A number of questions, for which I've not found the answer in my Python
books nor on the web:
Why does the curselection method of an instance of Tkinter.Listbox return a
single element tuple rather than a scalar?
Why is this element a string rather than an int?
Key bindings do not work for me:
For my listbox:
self.list=Listbox(self) # self is a subclass of Frame.
self.list.bind('<1>',self.ScrollUp) # works
self.list.bind('<Up>',self.ScrollUp) # doesn't work
self.list.bind('<2>',self.ScrollDown) # works
self.list.bind('<Down>',self.ScrollDown) # doesn't work
the bindings to <1> and <2> work (calling the bound methods on mouse
clicks), but the up and down arrow keys on the keyboard do not. What am I
Can someone direct me to examples of Tkinter wheel mouse events so I can
scroll based upon wheel rotation?
Thanks in advance,
PS: Python 2.2.2, TkVersion 8.3
