PYGLET – Setting Size / Resizing of Window
  • Last Updated : 03 Jun, 2021

In this article we will see how we can set the size of the 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 set the size of the window while creating a window, although sometime there is a need to resize the window programmatically. The behaviour is undefined if the window is not resizable, or if it is currently fullscreen. The window size does not include the border or title bar.
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_size method with the window object
Syntax : window.set_size(width, height)
Argument : It takes two integer 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 centre
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)
 
# setting window size
# resizing the window
window.set_size(300, 400)
 
 
# hiding mouse
window.set_mouse_visible(False)
                
# start running the application
pyglet.app.run()

Output :
