Detailed Description
Basic implementation of the labeling interface.
The configuration is kept in layer's custom properties for backward compatibility.
- Note
- added in 2.12

Member Function Documentation
◆ provider()
|
overridevirtual |
Factory for label provider implementation.
Implements QgsAbstractVectorLayerLabeling.
Definition at line 39 of file qgsvectorlayerlabeling.cpp.
◆ save()
|
overridevirtual |
Return labeling configuration as XML element.
Implements QgsAbstractVectorLayerLabeling.
Definition at line 52 of file qgsvectorlayerlabeling.cpp.
◆ settings()
|
overridevirtual |
Get associated label settings.
In case of multiple sub-providers with different settings, they are identified by their ID (e.g. in case of rule-based labeling, provider ID == rule key)
Implements QgsAbstractVectorLayerLabeling.
Definition at line 60 of file qgsvectorlayerlabeling.cpp.
◆ type()
|
overridevirtual |
Unique type string of the labeling configuration implementation.
Implements QgsAbstractVectorLayerLabeling.
Definition at line 47 of file qgsvectorlayerlabeling.cpp.
