153 std::vector< LayerRenderJob > mSecondPassLayerJobs;
Class that stores computed placement from labeling engine.
Abstract base class for map renderer jobs which use custom painters.
Job implementation that renders everything sequentially using a custom painter.
const std::vector< LayerRenderJob > & jobs() const
Abstract base class for map rendering implementations.
virtual void waitForFinished()=0
Block until the job has finished.
virtual bool usedCachedLabels() const =0
Returns true if the render job was able to use a cached labeling solution.
virtual bool isActive() const =0
Tell whether the rendering job is currently running in background.
virtual QgsLabelingResults * takeLabelingResults()=0
Gets pointer to internal labeling engine (in order to get access to the results).
virtual void cancel()=0
Stop the rendering job - does not return until the job has terminated.
virtual void cancelWithoutBlocking()=0
Triggers cancellation of the rendering job without blocking.
The QgsMapSettings class contains configuration for rendering of the map.
