In this article we will see how we can get the style of the given position in the formatted 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). Formatted documents are generally laid out to enhance their human readability by adding structure, such as headings, indentation, font variations, and other devices that transform plain (unformatted) text so that they have an appearance similar to published works. Style is basically how the the text looks for example color, font or size.
We can create a window and formatted document with the help of commands given below 
 

# creating a window
window = pyglet.window.Window(width, height, title)

# creating document
document = pyglet.text.document.FormattedDocument(text)

 

In order to create window we use get_style(attribute, pos) method with the document object
Syntax : document.get_style(attribute, pos)
Argument : It takes string and integer as argument
Return : It returns object according to the attribute 
 

Below is the implementation 
 

Python3




# 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 = "Welcome to GeeksforGeeks Have a nice day"
 
# batch object
batch = pyglet.graphics.Batch()
 
# creating a formatted 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)
 
# creating a caret
caret = pyglet.text.caret.Caret(layout, color =(150, 255, 150))
 
 
 
# caret to window 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 window 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 = image = pyglet.resource.image("logo.png")
 
# setting image as icon
window.set_icon(img)
 
# getting color at position 10
value = document.get_style("color", 10)
 
# printing value
print("Color at position 10 : ", end = " ")
print(value)
 
 
# start running the application
pyglet.app.run()

Output : 
 

 

Color at position 10 :  (255, 255, 255, 255)
