PYGLET – On Text Motion Select Event
  • Last Updated : 22 Sep, 2020

In this article we will see how we can trigger on text motion select 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). The user moved the text input cursor while extending the selection. Typically this is called after on_key_press() and before on_key_release(), but may also be called multiple times if the key is help down (key repeating). We should always use this method for responding to text selection events rather than the raw on_key_press(), as different platforms have different default keyboard mappings, and key repeats are handled correctly.

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 motion, this method get called when this event is triggered

@window.event       
def on_text_motion_select(motion):
    print("Motion Selected")

Below is the implementation




# 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 = "Geeksforgeeks"
  
# creating a window
window = pyglet.window.Window(width, height, title)
  
# text 
text = "GeeksforGeeks"
  
# 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 motion select event
@window.event
def on_text_motion_select(motion):
      
    # prinitng message
    print("Motion Selected")
      
  
# 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()
