When i perform a zoom if i dont have tiles for that area, the upper level tiles was shown instead of disappear...
How i can disable that feature?
Jorge,
I don't see any property or method to disable cache on the WebTiledLayer documentation of ArcGIS Runtime SDK for Qt/QML.
I am including ArcGIS Runtime SDK for Qt to see anyone in this group know the answer to this.
Thank you,
Erwin
I don't have good data to test if this works or not, but can you try setting the noDataTileBehavior property (inherited from ImageTiledLayer) to Enums.NoDataTileBehaviorBlank - https://developers.arcgis.com/qt/latest/qml/api-reference/enums-nodatatilebehavior.html
Lucas Danzinger I have the same behavior with every one of the enum options.
There you have a good data to test it. (attached)
A greeting!
Can you share your code please?
WebTiledLayer{ visible: map.layerVisibilityOfflineTopoFire; templateUrl: AppFramework.userHomeFolder.filePath("ArcGIS/AppStudio/Data/MyMarvelousApp/") + "/topofire/{level}/{col}/{row}.jpg;
noDataTileBehavior: Enums.NoDataTileBehaviorBlank;
}
Hi Jorge-
It seems like the no data behavior is not working on WebTiledLayer. This seems like a bug. As a workaround, could you try implementing a custom basemap with ServiceImageTiledLayer instead? It is more code but very customizable and works as you describe your requirements:
