How to make same event mean different things for different functions in tkinter?

Question

I was wondering if it was possible to have the same event(like-R-click/R-mouse-press), mean different things for different functions:

For example: Moving an object on R-mouse press and also having the same event used for changing the shape of an object(by mouse press and drag).

How can i do this?

Answer 1

You can define event pattern in tkinter and they have the form of <modifier-modifier-type-detail> .

So what you can do is to combine event modifier such as Button3 and types as Motion with each other, (eg) root.bind('<Button3-Motion>',button3motion)

An example can be found below:

import tkinter as tk

def button3press(event):
    print('right click')

def button3release(event):
    print('right click ended')

def button3motion(event):
    print('mouse move while right click')

root = tk.Tk()
root.bind('<ButtonPress-3>',button3press)
root.bind('<ButtonRelease-3>',button3release)
root.bind('<B3-Motion>',button3motion)
root.mainloop()
