PYGLET – Clearing Window

In this article we will see how we can clear a window 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). Clearing window is a convenience method for clearing the color and depth buffer, in other words clearing removes all the elements drawn on the 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 clear method with the window object 
Syntax : window.clear()
Argument : It takes no argument
Return : It returns None 

Below is the implementation 

Python3

# importing pyglet module
import pyglet

# 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():

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

    # clearing the window
    window.clear()



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

Output :
