PYGLET – On Move Event

In this article we will see how we can trigger on move 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 get called when the window get moved, we can change the position of the window with the help of set_location method.

We can create a window with the help of command given below 

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

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

@window.event       
def on_move(x, y):
    print("Window Moved")

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')

new_label = pyglet.text.Label(text,
                          font_name ='Times New Roman',
                          font_size = 10,
                          x = 25, y = 25)

# 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:

        print("Key C is pressed")


# on move event
@window.event
def on_move(x, y):

    # printing some message
    print("Window Move")
    print("New Position : ", end = "")
    print(x, y)




# image for icon
img = image = pyglet.resource.image("logo.png")

# setting image as icon
window.set_icon(img)

# moving window
window.set_location(100, 200)

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

Output :

Window Move
New Position : 100 200
