Event Handling In Tkinter Python means to bind the keyboard or mouse buttons to the Tkinter and use them to call some functions.
We use bind() function to bind keys and functions to each other.
Here, functions can be in-built or made by the programmer.
Let’s see the code to call the in-built function and self made function using the gui.
Code
# importing tkinter
from tkinter import *
# initializing root
root = Tk()
# width and height variables
can_width = 300
can_height = 200
# setting geometry of gui
root.geometry(f"{can_width}x{can_height}")
# setting title of gui
root.title("Event handling")
# creating a label
Label(root, text="Click anywhere").pack()
# initializing variable
i = 0
# defining a function
def me(event):
global i
Label(root, text=f"You clicked me {i} time").pack()
Label(root, text="Double click to exit screen").pack()
i=i+1
# binding mouse left button to root and calling me function
root.bind("<Button-1>", me)
# binding double click mouse left button to root and calling
# in-built quit function
root.bind("<Double-1>", quit)
# calling mainloop
root.mainloop()
Output
Now, here is the code to call the previous functions using the button.
Code
# importing tkinter
from tkinter import *
# initializing root
root = Tk()
# width and height variables
can_width = 300
can_height = 200
# setting geometry of gui
root.geometry(f"{can_width}x{can_height}")
# setting title of gui
root.title("Event handling")
# creating a button
win = Button(root, text="Click me")
# packing the button to gui to show it on screen
win.pack()
# initializing variable
i = 0
# defining a function
def me(event):
global i
Label(root, text=f"You clicked me {i} time").pack()
Label(root, text="Double click to exit screen").pack()
i=i+1
# binding mouse left button to win and calling me function
win.bind("<Button-1>", me)
# binding double click mouse left button to win and calling
# in-built quit function
win.bind("<Double-1>", quit)
# calling mainloop
root.mainloop()
Output
