Member Function Documentation

createCallout()

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

overridevirtual

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

Ownership of the callout is transferred to the caller.

Implements QgsCalloutAbstractMetadata.

Definition at line 34 of file qgscalloutsregistry.cpp.

createCalloutWidget()

QgsCalloutWidget * QgsCalloutMetadata::createCalloutWidget ( QgsVectorLayer *  )

overridevirtual

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 from QgsCalloutAbstractMetadata.
