How to determine row position in a list box

[Scott Holmes]

I've been trying to understand nearest(y) but I'm not getting it.  I 
have a ScrolledListBox with a list of people's names.  I also have a 
parallel list of the unique people numbers used in the PostgreSQL 
database.  When a name is selected from the scrolled list, I need to 
determine the index value and then find the corresponding people number.


     def selectionCommand(self):
         sels = self.box.getcurselection()
         if len(sels) == 0:
             print 'No selection'
         else:
             print 'Selection:', sels[0]
             print self.nmbr_list[self.box[0].nearest(y)]
             self.lkupTopLevel.withdraw()

Where do I obtain the value y used in nearest(y)?
