bind <Button-3><Alt>

[Agent Drek]

Hey there...

I want to have a bunch of Checkbuttons that are bound to alt-rightclick...
I can't figure out the syntax to do a multiple bind <Button-3><Alt>

thanks for any pointers you can give me.

I've got this far with the newsgroup archives and the doc's:

#!/usr/bin/env python

from Tkinter import *
root = Tk()

def callback(event):
    event.widget.toggle()

frame = Checkbutton(root, state='disabled')
# XXX put Alt-Button-3 here somehow...
frame.bind("<Button-3>", callback)
frame.pack()

root.mainloop()
