Detailed Description

A model for representing the sublayers present in a URI.

QgsProviderSublayerModel is designed to present a tree view of the sublayers available for a URI, including any vector, raster or mesh sublayers present.

Additionally, QgsProviderSublayerModel can include some non-sublayer items, e.g. in order to represent other content available for a URI, such as embedded project items. The non-sublayer items can be added by calling addNonLayerItem().
