  39 \begin{twocollist}
  40 \twocolitem{{\bf wxFILTER\_NONE}}{No filtering takes place.}
  41 \twocolitem{{\bf wxFILTER\_ASCII}}{Non-ASCII characters are filtered out.}
  42 \twocolitem{{\bf wxFILTER\_ALPHA}}{Non-alpha characters are filtered out.}
  43 \twocolitem{{\bf wxFILTER\_ALPHANUMERIC}}{Non-alphanumeric characters are filtered out.}
  44 \twocolitem{{\bf wxFILTER\_NUMERIC}}{Non-numeric characters are filtered out.}
  45 \twocolitem{{\bf wxFILTER\_INCLUDE\_LIST}}{Use an include list. The validator
  46 checks if the user input is on the list, complaining if not. See
  47 \helpref{wxTextValidator::SetIncludes}{wxtextvalidatorsetincludes}.}
  48 \twocolitem{{\bf wxFILTER\_EXCLUDE\_LIST}}{Use an exclude list. The validator
  49 checks if the user input is on the list, complaining if it is. See
  50 \helpref{wxTextValidator::SetExcludes}{wxtextvalidatorsetexcludes}.}
  51 \twocolitem{{\bf wxFILTER\_INCLUDE\_CHAR\_LIST}}{Use an include list. The validator
  52 checks if each input character is in the list (one character per list element), complaining if not.
  53 See \helpref{wxTextValidator::SetIncludes}{wxtextvalidatorsetincludes}.}
  54 \twocolitem{{\bf wxFILTER\_EXCLUDE\_CHAR\_LIST}}{Use an include list. The validator
