ArcGISMapImageSublayer Class | ArcGIS Maps SDK for Qt

Member Function Documentation [explicit] ArcGISMapImageSublayer::ArcGISMapImageSublayer(qint64 id, QObject *parent = nullptr)

Constructor that accepts a sublayer ID.

id - The sublayer ID.
parent - The optional parent object. Defaults to nullptr.

See also ArcGISMapImageSublayer.

ArcGISMapImageSublayer::ArcGISMapImageSublayer(qint64 id, Esri::ArcGISRuntime::SublayerSource *sublayerSource, QObject *parent = nullptr)

Constructor that accepts a sublayer ID and a sublayer source.

id - The sublayer ID.
sublayerSource - The sublayer source. (Can be set only when instantiating.)
parent - The optional parent object. Defaults to nullptr.

Only map services that support dynamic layers will be able to manage sublayers with sublayer sources. The ArcGIS MapServer must have `Supports Dynamic Layers` equal to true in the ArcGIS REST Services Directory. For sublayer sources other than rasters, you must set a renderer.

See also ArcGISMapImageSublayer.

[override virtual noexcept] ArcGISMapImageSublayer::~ArcGISMapImageSublayer()

Destructor.

bool ArcGISMapImageSublayer::isDefaultVisible() const

Returns the sublayer's default visibility.

[since Esri::ArcGISRuntime 100.1] Esri::ArcGISRuntime::LabelDefinitionListModel *ArcGISMapImageSublayer::labelDefinitions() const

Returns the list model of label definitions for this sublayer.

This is only available if the ArcGISMapImageLayer supports dynamic capabilities.

This function was introduced in Esri::ArcGISRuntime 100.1.

[since Esri::ArcGISRuntime 100.1] void ArcGISMapImageSublayer::setDefinitionExpression(const QString &definitionExpression)

Sets the sublayer's definition expression to definitionExpression.

The definition expression is an SQL statement where clause to filter out the features to be displayed. It uses the SQL-92 where clause syntax (https://en.wikipedia.org/wiki/SQL-92). You must 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.

[since Esri::ArcGISRuntime 100.1] void ArcGISMapImageSublayer::setLabelsEnabled(bool labelsEnabled)

Sets whether the sublayer's labels are displayed to labelsEnabled.

This function was introduced in Esri::ArcGISRuntime 100.1.

[since Esri::ArcGISRuntime 100.1] void ArcGISMapImageSublayer::setMaxScale(double maxScale)

Sets the maximum scale at which the sublayer is visible to maxScale.

This function was introduced in Esri::ArcGISRuntime 100.1.

[since Esri::ArcGISRuntime 100.1] void ArcGISMapImageSublayer::setMinScale(double minScale)

Sets the minimum scale at which the sublayer is visible to minScale.

This function was introduced in Esri::ArcGISRuntime 100.1.

void ArcGISMapImageSublayer::setName(const QString &name)

Sets the name of the sublayer to name.

This can be an empty string.

[since Esri::ArcGISRuntime 100.1] void ArcGISMapImageSublayer::setOpacity(float opacity)

Sets the sublayer's opacity to opacity.

This function was introduced in Esri::ArcGISRuntime 100.1.

[since Esri::ArcGISRuntime 100.1] void ArcGISMapImageSublayer::setRenderer(Esri::ArcGISRuntime::Renderer *renderer)

Sets the renderer that specifies how the features should be symbolized to renderer.

This function was introduced in Esri::ArcGISRuntime 100.1.

[since Esri::ArcGISRuntime 100.1] void ArcGISMapImageSublayer::setScaleSymbols(bool scaleSymbols)

Sets whether the sublayer renders its symbols based on scale to scaleSymbols.

This function was introduced in Esri::ArcGISRuntime 100.1.

Esri::ArcGISRuntime::SublayerSource *ArcGISMapImageSublayer::source() const

Returns the sublayer source.

[since Esri::ArcGISRuntime 100.3] Esri::ArcGISRuntime::ServiceFeatureTable *ArcGISMapImageSublayer::table() const

Returns the sublayer's feature table.

This only applies to sublayers of type "Feature layer" or "Table". This method returns nullptr if the sublayer has not been loaded.

This function was introduced in Esri::ArcGISRuntime 100.3.
