Map canvas is a class for displaying all GIS data types on a canvas.
Definition: qgsmapcanvas.h:109
A renderer that automatically displaces points with the same position.
Base class for renderer settings widgets.
Represents a vector layer which manages a vector based data sets.
virtual QgsFeatureRendererV2 * renderer()=0
return pointer to the renderer (no transfer of ownership)
virtual void setMapCanvas(QgsMapCanvas *canvas)
Sets the map canvas associated with the widget.
