FieldDomainType
Types of field domain.
Definition qgis.h:2662
Abstract base class for widgets which configure the extended properties of a QgsFieldDomain subclass.
virtual QgsFieldDomain * createFieldDomain(const QString &name, const QString &description, QVariant::Type fieldType) const =0
Creates a new field domain using the properties from the widget.
void changed()
Emitted whenever the field domain configuration in the widget changes.
virtual bool isValid() const =0
Returns true if the widget currently represents a valid field domain configuration.
virtual void setFieldDomain(const QgsFieldDomain *domain)=0
Sets the current field domain to show properties for in the widget.
A widget for configuration of the extended properties of a QgsCodedFieldDomain.
A table model for representing the values in a QgsCodedValue list.
QList< QgsCodedValue > values() const
Returns the values from the model.
A dialog for configuration of the properties of a QgsFieldDomain.
A widget for configuration of the properties of a QgsFieldDomain.
void validityChanged(bool isValid)
Emitted whenever the validity of the field domain configuration in the widget changes.
Base class for field domains.
A widget for configuration of the extended properties of a QgsGlobFieldDomain.
A widget for configuration of the extended properties of a QgsRangeFieldDomain.
