QgsProcessingAlgorithmDialogBase

Base class for processing algorithm dialogs.

class qgis.gui.QgsProcessingContextGenerator

Bases: object

processingContext(self) → QgsProcessingContext | None

This method needs to be reimplemented in all classes which implement this interface and return a Processing context.

Note that ownership of the context is not transferred - it is intended that subclasses return a pointer to a context which they have already created and own.

Return type:

Optional[QgsProcessingContext]
