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.
