Detailed Description

Implementation of threaded rendering for vector layers.

Note
added in 2.4

Constructor & Destructor Documentation

QgsVectorLayerRenderer::QgsVectorLayerRenderer ( QgsVectorLayer layer,
QgsRenderContext context 
)
QgsVectorLayerRenderer::~QgsVectorLayerRenderer ( )

Member Function Documentation

bool QgsVectorLayerRenderer::render ( )
virtual

Do the rendering (based on data stored in the class)

Implements QgsMapLayerRenderer.

void QgsVectorLayerRenderer::setGeometryCachePointer ( QgsGeometryCache cache)

where to save the cached geometries

Note
The way how geometries are cached is really suboptimal - this method may be removed in future releases
