In this article we will see how we can delete caret 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). Caret is basically visible text insertion marker for pyglet.text.layout.IncrementalTextLayout. The caret is drawn as a single vertical bar at the document position on a text layout object. If mark is not None, it gives the unmoving end of the current text selection. Deleting caret means removing the caret from its batch. and disconnecting the caret from further layout events.
We can create a window and caret with the help of commands given below 
 

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

# creating a caret
caret = pyglet.text.caret.Caret(layout, color=(255, 255, 255))

 

In order to create window we use delete method with the caret object
Syntax : caret.delete()
Argument : It takes no argument
Return : It returns None 
 

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"
 
# batch object
batch = pyglet.graphics.Batch()
 
# creating 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, 50, batch = batch)
 
# creating a caret
caret = pyglet.text.caret.Caret(layout, color =(255, 255, 255))
 
# caret to window push handlers
# window.push_handlers(caret)
 
# on draw event
@window.event
def on_draw():
     
    # clear the window
    window.clear()
     
    # draw the batch
    batch.draw()
     
    # 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()
     
 
# image for icon
img = image = pyglet.resource.image("logo.png")
 
# setting image as icon
window.set_icon(img)
 
# 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"
 
# batch object
batch = pyglet.graphics.Batch()
 
# creating 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, 50, batch = batch)
 
# creating a caret
caret = pyglet.text.caret.Caret(layout, color =(255, 255, 255))
 
# caret to window push handlers
window.push_handlers(caret)
 
caret.move_to_point(100, 100)
 
# 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)
 
# deleting caret object
caret.delete()
 
                
# start running the application
pyglet.app.run()
