ArcGISSublayer Class | ArcGIS Maps SDK for Qt

Destructor.

Reimplements: LayerContent::canChangeVisibility() const.

Returns whether the sublayer's visibility can be changed.

See LayerContent.

Reimplements: Loadable::cancelLoad().

Cancels loading metadata for the object.

Cancels loading the metadata if the object is loading.

See Loadable.

This function was introduced in Esri::ArcGISRuntime 100.1.

Clones and returns the ArcGISSublayer to a new instance with an optional parent.

Returns a new instance of the current sublayer.

This function was introduced in Esri::ArcGISRuntime 200.1.

Returns a SQL statement where clause that stipulates a subset of features to be displayed.

The definition expression string uses the SQL-92 where clause syntax (https://en.wikipedia.org/wiki/SQL-92). Be sure to escape special characters in the expression string as required for your platform. The DATE keyword expects the date format yyyy-mm-dd and the TIMESTAMP keyword expects the time stamp format yyyy-mm-dd hh:mm:ss. For more information, see the ArcGIS Blog article Querying Feature Services Date-Time Queries.

This function was introduced in Esri::ArcGISRuntime 100.1.

Signal emitted when this object is done loading.

• loadError - Details about any error that may have occurred.

Note: If there is a load error it will also be emitted on the errorOccurred signal.

This function was introduced in Esri::ArcGISRuntime 100.1.

See also Loadable and Object.

Returns the id that uniquely identifies this sublayer.

Will return -1 if an error occurs.

Reimplements: LayerContent::isAutoFetchLegendInfos() const.

Returns whether legend infos are automatically fetched by the sublayer's legend info list model.

See LayerContent.

Returns true if the sublayer's labels are enabled, false otherwise.

This function was introduced in Esri::ArcGISRuntime 100.1.

Reimplements: PopupSource::isPopupEnabled() const.

Returns a bool indicating whether the PopupDefinition defined on the PopupSource is enable / disable.

Returns true if the sublayer renderers its symbols based on scale, false otherwise.

This function was introduced in Esri::ArcGISRuntime 100.1.

Reimplements: LayerContent::isShowInLegend() const.

Returns a bool indicating whether the layer content participates in the legend.

See LayerContent.

Reimplements: LayerContent::isVisible() const.

Returns whether the sublayer is enabled to be visible.

See LayerContent.

Reimplements: LayerContent::isVisibleAtScale(double scale) const.

Returns the layer content's effective visibility at the specified scale.

• scale - The scale the visibility has to be calculated for.

Returns the effective layer content visibility. This effective visibility takes care of the effective visibility of the parents at the specified scale. Will return false if an error occurs.

Reimplements: LayerContent::legendInfos() const.

Returns a list of legend information for the sublayer and any of its sublayers.

See LayerContent.

Reimplements: Loadable::load().

Loads the metadata for the object asynchronously.

Loads the metadata if the object is not loaded.

See Loadable.

Reimplements: Loadable::loadStatus() const.

Returns the load status.

See Loadable.

This function was introduced in Esri::ArcGISRuntime 100.1.

See also LoadStatus.

Signal emitted when the loadStatus changes for this object.

This function was introduced in Esri::ArcGISRuntime 100.1.

See also Loadable.

Returns the sublayer's metadata.

The sublayer metadata once the sublayer is loaded. Will return an empty object if an error occurs or if the sublayer is not loaded.

This function was introduced in Esri::ArcGISRuntime 100.1.

Returns the sublayer's maximum scale.

The sublayer maximum scale. Will return NaN if an error occurs.

Returns the sublayer's minimum scale.

The sublayer minimum scale. Will return NaN if an error occurs.

Reimplements: LayerContent::name() const.

Returns the layer content's name.

See LayerContent.

Returns the sublayer's opacity.

Will return NaN if an error occurs.

This function was introduced in Esri::ArcGISRuntime 100.1.

Reimplements: PopupSource::popupDefinition() const.

Returns the pop-up definition.

The PopupDefinition associated with the popup source. A nullptr if an error occurs or if the popup source is not associated with a pop-up definition.

See PopupSource.

See also setPopupDefinition().

Returns the renderer specifying how the features should be symbolized.

This function was introduced in Esri::ArcGISRuntime 100.1.

Reimplements: Loadable::retryLoad().

Loads or retries loading metadata for the object asynchronously.

Will retry loading the metadata if the object is failed to load. Will load the object if it is not loaded. Will not retry to load the object if the object is loaded. Will always call the done loading if this is called.

See Loadable.

This function was introduced in Esri::ArcGISRuntime 100.1.

Reimplements: LayerContent::setAutoFetchLegendInfos(bool autoFetchLegendInfos).

Sets whether legend infos are automatically fetched by the sublayer's legend info list model to autoFetchLegendInfos.
