Member Function Documentation

createNodeForEntry()

QgsHistoryEntryNode * QgsProcessingHistoryProvider::createNodeForEntry ( const QgsHistoryEntry & entry, const QgsHistoryWidgetContext & context )

overridevirtual

Creates a new history node for the given entry.

Since

QGIS 3.32

Reimplemented from QgsAbstractHistoryProvider.

Definition at line 416 of file qgsprocessinghistoryprovider.cpp.

createTest

void QgsProcessingHistoryProvider::createTest ( const QString & command )

signal

Emitted when the provider needs to create a Processing test with the given python command.

Since

QGIS 3.32

executePython

void QgsProcessingHistoryProvider::executePython ( const QString & commands )

signal

Emitted when the provider needs to execute python commands in the Processing context.

Since

QGIS 3.32

id()

QString QgsProcessingHistoryProvider::id ( ) const

overridevirtual

Returns the provider's unique id, which is used to associate existing history entries with the provider.

Implements QgsAbstractHistoryProvider.

Definition at line 47 of file qgsprocessinghistoryprovider.cpp.

portOldLog()

void QgsProcessingHistoryProvider::portOldLog

(

)

Ports the old text log to the history framework.

This should only be called once – calling multiple times will result in duplicate log entries

Definition at line 52 of file qgsprocessinghistoryprovider.cpp.

updateNodeForEntry()

void QgsProcessingHistoryProvider::updateNodeForEntry ( QgsHistoryEntryNode * node, const QgsHistoryEntry & entry, const QgsHistoryWidgetContext & context )

overridevirtual

Updates an existing history node for the given entry.

Since

QGIS 3.32

Reimplemented from QgsAbstractHistoryProvider.

Definition at line 421 of file qgsprocessinghistoryprovider.cpp.
