Answer
The event for clicking the left mouse button twice is "Double-Button-1".
Work Step by Step
Here is an example of how to bind a canvas to the "Double-Button-1" event and call a callback function "on_double_click":
from tkinter import *
def on_double_click(event):
print("Double clicked at", event.x, event.y)
root = Tk()
canvas = Canvas(root, width=200, height=200)
canvas.pack()
canvas.bind("", on_double_click)
root.mainloop()
In this example, the callback function "on_double_click" will be called and print the coordinates of the mouse pointer when the left mouse button is double-clicked on the canvas.
