Detailed Description

Field formatter for a key value field.

This represents a list type value. Values will be represented as a colon-delimited and comma-separated list.

E.g. "color: yellow, amount: 5"

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 21 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.
