class QgsPointDistanceRenderer: QgsFeatureRenderer

{

%Docstring
|
|
An abstract base class for distance based point renderers (e.g., clusterer and displacement renderers).
|
|
QgsPointDistanceRenderer handles calculation of point clusters using a distance based threshold.
|
|
Subclasses must implement drawGroup() to handle the rendering of individual point clusters
|
|
in the desired style.
