PYGLET – Mouse State Handler

  • Last Updated : 22 Sep, 2021

In this article, we will see how we can create a mouse state handler object in the 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). Mouse state handler class is a simple handler that tracks the state of buttons from the mouse. If a button is pressed then this handler holds a True value for it.

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

# creating a window
window = pyglet.window.Window(width, height, title) 

In order to create window we use MouseStateHandler method with pyglet.window.mouse
Syntax : mouse.MouseStateHandler()
Argument : It takes no argument
Return : It returns MouseStateHandler object 
 

Below is the implementation  

Python3






# importing pyglet module
import pyglet
import pyglet.window.key as 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 = "Welcome to GeeksforGeeks Have a nice day"
   
# batch object
batch = pyglet.graphics.Batch()
   
# creating document
document = pyglet.text.document.FormattedDocument(text)
   
# setting style to the document
document.set_style(0, len(document.text), dict(
                         font_name ='Arial', font_size = 16
                         color =(255, 255, 255, 255)))
   
# creating a incremental text layout
layout = pyglet.text.layout.IncrementalTextLayout(
               document, 400, 350, batch = batch)
 
# making layout to display multiline
layout.multiline = True
   
# creating a caret
caret = pyglet.text.caret.Caret(layout, color =(255, 255, 255))
   
# caret to window push handlers
window.push_handlers(caret)
   
# setting caret style
caret.set_style(dict(font_name ="Arial"))
   
   
# on draw event
@window.event
def on_draw():
       
    # clear the window
    window.clear()
       
    # draw the batch
    batch.draw()
       
    # caret to window push handlers
    window.push_handlers(caret)
     
 
       
# key press event    
@window.event
def on_key_press(symbol, modifier):
   
    # key "C" get press
    if symbol == key.C:
         
        # printing the message
        print("Key : C is pressed")
         
# image for icon
img = image = pyglet.resource.image("gfg.png")
 
     
 
# creating a mouse state handler
mouse_handler = pyglet.window.mouse.MouseStateHandler()
 
value = mouse_handler
 
# creating text from the value
text = "Mouse State Handler : " + str(type(value))
 
# setting this text to the document
document.text = text
   
# setting image as icon
window.set_icon(img)
    
# start running the application
pyglet.app.run()
