In this article we will see how we can get the key symbol string for the modifiers 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). Key state handler class is a simple handler that tracks the state of keys on the keyboard. If a key is pressed then this handler holds a True value for it. Symbol string is the symbol of the key which can be recognized by the pyglet module.
We can create a window with the help of command given below
# creating a window window = pyglet.window.Window(width, height, title)
In order to create window we use symbol_string method with the pyglet.window.key
Syntax : key.symbol_string(symbol)
Argument : It takes integer as argument
Return : It returns string
Below is the implementation
Python3
# importing pyglet module import pyglet import pyglet.window.key as key # width of window width = 500 # height of window height = 500 # caption i.e title of the window title = "Geeksforneveropen" # creating a window window = pyglet.window.Window(width, height, title) # text text = "Welcome to neveropen 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) # making layout to display multiline layout.multiline = True # creating a caret caret = pyglet.text.caret.Caret(layout, color = ( 255 , 255 , 255 )) # caret to window 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 window push handlers window.push_handlers(caret) # creating a key state handler key_handler = pyglet.window.key.KeyStateHandler() # key press event @window .event def on_key_press(symbol, modifier): # key "C" get press if symbol = = key.C: # printing the message print ( "Key : C is pressed" ) # image for icon img = image = pyglet.resource.image( "gfg.png" ) # getting symbol string value = key.symbol_string( 121 ) # creating text from the value text = "Symbol string for value 121 : " + str (value) # setting this text to the document document.text = text # setting image as icon window.set_icon(img) # start running the application pyglet.app.run() |
