qreal QgsSymbolV2RenderContext::alpha ( ) const

inline

Get alpha transparency 1 for opaque, 0 for invisible.

Definition at line 231 of file qgssymbolv2.h.

const QgsFeature* QgsSymbolV2RenderContext::feature ( ) const

inline

Current feature being rendered - may be null.

Definition at line 243 of file qgssymbolv2.h.

const QgsFields* QgsSymbolV2RenderContext::fields ( void  ) const

inline

Fields of the layer.

Currently only available in startRender() calls to allow symbols with data-defined properties prepare the expressions (other times fields() returns null)
