PYGLET – On Mouse Release Event

In this article, we will see how we can trigger on mouse release 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 mouse button was released unlike mouse press event which get called when mouse button is pressed.

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 mouse release event, this method get called when this event is triggered 

@window.event       
def on_mouse_release(x, y, button, modifiers):
    print("Mouse button release")

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')

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 mouse release event
@window.event
def on_mouse_release(x, y, button, modifiers):

    # printing some message
    print("Mouse button released")




# 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 :

Mouse button released
Mouse button released
Mouse button released
Mouse button released
