Detailed Description
Note: You cannot declare or create a component of this type in QML code.
Some layer types contain sublayers. Sublayers contain properties, some of which can be accessed before the layer is loaded. These include:
sublayerIdnamemaxScaleminScalevisible
Other sublayer properties can be accessed only after the Layer is loaded.
See also Cancelable, LayerContent, Loadable, and PopupSource.
Property Documentation
autoFetchLegendInfos : bool |
See also LayerContent.
canChangeVisibility : bool |
See also LayerContent.
[since Esri.ArcGISRuntime 100.1] definitionExpression : string |
Returns the sublayer's definition expression (read-only).
The definition expression string uses the SQL-92 WHERE clause syntax. 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. See the ArcGIS Blog article Querying Feature Services Date-Time Queries for more information.
This property was introduced in Esri.ArcGISRuntime 100.1.
[since Esri.ArcGISRuntime 100.1] error : Error |
[since Esri.ArcGISRuntime 100.1] labelsEnabled : bool |
Returns whether the sublayer's labels are enabled (read-only).
This property was introduced in Esri.ArcGISRuntime 100.1.
legendInfos : LegendInfoListModel |
Returns a list model containing legend infos for the sublayer and any nested sublayers (read-only).
See also LayerContent.
[since Esri.ArcGISRuntime 100.1] loadError : Error |
Returns the load error (read-only).
Note: load errors are also reported on the error property and emit the errorChanged signal.
This property was introduced in Esri.ArcGISRuntime 100.1.
See also Loadable.
[since Esri.ArcGISRuntime 100.1] loadStatus : Enums.LoadStatus |
The Enums.LoadStatus of the Layer.
This property was introduced in Esri.ArcGISRuntime 100.1.
See also Loadable and Enums.LoadStatus.
[since Esri.ArcGISRuntime 100.1] mapServiceSublayerInfo : ArcGISMapServiceSublayerInfo |
Returns the sublayer metadata after the sublayer is loaded (read-only).
Will return a null object if an error occurs or if the sublayer is not loaded.
This property was introduced in Esri.ArcGISRuntime 100.1.
maxScale : double |
Returns the maximum scale at which the sublayer displays (read-only).
minScale : double |
Returns the minimum scale at which the sublayer displays (read-only).
[since Esri.ArcGISRuntime 100.1] opacity : real |
Returns the sublayer's opacity (read-only).
This property was introduced in Esri.ArcGISRuntime 100.1.
popupDefinition : PopupDefinition |
See also PopupSource.
popupEnabled : bool |
See also PopupSource.
[since Esri.ArcGISRuntime 100.1] renderer : Renderer |
Returns the renderer specifying how the features should be symbolized (read-only).
This property was introduced in Esri.ArcGISRuntime 100.1.
[since Esri.ArcGISRuntime 100.1] scaleSymbols : bool |
Returns whether the sublayer renders its symbols based on scale (read-only).
A value of false means the symbols stay the same size in screen units regardless of the map scale.
The default value is false.
This property was introduced in Esri.ArcGISRuntime 100.1.
showInLegend : bool |
See also LayerContent.
subLayerContents : list<LayerContent> |
Returns a list of layer contents for any sublayer (read-only).
See also LayerContent.
[since Esri.ArcGISRuntime 100.1] sublayerId : string |
Returns the sublayer ID (read-only).
Note: The underlying property is represented as a 64-bit integer type. See Accessing 64-bit integer properties from QML.
This property was introduced in Esri.ArcGISRuntime 100.1.
See also sublayerIdAsInt.
[since Esri.ArcGISRuntime 100.3] sublayerIdAsInt : int |
The same as sublayerId but represented as an integer type (read-only).
Note: The underlying property is represented as a 64-bit integer type. See Accessing 64-bit integer properties from QML.
This property was introduced in Esri.ArcGISRuntime 100.3.
sublayerType : Enums.ArcGISSublayerType |
Returns the sublayer's type (read-only).
A sublayer may be an image sublayer or a tiled sublayer, or the type may be unknown.
See also Enums.ArcGISSublayerType.
sublayers : ArcGISSublayerListModel |
The sublayers represented as a list model of ArcGISSublayer.
visible : bool |
