  11
  12     wxTextValidator validates text controls, providing a variety of filtering
  13     behaviours.
  14
  15     For more information, please see @ref overview_validator.
  16
  17     @beginStyleTable
  18     @style{wxFILTER_NONE}
  19            No filtering takes place.
  20     @style{wxFILTER_ASCII}
  21            Non-ASCII characters are filtered out.
  22     @style{wxFILTER_ALPHA}
  23            Non-alpha characters are filtered out.
  24     @style{wxFILTER_ALPHANUMERIC}
  25            Non-alphanumeric characters are filtered out.
  26     @style{wxFILTER_NUMERIC}
  27            Non-numeric characters are filtered out.
  28     @style{wxFILTER_INCLUDE_LIST}
  29            Use an include list. The validator checks if the user input is on
  30            the list, complaining if not. See SetIncludes().
  31     @style{wxFILTER_EXCLUDE_LIST}
  32            Use an exclude list. The validator checks if the user input is on
  33            the list, complaining if it is. See SetExcludes().
  34     @style{wxFILTER_INCLUDE_CHAR_LIST}
  35            Use an include list. The validator checks if each input character is
  36            in the list (one character per list element), complaining if not.
  37            See SetIncludes().
  38     @style{wxFILTER_EXCLUDE_CHAR_LIST}
  39            Use an include list. The validator checks if each input character is
  40            in the list (one character per list element), complaining if it is.
  41            See SetExcludes().
