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

Rendering 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

Member Function Documentation

◆ filterExpression()

QString QgsVectorTileBasicRendererStyle::filterExpression ( ) const

inline

Returns filter expression (empty filter means that all features match)

Definition at line 75 of file qgsvectortilebasicrenderer.h.

◆ geometryType()

Qgis::GeometryType QgsVectorTileBasicRendererStyle::geometryType ( ) const

inline

Returns type of the geometry that will be used (point / line / polygon)

Definition at line 70 of file qgsvectortilebasicrenderer.h.

◆ isActive()

bool QgsVectorTileBasicRendererStyle::isActive ( int zoomLevel ) const

inline

Returns whether the style is active at given zoom level (also checks "enabled" flag)

Definition at line 140 of file qgsvectortilebasicrenderer.h.

◆ isEnabled()

bool QgsVectorTileBasicRendererStyle::isEnabled ( ) const

inline

Returns whether this style is enabled (used for rendering)

Definition at line 85 of file qgsvectortilebasicrenderer.h.

◆ layerName()

QString QgsVectorTileBasicRendererStyle::layerName ( ) const

inline

Returns name of the sub-layer to render (empty layer means that all layers match)

Definition at line 65 of file qgsvectortilebasicrenderer.h.

◆ maxZoomLevel()

int QgsVectorTileBasicRendererStyle::maxZoomLevel ( ) const

inline

Returns the maximum zoom level index (negative number means no limit).

The style will be rendered if the zoom level is less than or equal to the maximum zoom.

Warning: This differs from the handling of the max zoom as defined in the MapBox Style Specifications, where the style is rendered only if the zoom level is less than the maximum zoom.

See also: setMaxZoomLevel(); minZoomLevel()

Definition at line 137 of file qgsvectortilebasicrenderer.h.

◆ minZoomLevel()

int QgsVectorTileBasicRendererStyle::minZoomLevel ( ) const

inline

Returns the minimum zoom level index (negative number means no limit).

The style will be rendered if the zoom level is greater than or equal to the this level.

See also: setMinZoomLevel(); maxZoomLevel()

inline

Sets name of the sub-layer to render (empty layer means that all layers match)

Definition at line 63 of file qgsvectortilebasicrenderer.h.

◆ setMaxZoomLevel()

void QgsVectorTileBasicRendererStyle::setMaxZoomLevel ( int maxZoom )

inline

Sets maximum zoom level index (negative number means no limit).

The style will be rendered if the zoom level is less than or equal to maxZoom.

Warning: This differs from the handling of the max zoom as defined in the MapBox Style Specifications, where the style is rendered only if the zoom level is less than the maximum zoom.
