@Kanzakiryu , Hi and thanks for reaching out to the team. We do implement http caching in the Qt API, so on subsequent access of the same map/basemap it should speed up. There's nothing specific I can offer to speed up loading that particular basemap, but if you're concerned about your app displaying something incomplete, we do have a layerViewStateChanged signal you can connect to to show a loading screen or something similar if that would help. That way you can make sure that everything is in the active state before displaying the map. https://developers.arcgis.com/qt/cpp/api-reference/esri-arcgisruntime-mapquickview.html#layerViewStateChanged  https://developers.arcgis.com/qt/cpp/api-reference/esri-arcgisruntime-layerviewstate.html#statusFlags I hope that helps. Here is some extra info about our http caching class: https://developers.arcgis.com/qt/cpp/api-reference/esri-arcgisruntime-networkcacheconfiguration.html  ... View more

Hi @KennSebesta , I have some code that I was able to add to that existing sample code that should help. This is added within the MapView declaration. MapView { id: mapView anchors.fill: parent // identify layers on mouse click onMouseClicked: { // for every EncLayer, clear all selection on every mouse click map.operationalLayers.forEach(function(layer) { if (layer.layerType === Enums.LayerTypeEncLayer) layer.clearSelection(); }); const screenX = mouse.x; const screenY = mouse.y; const tolerance = 12; const returnPopups = false; const maxResults = 3; mapView.identifyLayersWithMaxResults(screenX, screenY, tolerance, returnPopups, maxResults); } // handle the identify results onIdentifyLayersStatusChanged: { if (identifyLayersStatus !== Enums.TaskStatusCompleted) return; console.log("identified on", identifyLayersResults.length, "layers"); // for the result of every layer in the map... for (let i = 0; i < identifyLayersResults.length; i++) { const identifyLayerResult = identifyLayersResults[i]; let layerContent = identifyLayerResult.layerContent; let encFeatures = identifyLayerResult.geoElements; // for all geoelements of that layer's results... for (let j = 0; j < encFeatures.length; ++j) { let encFeature = encFeatures[j]; layerContent.selectFeature(encFeature); console.log("found EncFeature", encFeature.description, encFeature.acronym, JSON.stringify(encFeature.attributes.attributesJson)); } } }   With that code you can identify the EncFeatures to locate the Safety Contour Line feature(s), and get their geometry. As mentioned in the other post, there is no way to query for features and search for only the Contour features, but you can identify them and get their geometry. In the sample code you can adjust the max number of features identified on each mouse click. Let us know if this is helpful. ... View more

@FatmaAkdemir , We do have a sample that adds a polyline on mouse clicks with our Service Area sample. https://github.com/Esri/arcgis-runtime-samples-qt/tree/master/ArcGISRuntimeSDKQt_CppSamples/Routing/ServiceArea This code snippet shows the mouseClicked handler and how to get the projected point for the click location https://github.com/Esri/arcgis-runtime-samples-qt/blob/master/ArcGISRuntimeSDKQt_CppSamples/Routing/ServiceArea/ServiceArea.cpp#L259-L286 And this code block shows have to add points to a geometry builder and symbolize this on the graphics overlay. https://github.com/Esri/arcgis-runtime-samples-qt/blob/master/ArcGISRuntimeSDKQt_CppSamples/Routing/ServiceArea/ServiceArea.cpp#L295-L309 We are working on the Sketch Editor for Qt and hope to have this ready for the next release. That will be a big improvement in the sketching experience. We also have a ShowLocationHistory sample that adds points as "breadcrumbs" to a polyline via PolylineBuilder. https://github.com/Esri/arcgis-runtime-samples-qt/tree/master/ArcGISRuntimeSDKQt_CppSamples/Maps/ShowLocationHistory  ...
