PYGLET – Setting Maximum Window Size

0 0 1 minute read

In this article we will see how we can set the maximum window size 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). Once maximum size is set, the user will not be able to resize the window larger than the given dimensions. There is no way to remove the maximum size constraint on a window (but you could set it to a large value). The behaviour is undefined if the maximum size is set smaller than the current size of 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 set_maximum_size method with the window object
Syntax : window.set_maximum_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 = "Geeksforzambiatek"
 
# creating a window
window = pyglet.window.Window(width, height, title)
 
# text 
text = "zambiatek"
 
# 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 maximum size of the window
window.set_maximum_size(700, 700)
 
# maximize the size of the window
window.maximize()
                
# start running the application
pyglet.app.run()
