AggregateGeoElement Class

Member Function Documentation

[override virtual] AggregateGeoElement::~AggregateGeoElement()

Destructor.

[override virtual] Esri::ArcGISRuntime::AttributeListModel *AggregateGeoElement::attributes() const

Reimplements: GeoElement::attributes() const.

Returns the attributes of the GeoElement as a collection of name/value pairs.

[since Esri::ArcGISRuntime 200.4] QFuture<QList<Esri::ArcGISRuntime::GeoElement *>> AggregateGeoElement::geoElementsAsync(QObject *parent = nullptr)

Gets the collection of geoelements represented by this aggregate geoelement.

For an aggregate geoelement on a feature layer, this method returns a collection of features. For a graphics overlay, it returns a collection of graphics.

• parent - The optional parent QObject.

As a user navigates the map, aggregate geoelements update dynamically depending on the map's scale and extent. When aggregate geoelements are re-created, new aggregate geoelements are drawn. References to AggregateGeoElement instances that are no longer drawn on the map retain their association to the geoelements they aggregated.

This method returns a QFuture for the asynchronous operation. Use future.then() to continue processing when the operation completes. Use future.onFailed() to handle exceptions of type ErrorException.

See Working with QFuture for further details.

This function was introduced in Esri::ArcGISRuntime 200.4.

[override virtual] Esri::ArcGISRuntime::Geometry AggregateGeoElement::geometry() const

Reimplements: GeoElement::geometry() const.

Returns the geometry defines the shape and location of the GeoElement.

See also setGeometry().

[since Esri::ArcGISRuntime 200.4] bool AggregateGeoElement::isSelected() const

Returns true if the aggregate geoelement is selected, false otherwise.

Selecting an AggregateGeoElement adds a temporary visual selection halo around the aggregate geoelement. Selected aggregate geoelements are rendered according to the GeoView::selectionProperties.

As a user navigates the map, aggregate geoelements update dynamically depending on the map's scale and extent. When aggregate geoelements are re-created, new aggregate geoelements are drawn. This clears selection halos of any previously referenced AggregateGeoElement. However, properties of the previous referenced aggregate geoelements, such as their geometry, attributes, and associated underlying geoelements can still be accessed.

Note that the selection halo that highlights the an aggregate geoelement is transient. In addition to the map's scale and extent changes, updates to the underlying properties of AggregationFeatureReduction also result in aggregate geoelements being re-created and re-drawn. When this happens, the existing selection halos on the aggregate geoelements are cleared.

[override virtual] void AggregateGeoElement::setGeometry(const Esri::ArcGISRuntime::Geometry &geometry)

Reimplements: GeoElement::setGeometry(const Esri::ArcGISRuntime::Geometry &geometry).

Sets the geometry to geometry.

See also geometry.

[since Esri::ArcGISRuntime 200.4] void AggregateGeoElement::setSelected(bool selected)

Sets the selected to selected.

This function was introduced in Esri::ArcGISRuntime 200.4.
