virtual QgsSymbolList symbols(QgsRenderContext &context) const
Returns list of symbols used by the renderer.
virtual void stopRender(QgsRenderContext &context)
Must be called when a render cycle has finished, to allow the renderer to clean up.

Stores renderer properties to an XML element.

Returns a list of attributes required by this renderer.

To be overridden.
virtual bool accept(QgsStyleEntityVisitorInterface *visitor) const
Accepts the specified symbology visitor, causing it to visit all symbols associated with the renderer...
virtual void startRender(QgsRenderContext &context, const QgsFields &fields)
Must be called when a new render cycle is started.

Container of fields for a vector layer.
Definition: qgsfields.h:45
A paint effect which draws a glow outside of a picture.
The class is used as a container of context for various read/write operations on other objects.
Contains information about the context of a rendering operation.
An interface for classes which can visit style entity (e.g.
