Detailed Description

A validator groupping multiple QValidators.

KDbMultiValidator behaves like normal KDbValidator, but it allows to add define more than one different validator. Given validation is successful if every subvalidator accepted given value.

• acceptsEmptyValue() is used globally here (no matter what is defined in subvalidators).
• result of calling check() depends on value of check() returned by subvalidators:
  • Error is returned if at least one subvalidator returned Error;
  • Warning is returned if at least one subvalidator returned Warning and no validator returned error;
  • Ok is returned only if exactly all subvalidators returned Ok.
  • If there is no subvalidators defined, Error is always returned.
  • If a given subvalidator is not of class KDbValidator but ust QValidator, it's assumed it's check() method returned Ok.
• result of calling validate() (a method implemented for QValidator) depends on value of validate() returned by subvalidators:
  • Invalid is returned if at least one subvalidator returned Invalid
  • Intermediate is returned if at least one subvalidator returned Intermediate
  • Acceptable is returned if exactly all subvalidators returned Acceptable.
  • If there is no subvalidators defined, Invalid is always returned.

If there are no subvalidators, the multi validator always accepts the input.

Constructor & Destructor Documentation

KDbMultiValidator() [1/2]

KDbMultiValidator::KDbMultiValidator ( QObject * parent = nullptr )

explicit

Constructs multivalidator with no subvalidators defined. You can add more validators with addSubvalidator().

Definition at line 107 of file KDbValidator.cpp.

KDbMultiValidator() [2/2]

KDbMultiValidator::KDbMultiValidator ( QValidator * validator, QObject * parent = nullptr )

explicit

Constructs multivalidator with one validator validator. It will be owned if has no parent defined. You can add more validators with addSubvalidator().

Definition at line 113 of file KDbValidator.cpp.

~KDbMultiValidator()

KDbMultiValidator::~KDbMultiValidator ( )

override

Definition at line 120 of file KDbValidator.cpp.

Member Function Documentation

addSubvalidator()

void KDbMultiValidator::addSubvalidator	(	QValidator *	validator,
		bool	owned = true )

Adds validator validator as another subvalidator. Subvalidator will be owned by this multivalidator if owned is true and its parent is nullptr.

Definition at line 125 of file KDbValidator.cpp.

fixup()

void KDbMultiValidator::fixup ( QString & input ) const

overridevirtual

Calls QValidator::fixup() on every subvalidator. This may be senseless to use this methog in certain cases (can return weir results), so think twice before..

Reimplemented from QValidator.

Definition at line 145 of file KDbValidator.cpp.

internalCheck()

KDbValidator::Result KDbMultiValidator::internalCheck ( const QString & valueName, const QVariant & value, QString * message, QString * details )

overrideprotectedvirtual

Reimplemented from KDbValidator.

Definition at line 152 of file KDbValidator.cpp.

validate()

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

overridevirtual

Reimplemented to call validate() on subvalidators.

Implements QValidator.
