Detailed Description

Stores metadata about one renderer class.

Note

It's necessary to implement createRenderer() function. In C++ you can use QgsRendererV2Metadata convenience class.

Member Function Documentation

virtual QgsFeatureRendererV2* QgsRendererV2AbstractMetadata::createRenderer ( QDomElement &  elem )

pure virtual

Return new instance of the renderer given the DOM element.

Returns NULL on error. Pure virtual function: must be implemented in derived classes.

Implemented in QgsRendererV2Metadata.

virtual QgsFeatureRendererV2* QgsRendererV2AbstractMetadata::createRendererFromSld ( QDomElement &  elem, QGis::GeometryType  geomType  )

inlinevirtual

Reimplemented in QgsRendererV2Metadata.

Definition at line 62 of file qgsrendererv2registry.h.

virtual QgsRendererV2Widget* QgsRendererV2AbstractMetadata::createRendererWidget ( QgsVectorLayer *  layer, QgsStyleV2 *  style, QgsFeatureRendererV2 *  oldRenderer  )

inlinevirtual

Return new instance of settings widget for the renderer.

Returns NULL on error.

The oldRenderer argument may refer to previously used renderer (or it is null). If not null, it may be used to initialize GUI of the widget from the previous settings. The old renderer does not have to be of the same type as returned by createRenderer(). When using oldRenderer make sure to make a copy of it - it will be deleted afterwards.
