Member Function Documentation

createCallout()

virtual QgsCallout* QgsCalloutAbstractMetadata::createCallout ( const QVariantMap &  properties, const QgsReadWriteContext &  context  )

pure virtual

Create a callout of this type given the map of properties.

Ownership of the callout is transferred to the caller.

Implemented in QgsCalloutMetadata.

createCalloutWidget()

QgsCalloutWidget * QgsCalloutAbstractMetadata::createCalloutWidget ( QgsVectorLayer *  )

virtual

Creates a widget for configuring callouts of this type.

Can return nullptr if there's no GUI required.

Ownership of the widget is transferred to the caller.

Reimplemented in QgsCalloutMetadata.

Definition at line 25 of file qgscalloutsregistry.cpp.
