tkinter entry eat chars?

In a Tkinter entry field (or Pmw entry)
how could I eat charactres?

Say a certain char is keyed in. Say &
I notice in the event handler for <key>.
I don't want any more charactres to display or
be in the field until I handle a see, in the
event handler, another character. Say ?

Can the event handler somehow destroy the char?

Thanks

You can use the textvariable option for the Entry widget. Set a bind event
for this widget that when any key pressed the StringVar() will be polled via
StringVar().get(). You do some checking for certain chars you don't want
entered and then delete them as they occur.
