Class: QgsProcessingParameterDefinitionWidget

class qgis.gui.QgsProcessingParameterDefinitionWidget

Bases: PyQt5.QtWidgets.QWidget

A widget which allow users to specify the properties of a Processing parameter.

New in version 3.10.

QgsProcessingParameterDefinitionWidget(type: str, context: QgsProcessingContext, widgetContext: QgsProcessingParameterWidgetContext, definition: QgsProcessingParameterDefinition = None, algorithm: QgsProcessingAlgorithm = None, parent: QWidget = None) Constructor for QgsProcessingParameterDefinitionWidget, for a parameter of the specified type.

The context argument must specify a Processing context, which will be used by the widget to evaluate existing definition properties such as default values. Similarly, the widgetContext argument specifies the wider GUI context in which the widget will be used.

The optional definition argument may be used to provide a parameter definition to use to initially populate the widget’s state.

Additionally, the optional algorithm parameter may be used to specify the algorithm or model associated with the parameter.
