Member Function Documentation

addMarker()

KoMarker * KoMarkerCollection::addMarker

(

KoMarker *

marker

)

Add marker to collection

The collection checks if a marker with the same content exists and if so deletes the passed marker and returns a pointer to an existing marker. If no such marker exists it adds the marker and return the same pointer as passed. Calling that function passes ownership of the marker to this class.

Parameters

marker

Marker to add

Returns

pointer to marker that should be used. This might be different to the marker passed
