PYGLET – Caret
In this article we will see how we can use caret object on the window 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 visible text selection on the layout is updated along with mark and position. By default the layout’s graphics batch is used, so the caret does not need to be drawn explicitly. Even if a different graphics batch is supplied, the caret will be correctly positioned and clipped within the layout.
We can create a window with the help of command given below
pyglet.window.Window(width, height, title)
In order to create window we use pyglet.text.caret.Caret method
Syntax : pyglet.text.caret.Caret(layout, color=(255, 255, 255))
Argument : It takes 2 argument, first is layout and second is the color
Return : It returns Caret object
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 = "w3wiki" # creating a window window = pyglet.window.Window(width, height, title) # text text = "Welcome to w3wiki" # 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) # start running the application pyglet.app.run() |
