void | progressChanged (double progress) |
Emitted when the feedback object reports a progress change. More... | |
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.

QgsProcessingFeedback::QgsProcessingFeedback | ( | bool | logFeedback = true | ) |
Constructor for QgsProcessingFeedback.
If logFeedback is true
, then all feedback received will be directed to QgsMessageLog.
Definition at line 29 of file qgsprocessingfeedback.cpp.
|
virtual |
Returns the HTML formatted contents of the log, which contains all messages pushed to the feedback object.
Reimplemented in QgsProcessingMultiStepFeedback.
Definition at line 142 of file qgsprocessingfeedback.cpp.
|
virtual |
Pushes an informational message containing a command from the algorithm.
This is usually used to report commands which are executed in an external application or as subprocesses.
Reimplemented in QgsProcessingMultiStepFeedback.
Definition at line 86 of file qgsprocessingfeedback.cpp.
|
virtual |
Pushes a console feedback message from the algorithm.
This is used to report the output from executing an external command or subprocess.
Reimplemented in QgsProcessingMultiStepFeedback.
Definition at line 104 of file qgsprocessingfeedback.cpp.
|
virtual |
Pushes an informational message containing debugging helpers from the algorithm.
Reimplemented in QgsProcessingMultiStepFeedback.
Definition at line 95 of file qgsprocessingfeedback.cpp.
|
virtual |
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".
Reimplemented in QgsProcessingMultiStepFeedback.
Definition at line 77 of file qgsprocessingfeedback.cpp.
void QgsProcessingFeedback::pushVersionInfo | ( | const QgsProcessingProvider * | provider = nullptr | ) |
Pushes a summary of the QGIS (and underlying library) version information to the log.
Definition at line 113 of file qgsprocessingfeedback.cpp.
|
virtual |
Pushes a warning informational message from the algorithm.
This should only be used sparsely as to maintain the importance of visual queues associated to this type of message.
Reimplemented in QgsProcessingMultiStepFeedback.
Definition at line 68 of file qgsprocessingfeedback.cpp.
|
virtual |
Reports that the algorithm encountered an error while executing.
If fatalError is true
then the error prevented the algorithm from executing.
Reimplemented in QgsProcessingBatchFeedback, and QgsProcessingMultiStepFeedback.
Definition at line 59 of file qgsprocessingfeedback.cpp.
|
virtual |
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".
Reimplemented in QgsProcessingMultiStepFeedback.
Definition at line 35 of file qgsprocessingfeedback.cpp.
|
virtual |
Returns the plain text contents of the log, which contains all messages pushed to the feedback object.
Reimplemented in QgsProcessingMultiStepFeedback.
