PYGLET – On Text Event
In this article we will see how we can trigger on text event 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).Typically this is called after on_key_press() and before on_key_release(), but may also be called multiple times if the key is held down (key repeating); or called without key presses if another input method was used (e.g., a pen input). We should always use this method for interpreting text, as the key symbols often have complex mappings to their unicode representation which this event takes care of.
We can create a window with the help of command given below
pyglet.window.Window(width, height, title)
Below is the syntax of the on text event, this method get called when this event is triggered
@window.event def on_text(text): print("On text event")
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 = "w3wiki" # creating a label with font = times roman # font size = 36 # aligning it to the centre label = pyglet.text.Label(text, font_name = 'Times New Roman' , font_size = 36 , x = window.width / / 2 , y = window.height / / 2 , anchor_x = 'center' , anchor_y = 'center' ) new_label = pyglet.text.Label(text, font_name = 'Times New Roman' , font_size = 10 , x = 25 , y = 25 ) # on draw event @window .event def on_draw(): # clearing the window window.clear() # drawing the label on the window label.draw() # key press event @window .event def on_key_press(symbol, modifier): # key "C" get press if symbol = = pyglet.window.key.C: print ( "Key C is pressed" ) # on text event @window .event def on_text(text): # printing some message print ( "You are entering : " + text) # 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 :
You are entering : g You are entering : e You are entering : e You are entering : k
