PYGLET – Activating Window
  • Last Updated : 22 Sep, 2020

In this article we will see how we can activate 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). Activating window means a attempt to restore keyboard focus to the window. Depending on the window manager or operating system, this may not be successful. For example, on Windows XP an application is not allowed to “steal” focus from another application.

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 activate method with the window object
Syntax : window.activate()

Argument : It takes no argument

Return : It returns None



Below is the implementation




# 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 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')
  
# drawing label
@window.event
def on_draw():
    window.clear()
    label.draw()
  
# try to restore keyboard focus to the window
window.activate()
  
  
# start running the application
pyglet.app.run()
