In this article we will see how we can trigger window deactivate event 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). This event can be triggered by clicking on another application window. When a window is deactivated it no longer has the keyboard focus.
We can create a window with the help of command given below 
 

pyglet.window.Window(width, height, title)

Below is the syntax of the window on deactivate event, this method get called when this event is triggered 
 

@window.event       
def on_deactivate():
    print("Window Deactivated")

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):
     
    print("nn")
    # key "C" get press
    if symbol == pyglet.window.key.C:
         
        # close the window
        window.close()
 
         
@window.event  
# window deactivate event     
def on_deactivate():
     
    # printing message
    print("Switched to another app")
 
  
 
# image for icon
img = image = pyglet.resource.image("logo.png")
 
# setting image as icon
window.set_icon(img)
                
# start running the application
pyglet.app.run()

Output : 
 

This event is triggered when we switched to another app 
 

Switched to another app
