Good Day, I want to create a very basic app login hence I am looking for alternatives to OAuth, Token Auth etc. I just want a login page with a Username and Password. That's it, nothing else. Therefore, I decided to use Secure Storage with the thought process being.......a username and password is stored by a user initially. When the user opens the app in the future, they enter the same user name and password and hit 'Login'. So, this login checks the keychain to ensure the password is correct and then allows access to the app by opening a new window.  I modified the Secure Storage code to include a 'Login' Button however nothing happens when I hit Login. Therefore, I assume that the problem lies with the Login button. Can I be guided on how to fix this? Thank you. Below is the code: import QtQuick 2.7 import QtQuick.Layouts 1.1 import QtQuick.Controls 2.1 import QtQuick.Controls.Material 2.1 import QtGraphicalEffects 1.0 import QtQuick.Dialogs 1.2 import QtQuick.Window 2.1 import ArcGIS.AppFramework 1.0 import ArcGIS.AppFramework.Controls 1.0 //import Esri.ArcGISRuntime 100.1 import ArcGIS.AppFramework.SecureStorage 1.0 import "controls" as Controls App {     id: app     width: 400     height: 750     function units(value) {         return AppFramework.displayScaleFactor * value     }     property real scaleFactor: AppFramework.displayScaleFactor     property int baseFontSize : app.info.propertyValue("baseFontSize", 15 * scaleFactor) + (isSmallScreen ? 0 : 3)     property bool isSmallScreen: (width || height) < units(400)     property string insertSuccessMessage: qsTr ("Inserted into Keychain")     property string removeSuccessMessage: qsTr ("Removed from Keychain")     property string failMessage:qsTr("Something Went Wrong")     property color successColor: Material.color(Material.Teal)     property color errorColor: Material.color(Material.DeepOrange)     Page {         anchors.fill: parent         header: ToolBar{             id:header             width: parent.width             height: 50 * scaleFactor             Material.background: "#8f499c"             Controls.HeaderBar{}         }         // sample starts here ------------------------------------------------------------------         contentItem: Rectangle {             anchors.top:header.bottom             ColumnLayout {                 spacing: 5 * scaleFactor                 anchors.horizontalCenter: parent.horizontalCenter                 // Insert key in this text field                 TextField {                     id: username                     placeholderText: "Username"                     echoMode: passwordVisible.checked === true ?

Good Day, I have been using the code below to zoom to the device's location and add a point feature based on the device's current location by clicking any where on the screen. The feature is being added to the service table however there is no/null geometries for each point therefore it is not showing up on the map. How can I fix this? import QtQuick 2.7 import QtQuick.Controls 2.1 import QtQuick.Controls.Material 2.1 import QtQuick.Layouts 1.1 import QtGraphicalEffects 1.0 import ArcGIS.AppFramework 1.0 import ArcGIS.AppFramework.Controls 1.0 import Esri.ArcGISRuntime 100.2 import QtPositioning 5.3 import QtSensors 5.3 MapView{     id: mapView     Map{         id: map         initUrl: "http://melbournedev.maps.arcgis.com/home/webmap/viewer.html?webmap=24ba3f20e7424c67989e64ec740384f8"         FeatureLayer {             id: featureLayer             selectionColor: "cyan"             selectionWidth: 3             // declare as child of feature layer, as featureTable is the default property             ServiceFeatureTable {                 id: featureTable                 url: "https://services1.arcgis.com/NUSHso3rgWERZOFF/arcgis/rest/services/TestPoint1/FeatureServer/0"                 // make sure edits are successfully applied to the service                 onApplyEditsStatusChanged: {                     if (applyEditsStatus === Enums.TaskStatusCompleted) {                         console.log("successfully added feature");                     }                 }                 // signal handler for the asynchronous addFeature method                 onAddFeatureStatusChanged: {                     if (addFeatureStatus === Enums.TaskStatusCompleted) {                         // apply the edits to the service                         featureTable.applyEdits();                     }                 }             }         }     }     locationDisplay {         positionSource: positionSource         compass: compass     }     PositionSource {         id: positionSource         active: true         property bool isInitial: true         onPositionChanged: {             if(map.loadStatus === Enums.LoadStatusLoaded && isInitial) {                 isInitial = false;                 zoomToCurrentLocation();             }         }     }     Compass {         id: compass     }     function zoomToCurrentLocation(){         positionSource.update ();         var currentPositionPoint = ArcGISRuntimeEnvironment.createObject ("Point", {x: positionSource.position.coordinate.longitude, y: positionSource.position.coordinate.latitude, spatialReference: SpatialReference.createWgs84()});         var centerPoint = GeometryEngine.project(currentPositionPoint, mapView.spatialReference);         var viewPointCenter = ArcGISRuntimeEnvironment.createObject("ViewpointCenter",{center: centerPoint, targetScale: 10000});         mapView.setViewpointWithAnimationCurve(viewPointCenter, 2.0,  Enums.AnimationCurveEaseInOutCubic);     }     //!

Good Day, How can I get a position/location point from the locationDisplay? I want to get that point. I am using the code below but I nothing happens when I click the button. import QtQuick 2.7 import QtQuick.Controls 2.1 import QtPositioning 5.3 import QtSensors 5.3 import ArcGIS.AppFramework 1.0 import ArcGIS.AppFramework.Controls 1.0 import Esri.ArcGISRuntime 100.2 App {     id: window     visible: true        //Create MapView that contains a Map     MapView {                 anchors.fill: parent             //Nest the Map as a child of the MapView         Map {     //Nest the ArcGISTiledLayer to add it as one of the Basemap's baselayers             ArcGISTiledLayer {                 url: "https://services.arcgisonline.com/arcgis/rest/services/Polar/Antarctic_Imagery/MapServer"             }         }             locationDisplay {                 positionSource: PositionSource {                     id: ps                 }             }         onStatusChanged: {             if (loadstatus === Enums.MapStatusReady) {                 ps.active = true;             }         }             }              Button {             anchors {                 left: parent.left                 top: parent.top                 margins: 10             }             text: "get point"             onClicked: {                 var point = mapView.locationDisplay.mapPoint;                 console.log("x", point.x, "y", point.y, "wkid", point.spatialReference.wkid)             }             }         } ...
