Events and the Listbox widget

[Hans Kristian Ruud]

I have generated a listbox, and wish to extract some information when a
user
  clicks on an item:

          list = Listbox(canvas,width=15 )
          list.pack(side=TOP)
          list.bind('<ButtonPress>', chooseSheet)

          def chooseSheet(event):
                  listbox = event.widget
                  selected = listbox.curselection()
                  setCurSheet( selected[0] )


  My problem is that the list of selected values from
listbox.curselection()
  is not updated until after chooseSheet is called, i.e. the function

  listbox.curselection()

  returns the PREVIOUS element that was clicked.

  Originally I had bound the function to root, and then it worked fine,
however
  I do not want the function chooseSheet to be executed when I click on
buttons
  and such that I have added later.

  Any ideas?
  Thanks in advance
