Binding mouse double click in Tkinter
Let us suppose that for a particular application, we want to bind the mouse double-click so that it performs some event or operation. We can use the bind(‘<Double-Button-1>’, handler) or bind(‘<Double-Button-2>’, handler) methods to bind the mouse Left or Right Buttons with a handler or a callback function.
Example
In this example, we will create an application that contains a button. When we double click the button, it will open a popup window.
#Import required libraries
from tkinter import *
from tkinter import ttk
#Create an instance of tkinter frame
win= Tk()
#Define the geometry of the window
win.geometry("750x250")
#Define a function
def handler(e):
top= Toplevel(win)
top.geometry("600x200")
Label(top, text= "Hey There!", font= ('Helvetica 15 bold')).pack(pady=30)
#Define a Label in Main window
Label(win, text= "Double Click to Open the Popup",font=('Helvetica 15 underline')).pack(pady=30)
#Create a Button
ttk.Button(win, text= "Click", command=lambda:handler).pack(pady=20)
#Bind the Double Click with the Handler
win.bind('<Double-Button-1>', handler)
win.mainloop()Output
Now, run the above code to display the window.
