Sounds like you're on the right track. Here is an example of using a polygon to find points that are within it. Just click on a state and you can see what cities are within that state: import QtQuick 2.6 import QtQuick.Controls 1.4 import Esri.ArcGISRuntime 100.3 ApplicationWindow {     id: appWindow     width: 800     height: 600     title: "SpatialQuery"     // add a mapView component     MapView {         anchors.fill: parent         // set focus to enable keyboard navigation         focus: true         // add a map to the mapview         Map {             // add the BasemapTopographic basemap to the map             BasemapTopographic {}             FeatureLayer {                 id: statesLayer                 ServiceFeatureTable {                     id: statesTable                     url: "http://sampleserver6.arcgisonline.com/arcgis/rest/services/USA/MapServer/2"                 }             }             FeatureLayer {                 id: citiesLayer                 ServiceFeatureTable {                     id: citiesTable                     url: "http://sampleserver6.arcgisonline.com/arcgis/rest/services/USA/MapServer/0"                     onQueryFeaturesStatusChanged: {                         if (queryFeaturesStatus !== Enums.TaskStatusCompleted)                             return;                         var resultIter = queryFeaturesResult.iterator;                         while (resultIter.hasNext) {                             var feat = resultIter.next();                             citiesLayer.selectFeature(feat)                             console.log("City:", feat.attributes.attributeValue("areaname"));                         }                     }                 }             }         }         onMouseClicked: {             // clear selection and identify layers             statesLayer.clearSelection();             citiesLayer.clearSelection();             identifyLayerWithMaxResults(statesLayer, mouse.x, mouse.y, 10, false, 1)         }         onIdentifyLayerStatusChanged: {             if (identifyLayerStatus !== Enums.TaskStatusCompleted)                 return;             // select the state layer that was identified             var result = identifyLayerResult.geoElements[0];             statesLayer.selectFeature(result);             // find all the cities in that polygon             // create the params             var queryParams = ArcGISRuntimeEnvironment.createObject("QueryParameters");             queryParams.geometry = result.geometry;             queryParams.spatialRelationship = Enums.SpatialRelationshipIntersects;             // query the table             citiesTable.queryFeatures(queryParams)         }     } } ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

The issue is that there is a mixture of our QML and C++ APIs in your example. We have one API which is purely QML, and that is the API that AppStudio uses. You can tell if you are using the QML API because you will see "import Esri.ArcGISRuntime 100.x" in the code - this is the QML plugin we build and ship. If you instead want to use our C++ API, you can utilize the MapQuickView to expose the MapView to QML, and write your business logic in C++ and your UI in QML. The different development paradigms are highlighted in this doc - Qt SDK best practices—ArcGIS Runtime SDK for Qt | ArcGIS for Developers  Long story short - if you create a new project and select the "ArcGIS Runtime Qt Quick QML" template, everything should work. If you prefer to use the C++ API, there will be more work involved - for starters, you will need to remove the "import Esri.ArcGISRuntime 100.x" from your ScaleBar.qml, expose the various Q_PROPERTYs that you need, etc. ...
