A model for showing available data sources and other items in a structured tree.
Container of fields for a vector layer.
Definition: qgsfields.h:45
Contains information about the context in which a processing algorithm is executed.
Base class for all parameter definitions which represent file or layer destinations,...
Contains settings which reflect the context in which a Processing parameter widget is shown,...
An interface for objects which can create sets of parameter values for processing algorithms.
Defines the parameters used to remap features when creating a QgsRemappingProxyFeatureSink.
