Add a feature

Question

Hi,

I am trying to add a feature as soon as an app is opened. I tried the code below but it is not working. The location is turning on however, the feature is not showing up. How can I fix this?

Component.onCompleted: {

//Qt.openUrlExternally("%1/home/webmap/viewer.html?webmap=%2".arg(app.portalUrl).arg(portalItem.id))

if (!mapView.locationDisplay.started) {

mapView.locationDisplay.start()

mapView.locationDisplay.autoPanMode = Enums.LocationDisplayAutoPanModeRecenter

// create attributes json for the new feature

var featureAttributes = {"xyz" : "xyz"};

// create a new feature using the mouse's map point

var point = mapView.locationDisplay.mapLocation

var feature = featureTable.createFeatureWithAttributes(featureAttributes, point);

// add the new feature to the feature table

featureTable.addFeature(feature);

} else {

mapView.locationDisplay.stop()

}

Hi Giatri, Please make sure the feature layer has been loaded (if adding it to the map) or initialized (if not the part of the view). For e.g. here I am adding the feature as soon as the featurelayer loads. Also Make your point is not undefined. I hope this helps. Nakul FeatureLayer { id: featureLayer // declare as child of feature layer, as featureTable is the default property ServiceFeatureTable { id: featureTable url: "http://sampleserver6.arcgisonline.com/arcgis/rest/services/DamageAssessment/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(); } } } onLoadStatusChanged: { if(loadStatus === Enums.LoadStatusLoaded){ // var point = ArcGISRuntimeEnvironment.createObject("Point", {x: -11975850.0012, y: 4274812.4997999966, spatialReference: SpatialReference.createWebMercator()}); var point = mapView.locationDisplay.mapLocation var featureAttributes = {"typdamage" : "Minor", "primcause" : "Earthquake"}; // create a new feature using the mouse's map point var feature = featureTable.createFeatureWithAttributes(featureAttributes, point); // add the new feature to the feature table featureTable.addFeature(feature); } } } }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

No feature is being created, nothing is happening.

My guess is it might be a timing issue between the "Completed.onCompleted" being triggered and the location display is ready.

Can you check if we have the point before adding the feature to featureTable?
