Subgroup: Processing

Class: QgsProcessingFeedback

class qgis.core.QgsProcessingFeedback

Bases: qgis._core.QgsFeedback

Base class for providing feedback from a processing algorithm.

This base class implementation silently ignores all feedback reported by algorithms. Subclasses of QgsProcessingFeedback can be used to log this feedback or report it to users via the GUI.

pushDebugInfo()

pushDebugInfo(self, info: str)

Pushes an informational message containing debugging helpers from the algorithm.

pushInfo()

pushInfo(self, info: str)

Pushes a general informational message from the algorithm. This can be used to report feedback which is neither a status report or an error, such as “Found 47 matching features”.

pushDebugInfo()

receivers()
reportError(self, error: str, fatalError: bool = False)

Reports that the algorithm encountered an error while executing.

If fatalError is true then the error prevented the algorithm from executing.

sender()
senderSignalIndex()
setProgressText(self, text: str)

Sets a progress report text string. This can be used in conjunction with setProgress() to provide detailed progress reports, such as “Transformed 4 of 5 layers”.
