In this article we will see how we can trigger on key press 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). A key on the keyboard was pressed (and held down). In pyglet 1.0 the default handler sets has_exit to True if the ESC key is pressed. Key press event is the major event to handle keyboard inputs.
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 key press event, this method get called when this event is triggered :
@window.event
def on_key_press(symbol, modifiers):
print("Key is pressed")
Example : 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 = "GeeksforLazyroar" # creating a window window = pyglet.window.Window(width, height, title) # text text = "Lazyroar" # 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): print("Some key is pressed") # key "C" get press if symbol == pyglet.window.key.C: print("Key C is pressed") # on hide event @window.event def on_hide(): # printing some message print("Window is minimized") # 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 :
Some key is pressed Key C is pressed
