Tkinter Tab orders and keybindings

AFAIK the only 'built-in' way to do this is by controlling the order
in which you *create* the widgets -- which, of course, is not
necessarily related to their positions on screen.

If that doesn't work for you, you might have to write your own 'next'
and 'prev' methods, which would use your own list of widgets. If you
don't need the Tab key for anything else, you could use the following
bindings in your toplevel window.

self.bind_all('<Tab>', self.next)
self.bind_all('<ISO-Left-Tab>', self.prev)

Here, again, I think you would need your own traversal method. Then,
of course, you either include some additional actions in the traversal 
method, or bind <Tab> to a handler that invokes the traversal method + 
something else.

Hope this helps.
