In this article, we will see how we can get the end position of the given paragraph 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. In metal typesetting, a font was a particular size, weight and style of a typeface. Formatted document can contain multiple paragraphs.
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_paragraph_end method with the document object
Syntax : document.get_paragraph_end(pos)
Argument : It takes integer as argument
Return : It returns integer
Below is the implementation
Python3
# importing pyglet moduleimport pygletimport pyglet.window.key# width of windowwidth = 500# height of windowheight = 500# caption i.e title of the windowtitle = "Geeksforneveropen"# creating a windowwindow = pyglet.window.Window(width, height, title)# text text = "Welcome to neveropen Have a nice day"# batch objectbatch = pyglet.graphics.Batch()# creating a formatted documentdocument = pyglet.text.document.FormattedDocument(text)# setting style to the documentdocument.set_style(0, len(document.text), dict(font_name ='Arial', font_size = 16, color =(255, 255, 255, 255)))# creating a incremental text layoutlayout = pyglet.text.layout.IncrementalTextLayout(document, 400, 350, batch = batch)# creating a caretcaret = pyglet.text.caret.Caret(layout, color =(150, 255, 150))# caret to window push handlerswindow.push_handlers(caret)# setting caret stylecaret.set_style(dict(font_name ="Arial"))# on draw event@window.eventdef 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.eventdef on_key_press(symbol, modifier): # key "C" get press if symbol == pyglet.window.key.C: # closing the window # window.close() pass # image for iconimg = image = pyglet.resource.image("logo.png")# setting image as iconwindow.set_icon(img)# getting end position of the paragraph which is at # position 0value = document.get_paragraph_end(0)# printing valueprint("End Position : ", end = " ")print(value)# start running the applicationpyglet.app.run() |
Output :
End Position : 40
