PYGLET – Accessing Label Text Font Size Property

0 0 1 minute read

In this article we will see how we can access the label text font size property 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). In order to show text or message we use html label object. A label is a graphical control element which displays text on a form. It is usually a static control; having no interactivity. In metal typesetting, a font was a particular size, weight and style of a typeface. Each font was a matched set of type, one piece (called a “sort”) for each glyph, and a typeface consisting of a range of fonts that shared an overall design.
We can create a window and label with the help of commands given below

# creating window
window = pyglet.window.Window(width, height, title)

# creating a label
label = pyglet.text.Label(text, font_name, font_size, x, y)

In order to create window we use font_size attribute with the label object
Syntax : label.font_size
Argument : It takes no argument
Return : It returns float

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 = "Geeksforzambiatek"
 
# creating a window
window = pyglet.window.Window(width, height, title)
 
# text 
text = "Welcome tozambiatek"
 
# creating a label with font = times roman
# font size = 36
# aligning it to the center
label = pyglet.text.Label(text,
                          font_name ='Times New Roman',
                          font_size = 28,
                          x = 20, y = window.height//2, )
 
# accessing font size property of the label
# setting new font size
label.font_size = 15
 
# 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:
         
        # 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()
