Constructor & Destructor Documentation

◆ QgsKeyValueFieldFormatter()

QgsKeyValueFieldFormatter::QgsKeyValueFieldFormatter ( )
default

Default constructor of field formatter for a key value field.

Member Function Documentation

◆ id()

QString QgsKeyValueFieldFormatter::id ( ) const
overridevirtual

Returns a unique id for this field formatter.

This id will later be used to identify this field formatter in the registry with QgsFieldFormatterRegistry::fieldFormatter().

This id matches the id of a QgsEditorWidgetFactory.

Implements QgsFieldFormatter.

Definition at line 22 of file qgskeyvaluefieldformatter.cpp.

◆ representValue()

QString QgsKeyValueFieldFormatter::representValue ( QgsVectorLayer layer,
int  fieldIndex,
const QVariantMap &  config,
const QVariant &  cache,
const QVariant &  value 
) const
overridevirtual

Create a pretty String representation of the value.

Returns
By default the string representation of the provided value as implied by the field definition is returned.
Since
QGIS 3.0
