        Constructor, taking a style and optional pointer to a wxString variable.

        @param style
            A bitlist of flags, which can be:







            wxFILTER_NONE




            No filtering takes place.





            wxFILTER_ASCII




            Non-ASCII characters are filtered out.





            wxFILTER_ALPHA




            Non-alpha characters are filtered out.





            wxFILTER_ALPHANUMERIC




            Non-alphanumeric characters are filtered out.





            wxFILTER_NUMERIC




            Non-numeric characters are filtered out.





            wxFILTER_INCLUDE_LIST




            Use an include list. The validator
            checks if the user input is on the list, complaining if not. See
            SetIncludes().





            wxFILTER_EXCLUDE_LIST




            Use an exclude list. The validator
            checks if the user input is on the list, complaining if it is. See
            SetExcludes().





            wxFILTER_INCLUDE_CHAR_LIST




            Use an include list. The validator
            checks if each input character is in the list (one character per list
        element), complaining if not.
            See SetIncludes().





            wxFILTER_EXCLUDE_CHAR_LIST




            Use an include list. The validator
            checks if each input character is in the list (one character per list
        element), complaining if it is.
            See SetExcludes().
        @param valPtr
            A pointer to a wxString variable that contains the value. This variable
            should have a lifetime equal to or longer than the validator lifetime
        (which is usually
            determined by the lifetime of the window).
