Property Documentation
[read-only] geoPackageFeatureTables : list<GeoPackageFeatureTable> |
A list of GeoPackageFeatureTable contained in this GeoPackage (read-only).
[read-only] geoPackageRasters : list<GeoPackageRaster> |
A list of GeoPackageRaster contained in this GeoPackage (read-only).
[read-only] loadError : Error |
Returns the load error (read-only).
Note: load errors are also reported on the error property and emit the errorChanged signal.

A local file path to a GeoPackage on disk.
Signal Documentation
geoPackageFeatureTablesChanged() |
Emitted when the geoPackageFeatureTables property changes.
Note: The corresponding handler is onGeoPackageFeatureTablesChanged.
geoPackageRastersChanged() |
Emitted when the geoPackageRasters property changes.
Note: The corresponding handler is onGeoPackageRastersChanged.
loadErrorChanged() |
loadStatusChanged() |
Emitted when the loadStatus property of the elevation source changes.
Note: The corresponding handler is onLoadStatusChanged.
See also Loadable.
pathChanged() |

Method Documentation
void cancelLoad() |
See also Loadable.
void close() |
Close the GeoPackage.
This should only be called once you have finished accessing the data in the GeoPackage. For example: remove feature layers and rasters from maps and release feature tables. Attempts to access a GeoPackage after it is closed will fail, resulting in an error. After closing a GeoPackage, the underlying file it references can be deleted.
