◆ addCalloutPosition()

void QgsCallout::QgsCalloutContext::addCalloutPosition ( const QgsCalloutPosition & position )

inline

Adds a rendered callout position.

The position details such as the callout line origin and destination should be populated by the callout subclass during rendering operations.

Note: the feature ID, layer ID and provider ID of the QgsCalloutPosition will be automatically populated.
