Getting contents of Text / Entry widgets

Hi,
I'm writing a little utility that uses a Tkinter Text widget (and an
Entry widget). I want to perform an action for every key that is
entered. So I do something like:
def callback(event):
print event.widget.get()
widget=Entry()
widget.bind("<Key>",callback)
The problem with this is that the output generated by callback is
always one character behind. I assume this is because when the event
is generated, the character you've typed hasn't been entered into the
buffer yet. I could modify callback to look something like:
def callback(event):
print event.widget.get() + event.char
But this doesn't handle backspace and delete characters well.
Is there a nice way of retrieving the contents of a Text / Entry widget
every time the widget's text buffer is changed (as opposed to whenever
a key is pressed)?
Thanks,
Chris
