Hey Mauricio
To load a featurelayer in a QT app in gml code use:
FeatureLayer{
id: featureLayer
ServiceFeatureTable{
url: featureServiceURL
}
}
this has to be loaded inside a mapview though. But if you do not add a Map {} part to the code there will not be displayed a map
after this the featurelayer should be able to be call on the id
hope this can help
best
