PYGLET – Caret Visibility Property
  • Last Updated : 23 Sep, 2020

In this article we will see how we can access visible property of the 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. The caret may be hidden despite this property due to the periodic blinking or by on_deactivate if the event handler is attached to a window.

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 visible attribute with the caret object

Syntax : caret.visible

Argument : It takes no argument



Return : It returns bool

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 = "Welcome to GeeksforGeeks Have a nice day"
  
# 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, 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 = image = pyglet.resource.image("logo.png")
  
# setting image as icon
window.set_icon(img)
  
  
# getting caret visible property
value = caret.visible
  
# priting the value
print("Caret Visible  : ", end ="")
print(value)
  
  
  
# start running the application
pyglet.app.run()

Output :

Output :

Caret Visible  : True
