Add Geodatabase layer to Map

Question

How to add local Geodatabase feature class grammatically to the Map object created thru: ArcGISRuntimeEnvironment.createObject("Map",{});  ?

Thank you

Proper way:

var geodb = ArcGISRuntimeEnvironment.createObject("Geodatabase", {

path: outputGdb});

geodb.loadStatusChanged.connect(function () {

if (Enums.LoadStatusLoaded === geodb.loadStatus) {

var tables = geodb.geodatabaseFeatureTables;

var t1 = geodb.geodatabaseFeatureTablesByTableName["offline_test"];

var fc = ArcGISRuntimeEnvironment.createObject("FeatureLayer", 
                           {featureTable: t1});

var map = ArcGISRuntimeEnvironment.createObject("Map",{});

map.operationalLayers.append(fc);

mapView.map = map;

}

})

Thank you,

I am trying to create the Map object from Geodatabase layer:

var geodb = ArcGISRuntimeEnvironment.createObject("Geodatabase", {path: outputGdb});
var t1 = geodb.geodatabaseFeatureTablesByTableName["offline_test"];

var fc = ArcGISRuntimeEnvironment.createObject("FeatureLayer", {featureTable: t1

});
var map2 = ArcGISRuntimeEnvironment.createObject("Map",{});

map2.operationalLayers.append(fc);

mapView.map = map2;

Map loads with no data, is this wrong way to load GB data programmatically?

Thank you,

Here is some code to do this - arcgis-runtime-samples-qt/FeatureLayer_Geodatabase.qml at master · Esri/arcgis-runtime-samples-qt · GitHub

Essentially you need to:

- Create a Geodatabase object via the path to the local file - Geodatabase QML Type | ArcGIS for Developers

- Iterate through the list of GeodatabaseFeatureTable objects - Geodatabase QML Type | ArcGIS for Developers

- For each feature table, create a Feature Layer by setting the featureTable property - FeatureLayer QML Type | ArcGIS for Developers

- Add the FeatureLayers to the Map's operational layer list model
