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
# 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() |
Output :
