Constructor & Destructor Documentation

QgsDateTimeFieldFormatter()

QgsDateTimeFieldFormatter::QgsDateTimeFieldFormatter ( )

default

Default constructor of field formatter for a date time field.

Member Function Documentation

defaultFormat()

QString QgsDateTimeFieldFormatter::defaultFormat ( QVariant::Type  type )

static

Gets the default format in function of the type.

The type is expected to be one of

• QVariant::DateTime
• QVariant::Date
• QVariant::Time

Definition at line 82 of file qgsdatetimefieldformatter.cpp.

id()

QString QgsDateTimeFieldFormatter::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 32 of file qgsdatetimefieldformatter.cpp.

representValue()

QString QgsDateTimeFieldFormatter::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

Reimplemented from QgsFieldFormatter.
