PYGLET – Unformatted Document

In this article we will see how we can create a unformatted document 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). Unformatted documents are generally laid out to make copy paste easy without adding structure, such as headings, indentation, font variations. In order words we can say this document contains plain text.

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 pyglet.text.document.UnformattedDocument( method

Syntax : pyglet.text.document.UnformattedDocument(text)

Argument : It takes string as argument



Return : It returns UnformattedDocument object

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 Learn and Grow"
   
# batch object
batch = pyglet.graphics.Batch()
   
# creating a unformatted document
# unlike formatted document it is just plain text
document = pyglet.text.document.UnformattedDocument(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)
   
# creating a caret
caret = pyglet.text.caret.Caret(layout, color =(150, 255, 150))
   
   
   
# 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 == pyglet.window.key.C:
           
        # closing the window
        # window.close()
        pass
      
# image for icon
img = pyglet.resource.image("gfg.png")
  
# setting image as icon
window.set_icon(img)
  
   
# start running the application
pyglet.app.run()
