Here's what I got from a little experimentation and print
box.cancel.bind.__doc__.
>>> def bar(action):
... print action
>>> import Tix
>>> root = Tix.Tk()
>>> box = Tix.ExFileSelectBox(root)
>>> box.pack()
>>> box.cancel.bind("<ButtonPress-1>", bar)
'-1212073588bar'
>>> <Tkinter.Event instance at 0xb779c0ec>
<Tkinter.Event instance at 0xb779c0ec>
<Tkinter.Event instance at 0xb779c0ec>
If you have a look at box.cancel.bind.__doc__ you can find everything
you can put into the SEQUENCE string "<ButtonPress-1>" is left mouse
click.
