PYGLET – Mouse Button String
  • Last Updated : 23 Sep, 2020

In this article we will see how we can mouse button string 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). 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. Mouse string is a string describing a set of active mouse buttons.

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 buttons_string method with pyglet.window.mouse

Syntax : mouse.buttons_string(buttons)

Argument : It takes integer i.e bitwise combination of mouse button constants as argument



Return : It returns string

Below is the implementation




# 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 winow 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 winow 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: 
          
        # printng the message
        print("Key : C is pressed")
          
# image for icon 
img = image = pyglet.resource.image("gfg.png"
  
      
  
# getting mouse button string
value = pyglet.window.mouse.buttons_string(2 | 5)
  
# creating text from the value
text = "Mouse Button String  : " + str(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()
