Oh ok this is deeper into Tkinter water.....
from pydoc Tkinter.Listbox:-
<snip>
| nearest(self, y)
| Get index of item which is nearest to y coordinate Y.
So the nearest() method should do what you want....... however in this case
I suspect you will need to get the event.y NOT event.y_root and I really
don't know what will happen if you have a ScrollBar........
lets see.....
Python 2.2.1 (#3, May 29 2002, 20:32:44)
[GCC 2.96 20000731 (Red Hat Linux 7.1 2.96-98)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from Tkinter import *
>>>
>>>
>>> root=Tk()
>>> lb=Listbox(root)
>>> lb.insert("end", "one")
>>> lb.insert("end", "two")
>>> lb.insert("end", "three")
>>> lb.pack()
>>> def binding(event):
... print lb.get(first=lb.nearest(event.y))
...
>>> lb.bind("<3>", binding)
'135833868binding'
>>> two
three
two
one
one
I'll leave the ScrollBar issue to you!
