class QgsFieldMappingWidget : QgsPanelWidget
{
%Docstring(signature="appended")
The :py:class:`QgsFieldMappingWidget` class creates a mapping from one set of :py:class:`QgsFields` to another,
for each set of "destination" fields an expression defines how to obtain the values of the
"destination" fields.

    );
%Docstring
Constructs a QgsFieldMappingWidget from a set of ``sourceFields``
and ``destinationFields``, initial values for the expressions can be
optionally specified through ``expressions`` which is a map from the original
field name to the corresponding expression. A ``parent`` object
can also be specified.

Since QGIS 3.44, the ``nativeTypes`` argument can be used to specify the list of
field types natively supported by a data provider. If this list is non-empty, then
the destination field types will be populated accordingly. If the list is empty,
then a set of default native types will be used instead.
%End

    void setDestinationEditable( bool editable );
%Docstring
Sets the destination fields editable state to ``editable``
%End

    bool destinationEditable() const;
%Docstring
Returns ``True`` if the destination fields are editable in the model
%End

    QgsFieldMappingModel *model() const;
%Docstring
Returns the underlying mapping model
%End

    QList<QgsFieldMappingModel::Field> mapping() const;
%Docstring
Returns a list of Field objects representing the current status of the underlying mapping model
%End

    QMap<QString, QgsProperty> fieldPropertyMap() const;
%Docstring
Returns a map of destination field name to :py:class:`QgsProperty` definition for field value,
representing the current status of the widget.

.. seealso:: :py:func:`setFieldPropertyMap`
%End

    void setFieldPropertyMap( const QMap<QString, QgsProperty> &map );
%Docstring
Sets a map of destination field name to :py:class:`QgsProperty` definition for field value.

.. seealso:: :py:func:`fieldPropertyMap`
%End

    QItemSelectionModel *selectionModel();
%Docstring
Returns the selection model
%End

    void setSourceFields( const QgsFields &sourceFields );
%Docstring
Set source fields of the underlying mapping model to ``sourceFields``
%End

    void setSourceLayer( QgsVectorLayer *layer );
%Docstring
Sets a source ``layer`` to use when generating expression previews in the widget.

.. versionadded:: 3.16
%End

    QgsVectorLayer *sourceLayer();
%Docstring
Returns the source layer for use when generating expression previews.

Returned value may be ``None``.

.. versionadded:: 3.16
%End

    void setDestinationFields( const QgsFields &destinationFields, const QMap<QString, QString> &expressions = QMap<QString, QString>() );
%Docstring
Set destination fields to ``destinationFields`` in the underlying model,
initial values for the expressions can be optionally specified through
``expressions`` which is a map from the original field name to the
corresponding expression.
%End

    void setNativeTypes( const QList< QgsVectorDataProvider::NativeType > &nativeTypes );
%Docstring
Sets the list of ``nativeTypes`` supported by a data provider.

If this list is non-empty, then the destination field types will be populated
accordingly. If the list is empty, then a set of default native types will be
used instead.

.. versionadded:: 3.44

    void scrollTo( const QModelIndex &index ) const;
%Docstring
Scroll the fields view to ``index``
%End

    void registerExpressionContextGenerator( const QgsExpressionContextGenerator *generator );
%Docstring
Register an expression context ``generator`` class that will be used to retrieve
an expression context for the widget.
%End

  signals:

    void changed();
%Docstring
Emitted when the fields defined in the widget are changed.
%End

  public slots:

    void appendField( const QgsField &field, const QString &expression = QString() );
%Docstring
Appends a new ``field`` to the model, with an optional ``expression``
%End

    bool removeSelectedFields();
%Docstring
Removes the currently selected field from the model
%End

    bool moveSelectedFieldsUp();
%Docstring
Moves up currently selected field
%End

%Docstring
Moves down the currently selected field
%End

%Docstring
Invert the field selection state.
