Detailed Description

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

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

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

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

Member Function Documentation

◆ acceptsEmptyValue()

bool KDbValidator::acceptsEmptyValue ( ) const
Returns
true if the validator accepts empty values
See also
setAcceptsEmptyValue()

Definition at line 95 of file KDbValidator.cpp.

◆ addChildValidator()

void KDbValidator::addChildValidator ( KDbValidator v)

Adds a child validator v.

◆ check()

KDbValidator::Result KDbValidator::check ( const QString valueName,
const QVariant v,
QString message,
QString details 
)

Checks if value value 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.

Definition at line 60 of file KDbValidator.cpp.

◆ messageColumnNotEmpty()

const QString KDbValidator::messageColumnNotEmpty ( )
static

A generic error/warning message "... value has to be entered.".

Definition at line 100 of file KDbValidator.cpp.

◆ setAcceptsEmptyValue()

void KDbValidator::setAcceptsEmptyValue ( bool  set)

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

Definition at line 90 of file KDbValidator.cpp.

◆ validate()

QValidator::State KDbValidator::validate ( QString input,
int &  pos 
) const
overridevirtual

This implementation always returns value QValidator::Acceptable.

Implements QValidator.

Reimplemented in KDbMultiValidator.
