Detailed Description
Some layer types contain sublayers. Sublayers contain properties, some of which can be accessed before the layer is loaded. These include:
idnamemaxScaleminScalevisible
Other sublayer properties can be accessed only after the Layer is loaded.
See also PopupSource and Loadable.
Member Function Documentation
[signal] void ArcGISSublayer::doneLoading (Esri::ArcGISRuntime::Error loadError )
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.
[signal] void ArcGISSublayer::loadStatusChanged (Esri::ArcGISRuntime::LoadStatus loadStatus )
Signal emitted when the loadStatus changes for this object.
This function was introduced in Esri::ArcGISRuntime 100.1.
See also Loadable.
[override virtual] ArcGISSublayer::~ArcGISSublayer ()
Destructor.
[override virtual] bool ArcGISSublayer::canChangeVisibility () const
Reimplements: LayerContent::canChangeVisibility() const.
Returns whether the sublayer's visibility can be changed.
See LayerContent.
[override virtual] void ArcGISSublayer::cancelLoad ()
Reimplements: Loadable::cancelLoad().
See Loadable.
This function was introduced in Esri::ArcGISRuntime 100.1.
QString ArcGISSublayer::definitionExpression () const
Returns the sublayer's definition expression.
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 function was introduced in Esri::ArcGISRuntime 100.1.
qint64 ArcGISSublayer::id() const
Returns the sublayer's ID.
[override virtual] bool ArcGISSublayer::isAutoFetchLegendInfos () const
Reimplements: LayerContent::isAutoFetchLegendInfos() const.
Returns whether legend infos are automatically fetched by the sublayer's legend info list model.
See LayerContent.
bool ArcGISSublayer::isLabelsEnabled () const
Returns whether the sublayer's labels are displayed.
This function was introduced in Esri::ArcGISRuntime 100.1.
[override virtual] bool ArcGISSublayer::isPopupEnabled () const
Reimplements: PopupSource::isPopupEnabled() const.
Returns whether the Popup is enabled on the PopupSource.
bool ArcGISSublayer::isScaleSymbols () const
Returns whether the sublayer renders its symbols based on scale.
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 function was introduced in Esri::ArcGISRuntime 100.1.
[override virtual] bool ArcGISSublayer::isShowInLegend () const
Reimplements: LayerContent::isShowInLegend() const.
