How can I identify when a Button is released in Tkinter?

Tkinter Python GUI-Programming

In Tkinter, events are generally called by buttons or keys. Whenever the user presses an assigned key or clicks an assigned button, the events get executed. To execute the events, we can bind a button or a key with the callback function.

Consider an application where we need to trigger an event whenever we release the mouse button. This can be achieved by passing the <Button Release> parameter in the bind(<ButtonRelease>, callback) method.

Example

# Import the required libraries
from tkinter import *

# Create an instance of tkinter frame or window
win=Tk()

# Set the size of the window
win.geometry("700x350")

# Define a function on mouse button clicked
def on_click(event):
   label["text"]="Hello, There!"

def on_release(event):
   label["text"]="Button Released!"

# Crate a Label widget
label=Label(win, text="Click anywhere..", font=('Calibri 18 bold'))
label.pack(pady=60)

win.bind("<ButtonPress-1>", on_click)
win.bind("<ButtonRelease-1>", on_release)

win.mainloop()
