[wxPython-users] Re: Custom validator

[Josiah Carlson]

Almost.  If you use that regular expression, then a user who planned on
writing '.5' wouldn't be able to type the leading '.'.  One could use
r'^(\d*\.\d*)$' with some post-processing afterwards to make it so that
an empty entry or just a plain '.' turns into a zero.
