overridevirtual

Sets the units to use for sizes and widths within the symbol layer.

Individual symbol layer subclasses will interpret this in different ways, e.g., a marker symbol layer may use it to specify the units for the marker size, while a line symbol layer may use it to specify the units for the line width.

Parameters

unit	output units

See also: outputUnit()

Reimplemented from QgsSymbolLayer.

◆ setUseWholeShape()

void QgsShapeburstFillSymbolLayer::setUseWholeShape ( bool useWholeShape )

inline

Sets whether the shapeburst fill should be drawn using the entire shape.

Parameters

useWholeShape Set to true if shapeburst should cover entire shape. If false, setMaxDistance is used to calculate how far from the boundary of the shape should be shaded

See also: useWholeShape; setMaxDistance

◆ startRender()

void QgsShapeburstFillSymbolLayer::startRender ( QgsSymbolRenderContext & context )

overridevirtual

Called before a set of rendering operations commences on the supplied render context.

This is always followed by a call to stopRender() after all rendering operations have been completed.

Subclasses can use this method to prepare for a set of rendering operations, e.g. by pre-evaluating paths or images to render, and performing other one-time optimisations.

See also: startFeatureRender(); stopRender()

Implements QgsSymbolLayer.

Definition at line 1272 of file qgsfillsymbollayer.cpp.

◆ stopRender()

void QgsShapeburstFillSymbolLayer::stopRender ( QgsSymbolRenderContext & context )

overridevirtual

Called after a set of rendering operations has finished on the supplied render context.

This is always preceded by a call to startRender() before all rendering operations are commenced.

Subclasses can use this method to cleanup after a set of rendering operations.

See also: startRender(); stopFeatureRender()

Implements QgsSymbolLayer.

Definition at line 1281 of file qgsfillsymbollayer.cpp.

◆ usesMapUnits()

bool QgsShapeburstFillSymbolLayer::usesMapUnits ( ) const

overridevirtual

Returns true if the symbol layer has any components which use map unit based sizes.

Since: QGIS 3.18

Reimplemented from QgsSymbolLayer.

Definition at line 1741 of file qgsfillsymbollayer.cpp.

◆ useWholeShape()

bool QgsShapeburstFillSymbolLayer::useWholeShape ( ) const

inline

Returns whether the shapeburst fill is set to cover the entire shape.

Returns: true if shapeburst fill will cover the entire shape. If false, shapeburst is drawn to a distance of maxDistance from the polygon's boundary.

See also: setUseWholeShape; maxDistance
