## Constructor & Destructor Documentation

wxTextValidator::wxTextValidator | ( | const wxTextValidator & | validator | ) |

Default constructor.

wxTextValidator::wxTextValidator | ( | long | style = `wxFILTER_NONE`,
|  | wxString * | valPtr = `NULL`
| ) |  |

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).

## Member Function Documentation

virtual wxObject* wxTextValidator::Clone | ( |  | ) | const
| virtual

Clones the text validator using the copy constructor.

Reimplemented from wxValidator.

bool wxTextValidator::ContainsExcludedCharacters | ( | const wxString & | val | ) | const
| protected

Returns true if at least one character of the given val string is present in the exclude list (set by SetExcludes() or SetCharExcludes()).

bool wxTextValidator::ContainsOnlyIncludedCharacters | ( | const wxString & | val | ) | const
| protected

Returns true if all the characters of the given val string are present in the include list (set by SetIncludes() or SetCharIncludes()).

wxArrayString& wxTextValidator::GetExcludes | ( |  | ) |

Returns a reference to the exclude list (the list of invalid values).

wxArrayString& wxTextValidator::GetIncludes | ( |  | ) |

Returns a reference to the include list (the list of valid values).

long wxTextValidator::GetStyle | ( |  | ) | const

Returns the validator style.

  HasFlag()

bool wxTextValidator::HasFlag | ( | wxTextValidatorStyle | style | ) | const

Returns true if the given style bit is set in the current style.

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

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

void wxTextValidator::OnChar | ( | wxKeyEvent & | event | ) |

Receives character input from the window and filters it according to the current validator style.

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

Breaks the given chars strings in single characters and sets the internal wxArrayString used to store the "excluded" characters (see SetExcludes()).

This function is mostly useful when `wxFILTER_EXCLUDE_CHAR_LIST` was used.

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

Breaks the given chars strings in single characters and sets the internal wxArrayString used to store the "included" characters (see SetIncludes()).

This function is mostly useful when `wxFILTER_INCLUDE_CHAR_LIST` was used.

void wxTextValidator::SetExcludes | ( | const wxArrayString & | stringList | ) |

Sets the exclude list (invalid values for the user input).

void wxTextValidator::SetIncludes | ( | const wxArrayString & | stringList | ) |

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

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 note that the order in which the checks are performed is important, in case you specify more than a single style. wxTextValidator will perform the checks in the same definition order used in the wxTextValidatorStyle enumeration.

virtual bool wxTextValidator::TransferFromWindow | ( |  | ) |
| virtual

Transfers the value in the text control to the string.

Reimplemented from wxValidator.

virtual bool wxTextValidator::TransferToWindow | ( |  | ) |
| virtual

Transfers the string value to the text control.

Reimplemented from wxValidator.

virtual bool wxTextValidator::Validate | ( | wxWindow * | parent | ) |
| virtual
