In this article we will see how we can insert element 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. Inserting something means to add in-between the document by specifying the position.
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 insert_element method with the document object
Syntax : document.insert_element(position, element)
Argument : It takes integer and Element object as 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 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" ))
# inline element element = pyglet.text.document.InlineElement( 10 , 10 , 10 )
# adding element to the document document.insert_element( 1 , element)
# 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) # start running the application pyglet.app.run() |
Output :
