[Tutor] Popup menu for items in a tkinter listbox

[Ellen Reitmayr]

hi,

I'm trying to set up an 'add contact from addressbook' dialog with
tkinter. There are three listboxes on the right side, showing the
selected contacts (to, cc, bcc). 
Now I want to add a popup menu to the single entries of each list in
order to remove the selected item. But I'm faces several problems:

- I bound <button-3> with each of the three listboxes to invoke the
popup, and <button-1> with the menu to invoke the remove-method: How do
I know which listbox is the target list? 'event.widget' does not work,
as the menu is the widget. Do I have to compare the x/y-coordinates? Or
is there a simpler way to identify the widgets at the current mouse
position (I did not use a canvas, so find_overlapping(x1,y1,x2,y2) does
not work).
- But actually I'm not just interested in the whole list, but in the
list entries. Is there a way to bind the popups to the list entries, not
to the whole list? And if that is not possible - How can I make a list
item be selected when I right-click it (if I do not know the index)?

Maybe someone can help me, or tell me were to find a code example for
this problem?

Thanks and have a nice day,
ellen

def popup(event):
    removeMenu.post(event.x_root, event.y_root)

def removeContact(event):
	# ???? how can I refer to the correct list/list item??

#
#[....]
#

removeMenu = Menu(root, tearoff=0)
removeMenu.add_command(label="Entfernen",)
removeMenu.bind("<Button-1>",removeContact)

toList.bind("<Button-3>",popup)
ccList.bind("<Button-3>",popup)
bccList.bind("<Button-3>",popup)
