class QgsFieldFormatter

|
|
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
|
|
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.

%Docstring
|
|
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`.

%Docstring
|
|
Create a pretty String representation of the value.
|
|
|
|
:return: By default the string representation of the provided value as implied by the field definition is returned.

|

If the default sort order should be overwritten for this widget, you can transform the value in here.
|
|
|
|
:return: an unmodified value by default.

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.
|
|
|
|
.. versionadded:: 3.0

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 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 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.
