changing the Default Font for all the widgets in Tkinter

TkinterPythonGUI-Programming

Let us consider a case where we want to change the default font of a Tkinter application. To apply the font and setting it as the default font for a particular application, we have to use option_add(**options) method where we specify a property such as background color, font, etc. The changes made after defining the method will force all the widgets to inherit the same property.

## Example

In the given script, we have set a default font for the application such that it can be used for all the widgets defined in the application.

#Import the required libraries
from tkinter import *

#Create an instance of Tkinter frame
win = Tk()

win.geometry("700x350")
#Add fonts for all the widgets

#Set the font for the Label widget

# Define the backround color for all the idgets

#Display bunch of widgets
Label(win, text="Label").pack()
Button(win, text="Button").pack()

#Create a Listbox widget
w = Listbox(win)
for i in range(5):
w.insert(i, "item %d" % (i+1))
w.pack()

w = Text(win, width=20, height=10)
w.insert(1.0, "a text widget")
w.pack()

win.mainloop()

## Output

Running the above code will display a window with a Label widget, a Button, a Listbox, and a Text Widget. In the given output, all widgets inherit the same properties.
