How to Use Bitmap images in Button in Tkinter?

Prerequisite: Python GUI – tkinter

Python offers multiple options for developing GUI (Graphical User Interface). Out of all the GUI methods, tkinter is the most commonly used method. It is a standard Python interface to the Tk GUI toolkit shipped with Python.

A bitmap is an array of binary data representing the values of pixels in an image. A GIF is an example of a graphics image file that has a bitmap.

To create a bitmap image ‘bitmap’ attribute of the button() function is used display. It can take the following values:

• error
• gray75
• gray50
• gray25
• gray12
• hourglass
• info
• questhead
• question
• warning

Syntax:

Button(…, bitmap=”<value>”)

Approach 1:

• Import module
• Create object
• Create buttons 
• Execute code

Program:

Python3

# Import Module
from tkinter import *

# Create Objects
root = Tk()

# Buttons
Button(root, relief=RAISED, bitmap="error").pack(pady=10)
Button(root, relief=RAISED, bitmap="hourglass").pack(pady=10)
Button(root, relief=RAISED, bitmap="info").pack(pady=10)
Button(root, relief=RAISED, bitmap="question").pack(pady=10)
Button(root, relief=RAISED, bitmap="warning").pack(pady=10)
Button(root, relief=RAISED, bitmap="gray75").pack(pady=10)
Button(root, relief=RAISED, bitmap="gray50").pack(pady=10)
Button(root, relief=RAISED, bitmap="gray25").pack(pady=10)
Button(root, relief=RAISED, bitmap="gray12").pack(pady=10)
Button(root, relief=RAISED, bitmap="questhead").pack(pady=10)

# Execute Tkinter
root.mainloop()

Output:

Approach 2:

In this method, we will create a list of bitmaps and iterate through all bitmaps while passing them to button() function.

• Import module
• Create object
• Create bitmap list
• Iterate through the list
• Create buttons while iterating
• Execute code

Program:

Python3

# Import Module
from tkinter import *

# Create Objects
root = Tk()

# Create Bitmaps List
bitmaps = ["error",
           "gray75",
           "gray50",
           "gray25",
           "gray12",
           "hourglass",
           "info",
           "questhead",
           "question",
           "warning"]

# Iterate through all bitmap list
for bit in bitmaps:
    Button(root, relief=RAISED, bitmap=bit).pack(pady=10)

# Execute Tkinter
root.mainloop()

Output:
