Right click on Mac with Tkinter

[sudiptachatterjee]

Hi everyone,

I am building a GUI app using python and Tkinter. I used bind() to attach the right-click event on <Button-3> for executing some commands (to popup a menu, specifically) --- and it is working fine on the PC. However, on a Mac laptop or machine, it just doesn't work (using Ctrl-Click, that is).

I found this old thread in the archives too: http://www.thescripts.com/forum/thread493721.html but there aren't any answers. Can someone please help me out?

I'm no Mac user, but you can get a bitmap of the keys that are down from the Tkinter.Event.state

from Tkinter import *
if __name__ == "__main__":
    root = Tk()
 
    def OnButton(event):
        print event.state
 
    button = Button(root, text='test')
    button.bind("<Button-1>", OnButton)
    button.pack()
 
 
    root.mainloop()
# No Keys pressed
##8
# Sift down
##9
# Ctrl down
##12

Thanks a lot for the reply. But I am not being able to bind to the right-click in the first place. In your example, when I use

from Tkinter import *
if __name__ == "__main__":
    root = Tk()
 
    def OnButton(event):
        print event.state
 
    button = Button(root, text='test')
    button.bind("<Button-3>", OnButton)
    button.pack()
 
 
    root.mainloop()
 

I keep getting a '0' at the shell prompt, which I was getting with a binding to button 1 as well on the PC. On a MAC, however, the right-click just simply doesn't work.

Thanks a lot for replying --- I'll hunt around and post a solution here if I find one

Bind to the left-click and get the state of the event to see if the ctrl key is down, then process as if it were a right click (unless the Event class is defined diferently on the Mac).

Is it possible (have you tried) that a one-button mouse generates <Button-2> events?
