PYGLET – Flipping Window Buffer
In this article we will see how we can flip the window buffer 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). Flipping means to swap the OpenGL front and back buffers. Flipping method on a double-buffered window to update the visible display with the back buffer. The contents of the back buffer is undefined after this operation. Windows are double-buffered by default. Flipping is called automatically by EventLoop after the on_draw() event.
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 flip method with the window object
Syntax : window.flip()
Argument : It takes no argument
Return : It returns None
Below is the implementation
Python3
import pyglet
import pyglet.window.key
width = 500
height = 500
title = "Geeksforgeeks"
window = pyglet.window.Window(width, height, title)
text = "GeeksforGeeks"
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' )
@window .event
def on_draw():
window.clear()
label.draw()
@window .event
def on_key_press(symbol, modifier):
if symbol = = pyglet.window.key.F:
window.flip()
pyglet.app.run()
|
Output :
Window get flipped when key “F” get pressed, it basically refresh the screen
