WMTS services can have several layers. You can use the ArcGIS Maps SDK for Qt to explore the layers available from a service. This would commonly be used to enable a browsing experience where users can choose which layers they want to display at run time.
How to use the sample
The layer will be displayed automatically. Pan and zoom to explore the map.
How it works
To display a WMTS layer directly from a URL:
Create a WmtsService object using the URL of the WMTS service.
Create a WmtsLayer object with the ID of the layer to display.
To explore layers from a WMTS service:
Create a WmtsService object using the URL of the WMTS service.
After loading the WMTS service, get the list of WmtsLayerInfo objects from the service info of the WMTS service.
Use one of the layer infos to create the WMTS layer.
Create a basemap with the WMTS layer and set it to the map.
