| ) |  |

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

Parameters

  style | One or more of the wxTextValidatorStyle styles. See SetStyle().
  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).

## ◆ IsCharExcluded()

bool wxTextValidator::IsCharExcluded | ( | const wxUniChar & | c | ) | const
| protected

Returns true if the char c is not allowed to be in the user input string.

(characters set by SetCharExcludes() or AddCharExcludes()).

Since
  3.1.3

## ◆ IsCharIncluded()

bool wxTextValidator::IsCharIncluded | ( | const wxUniChar & | c | ) | const
| protected

Returns true if the char c is allowed to be in the user input string.

| protected

Returns true if the string str is one of the excludes strings set by SetExcludes() or AddExclude().

bool wxTextValidator::IsIncluded | ( | const wxString & | str | ) | const
| protected

Returns true if the string str is one of the includes strings set by SetIncludes() or AddInclude().

Notice that unless wxFILTER_INCLUDE_LIST is specified (in which case the validator will complain if the user input is not on the list), the list will be ignored and won't participate in the validation process.

Since
  3.1.3

## ◆ IsValid()

virtual wxString wxTextValidator::IsValid | ( | const wxString & | val | ) | const
| virtual

Returns the error message if the contents of val are invalid or the empty string if val is valid.

Sets the exclude char list (invalid characters for the user input).

Note
  Beware that exclusion takes priority over inclusion.
  This function may cancel the effect of `wxFILTER_SPACE` if the passed in string chars contains the space character.

## ◆ SetCharIncludes()

void wxTextValidator::SetCharIncludes | ( | const wxString & | chars | ) |

Sets the include char list (additional valid values for the user input).

Sets the include list (valid values for the user input).

See also
  IsIncluded()

## ◆ SetStyle()

void wxTextValidator::SetStyle | ( | long | style | ) |

Sets the validator style which must be a combination of one or more of the wxTextValidatorStyle values.

Note that not all possible combinations make sense! Also, some combinations have shorter and more idiomatic alternative, e.g. `wxFILTER_ALPHANUMERIC` can be used instead of `wxFILTER_ALPHA|wxFILTER_DIGITS`.

| virtual

Transfers the value in the text control to the string.

Reimplemented from wxValidator.
