And example is in the FAQ:

    http://library.gnome.org/devel/gtk-faq/stable/x842.html

But if you try to restrict the input in a more complex manner than
limiting the set of characters that can be entered the result is usually
very frustrating to the user.

I suggest to change the text colour to red (or something similar) if
the input is not in valid format.  Then the user has a feedback but is
still free to go through arbitrary intermediate states when editting one
valid input into another.
