|
A field formatter helps to handle and display values for a field.
|
|
|
|
It allows for using a shared configuration with the editor widgets
|
|
for representation of attribute values.
|
|
Field kits normally have one single instance which is managed by the
|
|
:py:class:`QgsFieldFormatterRegistry`. Custom field formatters should be registered there and
|
|
field formatters for use within code should normally be obtained from there.
|
|
|
|
This is an abstract base class and will always need to be subclassed.

virtual QString id() const = 0;

Returns a unique id for this field formatter.
|
|
This id will later be used to identify this field formatter in the registry with :py:func:`QgsFieldFormatterRegistry.fieldFormatter()`.
|
|
|
|
This id matches the id of a :py:class:`QgsEditorWidgetFactory`.

Create a pretty String representation of the value.
|

virtual Qt::AlignmentFlag alignmentFlag( QgsVectorLayer *layer, int fieldIndex, const QVariantMap &config ) const;

%Docstring
|

Returns the alignment for a particular field. By default this will consider the field type but can be overwritten if mapped
|
|
values are represented.

%End

virtual QVariant createCache( QgsVectorLayer *layer, int fieldIndex, const QVariantMap &config ) const;
|
|
%Docstring
|
|
Create a cache for a given field.
|
|
|
|
This will be used in situations where a field is being represented various times in a loop. And will be passed
|
|
to other methods on :py:class:`QgsFieldKit` and :py:class:`QgsEditorWidgetWrapper`.
|
|
|
|
For example, the attribute table will create a cache once for each field and then use this
|
|
cache for representation. The :py:class:`QgsValueRelationFieldFormatter` and :py:class:`QgsValueRelationEditorWidget`
|
|
implement this functionality to create a lookuptable once (a QVariantMap / dict) and are
|
|
make use of a cache if present.

virtual QVariantList availableValues( const QVariantMap &config, int countLimit, const QgsFieldFormatterContext &context ) const;

Returns a list of the values that would be possible to select with this widget type
|
|
On a RelationReference that would be the parents ids or on ValueMap all the configured keys
|
|
according to the settings in the ``config``
