Question on using the mouse in scrolled list applications

[mongo57a at comcast.net]

Hi all!

What I want to do is use a button to capture the position/value of the
selected item in a scrolled list. So the user selects the item in the list
with a single click of the left mouse button and then clicks a button.
Should be easy - I'm just not getting it......

Created a class (ScrolledList) for a scrolled list which works fine. Created
another class (aaaaa) which populates the list - and it works fine. Created
a handler under ScrolledList (handleList) which should trap the results of
the bind (makeWidgets). Right now, all I'm trying to do is just print out
the value (just testing..) - but my logic is incorrect (actually, I think
that the logic may be correct - it's just in the wrong place...).

class ScrolledList(Frame):
    def __init__(self, options, parent=None):
........
        self.makeWidgets(options)

    def handleList(self, event):
        index = self.listbox.curselection()
        label = self.listbox.get(index)                   # fetch selection
       text
        print "label is ", label

    def makeWidgets(self, options):
.........
        list.bind('<Button-1>', self.handleList)          # set event
       handler

Class aaaaa
     def update_strategy_code(self):
..........
        ScrolledList(options)
        Button(self, text='Update',
       command=self.edit_strategy_code).pack(side=LEFT)

     def edit_strategy_code(self):
        label=self.listbox.get(ACTIVE)
        print 'info2=',label

Also, how do I make the mouse appear essentially as it does in an MS
environment - namely, the ability to select a range of items using the shift
key in combination with the mouse and the cntl key in combination with the
mouse for the same application?

TIA

-Andy
