Member Function Documentation

◆ algorithm()

const QgsProcessingAlgorithm* QgsProcessingAlgorithmConfigurationWidget::algorithm ( ) const

inline

Returns the algorithm instance associated with this widget.

See also: setAlgorithm()

Since: QGIS 3.6

Definition at line 98 of file qgsprocessingalgorithmconfigurationwidget.h.

◆ configuration()

virtual QVariantMap QgsProcessingAlgorithmConfigurationWidget::configuration ( ) const

pure virtual

Read the current configuration from this widget.

◆ createExpressionContext()

QgsExpressionContext QgsProcessingAlgorithmConfigurationWidget::createExpressionContext ( ) const

overridevirtual

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

Since: QGIS 3.0

Implements QgsExpressionContextGenerator.

Definition at line 45 of file qgsprocessingalgorithmconfigurationwidget.cpp.

◆ registerProcessingContextGenerator()

void QgsProcessingAlgorithmConfigurationWidget::registerProcessingContextGenerator ( QgsProcessingContextGenerator * generator )

Registers a Processing context generator class that will be used to retrieve a Processing context for the widget when required.

Since: QGIS 3.6

Definition at line 40 of file qgsprocessingalgorithmconfigurationwidget.cpp.

◆ setAlgorithm()

void QgsProcessingAlgorithmConfigurationWidget::setAlgorithm ( const QgsProcessingAlgorithm * algorithm )

Sets the algorithm instance associated with the widget.

See also: algorithm()

Since: QGIS 3.6

Definition at line 35 of file qgsprocessingalgorithmconfigurationwidget.cpp.

◆ setConfiguration()

virtual void QgsProcessingAlgorithmConfigurationWidget::setConfiguration ( const QVariantMap & configuration )

pure virtual

Set the configuration which this widget should represent.

◆ setWidgetContext()

void QgsProcessingAlgorithmConfigurationWidget::setWidgetContext ( const QgsProcessingParameterWidgetContext & context )

virtual

Sets the context in which the Processing algorithm widget is shown, e.g., the parent model algorithm, a linked map canvas, and other relevant information which allows the widget to fine-tune its behavior.

Subclasses should take care to call the base class method when reimplementing this method.

See also: widgetContext()

Since: QGIS 3.6

Definition at line 25 of file qgsprocessingalgorithmconfigurationwidget.cpp.

◆ widgetContext()

const QgsProcessingParameterWidgetContext & QgsProcessingAlgorithmConfigurationWidget::widgetContext ( ) const

Returns the context in which the Processing algorithm widget is shown, e.g., the parent model algorithm, a linked map canvas, and other relevant information which allows the widget to fine-tune its behavior.
