class MultiValidator

Detailed Description

A validator extending TQValidator with offline-checking for value's validity.

The offline-checking for value's validity is provided by Validator::check() method. The validator groups two purposes into one container:

  • string validator for line editors (online checking, "on typing");
  • offline-checking for TQVariant values, reimplementing validate().

It also offers error and warning messages for check() method. You may need to reimplement:

Member Function Documentation

◆ acceptsEmptyValue()

bool KexiUtils::Validator::acceptsEmptyValue ( ) const
inline
Returns
true if the validator accepts empty values

setAcceptsEmptyValue()

Definition at line 59 of file validator.h.

◆ addChildValidator()

void KexiUtils::Validator::addChildValidator ( Validator * v)

Adds a child validator v.

◆ check()

Validator::Result Validator::check ( const TQString & valueName,
const TQVariant & v,
TQString & message,
TQString & details )

Checks if value v is ok and returns one of Result value:

  • Error is returned on error;
  • Ok on success;
  • Warning if there is something to warn about. In any case except Ok, i18n'ed message will be set in message and (optionally) datails are set in details, e.g. for use in a message box. valueName can be used to contruct message as well, for example: "[valueName] is not a valid login name". Depending on acceptsEmptyValue(), immediately accepts empty values or not.

const TQVariant & v,
TQString & message,
TQString & details )
protectedvirtual

◆ msgColumnNotEmpty()

const TQString KexiUtils::Validator::msgColumnNotEmpty ( )
inlinestatic

A generic error/warning message.

Definition at line 77 of file validator.h.

◆ setAcceptsEmptyValue()

void KexiUtils::Validator::setAcceptsEmptyValue ( bool set)
inline

Sets accepting empty values on (true) or off (false). By default the validator does not accepts empty values.

Definition at line 55 of file validator.h.

◆ validate()

TQValidator::State Validator::validate ( TQString & input,
int & pos ) const
virtual

This implementation always returns value TQValidator::Acceptable.

Reimplemented in KexiUtils::IdentifierValidator, and KexiUtils::MultiValidator.
