You can subclass ServiceImageTiledLayer like explained in the detailed description here - https://developers.arcgis.com/qt/latest/cpp/api-reference/esri-arcgisruntime-serviceimagetiledlayer.html

Attached is a working example hitting the online URLs. You should be able to modify the code to point to local file URLs instead of online URLs. Make sure to update the full extent and tile info to match your tile cache.

for local URLs you can use the `file:///` prefix instead of `http://`

To update the name, modify the custom image tiled layer URL in the setTileRequest function
