PYGLET – Closing Window

In this article we will see how we can close 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). We can close the window manually by pressing on the close button of the window although some time there is a need to close a window programmatically.
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 close method with the window object 
Syntax : window.close()
Argument : It takes no 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 "E" get press
    if symbol == pyglet.window.key.E:

        # close the window
        window.close()


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

Output :

This window get closed when key “E” is pressed
