Detailed Description

Definition of map rendering of a subset of vector tile data.

The subset of data is defined by:

sub-layer name

geometry type (a single sub-layer may have multiple geometry types)

filter expression

Renering is determined by the associated symbol (QgsSymbol). Symbol has to be of the same type as the chosen geometryType() - i.e. QgsMarkerSymbol for points, QgsLineSymbol for linestrings and QgsFillSymbol for polygons.

It is possible to further constrain when this style is applied by setting a range of allowed zoom levels, or by disabling it.

Since: QGIS 3.14
