PYGLET – Setting Exclusive Mouse for Window
  • Last Updated : 22 Sep, 2020

In this article we will see how we can set exclusive mouse for the window 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). Exclusive mouse hide the mouse cursor and direct all mouse events to this window. When enabled, this feature prevents the mouse leaving the window. It is useful for certain styles of games that require complete control of the mouse. The position of the mouse as reported in subsequent events is meaningless when exclusive mouse is enabled; you should only use the relative motion parameters dx and dy.

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

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

In order to create window we use set_exclusive_mouse method with the window object

Syntax : window.set_exclusive_mouse(True)

Argument : It takes bool as argument



Return : It returns None

Below is the implementation




# 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')
  
# 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:
          
        # close the window
        window.close()
  
  
# setting excluive mouse
window.set_exclusive_mouse(True)
                
# start running the application
pyglet.app.run()
