PYGLET – Setting Window Icon

In this article we will see how we can set the window icon in PYGLET module in python. Pyglet is easy to use but powerful library for developing visually rich GUI applications like games, multimedia etc. A window is a “heavyweight” object occupying operating system resources. Windows may appear as floating regions or can be set to fill an entire screen (fullscreen). An icon is a small graphical representation of a program or file. Icons help users quickly identify the type of file represented by the icon. Icon appear on the left hand side of the title of window.
We can create a window with the help of command given below 

 pyglet.window.Window(width, height, title)

In order to create window we use set_icon method with the window object
Syntax : window.set_icon(img)
Argument : It takes pyglet.image object as argument
Return : It returns None 

Below is the implementation 

Python3

# importing pyglet module
import pyglet
import pyglet.window.key

# width of window
width = 500

# height of window
height = 500

# caption i.e title of the window
title = "Geeksforgeeks"

# creating a window
window = pyglet.window.Window(width, height, title)

# text
text = "GeeksforGeeks"

# creating a label with font = times roman
# font size = 36
# aligning it to the center
label = pyglet.text.Label(text,
                          font_name ='Times New Roman',
                          font_size = 36,
                          x = window.width//2, y = window.height//2,
                          anchor_x ='center', anchor_y ='center')

# on draw event
@window.event
def on_draw():

    # clearing the window
    window.clear()

    # drawing the label on the window
    label.draw()

# key press event
@window.event
def on_key_press(symbol, modifier):

    # key "C" get press
    if symbol == pyglet.window.key.C:

        # close the window
        window.close()

# image for icon
img = image = pyglet.resource.image("logo.png")

# setting image as icon
window.set_icon(img)

# start running the application
pyglet.app.run()

Output :
