PYGLET – Drawing Rectangle
In this article we will see how we can draw rectangle on 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). A rectangle is a four-sided shape where every angle is a right angle (90°). Also opposite sides are parallel and of equal length. Rectangle is drawn with the help of shapes module in pyglet.
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 Rectangle method with pyglet.shapes
Syntax : shapes.Rectangle(x, y, width, height, color=(255, 255, 255), batch=None)
Argument : It takes position i.e pair of integer, width and height of rectangle, color of rectangle and last is batch object
Return : It returns Line object
Below is the implementation
Python3
# importing pyglet module import pyglet # importing shapes from the pyglet from pyglet import shapes # width of window width = 500 # height of window height = 500 # caption i.e title of the window title = "w3wiki" # creating a window window = pyglet.window.Window(width, height, title) # creating a batch object batch = pyglet.graphics.Batch() # properties of rectangle # co-ordinates of rectangle co_x = 150 co_y = 150 # width of rectangle width = 300 # height of rectangle height = 200 # color = green color = ( 50 , 225 , 30 ) # creating a rectangle rec1 = shapes.Rectangle(co_x, co_y, width, height, color = color, batch = batch) # changing opacity of the rect1 # opacity is visibility (0 = invisible, 255 means visible) rec1.opacity = 250 # creating another rectangle with properties # x, y co ordinate : 50, 250 # width, height of rectangle : 300, 200 # color = red color = ( 255 , 25 , 25 ) # creating rectangle rec2 = shapes.Rectangle( 50 , 250 , 300 , 200 , color = color, batch = batch) # changing opacity of the rec2 # opacity is visibility (0 = invisible, 255 means visible) rec2.opacity = 100 # window draw event to draw rectangles @window .event def on_draw(): # clear the window window.clear() # draw the batch batch.draw() # run the pyglet application pyglet.app.run() |
